The implications of using hydrocarbon fuels to generate electricity for hydrogen fuel powered automobiles on electrical capital, hydrocarbon consumption, and anthropogenic emissions

► On site steam reforming results in the least disruption to the electrical generation. ► On site steam reforming results in the least greenhouse gas emissions. ► Reforming accelerates the consumption of natural gas stocks. ► Electrolysis requires large capital investments in generation capacity. ► Electrolysis increases anthropogenic greenhouse emissions.
