Two of the seven proposals selected for federal funding to develop clean hydrogen "hubs" have a footprint in Pennsylvania. The state has several key components of hydrogen production already in place, including huge quantities of natural gas that can be processed into hydrogen needed to decarbonize key industries. But harvesting hydrogen from methane without releasing even more greenhouse gases is easier said than done -- and the alternative, water electrolysis, will require a gargantuan buildout of nuclear and renewable energy sources. What will it take to get hydrogen right in PA? Sam Bailey of Clean Air Task Force has answers.
