Thermochemical processes for hydrogen production. Progress report, October 1, 1979-September 30, 1980
- comp.
Thermochemical cycles for hydrogen production have been investigated at the Los Alamos National Laboratory since the early 1970s. The work consists of experimental and engineering research to define cycles that can be coupled feasibly to high-temperature heat sources for water-splitting to produce hydrogen and oxygen. Process development is sponsored by the Department of Energy, Division of Energy Storage System (STOR). In recent months, our efforts were directed toward improving the design and operation of our 1-in-diam laboratory-scale quartz rotary kiln. Our results from the decomposition of bismuth oxysulfate in the kiln have been shown the technical feasibility of solid sulfate decomposition in a flow mode with recycled feed in residence times less than 2 min. Other work included (1) engineering studies that compared the published estimates of capital costs and process efficiencies for hydrogen production by thermochemical means and by electrolysis, (2) review of two thermochemical cycles for hydrogen production, and (3) coordination of US contributions to the annual International Energy Agency Technical Workshop on Thermochemical Processes.
