The ground beneath our feet is becoming increasingly valuable. It’s a source of heating and energy, but also provides potential storage for heat and cold. Also, smart combinations can be made to use the surface water or other water bodies as energy sources in green city concepts. All of these applications are now possible thanks to innovative technologies. With our expertise in the subsurface, we help our clients to come up with green and sustainable energy solutions.
