Mobile thermal battery for utilization of surplus heat

The goal of this project is to demonstrate a novel mobile molten salt thermal storage system, a mobile “thermal battery”, which is able to: a) store surplus thermal energy, and b) to deliver this thermal energy to customers in need of thermal energy. The result is that the surplus thermal energy directly replaces fossil fuel. The concept will be demonstrated by using surplus thermal energy from waste burning for thermal soil decontamination.

The project represents an important contribution to the green transition as this thermal battery activates and monetizes surplus thermal energy which would otherwise be wasted. The project significantly

strengthens Danish Green Tech solutions by both providing a novel storage solution (commercialized by Copenhagen Atomics), reducing the waste of surplus thermal energy by converting it into a new revenue stream (Norfors) and enabling a green transition for soil decontamination (Arkil).

To put the project in perspective - the annual amount of wasted thermal energy in Denmark, corresponds to 560,000 ton CO2. The project includes both a technical and economical assessment of the thermal battery, the thermal supply side and the end-user scenario.
