Greenhouse gas abatement costs of hydrogen production from underground coal gasification (UCG)

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