For a concentration of. 70 wt-% of H2O2 in water (0.89 kg H2O2 L 1), this is equivalent to 3.1 MJ per litre of 70 wt-% H2O2. By comparison, a tank of H2. 1 (g) at 70 MPa at room temperature can produce 6.8 MJ L (theoretical) when operating in a fuel cell. However, an esti-mated 20 % of that energy is used to compress the H2(g) in the first ...

Based on the reviewed literature, regardless of the acronyms/names used, the mixture is a fuel blend consisting of 3–80% hydrogen in CH 4 or NG. Although in theory the two (hydrogen and NG) can be mixed in any proportion, when blending hydrogen with NG, the differences in their properties should be considered.
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.
