Stable photoelectrochemical water splitting for solar fuels generation

by |January 13th, 2017

The ability to efficiently and economically store variable solar energy would be a major step towards meeting growing global energy demands. This can be accomplished by converting excess solar energy into chemical energy, or “solar fuels”, a concept which has the potential to compensate for solar energy intermittency and also provide a carbon neutral transportation… read more

Underground injections turn carbon dioxide to stone

by |June 15th, 2016

Researchers working in Iceland say they have discovered a new way to trap the greenhouse gas carbon dioxide (CO2) deep underground: by changing it into rock. Results published this week in Science show that injecting CO2 into volcanic rocks triggers a reaction that rapidly forms new carbonate minerals—potentially locking up the gas forever.
