Proved competitiveness of small scale bioSNG technology
Small scale bioSNG technology based on allothermal gasification is able to compete with large scale bioSNG technology based on pressurised oxygen-blown gasification. This technology has proved competitive in terms of GHG emissions, primary energy needs and conversion efficiency without high production costs.
The results are part of the LignoSys research project, which has investigated the performance of three small scale (~10 MWth) thermochemical conversion routes for lignocellulosic feedstock to biomethane. The three thermochemical options were:
- Indirect gasification through the Heatpipe Reformer (HPR)
- PyroCatalytic Hydrogenation (PCH)
- Indirect gasification through the WoodRoll® process
The final report with the results has been published as Renewtec Report 008:2018 (DOI: 10.13140/RG.2.2.32372.81280). The system study was conducted by Lund University and the project was coordinated by Renewable Energy Technology International AB (Renewtec AB). The project was financed by the Swedish Energy Agency and ten partners from six countries, including European Biogas Association.
