Hydrogen is mainly used for the production of fertilisers, for refinery processes, methanol production as well as steel production. The production of bio-hydrogen from biomass is of interest for several reasons: it delivers green hydrogen from a renewable source for storage, hydrogen for mixing with natural or biogas, and hydrogen for synthesis processes. Today, hydrogen can be realised with efficient electrolysis processes, in which case the cost of power significantly contributes to the cost of hydrogen per kg. The real advantage of bio-hydrogen is the decentralised provision compared to the production based on natural gas as discussed in literature. Small scale conversion units can be located close to villages and cities and supply hydrogen on a demand basis in combination with heat and power production as alternatives. This will drastically lower the costs of infrastructural measures for the new hydrogen economy.
