This hybrid workshop on 25 Oct 2023 was organised by IEA Bioenergy Task 37 in conjunction with Biomasse Suisse, Zurich University of Applied Sciences (ZHAW), the Association of the Swiss Gas Industry and the research project consortium EMMINA.
The main topic was emissions from the biogas upgrading process at AD plants. Upgrading produces a biomethane gas stream and a second gas stream containing the CO2 and an unwanted part of the biomethane, called methane slip. This CO2-rich gas stream may be directly emitted to the atmosphere or its methane content can be oxidised before release
The workshop considered the options for reduction of emissions and put the options into context with GHG balances and the national situation in Switzerland and France.
Details of speakers and copies of presentations are available HERE. In-person attendees at the workshop included Dr Mark Walker on behalf of EBNet’s AD WG, with several other WG members present or joining online.
