Erdwaermedich

About

Founded in 2023, Erdwaermedich is a co-op headquartered in Bremen, Germany with approximately 1-10 employees specializing in Geothermal, Energy Storage.

ErdwärmeDich Anergienetze eG is a cooperative utility operating in Northern Germany (Bremen, Oldenburg, and surrounding regions) that develops and manages shared geothermal heating networks. The organization finances and constructs ground-source heat pump systems serving multiple households through common district networks. Each system comprises boreholes (typically 100-300 meters deep), circulation lines, and individual household heat pumps. The cooperative pre-finances infrastructure costs using German federal efficiency heating network grants (BEW program) and recovers costs through monthly usage fees over a 20-year period. Members form neighborhood clusters of minimum 17 households. The systems use brine-water heat pumps to extract geothermal energy at approximately 50W per meter depth in the Bremen region, providing heating and hot water supply. The model emphasizes cooperative governance, cost reduction through bulk procurement, and environmental benefits of CO2-free heating.
