Current status and technology development in implementing low carbon emission energy on underground coal gasification (UCG)

Although coal mining has played a substantial role in world’s development as critical fuel source for at least 25 years, its value is partly offset by the massive environmental issues it presents during combustion. The shift to net-zero CO 2 emission will open unique possibilities new technological models which progressive studies and policies, development, modernization play significant role. Therefore, collection of technologies been proposed, one cost-effective Underground Coal Gasification (UCG) coupled with carbon capture storage (CCS) utilization technology (CCU) UCG-CCS/CCU. This paper reviews current status implementing low energy on underground gasification. study, therefore, leads discussing modern stage gasification recent pilot operations, developments growing market. At same time, provides reference combined CCUS technology.
