Underground coal gasification with CCS: a pathway to decarbonising industry

Underground coal gasification (UCG) opens up the prospect of accessing trillions of tonnes of otherwise unmineable coal. When combined with carbon capture and storage (CCS), UCG offers some attractive new low-carbon solutions on a vast scale. This paper has several aims: to review key developments in technologies for UCG, CCS and CO2 storage in coal seam voids; to quantify the scale of the opportunity that these technologies open up; to examine...
