CSP could meet a quarter of global energy demands

CSP could meet a quarter of global energy demands
Concentrating solar power (CSP) could provide seven percent of the world's energy by 2030 and up to one-quarter by 2050, a new report has suggested.

According to the study - conducted by Greenpeace International, the European Solar Thermal Electricity Association and IEA SolarPaces - the technology could save millions of tonnes of CO2 emissions and create hundreds of thousands of jobs.

CSP uses mirrors to focus sunrays to temperatures between 400 degrees C and 1,000 degrees C. This heat is used to boil water and produce steam, which subsequently drives electricity-generating turbines.

The study estimated that the global electricity capacity of CSP installations was 436MW at the end of 2008.

Commercial projects currently under construction and planned developments could see this figure rise to over 830GW by 2050 with annual deployments of 41GW, it was forecast.

Claiming that CSP has now "taken off", the researchers said in their third joint project that it has the potential to "establish itself as the third biggest player in the sustainable power generation industry".

Spain is currently the world leader in terms of CSP, with more than 50 solar projects in the pipeline for completion between now and 2015.

Recently it launched Andasol 1 - the largest parabolic trough solar thermal power plant in the world - which uses mirrors to heat synthetic oil to temperatures of up to 400 degrees C.

It will open two more stations in the Grenada desert in 2009 and 2011 respectively.
