Combi Solutions

Around the clock heat supply with Heliac’s solar field and RockStore solution. Carbon-free and cost-effective.

This is how it works

Heliac’s combi solutions unite our proprietary solar thermal technologies with our newly developed RockStore thermal 
storage solution.

The result is a powerful and economical way to secure continuous CO2-free heat supply up to 300 °C in both private and public sector installations.

Depending on individual temperature requirements, it’s even possible to integrate a steam turbine and thereby enable
heat-based electricity production.

Thanks to its flexible configuration, the combi solution allows
for integrations into existing installations such as PV plants,
power grids or to utilize waste heat. These applications only
make for an even more robust economy.
