Powerful Energy For Everyone

A new addition to our list of renewable energy documentaries is an incredible film by David Chernushenko "Powerful - Energy For Everyone". 

Challenging where our energy comes from and who profits from it can seem a little eccentric... After all, not everyone has solar panels bolted above the doorstep. Green economy educator David Chernushenko does, and they generate more than enough energy to go around. So why cant he share it? New technologies mean that energy security is within our grasp, but harsh resistance is still being met. Debunking some of the spin of the big energy lobby, David embarks on a global journey to discover what a sustainable future might actually look like.

Trading sex for resources

The title really says it all. Not much further commentary needed. Care for another example? How about bower birds?

Just Like Penguins And Other Primates, People Trade Sex For Resources

Female penguins mate with males who bring them pebbles to build egg nests. Hummingbirds mate to gain access to the most productive flowers guarded by larger males.

New research shows that even affluent college students who dont need resources will still attempt to trade sexual currency for provisions, said Daniel Kruger, research scientist at the University of Michigan School of Public Health.

The exchange of resources for sex---referred to by scientists as nuptial gifts---has occurred throughout history in many species, including humans, Kruger said. The male of the species offers protection and resources to the female and offspring in exchange for reproductive rights. For example, an arranged marriage can be considered a contract to trade resources.

However, the recent findings suggest that such behaviors are hard wired, and persist no matter how much wealth, resources or security that people obtain.

The top Australian cleantech predictions for 2012

Giles Parkinson has left The Climate Spectator to start a new site called REneweconomy. One of the first posts has a range of comments from leaders of Australian cleantech companies - The top Australian cleantech predictions for 2012.

It is clear that 2012 will be a critical year for cleantech in Australia. Costs for many technologies are falling rapidly, but critical decisions will be made about renewable energy targets and support mechanisms.

The carbon price will finally be introduced, the shape and purpose of the $10 billion Clean Energy Finance Corporation will be decided, reviews will be held into the Renewable Energy Target and many of the regulatory issues surrounding the energy industry, and on solar tariffs, tough decisions may be taken on programs such as Solar Flagships, and more funding will start to flow into cleantech R&D. And, of course, there will be the final version of energy White Paper.

We asked the heads of Australia’s cleantech companies and industry groups what they predicted for the year. This is what they said:

Lane Crockett, general manager, Pacific Hydro

“For the Chinese, 2012 is the year of the dragon, but for Australia 2012 must be the year we move on renewable energy. After a number of years of policy uncertainty driven by constant adjustments to the LRET and a protracted carbon price debate we should start to see some confidence return to the market as these important reforms are hopefully now well and truly bedded down. Critically, 2012 sees compliance obligations of energy retailers under the LRET scheme start to escalate substantially.

“This will help to soak up any remaining oversupply of renewable energy certificates and should signal a strong surge in contracting activity. If liable parties are tardy and don’t prepare sufficiently for future escalating obligations they may find themselves paying substantially more for certificates than they were anticipating and rue the lost opportunity to lock in long-term low cost compliance. Underlying this opportunity is the combination of excess wind turbine manufacturing capacity and a strong Australian dollar leading to some of the lowest cost turbines for some time. Hopefully 2012 will be a year to remember for all the right reasons.”

Evan Thornley, CEO Better Place

“2012 is the year of the electric car. It’s the year we’ll look back on and say: that’s when the transformation started – the biggest and most profound transformation to transport in over a century. Every major car-maker in the world has electric models either in production or in development. The auto industry has recognised it. Capital markets have recognised it. Governments have recognised it. Here in Australia, electric cars will arrive on our shores in mass volumes for the first time in the second half of the year. This means people can finally exercise a choice to drive something faster, quieter, cheaper and greener.”

Miles George, CEO, Infigen Energy

In the Australian renewable energy sphere I expect:

· the effectiveness of the large scale renewable energy target scheme will be significantly enhanced as residual surplus small scheme RECs are absorbed, and the scheduled review of the scheme confirms a stable future regulatory regime for the large scale renewable energy industry

· political partisanship on climate change response will diminish, and carbon emissions pricing will become much more widely accepted.

