Kansen voor Groen Gas

Published 2011 / 04
Summary - Study to determine the potential for green gas with consideration for possible competition for other end uses. - Written in parallel with another CE Delft report ?Goed gebruik van Biomassa?. - Government policy and available subsidies play a key role in determining the end uses of biomass. Currently transport and electricity production require a minimum share of fuel/electricity production from biomass of implying that other end uses (such as local heat production or for chemical uses) have trouble competing for resources. - Studies however have shown that a combination of end uses the most efficient is. This would however require that all end uses be equally stimulated. - For wet biomass the gasification to biogas is currently the preferred option with little competition. For dry biomass there are a lot of alternatives. - The potential for biomass is 144 PJ in 2020, equal to 5% of the energy demand in the Netherlands. The potential for biogas is 30-48PJ, equivalent to 1-1,5 billion Nm3 natural gas. - There is a large potential for fermentation of manure. When combined with other rest products the potential for biogas production increases, but so do the costs. - Fermentation could become significantly more attractive if the regulations concerning the use of the digestate as fertilizer are eased. - The potential for gasification of biomass is strongly dependent on competition with other end uses and government policy.
