Hydrogen: an accommodating fuel

A controlling influence on hydrogen as an energy vector will be the competitive position of electricity. Development of the distribution infrastructure for hydrogen can be expected to complement the electric system, the two together providing an optimum energy network. Hydrogen will be an accommodating fuel: fossil hydrogen helping, in some markets, to extend the use of fossil fuels as primary energy sources; nonfossil hydrogen later providing an alternative to electricity as an energy carrier for some developing nonfossil resources.
