About Geothermaq

Geothermaq is an independent company specializing in shallow geothermal energy that supports businesses in the industrial and service sectors, as well as local governments, in their energy transition. Our mission is to transform the natural thermal potential of the subsurface into an efficient, sustainable, and carbon-free heating and cooling solution.

Our History

Since its founding in 2021, Geothermaq has established itself as a leading player in subsurface engineering. Our journey is guided by a constant ambition: to identify and implement the most appropriate geothermal solution to meet the heating and cooling needs of the project owners who place their trust in us.

With more than 120 studies and projects completed throughout France, we have evolved to offer comprehensive support, from initial geological and hydrogeological assessments through to the delivery of turnkey projects.

Our Values

Technical Excellence & Rigor

Our commitment to providing our clients with technically and economically optimized solutions drives us to continually challenge ourselves and advance our scientific understanding of the thermal phenomena that govern the behavior of the subsurface. Our expertise has been recognized by the RGE OPQIBI 10.07 certification since 2022.

01

Environmental Commitment

We are working toward the practical decarbonization of buildings. By harnessing geothermal energy, we help our clients reduce their CO2 emissions by up to 95 percent while protecting water resources.

02

Independence & Consulting

As an independent company, our priority is to optimize your financial interests (CAPEX/OPEX). We have expertise in all types of geothermal energy and recommend the technological solution best suited to the geological conditions of your site.

03

The Leaders

Geothermaq was founded by two experts with a passion for the subsurface who were determined to make shallow geothermal energy more widely accessible in France. Combining strategic vision with scientific rigor, Jérôme PORFIRIO and Frédéric PASCAUD lead the company with a clear goal: to make geothermal energy the cornerstone of decarbonization in the industrial and service sectors.

Jérôme PORFIRIO

"My goal for Geothermaq is to provide project owners with a 'turnkey' solution that overcomes all the technical and financial barriers to geothermal energy. We don't just design systems; we are committed to their actual performance and long-term profitability."

Jérôme PORFIRIO - President - Technical Director

Arts & Métiers Engineer

"The success of a geothermal project begins with a thorough understanding of your needs and the search for an appropriate solution. My role is to identify and implement the support that meets your energy transition goals while taking into account the geothermal resources available at your site."
