    DME in the Diesel process

  • ConclusionsConclusions

    - DME has good fit to the drivers for alternative fuels

    DME l l l k th t f t bli h d- DME largely lacks the support from established economic interests

    - DME simplifies diesel engine technology at todays and future emission levels

    - DME in diesel process is soon ready to move from advanced engineering to commercial applications
