The abstract is sparse, and the authors reference what we contend is outdated thinking about CO2 - i.e., "underground storage". But, the article is more evidence that liquid fuel and electrical power can be produced from coal, at the same time, in the same facility, with resultant economic and environmental benefits.

Summary
We present energy and carbon balances and cost estimates based on detailed Aspen Plus process simulations for five plant designs to co-produce dimethyl ether (DME) and electricity from coal. Four of the designs include capture of CO2 for long-term underground storage. We also illustrate the potential DME offers for reducing emissions by facilitating a shift to more energy-efficient vehicles."
