Underground Coal Gasification (UCG) with CCS for Jamalganj Coalfield. An alternative solution for Sustainable Energy Development of Bangladesh

      Аннотация: Underground coal gasification (UCG) is a method of gasifying Coal in-situ, considered as a cleaner and alternative mining method of capturing energy from underground coal specially which coalfields cannot be exploited by other methods. Due to some socio-political reasons, we are not able to mine the coal reserve of Bangladesh but only a little amount by underground coal mining. The Jamalganj coalfield has a reserve 1,053 million tons at the depth of 640-1,150 m. So, Conventional underground or open cut method is not possible here, but a a successful 550 MW power plant is designed by coal feeding 55.2845 kg/sec amount and produced syngas from this unexploited coal resource. This integrated underground coal gasification - CCS - IGCC System could offer many advantages here over the conventional mining and gasification process. This is how, this technology could help Bangladesh to mitigate the increased demand of safe energy with securing energy security as in a sustainable approach.
