A TECHNO-ECONOMIC ANALYSIS OF DECENTRALIZED ELECTROLYTIC HYDROGEN PRODUCTION FOR FUEL CELL VEHICLES


Fueling is a central issue in the development of fuel cell systems, especially for transportation applications. Which fuel(s) will be used to provide the necessary hydrogen and what kind of production/distribution infrastructure will be required are key questions for the large-scale market penetration of fuel cell vehicles (FCVs). Methanol, gasoline and hydrogen are currently the three most seriously considered fuel options. Primarily because of economic considerations, these energy currencies would all be largely produced from fossil fuel sources in the near future. One problem in using fossil fuel sources as a feedstock is their associated emissions, in particular greenhouse gases (GHG). Hydrogen generated from any fossil fuel, either onboard vehicles or at a stationary plant, invariably releases carbon-containing byproducts, generally in the form of CO_2. Even hydrogen produced from stationary steam reforming of natural gas, considered as the economically feasible option with the most significant reductions in GHG emissions, still emits 30-60% of the GHG emissions from a 30 mpg (7.8 L/100 km) gasoline internal combustion engine (ICE) vehicle (for an FCV with fuel economy in the 66-84 mpg gasoline equivalent range). Hydrogen from water electrolysis constitutes an inherently more flexible option with respect to the energy input required and the associated GHG emissions. Electrolysis can make use of the electrical and water infrastructure already available in many areas. It also provides access to nuclear and renewable energy sources, which have very low GHG emissions. Moreover, an interesting synergy between similar aspects of water electrolysis and fuel cell technologies could have a noticeable impact on the development and cost of the electrolytic fueling option. Electrolyzers can be scaled-down relatively easily compared to other options, which may be an important advantage for the smooth market penetration of FCVs. Accordingly, some electrolyzer companies have adopted a product development strategy that emphasizes the decentralized production of electrolytic hydrogen for the future FCV market. This paper presents some elements of a study currently underway to assess the techno-economic prospects of decentralized electrolytic hydrogen production for FCVs.......
