Renewable Energy –
On demand

Energy storage makes renewable energy plannable

SaltX industrial large-scale energy storage solutions enable a decarbonized and fossil-free future by making renewable energy plannable. Cities and industries must heavily reduce their carbon footprint – we are here to make it happen.

Our solution


Aiming for net-zero energy systems

Renewable energy from solar and wind are becoming the new energy standard worldwide. To empower cities and industries to realize this crucial transition and move away from fossil energy, we need efficient and sustainable energy storage serving several terawatt-hours of capacity. We are willing to take on that challenge.


Sustainable and highly effective energy storage

Large-scale energy storage solutions will play a significant part in the new decarbonized economy. By streamlining capacity needs and making maximum use of all renewable energy resources – new opportunities emerge. SaltX makes unplannable renewable energy plannable with circular, efficient, and sustainable storage solutions.

Technology alone won’t save us

New powerful technology alone isn’t enough. It must be matched with the same innovative thinking on a systemic level: in society, with decision-makers, and in boardrooms of large companies.
