Presented at: 12th European Conference and Technology Exhibition on Biomass for Energy, Industry and Climate Protection, Amsterdam, The Netherlands, 17-21 juni 2002.
Abstract:
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.
