Hydrogen Supply System for FCV (Fuel Cell Vehicles) from Steel Making Off-gas

Abstract

To supply fuel hydrogen for FCV (fuel cell vehicles) efficiently, cost effectively, and with low carbon dioxide discharge, liquefied hydrogen supply system from steel making off-gas especially COG (Coke Oven Gas) was studied. From the point of view of available supply amount, supply cost, energy efficiency, hydrogen from the steel making process was found to have superiority in comparison with other hydrogen sources and supply systems. As for the storage and transportation of hydrogen from production plant to supply station, compressed hydrogen and liquefied hydrogen was studied. In consequence of that, liquefied hydrogen was found to have superiority.