· wind and solar PV technologies will continue to significantly improve their cost competitiveness with burning fossil fuels, whilst other renewable energy technologies will struggle to keep up with the pace

· carbon capture and storage technology will increasingly be recognised as a pipe dream ...

Jack Curtis, head of Australia and Asia-Pacific, First Solar

‘2012 will mark the year that Australia’s first utility-scale solar project becomes a reality – with the Greenough River Solar Farm to be fully operational mid-year. In the second half of last year, the Federal Government’s ‘Clean Energy Future’ package was released, and with it the possibility of two new independent bodies: the Australian Renewable Energy Agency (ARENA) and the Clean Energy Finance Corporation (CEFC). This year will be critical as it relates to the establishment of their respective mandates and their ability to support new project development in 2012.

“The Gillard Government has suggested that the CEFC could be functioning by mid-year. Both of these bodies will be vital to encouraging the next level of renewable adoption in Australia. Their ability to operate autonomously in concert with the private sector is also essential. If implemented effectively, our view is that the CEFC should alleviate the medium-term commercial viability gap that exists for emerging renewable technologies. Most importantly, the CEFC needs to facilitate and encourage private sector participation and adoption of new technologies.

“We had some positive movement from state governments last year, especially the ACT, with the announcement of a ‘reverse auction’ tariff program being established for large-scale solar. Outside the ACT, we also expect to see more utility-scale solar PV projects in development throughout Australia, with Western Australia being a key location given its strong macro drivers for solar. First Solar’s goal is to be the most bankable execution mechanism for utility-scale solar projects in Australia with a focus on driving the adoption of solar more broadly and a significant reduction in the cost of delivering solar electricity.”

Michael Ottaviano, CEO, Carnegie Wave Energy

My predictions for 2012 ….

· Solar pv will continue towards retail parity price driven by cheap Chinese manufacturing dominance,

· Wind turbine manufacturing will move in the same way to emerging market sand with the same result – costs also approaching pricing parity (although, unlike solar, at the wholesale level) and the slow decline of western turbine manufacturers (only investment in innovation and development of proprietary technology will be effective against China’s cheap cost of labour and capital),

· Billions of Euros will be committed in the EU offshore wind market – France will be the latest country to announce multi-GW projects

· The start of the Australian carbon price and resilience of domestic economy leads to renewed local interest in cleantech focused on carbon sequestering technologies such as Pacific Pyrolysis

· A shake out in marine energy as a few well capitalized and advanced developers deliver first commercial scale projects alongside major EU industrial partners including Carnegie who will commence construction of its first multi MW CETO project, ...

Wave Power Pilot Due For 2013

NineMSN reports that a biomimicry inspired wave power project will be piloted in Victoria soon - Wave energy to power 300 Victorian homes. The Warrnambool Standard has more - Port Fairy on a $14m ocean power wave.

A world-first wave energy project which mimics the movement of seaweed and kelp through the water will power hundreds of homes in Victorias southwest.

The $14 million BioWAVE project is a single wave energy unit that will be anchored to the sea floor 30 metres underwater and about 800 metres from the shore at a site four kilometres west of Port Fairy.

The 450kW unit will be connected to the energy grid and power 300 homes by early 2013.
The project is an example of biomimicry, in which biological traits are used in engineered systems.

The Victorian government has put $5 million towards the project and other partners include AGL Energy Bluescope Steel, Lend Lease, Swinburne University, the University of Melbourne and the University of Sydney.

Not good news for antioxidant therapies

Forget The Antioxidants? Researchers Cast Doubt On Role Of Free Radicals In Aging (2/17/09)

For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells ability to repair the damage they cause, and the cells age.

An industry of "alternative" antioxidant therapies -- such as Vitamin E or CoQ10 supplements in megadose format -- has sprung up as the result of this theory. However, clinical trials have not shown that these treatments have statistically significant effects.

