Danielle Ramelli reveals how Watt Fuel Cell is paving the way for a H2-powered future. As a core participant in the ARCH2 Hydrogen Hub in West Virginia, Watt has successfully tested its microtubular solid oxide fuel cells to operate with up to 20% H2 blended into natural gas lines—with scalable potential for higher blends. This innovation positions Watt as a critical player in building resilient, low-emissions distributed energy systems for homes, remote sites, and beyond.
