CHEYENNE, Wyo. (AP) — The governors of four Rocky Mountain states say they will cooperate on developing ways to make hydrogen more available and useful as clean-burning fuel for cars, trucks and trains. Colorado, New Mexico, Utah and Wyoming announced Thursday they’ll plan a “hydrogen hub” to be built somewhere in the region. The project will draw from $8 billion in recently approved federal infrastructure funding for four or more such regional hubs in the U.S. The Western Inter-State Hydrogen Hub will have facilities in all four states under plans to be submitted to the U.S. Department of Energy.
