The UK's Energy and Climate Change secretary Edward Davey has announced that exploratory hydraulic fracturing for shale gas can resume in the UK, subject to new controls to mitigate the risks of seismic activity.
Mr Davey said: “Shale gas represents a promising new potential energy resource for the UK. It could contribute significantly to our energy security, reducing our reliance on imported gas, as we move to a low carbon economy.
“My decision is based on the evidence. It comes after detailed study of the latest scientific research available and advice from leading experts in the field. It is essential that its development should not come at the expense of local communities or the environment. Fracking must be safe and the public must be confident that it is safe.
“We are strengthening the stringent regime already in place with new controls around seismic risks. The new Office of Unconventional Gas and Oil, led by DECC, will be able to focus regulatory effort where necessary to meet the needs of future production.
The department is also commissioning a study of the possible impacts of shale gas development on greenhouse gas emissions and climate change.
To date there has been no commercial shale gas production in the UK. Exploratory fracking has been suspended since May 2011 after two small seismic tremors were detected near the country’s only fracking operations in Lancashire.
The new controls include:
• A compulsory prior review before fracking begins to assess seismic risk and the existence of faults;
• A fracking plan must be submitted to DECC showing how seismic risks will be addressed;
• Seismic monitoring must be carried out before, during and after fracking;
The study of the possible impacts of shale gas development on greenhouse gas emissions and climate change will consider the available evidence on the lifecycle of greenhouse gas emissions from shale gas exploitation and the need for further research.
