Renewable DME (dimethyl ether) is a clean, colourless gas, similar to LPG, that is easy to liquefy and transport. Renewable DME can be produced using a variety of feedstocks such as waste from pulp and paper mills, forest products, agricultural residues, manure and municipal waste. It can either be produced from methanol dehydration or directly from synthesis gas produced via thermal gasification. Like LPG, renewable DME is gaseous at normal temperature and pressure. You probably already have some DME in your house – it’s currently around the world in the personal care industry (as a benign aerosol propellant). Thanks to the huge availability of potential feedstock and it’s clean and easy handling properties, it is now increasingly being explored for use as a clean fuel alternative. Options include blending fuel with LPG, as a replacement of diesel and gasoline and as an efficient hydrogen carrier for the future energy mix.
