Newcastle project for new solar energy technology

The main advantage of the technology is that, unlike current solar thermal plants, it can be used in areas with no water, which are often the sunniest places on the planet.

Magic of mirrors, Newcastle Herald, BY MATTHEW KELLY27 Oct, 2010 It is used to power jet engines, now the same principle of converting compressed air into energy will produce enough electricity for up to 200 houses.CSIRO’s energy centre at Mayfield West has become home to the southern hemisphere’s biggest Brayton cycle project, which uses only the sun and air to produce electricity.

The main advantage of the technology is that, unlike current solar thermal plants, it can be used in areas with no water, which are often the sunniest places on the planet.

‘‘It’s well suited to mining and minerals projects that use large amounts of electricity but which are located in very remote parts of Australia,’’ CSIRO energy systems manager James McGregor said.

It is also consistent with the CSIRO’s goal of producing solar-generated electricity at the same cost or cheaper than fossil fuel-generated electricity when the cost of carbon is taken into account.

An array of 450 2.4metre by 1.8metre concave mirrors, called heliostats concentrate the sun’s rays at a 30-metre tower containing a radiation receiver, which produces temperatures of up to 1500 degrees.

The heat then drives a compressed air turbine that can produce 200kilowatts of power, which in the case of the Newcastle pilot project is fed into the grid….
