The funding follows three previous awards to the Appalachian, California and Pacific Northwest hydrogen hubs.
HyVelocity’s Gulf Coast hydrogen hub will receive up to $1.2 billion in federal cost share, with up to $1 billion heading for MachH2’s Midwest hydrogen hub.
The Gulf Coast hub plans to leverage the region’s renewable energy resources as well as its natural gas supply, producing hydrogen both via electrolysis and from natural gas with carbon capture and storage (CCS).
The Midwest hub is in a key US industrial and transport corridor. It also plans to use both electrolysis powered by renewable energy and gas with CCS to serve customers in the steel and glass, manufacturing, power generation, refining and heavy-duty transport sectors across Illinois, Indiana, Iowa and Michigan.
As part of a larger $8 billion hydrogen hub programme, the H2Hubs programme aims to “create a national network of clean hydrogen producers, consumers and connective infrastructure while supporting the production, storage, delivery and end-use of clean hydrogen”.
Seven hubs will collectively produce millions of tonnes of hydrogen annually. The final two projects are still in negotiations over an award. They are Heartland Hydrogen and Mid-Atlantic Clean Hydrogen Hub.
The DOE’s Office of Clean Energy Demonstrations manages the H2Hubs programme and will oversee the projects selected.
