Analysis of Thermochemical Water-Splitting Cycles
The Institute of Gas Technology (IGT), under the sponsorship of the American Gas Association (A.G.A.), is conducting a research program, now in its third year, to derive, evaluate, and experimentally test closed-cycle chemical reaction sequences for splitting water into hydrogen and oxygen. This paper presents a brief description of the IGT program and an analysis technique for evaluating water-splitting cycles when heat is the primary energy source. The treatment is applied to four cycles, and efficiency comparisons with electrolysis are made.
