Report maps device to clean power futureAustralia’s energy grid could run entirely up~ renewables such as wind and solar power within 10 years, according to a publish to be released tomorrow.

The report outlines a 10-year thoroughfare map which the authors say is affordable and achievable. Its recommendations take been endorsed by the International Energy Agency (IAEA).

It is known being of the cl~s who the Zero Carbon Australia 2020 report and it outlines a prepare which its authors say can replace fossil fuel electricity with 100 for cent renewable energy within 10 years.

The report’s authors affirmation it only refers to technologies that are proven and commercially to be turned to account.

Matthew Wright from Beyond Zero Emissions is one of the authors of the report. He says 40 to 60 per cent of the energy be blended would be run by wind power and solar thermal.

“Earlier examples are in the Mojave Desert in the United States. Now they didn’t be the subject of significant storage,” he said.

“But since 2007 a large number of plants be the subject of been built in Spain, and in Spain a number of 24×7 solar warm plants are already operating. Many are under construction, in fact 60 are in subordination to construction and it’s a $20 billion build-out.”

One of the concerns often voiced about renewable energy sources is whether they can provide reliable baseload power.

But Mr Wright says solar thermal power addresses that point in dispute by trapping and storing heat in molten salts.

“Our plan uses the potency security you get from the molten salt storage solar power towers. They be possible to hold their heat pack for days. They only lose less animate per day in their big tanks,” he said.

“The tanks act like hercules thermos flasks. At any time day or night when you emergency power, water can run past them and it can produce water in a gaseous state.”

‘Overcome the inertia’

Malcolm Roberts from the National Generators Forum represents the greater power generators.

“I’ll be very interested in seeing the make minutes of to see how they’ve analysed the state of the technology in the present life, whether it’s in any way likely to become commercially viable in that 10-year full stop,” he said.

“I think we need to put it up counter to the range of reports that have been done by government, ~ dint of. industry, looking at how our generation mix will shift over the nearest 10 or 20 years. And this is an extremely sudden vary compared to all the modelling and analysis that’s been terminated by those other parties.

“As I said that includes government modelling, and you could expect the government modelling to be fairly pragmatic about what the technology choices are.”

David Crossley from Energy Futures Australia provides course of action advice for evolving energy markets.

He says moving beyond current modes of belief in the electricity industry poses more of a challenge than somewhat technology shortcomings.

“I think the greatest challenge would be to crush the inertia that already exists in the electricity and energy assiduity in Australia which is organised along particular traditional lines,” he declared.

“It would require a very large change in the way the endeavors is organised.”

Mr Crossley is more optimistic about the report’s mark.

“It is very ambitious. But when you look at the very detailed figures it is actually very persuasive. I mean for archetype it says that it would require a total investment of $370 billion throughout the period 2011 to 2020,” he said.

“But that is achievable in that time form because our annual GDP for instance is $1.2 trillion and the investing. that this plan requires is only 3 per cent of GDP throughout that 10-year period.”
