Adding gas from biomass to the gas grid - SGC

8 CONCLUSIONS AND RECOMMENDATIONSConclusions• The production and upgrading of biomass to biogas, suitable for addition to the gas grid, is aproven technology. Several areas, such as control and analysis systems and cost reduction,need further development.• The production of pipeline quality gas from biomass via thermal processes, combinesessentially two proven technologies: syngas production from biomass and syngas conversion tomethane.• The introduction of biogas into separate town gas grids has been proven to be successful.• Production, upgrading to natural gas quality and addition to the gas grid leads to a very highutilisation rate of energy from biomass.• Taxes form a marketing instrument to promote biogas.• Delivery of biogas off-spec requires a gas quality tracking system and close communicationbetween the upgrading plant and the grid owner.The following roadblocks for introduction of biogas to the gas grid were identified• Missing regulation and legislation of access rights can inhibit biogas introduction.• The biogas production site should be located near a gas pipeline and a widely distributednatural gas grid is recommended.• Electricity production out of biomass is in some countries more profitable than production ofbiogas, due to the existing tax instruments.• The tax instruments are not unified in the EU countries.Recommendations• Standardisation for the quality aspects and access rights within Europe for adding biogas to thegas grid.• A wide band gas quality policy on new gas appliances• Stimulation of demonstration and implementation projects at various scale sizes where anincreased value of biogas and a higher usage rate can be realised.page: 116
