New Concentrated Solar Thermal Water Splitting Technique Produces Clean Hydrogen Fuel

The CU-Boulder team has devised a solar-thermal system in which sunlight could be concentrated by a vast array of mirrors onto a single point atop a central tower up to several hundred feet tall. The tower would gather heat generated by the mirror system to roughly 2,500 degrees Fahrenheit (1,350 Celsius), then deliver it into a reactor containing chemical compounds known as metal oxides, said CU-Boulder Professor Alan Weimer, research group leader.

Global Renewable Energy Growth Expected to Be Strong to 2030

Bloomberg New Energy Finance show that annual investment in new renewable power capacity is set to rise by anywhere from two and a half times to more than four and a half times between now and 2030. The likeliest scenario implies a jump of 230%, to $630bn per year by 2030, driven by further improvements in the cost-competitiveness of wind and solar technologies relative to fossil fuel alternatives, as well as an increase in the roll-out of non-intermittent clean energy sources like hydro, geothermal and biomass.
