Egyptian researcher Ahmed Osman Ahmed believes diesel fuel tech can still be useful even if the substance itself goes extinct. The Queen’s University-based scientist tells The National’s Gavin du Venage that Dimethyl Ether (DME) is a clean and renewable alternative to diesel that uses the same compression engines minus all the toxins. “It can be used for cooking and heating as a replacement for propane or in transportation as a fuel in cars or even in the power generation to produce electricity,” Ahmed says. It could be especially useful for developing countries like Egypt, as landfill biogas could be used as feedstock for DME, he adds.
