DME s promising fuel in diesel engines, and gas turbines.
DME used in diesel engines has an advantage of a high cetane number of 55, compared to conventional diesel fuel made from petroleum, which is 40–53.
Only moderate modifications needed to convert a diesel engine to burn dimethyl ether.
DME combustion exhaust contains very low levels of particulate matter, and sulfur-free, such that dimethyl ether meets even the most stringent emission regulations in Europe (EURO6), U.S. (U.S. 2020), and Japan (2019 Japan).

Dimethyl ether or DME via https://en.wikipedia.org/wiki/Dimethyl_ether
2 CH3OH → (CH3)2O + H2O
Dimethyl ether is also relatively non-toxic, although it is highly flammable & often used as a propellent due to its low boiling point, and in engine starting fluid pressurized cans mixed with synthetic oil or propane.
DME also a major component of Map Pro gas for high temperature torches use in commercial & industrial & DIY applications.
Some OTC wart spray made with DME & propane, to freeze kill the wart infected tissue. Warts are a type of skin infection caused by the human papillomavirus (HPV)
DME also used in refrigerant blends with ammonia, carbon dioxide, butane and propene.
Dimethyl ether was the first refrigerant.
In 1876, the French engineer Charles Tellier bought the ex-Elder-Dempster a 690 tons cargo ship Eboe and fitted a methyl-ether refrigerating plant of his design. The ship was renamed Le Frigorifique and successfully imported a cargo of refrigerated meat from Argentina.
However the machinery could be improved and in 1877 another refrigerated ship called Paraguay with a refrigerating plant improved by Ferdinand Carré was put into service on the South American run.
