Investment Outlook 

We are currently focusing on team expansion, scaling our sales operations, commissioning storage projects, and developing Power-to-Heat-to-Power (P2H2P) technology. As a result, we are not actively seeking new funding at this time. 

However, we are preparing for an A-round to support our upcoming significant upscaling, both in terms of storage capacity and global market reach. Our future P2H2P capabilities will create opportunities for large-scale impact on greener electricity and heat. We anticipate launching the A-round by early 2026. 

Invest in a Sustainable Future

Innovative energy storage solutions

Founded in 2018, Polar Night Energy is a pioneer in high-temperature thermal energy storage, known for our cutting-edge Sand Batteries. As the global demand for large-scale energy storage surges, driven by the rise of intermittent renewables like wind and solar, our technology is uniquely positioned to meet this need.

Our vision and achievements

We aim to decarbonize energy production and become the global leader in thermal energy storage. Our Sand Battery, which has already been implemented in commercial installations, is designed to store vast amounts of intermittent energy and return it as high-temperature heat. Our next goal is to expand into electricity production.

Investment success and future growth

Polar Night Energy has secured €7.6 million in seed funding, a critical step towards realizing our vision. This funding, led by Jonathan Oppenheimer and supported by Finnish investment firms Stephen Industries, Holdix, Turret, and Swedish family-owned PC Rettig & Co Impact, will drive our growth and innovation.
