Greenhouse gas abatement costs of hydrogen production from underground coal gasification

摘要: Abstract The demand for hydrogen is likely to increase in the next decade satisfy projected growth of bitumen upgrading industry western Canada. This paper presents GHG (greenhouse gas) abatement costs and potential producing from UCG (underground coal gasification) along with CCS (carbon capture sequestration). Seven production scenarios are considered assess competitiveness implementing compared SMR (steam methane reforming). analysis completed through a LCA (life cycle assessment) large-scale without CCS. Considering technology as base case, UCG-CCS calculated be range 41–109 $CAD/tonne-CO2-eq depending on transportation distance site UCG-H2 plant. Life emissions higher than SMR. SMR-CCS-based UCG-CCS-based scenarios; they 87 158 $CAD/tonne-CO2-eq similar manner UCG-CCS. Consideration revenues selling CO2 captured EOR (enhanced oil recovery) reduces costs. An opportunity revenue generation realized case.
