32.5 Conclusion
In this study, to promote the application of the HRES, a novel system based on the integration of water electrolysis and supercritical water gasification of wet biomass feedstock was proposed. The results of the detailed techno-economic analysis revealed
that the annual electricity generated by the proposed HRES system could sufficiently
meet the load requirements in the selected household area in Shinchi-machi. As indicated by results, the total annual electricity generated by the proposed HRES is about
4.73MWh with a total annual hydrogen generation of 63.4 kg, using the annual wet
biomass consumption of 122.7 kg.
