By storing hydrogen in an oil-based slurry with powdered magnesium hydride, inexpensive and safe hydrogen storage can be realized. This paper describes the characteristics and benefits of cycling hydrogen in and out of magnesium hydride slurry. An application of magnesium hydride slurry in a baseload wind power system is discussed. It concludes that a 150 MW baseload wind power system can produce an internal rate of return (IRR) of 10% with an electric price of $0.088/kWh. The costs and performance characteristics of this power plant are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
