ECO STOR is committed to supporting the shift towards a circular economy in everything we do on a local, national and global level.

Local impact

Production of renewable energy is dependent on weather conditions, and inaccurate forecasts of generation from renewable sources on a day-to-day basis lead to unpredictable prices. 

Our battery energy storage systems give more reliable access to energy.

It also represents an opportunity to stabilize fluctuating prices, giving the customer control through charging when prices are at the lowest and discharging the stored energy when prices are high.

National impact

Energy storage allows for the surplus production of renewable energy to be stored, ensuring a more significant share of renewable energy delivers a more significant share of the energy mix, both on a national and an international level.

Energy storage can provide rapid frequency regulation on a grid level, stabilizing the grid more flexibly. Battery energy storage solutions can also act as a reserve during power outages.

The electrification of transportation happening puts new demands on the grid. Utilizing energy storage is a solution that makes it possible to continue this process rapidly without waiting for the much slower and more costly method of expanding the grid.

Global impact

Storage of renewable energy on a global level saves surplus energy from renewable sources, making more renewable energy available in the long run. 

This kind of storage will be necessary to meet the need for renewable energy in a future where electrification of transportation is a fact.

Also, in this future, we see that repurposing batteries from electric vehicles at the end of their first lifecycle into a second lifecycle as energy storage units is a vital step towards using our planet’s resources wisely.


Tonnes of CO2

saved per building by using second-life batteries as energy storage. Energy storage improves the utilization of energy produced by renewable sources, reducing the need to purchase power from other sources.


Kg of CO2/kWh

saved when compared to using new batteries in energy storage. Making new batteries consumes energy and generates CO2 emissions. Repurposing batteries enables storage without increased CO2 emissions.



storage in second-life batteries will be available for energy storage in 2025. If the rest of the world follows Norway´s lead, over the coming decades, this number will surmount to terawatt hours.