And now researchers at McGill University, in a study published in the February issue of the journal PLoS Genetics, are calling the entire oxidative stress theory into question. Their results show that some organisms actually live longer when their ability to clean themselves of this toxic molecule buildup is partially disabled. Collectively, these molecules are known as reactive oxygen species, or ROS for short.

Author summary of the open-access paper:

Deletion of the Mitochondrial Superoxide Dismutase sod-2 Extends Lifespan in Caenorhabditis elegans

In this paper, we examine the oxidative stress theory of aging using C. elegans as a model system. This theory proposes that aging results from the accumulation of molecular damage caused by reactive oxygen species (ROS). To test this theory, we examined the effect of deleting each of the five individual superoxide dismutase (SOD) genes on lifespan and sensitivity to oxidative stress. Since SOD acts to detoxify ROS, the oxidative stress theory predicts that deletion of sod genes should increase oxidative stress and decrease lifespan. However, in contrast to yeast, flies, and mice, where loss of either cytoplasmic or mitochondrial SOD results in decreased lifespan, we find that none of the sod deletion mutants in C. elegans exhibits a shortened lifespan despite increased sensitivity to oxidative stress. Surprisingly, we find that sod-2 mutant worms have extended lifespan and even worms with the primary cytoplasmic, mitochondrial, and extracellular sod genes deleted can live longer than wild-type worms. By examining genetic interactions with other genes known to extend lifespan and by comparing the phenotype of worms lacking sod-2 to that of known long-lived mitochondrial mutants such as clk-1 or isp-1, we provide evidence that the loss of sod-2 extends lifespan through alteration of mitochondrial function.

Saudi Arabia did not make up for lost Libyan oil production

Stuart at Early Warning has a post on global oil production in the wake of the Libyan crisis (see the original for lots more graphs) - Saudi Arabia did not make up for Libyan Oil.

The OPEC MOMR came out late yesterday, but it adds to the picture from the IEA report mentioned yesterday morning. In particular, I can now present revised graphs for total liquid fuel production. Heres the last three year view (not zero scaled):

Note that the rise thats been going in since last fall has now been abruptly interrupted by the Libyan situation, and total oil production has fallen by about 0.5mbd. This is about 0.6% of global production, but given that the world economy has been growing rapidly and needing about another 0.5mbd/month, the shortfall over what would have happened in a counterfactual world with no Middle Eastern unrest is more like 1.2% of global production.

In terms of the price production picture, this has put us much more into territory akin to the 2005-2008 oil shock:

We can put the situation almost entirely down to two things: the fact that Libyan production has plummeted, and that Saudi Arabia has made no significant move to compensate. In fact, Saudi Arabia slowed down production increases that it had been making in prior months. First, heres all the Libyan data currently available:

So the world has abruptly lost something like 1.3mbd of oil production between mid February and March. Now there were a lot of news reports in the business press at the time this was first happening that Saudi Arabia was going to make up the difference. ...

Now that the stats are out, we can see that this was total bull. Will that fact be all over the business press? My bet is youll have to read some obscure blog called Early Warning to find out what really happened. First off, heres all the Saudi production data I have (not zero scaled to better show changes):

Indeed Saudi production has increased to around 9mbd, but the timing makes it clear this has nothing to do with Libya. For better comparison, I have put both the Libyan and Saudi averages on the same graph (only since 2005), with the scales adjusted to allow easy comparison. In particular, note that the size of the units on both scales is the same, so similar vertical moves in both curves mean the same amount of oil, but the Saudi scale (left hand scale) has been shifted to put the Saudi curve next to the Libyan one (right scale):

I have circled the March data in each case. You can see what was going on. The Saudis were slowly increasing their production from last fall through February, presumably in response to growing global demand and rising prices. But then, in March, when Libyan production went into freefall, they put on the brakes and did almost nothing to make up for the shortage.

The burning question is: why? Back in 2006, when their production started to gradually decline from 9.5mbd even as global oil prices were in the worst spike since the 1970s, I was an advocate of the view that the decline was largely involuntary: theyd never produced more than 9.5mbd, theyd underinvested for decades, and some of their big fields were getting very tired (particular northern Ghawar and Abqaiq) and they were starting a big rash of new projects and ramping up their rig counts at the same time.

