Decarbonising energy intensive industrial processes

Our modular ultra high temperature storage system can be used to recycle waste heat, or to fuel thermal energy intensive processes with energy sourced from sustainble sources.

Various industries, ranging from food and drink or pharmaceuticals to cement and steel making, require large quantities of heat to manufacture their products. Commonly, the required energy is generated by burning fossil fuels and the waste heat is discharged into the environment.

Exergy3's thermal energy storage can increase the energy efficiency and reduce carbon dioxide emissions of industrial processes in two ways. Either, by storing the waste heat at ultra-high temperature making it available for use at a later point in time, or by converting renewable electricity into high grade heat.  

By reducing the fuel consumption and charging the system when renewable energy is generated in excess and the electricity prices are negative, the user can also reduce their energy cost and participate in balancing mechansims. 

Anchor 1


  • Positive environmental impact as the stored green heat can be used as carbon-neutral fuel for the processes. 

  • The lower amount of fuel required leads to fuel and carbon cost savings. 

  • Additional revenue can be generated by participating in demand side response programmes. 

  • Increased energy price stability by partially decoupling operations from energy price volatility. 

  • Compliance with decarbonisation regulation.
