Economy Minister Conor Murphy, Finance Minister Dr Caoimhe Archibald and the US Special Envoy to Northern Ireland for Economic Affairs, Joe Kennedy III, were among the first to visit the first borehole drill site. Their attendance coincided with a schools visit to the location as part of the GeoEnergy NI project's outreach and information programme where a group of pupils from Forge Integrated Primary School attended the Geo Energy Discovery Centre positioned nearby the first drill site.
The drilling and testing phase of the Stormont feasibility study is projected to last around 6 months. It will entail drilling and testing five boreholes, with four being hydrogeology boreholes approximately 250 meters deep, and one borehole core reaching a depth of 500 meters. Subsequent tests and analyses, including down-hole geophysics, will be conducted on these boreholes to determine the optimal number and depths required to supply low carbon and renewable heat to the Stormont Estate.
This project milestone marks a significant step in the broader demonstrator project, which explores shallow and deep geothermal energy at two locations in Northern Ireland. Geothermal energy is seen as crucial in achieving net zero carbon goals by 2050 and the GeoEnergy NI project serves as a showcase for its potential as a low-carbon, renewable energy source. Furthermore, it will contribute to the development of a policy and regulatory framework to facilitate its adoption across Northern Ireland. The technology is expected to offer substantial decarbonisation benefits locally and in other markets pursuing net-zero targets that have yet to realise the full potential of geothermal energy in pursuit of net-zero targets.

Welcoming the latest milestone, Economy Minister Conor Murphy said: "Our Economic Vision embraces the transition towards net zero which is both a legal duty under the Climate Change Act and a moral obligation for future generations. Geothermal energy, alongside other renewable technologies, can play an important role in how we decarbonise our economy.
"Despite being in its infancy, the geothermal sector is well positioned to thrive and with the right investment and support it can deliver real economic opportunities that will improve productivity, cultivate good jobs, and promote regional balance across the region.
"Whilst the North is fortunate to have very suitable geology for geothermal energy, it remains a relatively untapped resource here compared to other countries. That is why the GeoEnergy NI project is exploring and showcasing our geothermal potential – helping us 'discover the heat beneath our feet'.
"Geothermal offers several distinct advantages and unlike other renewables is available 24/7, whatever the weather which makes it more predictable and reliable. This is a feature that can serve to stabilise energy costs and increase our security of energy supply."
Minister for Finance, Dr Caoimhe Archibald added: "My department is committed to doing all we can to contribute to meeting the emissions targets in the Climate Change Act. We recognise and stand ready to exploit the huge economic opportunities as we transition to a low carbon economy. It is important for government to lead in tackling climate change and the decarbonisation of our economy.
"The study on the Stormont Estate will assess the potential future application of shallow geothermal to provide sustainable low carbon, renewable heating and cooling systems. We hope the project will inform a future geothermal heat network on the Estate that will replace the current fossil fuel heating systems at some of our buildings as well as helping to reduce and stabilise heating costs. The study will increase our understanding of the contribution that geothermal energy might make in decarbonising the way we heat our buildings and help inform future projects in the public and private sectors and in domestic settings.
"Ultimately, an assessment will be made of the possible contribution that geothermal energy could make towards helping meet the Executive’s carbon reduction targets."
Welcoming the progress on the project US Special Envoy to Northern Ireland for Economic Affairs, Joe Kennedy III stated: "It was very interesting to see this important geothermal project up close today and to meet the specialist team delivering it. We all know the importance of tackling the climate crisis and with it the massive opportunity to develop a green economy which helps the world move away from its reliance on fossil fuels to reach energy transition and critical net-zero carbon targets."
At Stormont, the study is examining shallow geothermal potential and its possible future application to provide sustainable low carbon, renewable heating and cooling systems for a number of pre-identified buildings on the Estate. It is hoped the project will result in a future geothermal heat network that will replace the current fossil fuel heating systems at some of the buildings on the Estate. Ultimately this will help meet the Northern Ireland Executive’s carbon reduction targets as well as reducing and stabilising heating costs. The second study is exploring the potential for a future deep geothermal borehole project on the CAFRE Greenmount campus near Antrim.
