The only current alternative mature process is electrolysis, and almost all studies on hydrogen rely on electrolysis features and economics. Hydrogen from electrolysis cost relies itself mainly on electricity cost and status (renewable or not).
Hydrogen produced by HYNOCA relies on biomass, and the energy efficiency is higher than electrolysis, with an energetical cost 3 to 8 times lower than electricity. The resulting hydrogen cost at the distribution spot is between 30% to 70% cheaper than the cost of hydrogen produced by electrolysis depending of the applications. This is a huge difference radically changing the economics of renewable hydrogen.
Furthermore, not only the renewable status of hydrogen will ever be questionable, but hydrogen from Hynoca is also strongly carbon negative. At best, hydrogen from electrolysis can claim to be carbon neutral.
At last, in most areas in the world, there is no obstacle to produce hydrogen on the distribution selected site, as biomasses are always available at any time of the year, if need be 8400 hours per year. Electricity from renewable energies is generally produced only approximately 2000 hours per year (vs nominal capacity), and there can be long periods without wind and/or sun.