I see current events differently. The reduction in late 2008 was clearly voluntary to support prices in the face of the great recession. Theres no new projects announced, and the rig count hasnt taken off. So my take is that the failure to increase production to compensate for Libya is deliberate. We can only speculate, but my guess is that, having watched how the west has helped to ease Mubarak and Ben-Ali out of power and is intervening in Libya to the same end, the Saudi regime is in no mood to care about our desire for more oil. Instead, they are very much in the mood to build as large a war chest as possible with which to appease their own population, strengthen their defense measures, etc.

So, instead of Saudi production increasing to compensate for Libya, total world production decreased, and oil prices went up sharply to enforce the necessary conservation on the worlds oil consumers. ...

So, heres the latest data on the discount of the three Saudi grades of oil, to Brent (with a seven week moving average applied to reduce noise):

You can see that these discounts have actually fallen sharply in recent weeks to levels usually seen only in the depths of recessions when the Saudis are trying to raise prices. So rather than trying to flood the market with their oil to help supplies post Libya, the Saudis are ramping back and extracting every dollar they can get.

2 GW Solar Thermal Power Plant Planned For Kuwait

CSP Today has an article on a 50 MW solar thermal power plant with 10 hours of integrated energy storage to be built in Kuwait - the first stage in a plant which is eventually planned to generate 2 GW - CSP makes a grand entry into Kuwait

Kuwait recently started the bidding process for the 70 MW Shagaya Multi Technology Renewable Energy Power Park, which will include a 50 MW CSP plant with 10 hours thermal storage in addition to 10MW PV and 10MW wind. ...

There is much more on Kuwait’s renewable energy agenda, however, given that the state-owned Shagaya project is the first of a three-phased master plan proposed by KISR. The second phase will expand the plant’s capacity by 930 MW to bring it up to 1,000 MW, and the third by another 1,000 MW to ultimately reach 2,000 MW by 2030. By then, the complex will generate more than 5,000,000 MWh of power every year, fulfilling the demands of nearly 100,000 households. A 100-square-kilometre (38.6 square-mile) site in Shagaya – a desert area 100km (62 miles) west of Kuwait City, near the borders with Saudi Arabia and Iraq – has been designated for the complex. And while the first phase will be financed by the government, the second and third phases are expected to be offered to investors on a Build-Operate-Transfer basis for 25 years. - See more at: http://social.csptoday.com/emerging-markets/csp-makes-grand-entry-kuwait#sthash.2JgVY40V.dpuf

Oslo On The Hunt For Rubbish To Burn

The NYT has a report on the increasing competition to find rubbish to burn in Europe - A City That Turns Garbage Into Energy Copes With a Shortage. Its not exactly the cradle to cradle manufacturing economy that we should be aspiring to but I guess its better than landfill.

This is a city that imports garbage. Some comes from England, some from Ireland. Some is from neighboring Sweden. It even has designs on the American market.

“I’d like to take some from the United States,” said Pal Mikkelsen, in his office at a huge plant on the edge of town that turns garbage into heat and electricity. “Sea transport is cheap.”

Oslo, a recycling-friendly place where roughly half the city and most of its schools are heated by burning garbage — household trash, industrial waste, even toxic and dangerous waste from hospitals and drug arrests — has a problem: it has literally run out of garbage to burn.

The problem is not unique to Oslo, a city of 1.4 million people. Across Northern Europe, where the practice of burning garbage to generate heat and electricity has exploded in recent decades, demand for trash far outstrips supply. “Northern Europe has a huge generating capacity,” said Mr. Mikkelsen, 50, a mechanical engineer who for the last year has been the managing director of Oslo’s waste-to-energy agency.

Yet the fastidious population of Northern Europe produces only about 150 million tons of waste a year, he said, far too little to supply incinerating plants that can handle more than 700 million tons. “And the Swedes continue to build” more plants, he said, a look of exasperation on his face, “as do Austria and Germany.”

