Associating the subsurface with the energy transition may appear incongruous. Wind turbines, photovoltaic panels, or possibly hydroelectric dams and nuclear power stations come more readily to mind.

And yet, the energy and ecological transition that will gradually lead us to develop low-carbon energy will require us to make increasing use of the resources and potential of the subsurface.

The subsurface is an essential asset for a successful energy transition

Issue 27 of BRGM's Géosciences magazine investigates subsurface solutions: geothermal energy (the government's geothermal energy plan, geothermal energy in urban areas featuring an interview with Cindy Demichel, CEO of Celsius Energy), CO2 storage, heat storage and hybridisation of these different solutions with other sources of renewable energy (solar, biomass, wind, etc.).

It also looks at access to mineral resources, which are vital to the success of the energy transition, including an editorial by Agnès Pannier-Runacher, Energy Transition Minister, who sets out her ambition to make France a pioneer in the area of "responsible mining".

Finally, this issue also looks at the conditions required to develop the use of the subsurface as part of the energy transition, in particular the essential involvement of the public in decision making.

BRGM's Géosciences journal

BRGM’s journal is written for an informed but not exclusively scientific readership. Géosciences, a six-monthly scientific and technical journal launched in 2005, addresses research aspects and support for public policy and industrial technologies, in France, in Europe and around the world.

The editorial content deals with major geoscience issues, such as water, natural hazards, urban geology, geology and health, the natural environment and heritage, mineral resources, polluted soils and waste, and climate change.

The scientific content is systematically complemented with a societal perspective. Authors may, for example, address legal, economic, geopolitical, social or environmental issues as well as the geoscientific aspects of their topic.
