MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. Because VREs such as solar and wind power produce electricity only when the sun shines and the wind blows, they need back up from other energy sources, especially during seasons of high electric demand. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly.
