The Government of Montserrat has taken a further step towards advancing the island’s geothermal energy resources following a productive meeting between the Honourable Premier of Montserrat Reuben T. Meade, and Guillaume Arnaud of Enogia, a French technology company specialising in Organic Rankine Cycle (ORC) systems for converting heat into electricity.
The meeting focused on the potential development of Montserrat’s geothermal resources and the opportunity to establish an integrated model combining renewable electricity generation with the productive use of geothermal heat, including the potential development of a spa and related thermal applications.
Preliminary Technical Work Underway
The discussions were supported by preliminary technical work examining the potential application of ORC technology to Montserrat’s MON-1 and MON-2 geothermal wells. Based on preliminary assumptions from 2025 flow-test data, both wells have been modelled with preliminary flow rates. These figures remain subject to further testing and engineering validation.
Enogia has experience with geothermal applications in which ORC systems generate electricity while cooling geothermal water for subsequent uses, including geothermal bathing facilities in Japan and Iceland.
Modular Approach
The technical discussions have also considered a modular architecture in which ORC units could potentially be deployed close to individual wellheads. Such an approach could allow for progressive development, reduced piping and civil-work requirements and greater operational flexibility.
An intermediate heat-exchanger loop would also allow the geothermal brine to be isolated from the ORC equipment, with the final configuration to be determined following further technical assessment of geothermal chemistry, scaling, efficiency, maintenance and cost considerations.
A Further Step Towards Montserrat’s Geothermal Future
Premier Meade welcomed the discussions as an important step in examining how Montserrat can make productive use of its geothermal resources:
“Montserrat has a once in a lifetime opportunity to develop its geothermal resources in a way that strengthens energy security, economic development and creates new opportunities for the people of Montserrat. Our discussions with Enogia have helped to advance our understanding of what may be technically possible, and we look forward to continuing that work on the island.”
Guillaume Arnaud said:
“We were very pleased to meet with Premier Meade and to discuss the potential for geothermal development in Montserrat. The preliminary technical work gives us an interesting basis for further investigation, and we look forward to visiting Montserrat and continuing the discussions with the Government and its technical partners.”
The discussions are non-binding and do not constitute a contractual commitment by the Government of Montserrat or Enogia. The Government of Montserrat will continue to assess any future development in accordance with applicable technical, financial, regulatory and procurement requirements.
