World first: Australian solar plant has generated “supercritical” steam that rivals fossil fuels’

A CSIRO test plant in Australia has broken a world record and proved solar power could efficiently replace fossil fuels.

 

A solar thermal test plant in Newcastle, Australia, has generated “supercritical” steam at a pressure of 23.5 mpa (3400 psi) and 570°C (1,058°F). CSIRO is claiming it as a world record, and it’s a HUGE step for solar thermal energy.

“It’s like breaking the sound barrier; this step change proves solar has the potential to compete with the peak performance capabilities of fossil fuel sources,” Dr Alex Wonhas, CSIRO’s Energy Director, said.

 

The Energy Centre uses a field of more than 600 mirrors (known as heliostats) which are all directed at two towers housing solar receivers and turbines, Gizmag reports.

 

This supercritical steam is used to drive the world’s most advanced power plant turbines, but previously it’s only been possible to produce it by burning fossil fuels such as coal or gas.

 

“Instead of relying on burning fossil fuels to produce supercritical steam, this breakthrough demonstrates that the power plants of the future could instead be using the free, zero emission energy of the sun to achieve the same result,” Dr Wonhas explained.

 

Currently, commercial solar thermal or concentrating solar power power plants only operate a “subcritical” levels, using less pressurised steam. This means that they’ve never been able to match the output or efficiency of the world’s best fossil fuel power plants – until now.

 

The commercial development of this technology is still a fair way off, but this is an important first step towards a more sustainable future.

About tanialibraryquest

I am a drama/ history teacher and have just started a Masters of Education Teacher Librarian. I have been involved extensively in the arts, mostly in dance and theatre. I have worked in community theatre through federal arts funded projects and also worked with Ausdance National at National Youth Dance Festivals. I have worked in schools as an "outside professional", and decided to complete and Grad Dip Ed. I was very keen to work in drama in schools but have since gained a number of blocks as teacher librarian. I enjoy the dynamic nature of the work, team teaching, collaborating, management and developing relationships with students who access the library. I have done some renovating and re-organising of teaching areas. I am having a crash course in Oasis library catalogue and also technology! Looking forward to the masters and all it has to offer!
