In search for additional markets, in the mid-to late 1990s, Amoco partnered with the General Electric Co. (GE), and in cooperation with the Electric Power Development Corporation of Japan (EPDC) tested DME as a gas turbine fuel (Basu et al., 2001; Fleisch et al., 2001; Basu and Wainwright, 2001). The results showed excellent performance with a measurable improvement in efficiency and the same low emissions as natural gas. Most importantly, GE offered guarantees for DME in most of their advanced turbines.
