The hydrogen storage density is high, and it is convenient for storage, transportation, and maintenance with high safety, and can be used repeatedly. The hydrogen storage density is low, and compressing it requires a lot of energy, which poses a high safety risk due to high pressure.
The production of hydrogen from biomass needs additional focus on the preparation and logistics of the feed, and such production will probably only be economical at a larger scale. Photo-electrolysis is at an early stage of development, and material costs and practical issues have yet to be solved. Published January 2006. Licence CC BY 4.0.
