Finding new ways to store renewable energy
Hydrogen holds tremendous promise as a medium for storing power generated by renewable sources such as wind and solar. But storing hydrogen has traditionally involved very high pressures, or very cold temperatures; methods that lead to cost and safety challenges.
Researchers at Pacific Northwest National Laboratory are testing news ways that would allow them to store hydrogen at normal temperatures and pressures. It involves binding the hydrogen to a chemical medium. And because they’re using a green chemistry approach, the chemicals they’re testing are as benign as baking soda.
