6 Risø DTU, Technical University of Denmark
Dimethyl Ether (DME) as Transportation Fuel
Lower greenhouse gas (CO2 and NOx) and soot emission
Can be used in present diesel engine technology with some modification
Comparable engine efficiency with diesel
7 Risø DTU, Technical University of Denmark
How to Split CO2 and H2O?
Building block for any synthetic fuel synthesis
Synthesis gas
8 Risø DTU, Technical University of Denmark
Concept of SOEC stack
9 Risø DTU, Technical University of Denmark
Proposed DME synthesis process
10 Risø DTU, Technical University of Denmark
Abundant renewable energy can be used in SOEC to convert steam and CO2 to synthesis gas, which can
catalytically be converted to dimethyl ether.
