Electric vehicle dreams the charge ahead

The weekend SMH had a prominent (and long) article on electric vehicles - Electric dreams: the charge ahead.
A social researcher, Mark McCrindle, of McCrindle Research, says his studies have shown while most people are concerned about the environment, they are not prepared to pay more to make a difference.

A recent survey found 96 per cent of respondents believed people have played some part in climate change but only 28 per cent directly intend to cut their carbon emissions.

Thats a view backed up by Evan Thornley, the chief executive officer of BetterPlace Australia, who is trying to orchestrate a network of recharging points. He believes the electric car revolution is unstoppable but not for environmental concerns.

The fundamental reason for that is simple, Thornley says. The cost of batteries is coming down and the cost of petrol is going up. That creates a pretty fundamental inevitability of driving moving from petrol to electric.

It is a massive business opportunity … youve got $30 billion worth of petrol being sold to customers that hate the product. They love their car, they hate their petrol.

BetterPlace has announced plans to begin a national network of charging points in Canberra next year, followed by a targeted introduction in Sydney and Melbourne in 2013, covering the other capitals in 2014 and a highway network in 2015.

Other companies including ChargePoint Australia are also looking to create a recharging network to cater for the growing EV fleet.

In addition to a public network - set up within car parks - companies will offer EV drivers in-house recharging points. Their systems will be able to take advantage of off-peak charging and even feed power back into the grid at peak times, giving EV drivers another financial benefit.

That potential financial boost will be helpful to consumers and car companies because the federal government has shown little interest in encouraging motorists into electric cars - despite propping up the local manufacturers with millions in funding.

While it is pushing ahead with its planned carbon tax the government has dropped the Green Car Innovation Fund and the proposed cash-for-clunkers scheme.

This is in contrast to other nations, where governments are offering a variety of incentives to get motorists to ditch petrol power for electric cars. Tax credits to reduce the purchase price, allowing EV drivers to use transit lanes, special EV parking spaces and free public charging infrastructure have all been used to make EVs more appealing to new car buyers. The European Union has even floated the idea of banning all petrol and diesel cars from city centres by 2050.

A spokeswoman for Senator Kim Carr, the Minister for Innovation, Industry, Science and Research, acknowledged the incentives by other countries but questioned the true environmental value of electric cars.

Electric vehicles are often referred to as a zero emissions technology, the uptake of which would reduce carbon emissions, the spokeswoman says. However, potential emissions reductions in Australia need to be viewed with caution because the carbon emissions intensity of Australias electricity production is significantly higher than the world average. Thus a subsidy for electric vehicles in Australia may have limited benefits in terms of reducing emissions.

The Greens deputy leader, Senator Christine Milne, wants to see the government do more to get electric cars onto roads before we fall behind the rest of the world.

Government also has a major role to play in driving renewable energy to support the best possible electric cars and facilitate their roll-out to the broadest possible market as fast as possible, Milne says. China has set an aggressive goal for expanding its electric car market and Australia is once again at risk of falling way behind.

Milne also criticised the governments on-going support of the local manufacturing industry at the expense of electric vehicles.

The limited amount of financial support the government has offered has been targeted at local manufacturing jobs. It has invested less than $10 million on electric vehicle projects while handing over hundreds of millions to Holden, Ford and Toyota under the Green Car Innovation Fund for petrol-powered cars.

Investment in truly innovative car manufacturing in Australia would also see a shift towards electric cars, instead of paying companies to make slightly less inefficient six-cylinder petrol cars, she says.

One car company executive revealed that during a meeting with the government it indicated it was only interested in supporting an electric car if it was made locally. Such a scenario seems some way off, even though Holden admits its new production line in South Australia has been future-proofed to build electric cars.

Before it becomes viable for a manufacturer to build an electric vehicle locally there needs to be more consumer demand, and that may not come for at least another decade. Thats when todays tech-savvy youth of Generations Y and Z become major players in the new car market.

While baby boomers and Gen X might hesitate to move away from traditional petrol and diesel-powered vehicles, the younger generations are hungry to embrace technology.

Over the next decade theyll be the ones getting their licences and reaching the stage in life where they buy a new car, McCrindle says. So this is the emerging market. This is a generation of early adopters of new technology. They want the latest technology and that extends to cars.

RusHydro gives go ahead to 268m marine energy centre

ReCharge News has a look at a giant tidal power development in Russia - RusHydro gives go-ahead to $268m marine-energy centre.

Russian hydropower giant RusHydro is moving ahead with plans to set up an ocean-power turbine research and development (R&D) centre as a springboard for a multi-gigawatt tidal energy project in the White Sea.



The company’s board has approved plans to begin building the Severnaya Innovative Centre of Tidal and Wave Energy on Dolgaya Bay in the Barents Sea, where it will develop turbines to be used in the 8GW Mezenskaya tidal power plant.



A development of this scale could generate 38TWh of electricity a year, claims RusHydro, “comparable to generation of the whole Volga-Kama cascade of hydropower plants”.



