Japan To Test Datacenter Powered By Reused Hydrogen Fuel Cells

Honda and Mitsubishi are collaborating in a two-year project in Shunan City, Japan, to evaluate the feasibility and environmental benefits of powering a data center with fuel cells taken from electric vehicles. The Register reports: Hydrogen for the fuel cell power station will be provided by a third Japanese company, Tokuyama Corporation, as a byproduct from its salt water electrolysis business, which manufactures about 50,000 tons of sodium hypochlorite each year. The project was proposed by Japan's New Energy and Industrial Technology Development Organization (NEDO), which promotes the research, development and adoption of industrial, energy and environmental technologies. The objective is to consider ways of reducing costs for organizations to install and operate stationary fuel cell systems, which could ultimately contribute to the decarbonization of the electric power supply. No details were disclosed of the kind of datacenter infrastructure that Mitsubishi will operate as part of this project, so it is unknown how much power the fuel cell power station will be required to supply. [...] Hydrogen can be considered a clean fuel because it produces only water as a byproduct when consumed in a fuel cell. But the problem is in sourcing the hydrogen. Much commercially produced hydrogen is extracted from methane gas via an energy-intensive process typically powered by fossil fuels. It is likely that the process Tokuyama uses in its salt water electrolysis is ultimately powered by fossil fuels, but the hydrogen is produced as a byproduct and this is currently just a demonstration project to evaluate the feasibility of integrated hydrogen business models. In addition to verifying the use of fuel cells for primary and backup power sources in datacenters, the project will also look at the potential for grid-balancing applications.
