Geothermal Energy: Clackmannanshire

Jim Shannon Excerpts

Monday 4th June 2018 Commons Chamber

[Luke Graham (Ochil and South Perthshire) (Con)]

Thank you, Mr Deputy Speaker, for granting this Adjournment debate on geothermal energy in Clackmannanshire. I am grateful for the opportunity to talk about this potentially exciting, new, greener renewable technology in the energy sector and its ramifications for Clackmannanshire, Scotland and the whole of the United Kingdom.

Known as the wee county, Clackmannanshire is the smallest council area in Scotland, situated in the south-western corner of my constituency. It is tucked away beneath the Ochil hills, flanked by Stirling to the west, Kinross-shire to the east and the River Forth to the south. Despite being home to successful companies such as Diageo, United Glass, the William Brothers Brewing Company and innumerable small and medium-sized enterprises, Clacks is a former industrial and mining community and still has some of the most deprived areas in our country. Meanwhile, geothermal energy is a form of renewable energy in its relative infancy in the United Kingdom, with opportunities still being identified and explored, and it is struggling to enter the mainstream of energy provision in the United Kingdom.

While I am sure no one would suggest that Adjournment debates usually only cater to a limited audience, addressing the niche interests of Members, with limited implications for the wider country, on the surface this debate on a relatively minor energy source in one of the smallest council areas in the country may ungenerously be described as such. However, given the limited exploitation of geothermal energy in the United Kingdom and the potential for its use in Clackmannanshire, the implications of investment and development of geothermal for the wider industry sector and the country are enormous.

I am grateful to the hon. Gentleman for giving way. I am here to support him and congratulate him on securing the debate. Does he agree that the impact of such projects on the local economy, and especially the long-term benefits, has to be a significant consideration for Government? Everybody in the United Kingdom could benefit from projects just like this.

[Luke Graham]

I thank the hon. Gentleman for his intervention, and I could not agree more. One reason why I applied for this debate is to espouse the long-term benefits of these projects and how that will align with the country’s industrial strategy.

Before I get too far ahead of myself, I want to look at the broader industry and the place of geothermal within the industry. According to the House of Commons Library, the total energy sector in the UK was worth £24 billion in 2016. In the same year, the industry as a whole invested £11 billion—the equivalent of £1 in every £16 invested in the UK. It is an industry that directly employs 148,000 workers and supports a further 582,000 through the supply chain, consulting and other energy-related activities. That is a total of 730,000 jobs supported in the UK by the energy sector. Meanwhile, around 22,000 people in Scotland are employed in the energy sector, with the oil and gas sector being a major part of that. The energy sector therefore represents an important industry not just in terms of its contribution to the total GDP of the United Kingdom, but in terms of jobs, investment, research and development and supporting industries.

Energy is important. It heats our homes, cooks our meals and runs the appliances, amenities and communications devices without which our tablets, laptops and businesses could not function. In short, it impacts on every aspect of 21st-century life. The 19th and 20th-century sources of energy have long since ceased to be seen as the future. Renewable energy sources are an ever increasing part of the suite of energy sources, and Scotland has been at the forefront of such innovations, with wind and sea power particularly prevalent in its contribution. I wholeheartedly support those steps and hope that the UK will continue to be at the forefront of such renewable energy options—not just wind and sea but others too, such as geothermal.

You may ask, Mr Deputy Speaker, why geothermal energy? In simple terms, geothermal energy is valuable because it is generated and stored in the earth. It is heat extracted directly from the earth. It is generally available via shallow geothermal ground source heat pumps, which use the heat stored in the earth to generate electricity or provide heating. Geothermal is considered a renewable form of energy due to the vast amount of heat inside the earth and the continuous production of additional heat derived effectively from the earth’s core.

It is important to understand that geothermal energy is not the same as fracking, as some have tried to claim. For clarity, geothermal technology uses things such as mine water, closed boreholes and surface water, none of which has any similarity to fracking. Fracking is a process used to break up rock at great depths to release gas from ancient plant deposits. In the UK, this typically happens 2.5 km below the surface using a process involving large diameter boreholes and huge hydraulic pressures, and those are part of the concerns currently being debated. By contrast, with geothermal, the typical closed loop borehole, such as the one that would be used in Clackmannanshire, is no more than 200 metres deep, with a small diameter, and is installed in the same way and to the same standards as a water well.

We should consider the environmental impact, or relative lack thereof, of geothermal energy. It does not require combustion, unlike traditional energy plants, so it emits very low levels of greenhouse gases. It also eliminates the mining and transportation processes involved in fossil fuel energy generation. Finally, it takes up very little surface land, putting it among the smallest footprint per kilowatt of any power generation technology, including coal, nuclear and other renewables.