The Severnaya centre, which will be run by RusHydros R&D institute, JSC NIIES, is expected to cost RUR7.5bn ($268m) in total to construct. It should open its doors in four years.

Breakthrough in solar efficiency by UNSW team ahead of its time

The SMH has a report on advances in solar cell efficiency at UNSW - Breakthrough in solar efficiency by UNSW team ahead of its time.
Australian scientists have found a way of hugely increasing the efficiency of solar panels while substantially reducing their cost. The University of NSW researchers have come up with improvements in photovoltaic panel design that had not been expected for another decade.

The breakthrough involves using hydrogen atoms to counter defects in silicon cells used in solar panels. As a consequence, poor quality silicon can be made to perform like high quality wafers. The process makes cheap silicon "actually better than the best-quality material people are using at the moment", the head of the universitys photovoltaics centre of excellence, Professor Stuart Wenham, said. Silicon wafers account for more than half the cost of making a solar cell. "By using lower-quality silicon, you can drastically reduce that cost," he said. "Weve been able to figure out what the secret is that enables hydrogen to sometimes work the way people want it to, and sometimes doesnt."

At present, the best commercial solar cells convert between 17 per cent and 19 per cent of the suns energy into electricity. UNSWs technique, patented this year, should produce efficiencies of between 21 per cent and 23 per cent. ...

The price of solar panels has fallen by about 65 per cent in two years, partly due to a huge rise in production in China. Australians have been taking advantage of lower prices, with the number of homes with solar panels exceeding 1 million. The phenomenal growth has caused some casualties in the industry as companies have taken on massive debt to expand supply, then struggled with falling prices in saturated markets. Notable among them is the recent debt default by Suntech Power, once the worlds largest solar-panel maker, founded by former University of NSW researcher Shi Zhengrong.

Panel prices are predicted to fall much further. European producers predict they will be 60 per cent cheaper by 2020. "Based on the technological advances were making, we think thats certainly achievable," Dr Wenham said.

Eight commercial firms have signed up to be a partner in developing the technology to an industrial scale, including Suntech, which continues to operate from its base in the eastern Chinese city of Wuxi and has a research unit in Sydney.

Scottish Government gives go ahead to world’s largest tidal power project

Energy Efficiency News has a post on a tidal power project in Scotland - Scottish Government gives go ahead to world’s largest tidal power project.
The Scottish Government has given the go ahead to what will be the world’s largest tidal stream energy array to date in the Sound of Islay.

The £40 million ScottishPower Renewables development of underwater turbines will have a capacity of 10 MW, generating enough electricity to power around 5000 homes and eight local distilleries and maltings.

“With around a quarter of Europe’s potential tidal energy resource and a tenth of the wave capacity, Scotland’s seas have unrivalled potential to generate green energy, create new, low carbon jobs, and bring billions of pounds of investment,” commented Cabinet Secretary for Finance and Sustainable Growth John Swinney in a statement yesterday.

He said that ScottishPower Renewables, which is owned by Spanish power giant Iberdrola Renovables, will work with the Islay Energy Trust to maximise local social and economic benefits.

Local Scottish businesses are also set to benefit, with £4 million in contracts to make the turbines, with a test prototype being manufactured at Burntisland Fabrication’s (BiFab) facility in Arnish.

BiFab has a £2 million contract to build turbines for the ten 1 MW HS1000 devices to be used in the Islay project, which are being developed by Hammerfest Strøm, a joint venture between Scottish Power Renewables and Norwegian energy companies.

A prototype of the HS1000 device has been generating electricity in Norwegian waters for six years and the company is currently constructing the first commercial-scale device for testing in Scottish waters off Orkney later in the year.

Scotland is one of the leaders in tidal development, with world’s first commercial wave and tidal leasing round already underway for the Pentland Firth, which could ultimately produce some 1600 MW of marine energy.

“[The] announcement moves the whole marine renewables industry forward in Scotland and the UK,” says Keith Anderson, chief executive of ScottishPower Renewables. “The understanding we develop from Islay will be essential in delivering the larger planned projects in the Pentland Firth.”

The testing of the HS1000 later this year in Orkney will determine the rollout of the devices in Islay, but ScottishPower Renewables expects to start work on the project next year and start installation between 2013 and 2015.

New Zealand is also looking to develop some large scale tidal power - Kaipara tide turbine plan gets Govt green light.
A $600 million proposal to create New Zealands first tide-driven power station in the Kaipara Harbour has been approved by Government despite concerns it could kill off fish stocks and threaten critically endangered Maui dolphin.

Conservation Minister Kate Wilkinson this morning signed off the staged installation of 200 tidal turbines near the mouth of the harbour by Crest Energy.

Local fisherman, Te Uri O Hau Settlement Trust and the Department of Conservation had opposed the plan, arguing it could reduce west coast snapper stocks, threaten the environment of the pristine harbour and impact Maui dolphin numbers.

But Ms Wilkinson backed an Environment Court ruling approving the station on the condition it started with only three turbines and conducted two years of environmental monitoring.

If fully implemented, it is estimated the development could generate enough electricity to power the area from Aucklands North Shore to Cape Reinga, she said.
