Electric power requirement in California for large-scale production of hydrogen fuel

摘要

Substitution of hydrogen for fossil fuels in motor vehicles will require a significant growth of electric energy consumption, especially in high growth rate states such as California. A major concern is the magnitude of the additional eelctric power capcity necessary to build a larg-scale hydrogen fuel industry in California to accommodate the fuel demand of a 30-million vehicle fleet. Electrolysis of water may be the only practical means to produce hydrogen in sufficient quantity without use of fossil fuels for so large a vehicle fleet. A dynamic model was used to estimate the increasing annual electric energy requirement to sustain long-term growth of adequate hydrogen fuel production in two time sequences. The first extrapolates historic data on population, vehicle, and energy statistics from California State agencies to the year 2010 when a fuel-cell engine vehicle industry could begin to expand rapidly.
