Sustainable energy storage from our forests

  1. Our Vision
  2. The Challenge
  3. Our Solution


The goal? A cost efficient, safe and environmentally friendly solution for large-scale energy storage that promotes a global accelerated shift towards fossil-free energy production.


Affordable energy

Environment friendly

Made from forest

Vastly scalable

Sustainable supply throughout the lifecycle


The world is boiling. It requires a fast transition towards fossil-free sources. Production of electricity must match the demand, which gives poor utilization of capacity. Since 2015, electricity from renewable sources has been cheaper than from fossil fuels. Green, large-scale and cost-effective storage of electricity is a prerequisite for the transition to a society free from fossil energy.


It’s fundamental: Circular economy. We make batteries from forest materials based on organic electronic polymers and biopolymers, which are used throughout the lifetime of the energy storage and then recycled and burned as biofuel. Thereby we maximize the utilisation of materials, enable fossil-free energy production and minimize the overall negative lifecycle impact.

Circular economy makes it possible

Large scale stationary energy storage

Ligna Energy products address stationary storage with a turnover rate below two weeks.

This includes for example residential solar energy storage and car charging stations. It also includes various grid applications, for example for frequency control, solar field storage and wind energy storage.
