STACs goal is to  help reduce carbon emissions on a massive GigaTon scale. 

By making STACs technology available to leading industrial companies, we enable them to use water as the refrigerant to make cooling.  This allow industries to rapidly replace the use of HFCs with water resulting in creating a world with less global warming and climate change.

Our sustainable water based solutions can help accelerate your product development, reduce project risk and optimise your supply chain. Our mission is to help your company reach the market faster with sustainable energy solutions never-seen-before.


Leapfrogging HFCs


HFCs are seen in use as refrigerants in cooling systems. STAC technology using water as the refrigerant leapfrogs the Kigali legislative agreement concerning the global phase-down of HFCs 

Maritime Sustainability


STACs technology harvest and recycle the excess engine heat and convert it to zero emission comfort cooling. A new carbon capture technology from STAC is under development.

Automotive Sustainability


Zero emission comfort cooling while extending the driving range are unique values added by STAC's technology benefitting the Automotive Thermal  Management Industry.



The global demand for cooling is growing exponentially. The use of A/C's are documented to deplete the ozone layer causing climate change and global warming. STACs technology enable the use of water as a refrigerant replacing HFCs, while saving>80% electricity.



District Heating has existed for the last 100 years all over Planet Earth.  According to research, district heating combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions having one of the lowest carbon footprints. STACs technology enable local cooling based on hot water from the district heating grid, without additional infrastructure costs.



The concept of "Thermal energy harvesting" is gaining more traction and is increasingly being recognised as an efficient way to make use of something otherwise wasted. 

Heat sources are abundant and this usually wasted energy is easily harvested by STACs technology and put to good use in other connections; such as efficient clean cooling, electricity or heating applications reducing power consumption and carbon emission
