Steam is critical in food production, as the entire process depends on it. Steam is used for heating cooking pots, heat treatment and sterilization – for all steps that require high temperatures. With the new solution, fossil fuel is replaced by fossil-free electricity, which energy is converted and stored in a thermal storage. This makes the process emission- free and reduces the carbon footprint of Herkkumaa’s production to zero. The emissions generated during the manufacturing of the Elstor system are compensated by using the solution for half a year.
Predictability makes pricing easier – which is also visible to consumers
The sharp increase in the price of oil can be seen in the food industry. Abandoning fossil fuels is not only ecological but also a matter of cost.
– Fluctuations in the price of fossil fuels have made it difficult to predict production costs. Tying production to fossil-free energy sources reduces price fluctuations and facilitates pricing, which is ultimately reflected in consumers’ wallets. The future solution is designed so that availability and pricing of raw materials will not be a problem, Rekola continues.
Emission reductions and responsibility are of interest to both consumers and business customers. A small carbon footprint is also a selling point in the export market.
A new type of solution stores electricity cost-effectively as thermal energy
Industry needs steam. Steam is usually produced with fossil fuels, as there has not been a cost-effective alternative in the past. The current energy political situation has greatly accelerated the interest in thermal batteries.
– Our solution stores electricity as thermal energy, from which it is efficiently used to produce heat and steam. We are very pleased that Herkkumaa is the first to use our 10 MWh scale solution in its own production. They look holistically at the future, invest in the green transition and future competitiveness by investing in our cooperation without hesitance, says Kari Suninen, CEO of Elstor. The CO2 reduction of a thermal storage of this size corresponds to the emissions of about 700 passenger cars, continues Suninen.
Herkkumaa and Elstor’s innovative project received Business Finland’s investment support for improving energy efficiency and new technology, which covers about a third of the investment.
