ReSET Project Advances Geothermal Research and Sustainable Energy Potential in Montserrat

May 28, 2026

The ReSET Project, an international research collaboration focused on understanding and developing Montserrat’s geothermal resources, continues to deliver new scientific insights and strengthen partnerships aimed at supporting sustainable energy development on the island.

The project is led by Prof Jon Blundy of the University of Oxford and brings together researchers from the University of Oxford, the Foreign, Commonwealth and Development Office (FCDO), the Government of Montserrat, the Montserrat Energy Unit, and the Montserrat Volcano Observatory (MVO). The initiative began in 2023 ), with first field activities commencing in 2024, and is scheduled to continue through to the end of 2026.

ReSET focuses on understanding the structure, dynamics, and resource potential of Montserrat’s geothermal system, including the interaction of volcanic processes, subsurface fluids, and potential energy and mineral resources. Fieldwork has included geophysical surveys, seismic monitoring, and geochemical analysis aimed at improving the understanding of the island’s geothermal reservoir.

Recent work has also highlighted the potential for value-added resources within geothermal brines, including elements such as tin, rubidium, and caesium. Researchers are investigating the feasibility of recovering these alongside geothermal energy production, contributing to broader discussions on resource efficiency and economic opportunity.

The project is also working with international partners, including a French geothermal turbine manufacturer specialising in modular geothermal systems, to assess the potential for small-scale electricity generation—approximately 1 MW—from existing geothermal wells (MON-1 and MON-2).

According to Prof Blundy, the project is entering a critical phase:

“There are a number of value metals in the geothermal brines (including tin, rubidium and caesium). We are looking at ways to recover these alongside heat for electricity.”

He also noted that researchers are reconstructing the geothermal reservoir architecture to better understand fluid pathways and system dynamics beneath the island.

The collaboration between MVO and ReSET has extended beyond field science into regional and international knowledge exchange. In July 2025, the team co-organised a dedicated SHV30 Conference session titled “Geothermal Resources: From Exploration to Sustainable Development”, which featured international case studies, including insights from Kenya’s geothermal development journey.

Earlier field campaigns and collaborative studies, including geophysical investigations supported by Canadian researchers, have contributed to mapping subsurface conditions and identifying additional geothermal targets across Montserrat.

In 2026, ongoing collaboration continues between Montserrat and Oxford partners, including data integration work and equipment retrieval from field sites to support final analysis phases of the project.

Prof Blundy emphasised the broader opportunity for Montserrat’s energy future:

“Both GoM and FCDO are very supportive and keen to capitalise on Montserrat geothermal potential. I think that there is now a remarkable opportunity for development that builds upon recent investment in PV, batteries and infrastructure. ReSET runs through end of year. Our great hope is to assist delivery of geothermal by end of year.”

The ReSET Project continues to position Montserrat as a significant site for integrated geothermal research, combining volcanology, energy systems, and sustainable development planning.
