PRIMARY ENERGY-SOURCES FOR HYDROGEN-PRODUCTION

The cost of hydrogen from water electrolysis is estimated, assuming th at the electricity was produced from solar, hydro-, fossil, or nuclear power. The costs for hydrogen end-use in the sectors of power generat ion, heat and transportation are calculated, based on a state-of-the-a rt technology and a more advanced technology expected to represent the state by the year 2010. The cost of hydrogen utilization (without ene rgy taxes) is higher than the current price of fossil fuels (including taxes). Without restrictions imposed on fossil fuel consumption, hydr ogen will not gain a significant market share in either of the cases d iscussed.