Stockholm, to the east, has become such a competitor that it has even managed to persuade some Norwegian municipalities to deliver their waste there. By ship and by truck, countless tons of garbage make their way from regions that have an excess to others that have the capacity to burn it and produce energy.

System for Predicting Wave Energy Could Double Wave Power Generation

EcoGeek has a post on research into optimising wave power generation - System for Predicting Wave Energy Could Double Wave Power Generation.

As part of a new study on wave power, the University of Exeter and Tel Aviv University have come up with a system that predicts the power of waves in order to maximize wave energy devices ability to generate energy from the sea. The researchers found that this system could potentially double the amount of wave energy generated by a device.

Phys.org reports, "The research focused on point absorbers, commonly-used floating devices with parts that move in response to waves, generating energy which they feed back to the grid. Point absorbers are already known to be much more efficient in the amount of energy they produce if their response closely matches the force of the waves and previous research has looked at trying to increase this efficiency. However, this is the first study that has focused on increasing the devices efficiency by predicting and controlling internal forces of the device caused by forthcoming waves."

Wave energy potential is huge. Its been estimated that it could power the world twice over and the UK, where this study was conducted, could be powered twice over just by utilizing wave energy generators along its coastlines. So far, wave energy technologies havent gained traction the way that solar and wind technologies have because the ocean is a very inhospitable place. Wave energy generators have to be able to withstand the force of each wave.

This new system predicts the power of the incoming wave, allowing the device to respond in a way that extracts the most amount of energy. This controlled reaction not only increases the efficiency of the device, but protects it from damage from rough seas. Where most current wave technologies would be shut off during a storm, a prediction system could allow the wave generator to keep operating effectively.

The University of Exeter is now working with Ocean Power Technologies, one of the largest wave energy companies, to further test the results and develop better technologies based on this research.

Fracking A new dawn for misplaced optimism

The Independent has a jaundiced look at the shale gas boom in the US - Fracking: A new dawn for misplaced optimism.

You would think we were swimming in oil. The International Energy Agencys (IEA) latest World Energy Outlook forecasts that the United States will outstrip Saudi Arabia as the worlds largest producer by 2017, becoming "all but self-sufficient in net terms" in energy production. While the "peak oil" pessimists are clearly wrong, so is a simplistic picture of fossil fuel abundance.

When the IEA predicts an increase in "oil production" from 84 million barrels a day in 2011 to 97 in 2035, it is talking about "natural gas liquids and unconventional sources", which includes a big reliance on "fracking" for shale gas. Conventional oil output will stay largely flat, or fall.

The IEA has been exposed before as having, under US pressure, artificially inflated official reserve figures. And now US energy consultants Ruud Weijermars and Crispian McCredie say there is strong "basis for reasonable doubts about the reliability and durability of US shale gas reserves". The New York Times found that state geologists, industry lawyers and market analysts privately questioned "whether companies are intentionally, and even illegally, overstating the productivity of their wells and the size of their reserves." And former UK chief government scientist Sir David King has concluded that the industry had overstated world oil reserves by about a third. In Nature, he dismissed notions that a shale gas boom would avert an energy crisis, noting that production at wells drops by as much as 90 per cent within the first year.

The rapid decline rates make shale gas distinctly unprofitable. Arthur Berman, a former Amoco petroleum geologist, cites the Eagle Ford shale, Texas, where the decline rate is so high that simply to keep production flat, they will have to drill "almost 1,000 wells" a year, requiring "about $10bn or $12bn a year just to replace supply". In all, "it starts to approach the amount of money needed to bail out the banking industry. Where is that money to come from?"

In September, the leader of the US shale gas revolution, Chesapeake Energy, sold $6.9bn of gas fields and pipelines to stave off collapse. Four months ago Exxons CEO, Rex Tillerson, told a private meeting: "Were making no money. Its all in the red." The worst-case scenario is that several large oil companies at once face financial distress. Then, says Berman, "you may have a couple of big bankruptcies or takeovers and everybody pulls back, all the money evaporates, all the capital goes away."

