Solar reactor concentrates light to produce hydrogen fuel




Thermochemical reaction produces hydrogen from water and carbon dioxide.  This process could be commercialized if paired with the carbon emissions from an existing1482-smh_wcc_with_reactor_use-smaller_medium[1] power plant.  …

…   “The researchers designed and built a two-foot-tall prototype reactor that has a quartz window and a cavity that absorbs concentrated sunlight.

The concentrator works like the magnifying glass you used as a kid to focus the sun's rays, says Haile. 

At the heart of the reactor is a cylindrical lining of ceria.

Ceria—a metal oxide that is commonly embedded in the walls of self-cleaning ovens …”   …
