DME gains ground in Canada

Canada’s forest industry has been hit hard by the recession. Now increasing efforts could resurrect the industry as it branches out to renewable energy.

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.
