Strategies for emission control on biogas upgrading plants

25 Oct, 2023 - 25 Oct, 2023
Location: Niederwil, Switzerland
Task 37RegularIEA Bioenergy

Workshop organised by Task 37, in collaboration with Biomasse Suisse, Zurich University of applied Sciences (ZHAW), Association of the Swiss Gas Industry, Research Project consortium EMMINA.

The workshop will take place at 9:30 -12:30 CEST, at the Restaurant Gnadenthal, Reusspark 10 in 5524 Niederwil, Switzerland,  and will also be available online.

The upgrading process of biogas to Biomethane results in a gas stream containing (bio-) methane and a second gas stream containing the CO2 and an unwanted part of the biomethane, called methane slip. This CO2 rich gas stream either directly emitted to the atmosphere or its content of methane is oxidised before the release into the atmosphere, according to the applicable regulations. National regulations on the handling of the methane slip differ substantially in EU countries, France has recently changed the thresholds, in Switzerland new regulations are discussed. The presentations address the options for the reduction of the emissions and put the options for emission reduction into a context with GHG balances and national situation in Switzerland and France.
