Transform your steam process to completely fossil-free

– economically

You read correctly, keep on digging

Industrial steam and heat production processes rely on fossil fuels, resulting in significant carbon dioxide emissions. Industrial process heat production accounts for an 18% share of the entire energy consumption in Europe, with the majority of this production relying on fossil fuels. Elstor offers an efficient and clean alternative to the use of fossil fuels.

89 %
Industrial steam produced with fossil fuels in Finland
Fossil fuels are a depleting natural resource, causing a significant emission burden and cost for the user.
12 TWh
Industrial heat and steam produced with fossil fuels
The poor efficiency and inflexible production of fossil fuels result in additional costs and emissions.
3 Mt
CO2 emissions from industrial process heat and steam production
The emission reduction potential in Finland alone is enormous. Emissions from industrial process heat and steam production account for approximately 7% of Finland’s total emissions.

480–1700 t
carbon dioxide emission reduction with one Elstor basic unit
The emission reduction depends on the capacity, usage, and previously used fuel. Elstor eliminates operational emissions by using clean electrical energy.
95–97 %
Power-to-heat efficiency of Elstor system
Elstor’s device achieves a high efficiency through precisely optimized production and storage charging. Steam production adjusts completely according to the customer’s consumption.
6 months
During operation, Elstor’s device has offset the carbon dioxide emissions resulting from the device’s manufacturing
The CO2 emissions generated during the manufacturing of the device have been offset within approximately six months of use. After this, every saved tonne of CO2 is pure profit.

How does it work

Charge with inexpensive electricity and use it when needed

Our thermal storage solution efficiently stores electricity from the cheapest hours of the day as thermal energy. The stored energy is then used to produce steam. The operating costs of the equipment are competitive with fossil fuels. In addition to cost savings, the flexible steam production solution provides protection against market fluctuations.

01

Charging with electricity during the lowest price periods

Elstor’s energy storage charging is optimized for the lowest electricity prices throughout the day. An artificial intelligence-based charging algorithm automatically selects the required charging hours by monitoring the storage capacity, upcoming electricity prices, and predicted heat demand
02

Stored in a patented high-temperature energy storage

Thanks to the storage capacity, the lowest electricity prices and the heat demand of industrial processes align. Due to optimized charging, the operating costs of Elstor’s device are lower than those using fossil fuels
03

Discharged from storage as steam when needed

Elstor’s device charging and discharging processes are completely independent. This enables flexible use of heat to meet varying needs in industrial processes. The adjustment of the discharge from the storage can be smoothly controlled within the range of 0–100%.

For whom

Real-world tested energy storage for the process industry

Elstor’s energy storage systems have been in use in the process industry since 2021. The operational experiences have been positive both in terms of cost reduction and production flexibility. Elstor’s device is suitable for various industrial sectors due to its flexible steam production.
