According to this article it burns _very_ cleanly. I am not an expert in these matters so they might not be stating the whole truth. https://www.frontiersin.org/articles/10.3389/fenrg.2021.663331/full begin quote << Work by Willems at Ford has shown that in engine tests, not only is there zero SOx emissions associated with DME fuels (because the fuel is not fossil-derived) but due to the reduced carbon content in the molecules compared to diesel, CO2 emissions can be as low as 3 g/km, compared to EU 2020 standard diesel car emissions of 95 g/km (European Council directive, 443/2009; European Council directive, 443/2009). Furthermore, as less air is needed and the flame temperature is lower there are practically zero NOx emissions, and because there are no C-C bonds in the ether molecules particulate matter (PM or soot) is also practically zero (Lee et al., 2016). Therefore, compared to current electricity grid mixes and emissions in power generation for EVs, the full scope life cycle emissions for DME-CIVs could be considerably lower.>> end quote Harry
