Carbon-capture and UTILISATION is better than simple storage, Stag Energy tells UK Govt

emissionsEXCLUSIVE report by Scottish Energy News

An Edinburgh-based energy projects development company is urging the UK Government to adopt a new carbon utilisation and policy rather than ‘simple’ carbon-storage.

Whilst not presently active with a specific project in the area of carbon capture and storage, Stag Energy has been involved in reviewing the maturity of technologies with potential to contribute to a low-carbon energy sector.

Led by Dr Andrew Stacey, Stag Energy said that shifting focus from carbon capture and storage  to carbon capture and utilisation is the appropriate course of action for the UK Government to support with the prospect of making a long term, commercially viable contribution to the low carbon energy challenge.

In its response to a UK government consultation, Stag Energy said: “We feel it would be appropriate for the committee to consider Carbon Capture and Utilisation (CCU) as a sustainable solution to the CO2 question and to suggest government give greater consideration of support to CCU as an avenue which provides a useful product from a dangerous waste, and which would utilize CO2 as a “societal benefit” by making a major contribution to the challenge of energy storage.

“Such an approach would be compatible with several other members of the EU where the European Commission’s encouragement to address adding value to the energy market through the integration of renewables, fossil fuels, and storage appears to be well recognised.

“There is already a UK network, CO2Chem, where the focus of research is on the utilisation of Carbon Dioxide as a feedstock for chemical synthesis. Synthetic Natural Gas (SNG) is one of the cases being considered of how CO2 can be utilised in helping Government achieve its targets in decarbonisation, security of supply, and integration of the energy system.”

Energy storage enables the intermittent renewables to be matched to demand, making them more effective and preventing curtailment. The SNG process utilises excess renewable energy to produce hydrogen gas, which then reacts with carbon dioxide to generate SNG.

Stacey added: “Synthetic natural gas, which has the same composition as Natural Gas, can be defined as ‘energy storage’.

“It is a key example of how a valuable, sustainable product can be created which addresses the challenging question of energy storage while at the same time utilising the harmful waste CO2.”

Prior to establishing Stag Energy, Grant was Senior Vice-President with InterGen, overseeing the creation of a 17,000MW global generation portfolio between 1994-2002. His responsibilities included a $6 billion investment portfolio.
