This document summarizes a presentation given at the 8th International DME Conference on the basics of dimethyl ether (DME) as a fuel and chemical feedstock. The presentation provides an overview of DME properties, production technologies, markets, storage and distribution. It discusses the key global players and organizations involved in DME development since the 1990s. The presentation was given by Dr. Ronald Sills, Co-Founding Director of the XTL & DME Institute, an educational organization focused on all aspects of DME and related fuels/feedstocks. The presentation concludes by noting the DME community's goals of expanding DME use beyond trucks and cars to other industries and modes of transport.

9. Closing Remarks
9XTL & DME InstituteSM
The DME community has its sights beyond heavy-duty trucks and passenger
cars; that is, across multiple industries including locomotive, marine
transportation, as a fuel for power generation and growing the LPG blend stock
market.
• To achieve these purposes and build the DME ecosystem, the DME community must
continue working together and recruit new members.
