NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

About half of the levelized cost of retail station hydrogen can be attributed to hydrogen delivery, compression, and dispensing costs. Department of Energy (DOE) estimates that a dispensed cost of about $7/kg must be achieved to make FCEVs competitive with gasoline internal combustion engine vehicles in early FCEV markets.
