The switch from gray to green hydrogen isn’t just hot air.
Green power from sustainably produced hydrogen will likely play a big role in the energy transition. Emissions from hydrogen fuel cells are clean, but the production of hydrogen itself has a ways to go before it’s environmentally friendly. Most hydrogen these days is “gray hydrogen,” which is made using fossil fuels. Then there’s “green hydrogen,” made with renewably produced electricity that’s used to separate water into hydrogen and oxygen using a tool called an electrolyzer.
