As a fuel
DME can be used as a fuel in diesel engines,petrol engines (30% DME / 70% LPG) and gas turbines. It works particularly well in diesel engines due to its high cetane number, which is greater than 55 compared to diesel which is 38-53.
Currently the EU is considering DME in its potential biofuel mix in 2030.
I believe DME is the cetane booster used in a lot of diesel fuel additives, like FPPF. Isn't it also one of the gasoline additives for "oxygenated fuels" used seasonally for smog reduction in Cali and Arizona?
