Renewable hydrogen can be the ticket to greener transportation, but the costs will have to come down first. The power industry and researchers are conducting trials in an industrial power-to-gas plant in the southern German town of Grenzach-Wyhlen to investigate ways of cutting costs. As of April 2020, the megawatt plant had been on line for four months and running reliably. An on-site research electrolyzer is also operating very successfully. The Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) is coordinating this project. Energiedienst AG, a power company, operates the commercial plant.
