Manders, A.M.M. (author), Ketzel, M. (author)Air quality in Europe has been considered an issue since the 1950s and has improved considerably over the past decades. Emissions in 2018 were reduced considerably as compared to 2005, with emission reductions of SOx of more than 50%, of NOx of about 40% and of PM10 of about 25%. Nowadays, many areas comply with the limit values of the European...bookPart 2023

(author), Denier van der Gon, H.A.C. (author), Röckmann, T. (author)Natural gas is considered a bridging technology in the energy transition because it produces fewer carbon emissions than coal, for example. However, when leaks exist, methane is released into the atmosphere, leading to a dramatic increase in the carbon footprint of natural gas, as methane is a much stronger greenhouse gas than carbon dioxide....article 2023

(author)Natural gas is a potent greenhouse gas but remains an attractive energy resource for a good number of reasons. Because complementing the use of natural gas with carbon dioxide capture and storage yields several drawbacks, producing synthetic natural gas instead could be an interesting alternative. Methanation is an established and well-known...article 2022

(author)Natural gas based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO2 from natural gas reforming are captured and permanently stored, such hydrogen could be a low-carbon energy carrier. However, recent research raises questions about the effective climate impacts of blue hydrogen...article 2022
