Usually gas engine work in a Virtual Power Plant system. It means that the electricity generation is more important than the heat generation, so the heat generation is fluctuating and it is different in time than the needs of the heat.Besides, that the biggest problem with gas engines is that after they stop there is a huge amount of heat still in the overheated material of the engine (latent heat) and usually it can not be used because of the water temperature would be too low.
Usually our customers are facing with following difficulties:
Delay in heat generation and usage
The heat generation and the need for the heat are different in time.
After the gas engine stops, there is a huge amount of heat still in the overheated material which can not be used.
When the heat generation of the gas engine is too high or there is no need for the heat, HeatTank can store it for later usage.When the engine operates, the steel structure heats up to 150-200 °C. When it is turned off, the heat remains in the structure. A huge amount of that heat could be recovered from the steel structure but its temperature would be too low to be used for heating. HeatTank makes it possible to recover the heat from the engine by increasing the temperature of the stored heat.
Store and use the extra heat later also use the heat which is stored in the material of the engine.
High performance and fast availability. Stores in different temperature levels..
Environmentally friendly materials.
Concentrated thermal energy storage. 60% smaller than the traditional water storage and has an innovative rectangular shape to save space.
Visualized energy reports on monthly base to follow the energy saving.
Our HeatTank has been working since February 2020 at E.ON Hungary for gas engine heat recovery. The gas engine is working in a Virtual Power Plant system, so the electricity generation requires much more flexibility than heat generation, so (the heat generation and) the needs are not in the same time. With HeatTank we can save the waste heat when the generation is too high or there is no need for the heat. Besides, the gas engine block contains a huge amount of heat after they stop in the overheated material of the engine. Usually it can not be used because the water temperature would be too low, but with our storage we are able to after-heat the water with the prestored waste heat.
