Thermochemical processes for hydrogen production. Progress report, August 1, 1977--February 28, 1978
- comp.
The Los Alamos Scientific Laboratory's (LASL) program to study thermochemical processes for hydrogen production from water consists of three major areas: cycle evaluation and developing new methodology to evaluate thermochemical cycles. The Thermochemical Cycle Evaluation Panel is being assisted to perform engineering and economic analyses of selected cycles. Analytical and experimental studies are made in direct support of the two cycles selected for early development and evaluation. The cycles are the hybrid sulfuric acid cycle (Westinghouse) and the sulfuric acid-iodine cycle (General Atomic (GA)). One study is directed at heat penalties associated with drying sulfuric acid solutions, a significant problem in both cycles. Oue analysis indicates that the precipitation of an insoluble, anhydrous metal sulfate could significantly reduce such heat penalties. Experimental studies are being made of the precipitation and decomposition of bismuth sulfate, which appears to be a promising candidate. Use of fusion energy sources from the production of synthetic fuels (hydrogen) is being evaluated. Thermochemical cycle input data are being provided in the form of cycle thermal requirements to design study groups at each laboratory being supported by DOE Office of Fusion Energy. Initially, a hybrid sulfuric acid cycle with a bismuth sulfate decomposition step at high temperature is being explored.
