Samenvatting:
Hydrogen is likely to play an important role in future renewable energysupply. Storage and transport of hydrogen can take place in its free form, or chemically bound e.g. as methane. An important advantage of the indirect use of hydrogen as energy carrier is, that in future renewable energy supply, parts of the existing large-scale energy infrastructure could still be used. Production of Substitute Natural Gas (SNG) by biomass hydrogasification has been assessed as a process for chemical storage of hydrogen. Thermodynamic analysis has shown the feasibility of this process. The product gas of the process has a quality quite comparable tot he quality of the Dutch natural gas and might potentially be transported through the existing gas net without any adjustments. In the long term, hydrogen from water electrolysis will become available for the energy market, and can be used within this process. In the short term, the required hydrogen may be obtained from hydrogen-rich gases available as by-product from industrial processes. Results of experimental and modelling work, as well as the economic and ecological feasibility of the process, application potential in the Netherlands, and plans for future development are presented.
