ABSTRACT
Hydrogen could become the carrier for all energy-based activities. The distribution of hydrogen gas through pipelines is quite feasible in the same manner as earth gas is distributed over wide distances. This type of distribution from central solar power plants can compete with the distribution of electricity either through cables or high-voltage lines. Local transformation of hydrogen into electricity and with high efficiency is an important research area in the future. Main applications of fuel cells are seen today in industrial cogeneration systems to replace gas-turbine-combined cycle and utility power plus boiler steam in the Chlor-Alkali industry where electrical power is used in combination with process heat. The waste heat generated is conducted to a steam turbine with generator to make electric power for the electrolytic tanks while process steam is used for tank heat. The utilization of fuel cells replaces the turbine plus generator as the gas used generates sufficient heat in the electrolyte during dissociation.
