Abstract:

Natural gas is a popular fuel for obvious reasons. Substitute Natural Gas (SNG) resembles natural gas, but can be made from a renewable source: biomass. Both in Switzerland/Austria and in the Netherlands, technology is developed to produce BioSNG. Although similar on certain points such as using indirect gasification and tar scrubbing technology, both concepts are also essentially different. The differences have been quantified to be 6%absolute on energy efficiency from biomass to BioSNG: 64% for the Swiss/Austrian and 70% for the Dutch concept. The main reason for the difference originates from the necessity to produce only little tar during gasification in the Swiss/Austrian concept. The Dutch developments aim at large­scale plants of at least 100 MW for cost reasons, but also to enable the CO2 co­product to be stored and produce power as a co­product. The Swiss/Austrian developments seem to aim at typically 50 MW plants for the supply of both SNG and heat at a high overall efficiency. Calculations however, indicate that the process leaves only little heat to export unless further decrease of the energy efficiency from biomass to BioSNG is accepted.
