Steam is widely used across various industrial sectors in numerous product manufacturing processes. In the food industry, such as at Kaskein Marja’s production facility in Lappeenranta, steam is essential for processes like sterilization and pasteurization. Traditionally, steam has been produced using fossil fuels, leading to emissions and dependency on fluctuating fossil fuel costs.
By using Elstor’s thermal energy storage system, Kaskein Marja has adopted a more sustainable and cost-effective way to produce steam.
The technology behind Elstor’s system is cutting-edge. It is a high-temperature thermal storage unit that can store energy in the form of heat and later discharge it as steam or heat as required by the process.
What makes this system remarkable is its ability to produce steam with zero emissions with a competitive price. The storage unit is charged during periods of low electricity prices — typically when renewable energy sources like wind and solar are generating excess power. When steam is needed in the production process, the stored energy is released, generating steam automatically based on the factory’s needs.
The Elstor system has an efficiency rate of more than 95%, greatly improving the overall energy efficiency of the production process. Its automation allows for real-time adjustments based on process demand, ensuring that steam is generated only when needed. This not only reduces the total energy consumption but also lowers operating costs.
From an environmental point of view, Elstor technology represents a major step forward. By relying on stored renewable energy to generate steam, the system contributes directly to the reduction of greenhouse gas emissions. It aligns perfectly with global goals for carbon neutrality and green energy transition.
Additionally, the technology supports the electricity grid by providing flexibility and storage capacity. During times of high electricity demand, the system can remain idle, storing energy only when supply is abundant, and costs are low. The charging and discharging processes of Elstor system are independent which means that the charging can be done according to the electricity grids needs while the steam production adjusts to the needs of the production facility.
By switching to this innovative steam generation method, Kaskein Marja has been able to reduce its carbon footprint while also lowering energy costs. The fully automated system requires minimal supervision, allowing resources to be reallocated to other areas of production. In addition, the use of renewable energy improves the company's sustainability profile, which is increasingly important for consumers and investors alike.
