The need

Energy is wasted in nearly every thermal energy system worldwide. €20 billion or 250 million metric tonnes of CO2 equivalent greenhouse gases could be saved in Europe alone through optimal thermal energy storage.

The solution

Traditionally, heat is stored by changing the temperature of the water. Instead of water, HeatTank incorporates special biomaterials, called phase change materials (PCM). By melting and solidification it is possible to reduce storage size by almost 90%, saving at least 20-50% energy, with a total return on investment of between 3-5 years. Energy systems become more efficient and operational costs reduced.
