Thermal energy storage systems for district heating & cooling - Energy
It is always more efficient to produce energy in a concentrated place, like district heating and cooling systems.In case of the district heating systems a thermal energy storage is essential. The well-known solution is the water storage. However, it requires a lot of space.The number of district cooling systems (DCS) is rapidly increasing but they have many technical challenges: peak load management, lack of space, plant size optimization and security of supply.
Overview Applications & Industries Served
Pain points
Usually our customers are facing with following difficulties:
Lack of space
No space for the water storage.
Peak load management
Peak load management
Plant size optimization

Security of supply
Plant size optimization
The solution
By using HeatTank instead of water storage, the storage size can be reduced by 60% and thanks to the optimal storage temperature and higher performance, energy efficiency is 20-40% higher.HeatTank can highly increase the energy efficiency of DCS because cooling systems should produce cooling energy only when it is the most efficient, the cheapest or completely free. Additionally, HeatTanks can be placed not just close to the central chiller unit but in separated branches of the system as well. By doing this, it is possible to turn off some branches from the DCS in case of partial needs, also reduce the heat loss through the pipes and the pumping energy.Large central storages can work in virtual power plant function as well and be part of demand response.
Features
20-50% ore efficiency
Electricity saving is between 20-50%. Free-cooling at night & Chiller optimization.
Reduced maintence
The cooling system gets more stable, requiring less maintenance and reduced operation costs.
Small
Concentrated thermal energy storage. 90% smaller than the traditional water storage and innovative rectangular shape to save space.
Backup cooling
Backup cooling available to bridge restart downtime in case of blackouts. The restart of the newest cooling systems take at least 5 minutes, which could be critical.
Remote control
Visualized energy reports on monthly base to follow the energy saving.
