To Frack or not to Frack

To Frack or not to Frack

          Christiana Figueres, the executive secretary of the UN Framework Convention on Climate Change, recently said that 'The coal industry needs to change rapidly to help prevent global warming by leaving most of the fuel in the ground'. It was against this background that Pembrokeshire South East Energy Group welcomed John Childs from Safe Energy Wales to explain the recent developments being proposed in the Swansea area.

          He started by explaining the method used to 'frack' (short for fracturing). This involves drilling down vertically then horizontally. Water, including numerous various chemicals not named because of confidentiality - is then injected under high pressure to create fractures to release the methane held in the rock.

          Coal Bed Methane (CBM) is the name given to this method for accessing fossil fuels. The shale gas seams are deeper than coal seams which are closer to the surface and stretch across South Wales including Pembrokeshire.

          The UK Government has designated large areas of Britain as suitable for exploitation and issued licences many in South Wales. The site covers the whole of Swansea. Permission has been given for test drilling of 6 holes just north of the M4. At this stage fracking will not be used. However should methane be found the normal progression is that initially the gas comes out naturally but fracking follows as it ceases to be released unassisted. The question of how the waste contaminated water is dealt with one which needs to be addressed. Generally only half comes back to the surface and that which does is held in 'ponds'.

          The pads on which the engineering work takes place do not require Environmental Impact Assessments as they only cover 7,000sq metres. However new pads and wells will be needed should permission be given.

          Underground Coal Gasification UCG) already has been granted 22 licences across the UK one in the Louchor Estuary. Many older readers will remember the time when coal gas was produced by carefully controlled burning of coal in local gas plants. The aim with UCG is to pump oxygen/air into coal seams, set fire to them in a controlled way to extract the gas. This process leads to massive CO2 emissions (as of late 2013 Carbon Capture and Storage had never been successfully implemented on a commercial scale). Toxic coal tars are left in the resulting cavity often leaching into ground water.

          In the course of discussion a number of points were raised. The UK Government controls energy policy and is in favour of seeing these types of projects developed. They have produced planning guidelines which place national interest before local interest unlike planning for windfarms which states that the interests of the local community must be taken into account. Their belief that these developments would reduce the cost of gas has to be considered in the context that the UK is interconnected to the continent - gas can flow to and from - and it will be sold to the highest bidder. Comparisons were made by some members to the USA where gas prices had fallen dramatically due to the exploitation of shale gas. However it was pointed out that until recently due to distribution problems most US gas was sold to the domestic market. Little was sold on the more profitable international market. George W Bush also removed many environmental protections most noticeably concerning water. Unlike the UK the US is a large country with vast areas being sparsely populated.

          Members and friends of PSEEG felt that they had learnt a great deal about an area of energy policy that has come to the fore very recently and could have large implications locally.
