Gex co-ownership – 3 apartment buildings · 61 homes

Shallow borehole geothermal energy used as a natural thermal storage source for heating and domestic hot water. Financed through an energy performance contract, energy savings certificates (CEE) and the Heat Fund, with no upfront cash outlay for the co-ownership.

Value propositions

Decoupling production and consumption, on every site

Inter-seasonal geo-storage

The subsoil as a natural thermal battery: heat stored in summer, released in winter. AI control, energy performance contract financing available, zero CAPEX.

Ice-based cold storage

Produced during off-peak hours, released during peak hours. Three ranges suited to each consumption profile, with reduced subscribed capacity and service continuity in the event of a breakdown.

Mobile thermal battery

Lost industrial heat becomes renewable cooling on a remote site. Reversible thermochemical storage, zero loss in transport, a Cooling as a Service model with no investment.

Stationary battery energy storage systems (BESS)

Storage of surplus PV, load curve smoothing, participation in balancing markets. Three financial models available, including 100% Eren financing with shared savings.
