Bengt Dahlgren Stockholm Geo, founded in 2014, specializes in planning and implementation of geoenergy projects (ground-source heat pumps and underground thermal energy storage). We help our clients develop and design sustainable energy solutions, focusing on geothermal heating and cooling, thermal energy storage, and data-driven energy optimization. Our expertise includes borehole thermal energy storage, heat pumps, district heating and cooling, energy system modeling, field tests (TRT, DTRT, heat tracing), energy markets, energy planning and machine learning for energy applications. Bengt Dahlgren Stockholm Geo AB is part of a larger technical consultancy group (Bengt Dahlgren).
