Techno-Economic Study of Generating/Compressing Hydrogen Electrochemically, A...Keith D. Patch
The impending hydrogen economy will utilize hydrogen from a number of sources; most notably reformers and water electrolyzers. In the later case, the primary energy source can be conventional (fossil fuels, hydroelectric, nuclear) or renewable (solar, wind, biomass).
However, regardless of the source of the primary energy or the method of hydrogen production, there is a common requirement that the hydrogen be sufficiently compressed to achieve adequate energy density storage and to allow the rapid transfer of gas from central to local or mobile storage systems. In the case of water electrolyzers, the hydrogen can be directly produced at elevated pressures. Independent of the source of the hydrogen, pressurization can also be accomplished subsequent to its production by the use of mechanical or electrochemical compressors.
While current electrolyzer developments have targeted hydrogen production at pressures of 340 bar and higher, careful attention must be paid to trade-offs between the electrolyzer system capital costs, operating costs, and system reliability. The technical and economic impact of varying scenarios has a profound effect on the overall economics of the hydrogen production and, ultimately, on the economics of the hydrogen economy.
