Australia’s solar heliostat technology will be used for concentrating solar thermal (CST) electricity generation in China.
CSIRO has announced a partnership with Chinese company Thermal Focus, following China’s announcement to produce 1.4 GW of CST by 2018, and 5 GW by 2020. This will double the world’s installed CST plants.
The relationship enables Thermal Focus to manufacture, market, sell and install CSIRO’s patented low cost heliostats, field control software and design software in China, with a shared revenue stream back to Australia to fund further climate mitigation research.
CSIRO CEO, Dr Larry Marshall said the partnership takes Australia's clean energy technology to a global stage.
Solar thermal technology uses a field of computer-controlled mirrors (heliostats) that accurately reflect and concentrate sunlight onto a receiver on top of a tower.
The concentrated sunlight may then be used to heat and store hot molten salt, which can generate superheated steam to drive a turbine for electricity generation.
An advantage of this system is the very low cost of storing thermal energy, giving CST technology great potential for medium to large-scale solar power, even when the sun isn’t shining.
A heliostat field can represent up to 40 per cent of the total plant cost so low cost, high precision heliostats are a crucial component.
CSIRO’s unique design features smaller than conventional heliostats, and uses an advanced control system to get high performance from a cost-effective design.
CSIRO’s software optimises the configuration of the heliostats prior to construction and manages each heliostat to ensure the optimum amount of reflected heat is focused on the receiver, maximising the amount of power that can be produced.
The licensing agreement with Thermal Focus follows CSIRO’s successful international solar thermal partnerships with Japan’s Mitsubishi Hitachi Power Systems, and the Cyprus Institute and Heliostat SA in Australia.
Wei Zhu from Thermal Focus said the partnership will help commercialise this emerging technology on a larger scale.
Details of the licensing agreement with China’s Thermal Focus will be announced later today at the Asia-Pacific Solar Research Conference at the Australian National University.