Nordic Awarded exclusive mandate to raise funds for Bio degradable bottle water company

The global bottled water market valuation grew by 7% in 2006 to reach a value of $60,938.1 million. The volume of bottled water grew by 8.1% in 2006 to 115,393.5 million liters. In 2011, the market is forecast to have a value of $86,421.2 million, an increase of 41.8% since 2006. In 2011, the market is forecast to have a volume of 174,286.6 million liters, an increase of 51% since 2006.

The global rate of consumption more than quadrupled between 1990 and 2005. Purified water is currently the leading global seller, with U.S. companies dominating the field, and natural spring water, purified water and flavored water being the fastest-growing market segments.

Effects of bottled water

The major criticism of bottled water concerns the bottles themselves. Individual use bottled water is generally packaged in Polyethylene terephthalate (PET). According to a NAPCOR study, PET water bottles account for 50% of all the PET bottles and containers collected by curbside recycling, and the recycling rate for water bottles is 23.4%, an increase over the 2006 rate of 20.1%. PET bottled water containers make up one-third of 1 percent of the waste stream in the United States.

The International Bottled Water Association also reports that the average weight of a plastic bottle water was 13.83 grams in 2007, compared to 18.90 grams in 2000, representing a 26.7% decline. Pepsi-Co has since introduced a bottle weighing 10.9 grams and using 20 percent less plastic, which it says is the lightest bottle of its kind that is nationally distributed.

An estimated 50 billion bottles of water are consumed per annum in the US and around 200 billion bottles globally.

Green algae as a source for hydrogen production

Hydrogen is considered by many energy experts as one of the most promising future fuels, mostly because of its almost unlimited potential. There are many ongoing researches which study different options on how to produce hydrogen directly from sunlight because by doing so hydrogen is both  renewable as well as environmentally friendly energy source.

There are different biological ways that allow the production of hydrogen with one of the most interesting being using photosynthetic microorganisms such as green algae. During the process of photosynthesis water is split into hydrogen ions (H+) and electrons (e-) which can later be combined into hydrogen gas with the use of special enzymes.

It has been know for quite some time that green algae can use energy from the sun through photosynthesis to produce hydrogen through their own metabolism, however this process is usually accompanied with insufficient efficiency.

The latest study from Swedish scientists has discovered that most of the hydrogen production is driven directly by solar energy meaning that there is a good possibility that in the future it will be possible to control the green algae so that the efficiency becomes significantly higher than it is today.

The previous studies, on the other hand, claimed that most of the hydrogen gas gets its energy from other paths in the metabolism of the green algae. This would lead to conclusion that green algae are no more efficient as energy crops than plants.

This new study gives hope that green algae could become major fuel source in years to come.

Canberra grants pave way for world’s biggest wave turbine

Giles Parkinson at ReNewEconomy has an article on the release of some government funding to wave power companies BioPower (mentioned in this post on biomimicry) and long time developer OceanLinx to build pilot plants (following an earlier funding round to Carnegie Corp in WA) - Canberra grants pave way for world’s biggest wave turbine.

The Australian government as upped its investment in two nascent, Australian-developed wave energy technologies, announcing new grants worth almost $10 million to help bring the two new systems to the market, including what is believed to be the world’s biggest wave energy turbine.

The government is providing $5.6 million to BioPower Systems to install a 250kW full-scale pilot plant of its bioWAVE technology off the coast of Victoria, and is also providing just under $4 million to Oceanlinx, to install a 1MW demonstration plan of its Greenwave technology in South Australia.

Both grants are being made under the $126 million Emerging Renewables program, and follow an earlier $9 million grant to Carnegie Wave Energy, which is building a $31 million, 2MW grid-connected demonstration of its CETO technology near Fremantle in Western Australia.

BioPower CEO Tim Finnigan said the grant, along with a $5 million grant from the Victorian state government, means that its $15 million project was now fully funded. “This puts us into a position to complete the project, get it on the grid, and prove the technology at scale,” he told RenewEconomy. “It’s a pretty big development for us.”

The technology is best described with an image, see below. It’s designed to lay flat on the ocean floor when the waves become too big (it calculated this to be around 1 per cent of the time).

