Comparison of the renewable transportation fuels, liquid hydrogen and methanol. With gasoline-energetic and economic aspects

摘要

In this paper, the renewable energy vectors liquid hydrogen (LH_2) and methanol generated for atmo- spheric CO_2 are compared with the conventional crude oil-gasoline system. Both renewable concepts, liquid hydrogen and methanol, lead to a drastic CO_2 reduction compared to the fossil-based system. The comparison between the LH_2 and methanol vector for the transport sector shows nearly the same fuel cost and energy efficiency but strong infrastructure advantages for methanol.
