Abstract
Oxyfiring with CO2 capture is a promising technology for reducing CO2 emissions from the transportation fuel sector. However, it requires a significant amount of energy to generate oxygen. Authors examine the potential for oxyfiring to reduce life-cycle GHG emissions from transportation fuels derived from in situ and ex situ oil shale and ex situ oil sands in the Uinta Basin of Utah.
They also examine the effect of oxyfiring with CO2 capture on the net energy return (NER). Results suggest that oxyfiring could help some unconventional sources of crude oil, such as ex situ production of oil sands and oil shale, meet a LCFS. However, oxyfiring with CO2 capture reduces NER.
