Life-cycle assessment of oil recovery using dimethyl ether produced from green hydrogen and captured CO₂.

ABSTRACT: Hydrocarbon fuels are widely recognized as significant contributors to climate change and the rising levels of CO₂ in the atmosphere. As a result, it is crucial to reduce the net carbon intensity of energy derived from these fuels. This study explores the feasibility of using dimethyl ether (DME), produced through the hydrogenation of CO₂, as a low-carbon method for generating electricity from hydrocarbon fuels. The proposed approach involves capturing the emitted CO₂ during combustion and utilizing it to produce the necessary DME in a closed cycle. It is shown that for a mature reservoir in the Middle East, this method can mitigate approximately 75% of the CO₂ emissions released from burning the produced oil. By incorporating zero-carbon electri
