Abstract
UCG facilitates deep-seated coal seam utilization in the Jamalganj deposit (Bangladesh) by producing synthesis gas for electricity and fertilizer production. Based on previous studies which assessed UCG combined with carbon utilization in a urea process, we further investigated excess CO2 utilization by means of enhanced gas recovery (EGR) at the Bahkrabad gas field. Our techno-economic modeling results demonstrate that an economic and carbon neutral UCG operation with urea production and EGR is feasible. Thus, this approach introduces a bridging technology that can tackle Bangladesh's fertilizer and power supply shortages in addition to increasing gas recovery from Bangladesh's depleting natural gas deposits.
