With the development of modern technology to produce energy and capture carbon dioxide by carbon capture and storage (CCS) there is renewed interest in the exploitation of the Durham Coalfield reserves by underground coal gasification. This is strategically important to local energy-intensive industries, such as the commodity chemical and steel members of the Northeast of England Process Industry Cluster (NEPIC). ==References==
