Projektbeschreibung
Was tun mit Treibhausgasen wie Methan und Distickstoffmonoxid?
Anthropogene Emissionen umfassen neben CO2 auch andere Treibhausgase, die für die Umwelt ebenso schädlich und gleichermaßen schwer in den Griff zu bekommen sind. Die Verringerung dieser Gase kann dazu beitragen, den Übergang hin zu einer treibhausgasneutralen EU-Wirtschaft bis 2050 erheblich zu beschleunigen und im Anschluss daran nachhaltige negative Emissionen zu erreichen. Das EU-finanzierte Projekt REPAIR wird zwei bahnbrechende Technologien entwickeln, die Nicht-CO2-Gase wie Methan und Distickstoffmonoxid aus der Atmosphäre entfernen. Die erste wird die Emissionen abscheiden und umwandeln. Die zweite dient der direkten katalytischen Umwandlung. Beide Lösungen werden hinsichtlich ihrer Wirkungskraft im Agrar- und Landwirtschaftssektor bewertet werden. Ein erfolgreiches Ergebnis wird es der EU erleichtern, klimaneutral zu werden und eine sozioökonomische Wirkung zu erzielen.
Ziel
"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."
