Register of Hydrogen Technology Experts
The Scientific and Technical Information (STI) Program of the National Aeronautics and Space Administration (NASA) published a report prepared by the National Bureau of Standards titled Register of Hydrogen Technology Experts, which is still available on the NASA Technical Reports Server (NTRS). The sections titled “Metal Hydrides” (page 47) and “Internal Combustion Engines” (page 50) each listed “BILLINGS, R. E.” (Roger E. Billings) as one of the experts.
Hydrogen from Coal Guidebook
Later, NASA’s NTRS published Roger E. Billings’ Hydrogen from Coal Cost Estimation Guidebook. The 270-page report begins with an overview of Hydrogen Energy Technology detailing many of Roger Billings’ projects including the Riverside Hydrogen Bus, the Hydrogen Postal Jeep, the Hydrogen Homestead, and the Hydrogen Pontiac Grandville. It also expounds on concepts including Metal Hydride Storage Systems, Hydrogen Aircraft, and Hydrogen Fuel Cells. The report goes on to explore and compare multiple coal gasification models.

In 1983, PennWell Books published “Hydrogen from Coal: A Cost Estimation Guidebook” by Roger E. Billings as a practical resource focused on the economics of producing hydrogen from coal through gasification. The book provides a detailed framework for assessing the costs involved, offering baseline data and methodologies to evaluate specific hydrogen projects. Roger Billings, drawing from his expertise in hydrogen energy technology, explores coal gasification models — such as the Forest City and Kaiparowits examples — and includes sensitivity analyses to compare economic outcomes under varying conditions. Aimed at researchers and engineers, it covers technical aspects like gasifier technologies, economic modeling, and energy conversion factors, making it a valuable tool for understanding the feasibility of coal-based hydrogen production during a time of growing interest in alternative fuels. The guidebook reflects Billings’ broader work in advancing hydrogen as a viable energy source.