It is designed to absorb energy both at the surface and below. It is mounted on sea-floor, the demonstrator will be in about 30m of water, and the array of buoyant floats, sways back-and-forth in tune with the waves, and the energy contained in this motion is converted to electricity by an onboard self-contained power conversion module, and is delivered through a cable.

However, the first demonstration plan will weigh 400 tonnes when it is installed at a site 4kms from Port Fairy on the southern coast of Victoria. “We not trying to prove a light-weight structure right now,” Finnigan says. “We will carve our way to that over time.”

Like Carnegie Energy, Finnigan says the long term goal for wave energy has to be to match wind – which means capital costs of around $2 million/megawatt and a levellised cost of energy at $100/MWh or below. He says BioPower has a four-stage plan to reach that target by the end of the decade. ...

Meanwhile, Oceanlinx says it believes its GreenWave device (see below) is the first in the world to be rated at 1MW, and its efficiency has improved 50 per cent since an earlier, smaller version that was deployed near Port Kembla in NSW. The 20m by 20m structure, around 17m high, will sit in around 10m of water. It features an oscillating water column, with the turbine and other moving parts above the waterline. The 2,000 tonne concrete structure will sit on the ocean floor.

CEO Ali Baghaei says this demonstration unit will have an LCOE of 28c/kWh, which will fall to 16c/kWh once 5MW have been installed and to below 10c/kWh once 75MW have been installed. The initial project will cost $7.2 million, with the balance coming from a recent $8 million fund raising from existing investors. ...

Resources and Energy Minister Martin Ferguson said the grants made Australia “one of the world’s largest supporters” of wave energy technology. “Wave energy is still very much an emerging technology and this funding will position Australia as a global leader in developing this technology,” he said in a statement, adding that wave energy had the potential of providing 1300 terawatt hours per year, or about five times Australia’s total electricity requirements.

Giant tidal device set for tests off Orkney

The BBC has a report on testing of a tidal power design in Scotland - Giant tidal device set for tests off Orkney.

A giant underwater turbine which could form the worlds first tidal power array has been deployed off Orkney. The 100ft-high 1MW (megawatt) Hammerfest Strom HS1000 device was installed by the European Marine Energy Centre (EMEC). It will now undergo tests in preparation for larger-scale production and deployment.

Scottish Power Renewables (SPR) hopes to use the design for a planned array in the Sound of Islay. The device has been developed by Hammerfest Strom, a company partly owned by SPR parent firm Iberdrola. Its substructure was constructed in the Arnish Yard, near Stornoway, in Lewis.

SPR intends to develop a 10MW tidal array in Islay after receiving planning consent from the Scottish government in March this year.

The HS1000 device, which SPR said could power the annual electricity needs of 500 homes, is expected to be fully operational in early 2012. The tests will also help to finalise the timetable for the Islay project, with machines being installed "as early as feasible" between 2013 and 2015.

Good prospects for local wind mapping company

ECOS Magazine has a look at a company trying to gain an edge in wind farm development using sophisticated mapping techniques to identify optimal wind generation locations - Good prospects for local wind-mapping company.

When Queensland recently announced the construction of a 720?kilometre high-voltage transmission link between Townsville and Mount Isa, it opened a door for Australian-based company Windlab Systems to advance the development of the country’s largest wind farm – a 750 megawatt facility near Hughenden, southwest of Townsville.

It’s a major coup for the company, which began when CSIRO scientists Dr Keith Ayotte and Dr Nathan Steggel headed up a spinoff to commercialise a CSIRO wind modelling and mapping program.

Their WindScape program determines a site’s wind resource potential by generating high-resolution maps from existing meteorological data of mean annual wind speed and annual energy yield for target sites. Dr Ayotte describes it as a remote ‘prospecting’ tool for initial assessment of site viability without the need for field measurements.

However, good wind conditions don’t guarantee a successful wind farm. The program’s wind information is therefore combined with powerline and land?use data to assess proximity of grid connections and land?use types in the vicinity. This integration of data reduces risk by shortening development timeframes. It also increases the likelihood of selected sites leading to commercially viable projects that address local community and environmental concerns.

