BioMil and Renewtec have together conducted the project “Small scale gasification” (in Swedish). Within the framework of the project the biomethane production cost based on gasification and methanation of woody biomass has been calculated for two plants with a capacity of 5.6 MWth and 33 MWth and with and without district heating integration.
The study shows a production cost in the range of 6.40-12.20 SEK/Nm3 biomethane (approx. 70-130 eurocent) depending on the investment support of the Swedish Energy Agency, choice of interest rate, fuel cost and if the excess heat can be utilized or not. Additional cost reduction is possible if the separated carbon dioxide can be used, e.g. as carbon dioxide enrichment in greenhouses.
The project has been financed by Region Skåne, Region Halland, AB Gas & Värmeteknik, AGA Gas AB, BioMil AB, DGC, E.ON Gasification Development AB, Highterm Research AB, Lunds Universitet, NSR AB, O2 Bio AB, Purac Puregas AB och Renewtec AB.
