Store and valorise your waste heat
Thanks to Thermal Energy Storage (TES), you can store heat recovered from industrial processes for later use, precisely when you need it. This solution is particularly beneficial when your waste heat reaches high temperatures, such as 500°C.
With thermal energy storage you can also manage energy flexibly and optimally. For example, you can draw electricity from the grid during advantageous pricing periods and store it in the thermal battery. When electricity prices are high, you exploit heat from the storage system. This approach makes it possible to store energy during off-peak, nighttime hours and use it during high-demand daytime periods.
Recovered heat can be stored in different materials, including molten salts, cement, or volcanic rocks. These materials can hold thermal energy for more than 24 hours then release it for heating, steam production, or process electrification.
What are the financial benefits of thermal energy storage?
- Using waste heat or preferential-rate electricity generates immediate, direct savings.
- Using thermal storage fully aligns with energy transition goals and complies with new regulatory and fiscal requirements related to CO₂ emissions. Heat recovery reduces your overall energy needs and can considerably reduce the impact of your energy bill.
- In 2027, the European Union will start implementing ETS2, the second component of the emissions trading system. In the first phase, emission quota acquisition became mandatory for, among others, electricity producers, airlines, and energy-intensive sectors such as the chemicals, steel, cement, and paper industries. This system is gradually being extended to many other economic sectors. Reduced fossil fuel requirements lead to reduced ETS costs.
- With thermal energy storage, you can electrify your heat production and keep your electricity bills under control at the same time.
