Saw this from the University of the Basque Country in Spain: Methanol as an alternative
Most current research is focused on hydrogen cells the biggest advantage of which is that they do not generate contaminant gases, except water vapour as the only waste product. However, hydrogen is very expensive, both in producing it and in distributing it using traditional overland transport methods. Moreover, its energy density is less than that of methanol, meaning that, in order to obtain the same energy from a similar amount of fuel, the hydrogen has to be kept and stored under conditions of very high pressure (more than 800 bars). This is why hydrogen is dangerous, and even more so when stored in vehicles travelling at high speed a small crack in the storage container could have fatal consequences. These and other reasons mean that methanol (a type of alcohol derived from methane gas) is a good option for charging fuel cells. ====== I'm surprised scientific work in Europe is still being done using the "bar" instead of the "pascal".
