<p>PROBLEM TO BE SOLVED: To provide a method for producing hydrogen or the like from carbon resources using supercritical or subcritical water that does not require: a structure to bear high temperature and pressure for creating a supercritical or subcritical state of water; energy for elevating water of an ordinary temperature and pressure to the supercritical or subcritical state and maintaining the high temperature and pressure state during chemical reaction; and disposal of by-product carbon dioxide.SOLUTION: A carbon raw material mis supplied through a raw material feed pipe 5 to hot water HW at a supercritical or subcritical state that blows out of hot water blowing holes in the deep sea to produce hydrogen Hand recover the produced hydrogen Hthrough a hydrogen recovering cylinder 8 using buoyancy of the hydrogen Hagainst sea water. Carbon dioxide COgenerated as a by-product liquefies and stays on the sea bottom or drifts in the sea.</p> |
