Calculation of Greenhouse Gas Savings: Switch from Electricity Production to Biomethane. Case Study

Abstract

Greenhouse gases are mainly comprised of carbon dioxide. In 2021, anthropogenic CO2 emissions in the atmosphere have risen to 37.9 Gt, a 60 % increase from the levels observed in 1990. The production of high-value products using CO2 can contribute to decreasing atmospheric CO2 levels and advancing the objectives of the Green Deal. In Latvia, biofuel–biomethane production may also present a viable solution. Diversifying the energy sector, which can benefit the country's economy, is another advantage of this scenario. The study examines the transformation of a Latvian biogas production facility, which shifts towards producing biomethane as its final product. The study also involves the computation of greenhouse gas emission reductions resulting from utilizing biomethane instead of biogas in the network.
