Removing non-CO2 greenhouse gas emissions to support ambitious climate transitions

Project description

What to do with greenhouse gases like methane and nitrous oxide

In addition to CO2, anthropogenic emissions are also made up of non-CO2 greenhouse gases, which are just as harmful to the climate and no less difficult to tackle. Mitigating these gases can significantly accelerate the transition towards a net-zero greenhouse gas EU economy by 2050 and achieve sustainable negative emissions thereafter. The EU-funded REPAIR project will develop two breakthrough technologies to remove non-CO2 gases like methane and nitrous oxide from the atmosphere. One will capture and convert. The other involves direct catalytic conversion. Both solutions will be evaluated in terms of impact in the agricultural and farming sector. A successful outcome will help the EU achieve climate neutrality and create socio-economic impact.

Objective

"Non-CO2 greenhouse gases are responsible for 28% of total anthropogenic emissions, of which CH4 (16%) and N2O (6%) are major contributors. These gases are hard to abate due to their diverse and inherently distributed sources (with concentration <1%-vol), for example the agricultural sector (livestock and farming), which is the main source of anthropogenic CH4 emissions. Moreover, their very low concentrations in the atmosphere (ppb or ppm level) make the recovery particularly challenging. However, mitigating these gases can significantly accelerate the transition towards a net-zero greenhouse gas EU economy by 2050, and achieve sustainable negative emissions thereafter. In this context, REPAIR will develop first-of-its kind technological proof of concept to remove non-CO2 gases like CH4 and N2O from diluted sources, including from the atmosphere. Two process routes are proposed: (i) capture, concentration and storage/conversion (ii) direct catalytic conversion. The proposed processes can be easily integrated with direct air capture and storage and/or use of CO2, thereby removing multiple greenhouse gases (CH4, N2O and CO2) in a single system with lower energy and cost. The potential of the technologies developed in the REPAIR project will be evaluated through (i) techno-economic analysis (ii) scenario-based assessment to evaluate impact on climate (iii) impact case studies in agricultural and farming sector. Results will enable making decisions about upscaling of the technology in agricultural farms by 2035 in addition to increasing knowledge about plausibility of removing non-CO2 gases from diluted sources. It will also help the European Commission to make informed decisions about regulations for non-CO2 greenhouse gas emissions from 2030 as indicated in the ""Fit for 55"" plan. The project consortium has expertise and experience to develop emerging and break-through technologies with high potential to achieve climate neutrality and create socio-economic impact."
