Arverne Group and Crédit Agricole Pyrénées Gascogne have announced a partnership to develop a surface geothermal energy project, marking a strategic move to integrate renewable heating solutions into regional infrastructure. The collaboration aims to leverage Arverne’s technical expertise in subsurface resources alongside the regional banking group’s local footprint to accelerate the energy transition in southwestern France.
This initiative represents a growing trend among French financial institutions to diversify their portfolios by backing localized, low-carbon energy production. By focusing on surface geothermal—a technology that extracts heat from the shallow subsurface—the project is designed to provide sustainable thermal energy for municipal or industrial use, reducing dependency on fossil fuel-based heating systems.
Strategic Alignment in Renewable Energy
The partnership brings together two entities with distinct but complementary roles. Arverne, led by CEO Pierre Brossollet, has established itself as an operator focused on the development of geothermal energy and lithium extraction. Under its Arverne Earth division, the company specializes in identifying and exploiting geothermal reservoirs that can provide stable, baseload energy. According to the company’s official corporate profile, the firm prioritizes projects that align with European decarbonization targets and local energy autonomy.
Crédit Agricole Pyrénées Gascogne, represented by Director General Paul Carite, serves as the financial anchor for the venture. As a regional entity of the Crédit Agricole Group, the bank has committed to supporting the “territorial transition” by financing projects that contribute to the sustainable development of the Pyrénées and Gascogne regions. This financial backing is essential for the high upfront capital expenditure (CAPEX) typically associated with geothermal infrastructure, which requires significant investment in drilling and heat distribution networks before revenue generation begins.
How Surface Geothermal Works
Surface geothermal energy, often referred to as low-energy geothermal, utilizes the constant temperature of the earth a few meters to a few hundred meters below the surface. Unlike deep geothermal projects that target high-temperature steam for electricity generation, surface geothermal is primarily used for heating and cooling buildings via heat pumps. The French Agency for Ecological Transition (ADEME) notes that this technology is highly efficient for communal heating networks, as it allows for a significant reduction in greenhouse gas emissions compared to gas or oil boilers.

The partnership intends to identify specific sites within the Pyrénées Gascogne region that possess the geological characteristics necessary for efficient heat exchange. By utilizing established, low-risk thermal extraction methods, the project seeks to provide a reliable energy alternative for local businesses and public facilities. The economic viability of these projects is often bolstered by the long-term price stability of geothermal energy, which is immune to the volatility of global fossil fuel markets.
The Impact on Regional Energy Policy
The collaboration between a financial institution and a specialized energy developer reflects a broader shift in how regional energy projects are funded in France. Traditionally, such infrastructure projects relied heavily on state subsidies or large national utilities. The involvement of a regional bank signals that geothermal energy is increasingly viewed as a bankable asset class with predictable, long-term cash flows.
For the Pyrénées Gascogne region, the project serves as a pilot for decentralized energy production. By producing heat locally, the region can mitigate the risks associated with energy transmission losses and market price spikes. This aligns with broader national policies, such as the Climat et Résilience Act, which encourages the development of renewable energy sources at the local level to meet France’s objective of achieving carbon neutrality by 2050.
Project Outlook and Next Steps
As the partnership enters its implementation phase, the focus will shift toward technical feasibility studies and environmental impact assessments. These steps are standard for geothermal developments, ensuring that the extraction process does not disrupt local water tables or geological stability. The companies have indicated that the success of this initial project could serve as a blueprint for future expansions across the bank’s operational territory.

Investors and stakeholders are expected to look for updates regarding the specific locations selected for development and the projected capacity of the heat production units. Arverne Group continues to manage its portfolio of geothermal assets, while Crédit Agricole Pyrénées Gascogne maintains its role in facilitating the necessary capital flows to move these plans from the design stage to active operation. Further details regarding the project timeline and specific site milestones are expected to be disclosed through official company communications in the coming fiscal quarters.
