DME gains ground in Canada
Dimethyl ether, or DME is a mixture of hydrogen and carbon monoxide that can be produced from biomass, natural gas or coal.
DME has the potential to replace diesel fuel because it produces 95% fewer greenhouse gases, no soot, low levels of nitrogen oxide and no sulphur dioxide.
Calgary-based GV Energy is proposing to build a biorefinery to produce DME in Terrace, British Columbia.
It will use wood fibre collected from the forests around Terrace. It signed a tentative agreement with Terrace in November in which the city set aside a 100-hectare site in an industrial park for the biorefinery, which is to use up to 3,000 m3 of wood fibre a day. The process would turn the fibre into a gas to make methanol, which would then be converted into DME.
