Splitting Water Offers an Inefficient but Effective Way to Store Energy
Gas power: A Hydrogenics electrolysis system in Falkenhagen, Germany, can absorb two megawatts of excess renewable energy and store it in the form of hydrogen.
Germany, which has come to rely heavily on wind and solar power in recent years, is launching more than 20 demonstration projects that involve storing energy by splitting water into hydrogen gas and oxygen.
The projects could help establish whether electrolysis, as the technology is known, could address one of the biggest looming challenges for renewable energy—its intermittency.
