摘要

Hydrogen is usually presented as a promising energy carrier that has a major role to play in low carbon mobility, through the use of fuel cells. However, such a market is not expected in the short term. In the meantime, hydrogen may also contribute to reduce carbon emissions in diverse sectors: oil refining, low carbon mobility through the industrial deployment of advanced biofuels, natural gas consumption, and methanol production. According to the targeted market, objective costs are rather different; and so is the reachable mitigated CO₂ amount.

This paper assesses the dynamics of these markets' attractiveness, in order to provide target costs for CO₂-free hydrogen production. The potential of the markets of hydrogen as a fuel and hydrogen for the biomass-to-liquid production is highlighted, as they could represent significant volumes by 2050, as well as interesting perspectives for CO₂ emission reduction. However the targets are very sensitive to the CO₂ price, thus highlighting the requirement for economic instruments in order to facilitate the penetration of such technologies. Hydrogen is then highlighted as a key player of the energy system in the years to come, as the connection of the energy and mobility sectors.
