Steam iron process, hydrogen by the

The future attractiveness of the coal-based process will depend upon the availability of natural gas or oil at a reasonable cost. If the coal cost rises to 1.50/106 Btu from the 1.00 level, then the cost of natural gas must rise to 3.10/106 Btu for hydrogen by the Steam-Iron Process to compete with reforming if by-product power sells at 4c/kWhr. At 2c/kWhr by-product power, natural gas cost must rise to 4.65/106 Btu for the Steam-Iron Process to be competitive.