The wind-mapping program is complemented by a turbulence-flow modelling program, which ensures turbine longevity through minimising operations and maintenance costs.

Today, Windlab has evolved from a wind-mapping consultancy to a wind-farm developer that uses its mapping and modelling technologies to identify large-scale projects and take them from concept to financial close. ...

Dr Ayotte, now Windlab’s Chief Technology Officer, says one of the biggest constraints in Australia is the sparse electricity grid.

‘You tend to find yourself scratching around for places that are windy and near the grid,’ he says. ‘We have the advantage, because we can really burrow down into the data to find less obvious locations.’

Collgar Wind Farm in Western Australia, Oaklands Hill in Victoria and Coopers Gap in southern Queensland are all examples of ‘less obvious’ inland locations identified through WindScape.

Once a grid connection point is identified, the next constraint is the high cost of connecting to the transmission line.

‘That can kill the economics of your wind farm, unless it is big enough that you can spread the cost among a lot of turbines,’ says Dr Ayotte. Windlab focuses on large-scale wind farms, from 100–200 megawatt capacity and upwards. ...

Despite this uncertainty, the prospects for Windlab look good. Its projects in Australia and South Africa are multiplying, and Queensland’s proposed $1.5 billion Kennedy wind farm project – an installation of up to 300 turbines – is set to create 1000 jobs and boost Queensland’s power generation capacity by six per cent.

9 999 EV — Shai Agassi’s Formula For A Disruptive EV Takeover Apple Style

CleanTechnica has a series of articles from Better Place founder Shai Agassi on the process for electric vehicles replacing petrol powered cars - Part 1 Part 2 Part 3 Part 4.

In the previous three parts of this series we have looked at the lessons the auto industry can learn from Tesla. I identified four key takeaways all carmakers should use as the foundation for their electric vehicle plans. The lessons all add up to the following principle:

Design a desirable Electric car that is upgradable over the years. Separate between car ownership and the battery, since batteries continue to improve exponentially. Finally, don’t force this new category of product through a mixed channel selling both ICE cars and EVs.

The recommendation to mass volume carmakers, those making more than 1 million cars per year, was not to try and beat Tesla in the category it created and dominates – Luxury electric cars. Tesla predicts it will make 21,000 cars this year – Nothing in the scale these massive carmakers operate enables to make any meaningful profit when they make a model at such low volume.

Instead, my recommendation was to make a desirable electric crossover, with space and power, then equip it with enough of a battery to get great range – say 150 to 200 miles. Most crucially of all – do not sell that battery. Instead, partner with an operator that owns the batteries, the one you buy with the car, the ones available on the road, and the ones drivers will use over the life of the car. The operator will package batteries together with electricity and offer those as “electric-miles” offered for a fixed monthly fee. For the sake of argument, let’s make that monthly fee equal to the cost of a weekly stop at the gas station today – roughly $300 a month.

Picture a great car serviced through an energy model that allows you to drive it unlimited miles but pay a flat monthly fee as you do so. #Like

The last remaining question was the price point that will make this electric crossover so disruptive as to drive demand through the roof. We pegged “infinite demand” at the imaginary market size of 1M cars worldwide. Mind you, that is only 1% of cars sold each year.

The final claim of Part III was:

If the market leader priced such a car starting at $9,999 after all incentives, without the cost of the battery (remember there is an operator that owns that battery) – a new category will be born, with demand far surpassing any imagination.

The metaphor I used was the iPad. At launch the first iPad was priced at $499, far below the price point for a powerful laptop. Compare that with Windows’ TabletPCs that asked for a premium above the price of a laptop, due to the “Tablet features”, such as touch. The result – TabletPC was always considered a niche segment where meaningless numbers were sold over the first 5-10 years in the market. Apple’s genius pricing of its first iPad at sub $500, combined with the fact that it was “an object of desire” disrupted the laptop market and shifted non-buyers (people who didn’t consider the need for a tablet before) into “Tablet devices”.
