CFG Géothermal : The start of a new era | BRGM

Initiated in 2019, the opening up of CFG Géothermal’s capital, desired by its shareholder BRGM Invest, became effective in 2024 with the entry of Beicip-Franlab in April. The proximity of this IFPEN subsidiary gives the company a broader international dimension, the promise of penetrating new markets and the possibility of drawing on related and complementary know-how that strengthens its service offering and credibility in high-stakes markets.

At the same time, CFG Géothermal has updated its image, graphic charter and website. Supported by the entire company, this upgrading of the communication strategy is designed to increase the company’s appeal, to customers and prospective customers, and to future employees.

Production activity was intense in 2024, with turnover of €6.37M, up by 17% compared to 2023. Four new employees joined the workforce during the year to boost production capacity and prepare the company for future challenges. Undertaken at the end of 2022, CFG Géothermal’s transformation in line with the Ambition 2030 plan is well underway, even if there is still room for optimisation and more efficiency.

Project-management business remains buoyant, with the completion of geothermal doublets at Villetaneuse, Roissy-Charles de Gaulle (ADP group) and Pantin, and major work (workover operations) at the Meaux and Rueil-Malmaison sites.

The many studies carried out outside the Paris Basin also show that geothermal energy is now an integral part of the energy transition equation throughout France. In response to this demand, CFG Géothermal has developed a de-risking service that speeds up the technical and economic assessment of a project in a new area, using advanced geophysical and numerical modelling technologies. We should also note the completion of a major study by the CFG-Beicip-Franlab consortium, to assess geothermal lithium resources in the Rhine Graben and the undertaking of studies on island regions (Mayotte, La Réunion) as part of electrical power plant projects.

2024 was also a good year for the maintenance and operations monitoring business, with sustained increase in the number of contracts, an intensification of breakdown interventions and the development of related services. At Champigny-sur-Marne, for example, CFG Géothermal installed and commissioned the equipment for the new composite doublet.

Organised by the company, the Petits Déj de la Géothermie (Geothermal Breakfast meetings) were a great success in 2024. The 7th edition attracted around a hundred French and European decision-makers to discuss deep geothermal energy. The company has also forged a number of partnerships with universities and professional associations. These collaborations demonstrate CFG Géothermal’s commitment to supporting innovation and training specialists for the future, to consolidate its key role, which already spans four decades, in the development and support of geothermal energy in France.
