Seven proposals for regional clean hydrogen hubs have been selected to receive up to $7 billion in funding, the Biden administration said October 13. The hubs are intended to accelerate the commercial-scale deployment of low-cost clean hydrogen. The funding was included as part of 2021’s Infrastructure Investment and Jobs Act, better known as the Bipartisan Infrastructure Law.
Clean hydrogen can be produced by running water through nuclear- or renewables-powered electrolyzers, yielding hydrogen and oxygen. It can also be produced by running natural gas through steam methane reformers and auto-thermal reformers, then capturing and sequestering most of the carbon dioxide (CO2) emitted. The DOE defines a clean hydrogen hub (see schematic below) as a network of clean hydrogen producers, potential consumers and connective infrastructure located in close proximity.
