A method and apparatus for use in producing high-pressure hydrogen from natural gas, methanol, ethanol, or other fossil fuel-derived and renewable hydrocarbon resources. The process can produce hydrogen at pressure ranging from 2000 to 12,000 pounds per square inch (psi) using a hydrogen feedstock ( 16, 18 ) high pressure water ( 12, 18 ), and an appropriate catalyst. Following making and heating in preheater ( 14 ), the catalyst reacts with the hydrogen feedstock ( 16, 18 ) and high pressure water ( 12, 18 ) in a catalytic reformer ( 20 ) maintained under desired temperature and pressure conditions. Reformate products exit reformer ( 200 ) and flow into condenser ( 22 ), in which water and a portion of the carbon dioxide product are condensed.
