Operating 28 onshore oil and gas fields, Star Energy Group plc is the leading onshore operator in terms of fields. The company believes that with the decline in flexible gas production facilities close to market in the North Sea and Irish Sea, Great Britain (GB) will need a significant expansion in gas storage capacity. To meet these demands, Star Energy aims to construct underground gas storage (UGS) facilities by converting depleted onshore hydrocarbon reservoirs both on- and offshore GB. This paper provides an overview of the UK position with respect to UGS, Star Energy's strategy and their planned developments.
Figures & Tables
The UK became a net importer of natural gas in 2004 and by 2020 will import up to 90% of its requirements, leaving it vulnerable to increasing energy bills and risk of disruption to supply. New pipelines to Europe and improvements to interconnectors will meet some demand, but Government recognizes the need for increased gas storage capacity: this may be best met by the construction of underground storage facilities. Energy security has also raised the likelihood of a new generation of coal-fired power-stations, which to be environmentally viable, will require clean-coal technologies with near-zero greenhouse gas emissions. A key element of this strategy will be underground CO2 storage. This volume reviews the technologies and issues involved in the underground storage of natural gas and CO2, with examples from the UK and overseas. The potential for underground storage of other gases such as hydrogen, or compressed air linked to renewable sources is also reviewed.
