Fossil-free industrial heat and steam production

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.
18 %
Industrial process heat production accounts for 18% of Europe’s total energy consumption.
Most of this heat is still produced using fossil fuels.
20 %
A significant share of global greenhouse gas emissions is caused by industrial heat production.
Elstor Oy offers an efficient, clean alternative to fossil fuel-based energy production.

Material-efficient
The materials and components of Elstor’s solution are sourced from readily available raw materials, extremely durable in lifespan, and fully recyclable.

How does it work

Charge using low-cost electricity and use it when needed

Our energy storage system stores electricity during the lowest-cost hours of the day and efficiently converts it into thermal energy. The stored energy is used to produce heat and steam. The system’s operating costs are competitive compared with fossil fuels. In addition to cost savings, the flexible steam production solution protects against market fluctuations.

01

Charging with electricity during the lowest price periods

The charging of the Elstor energy storage system is optimized for the lowest electricity prices of the day. An AI-based charging algorithm automatically selects the required charging hours by monitoring the storage capacity, upcoming electricity prices, and forecast heat demand.
02

Stored in a patented high-temperature energy storage

Thanks to its storage capacity, the lowest electricity prices can be aligned with the heat demand of industrial processes. Optimized charging enables the system’s operating costs to remain lower than those of fossil fuels.
03

Discharged from storage as steam when needed

The charging and discharging processes of the Elstor system are fully independent. This enables flexible heat use to meet the varying needs of industrial processes. The storage discharge rate can be adjusted continuously between 0 and 100%.

System sizes

Larger-scale systems by combining 20 MWh units

A modular solution that scales unlimitedly <40 with multiple units.
