Norway-based maritime technology company Nereida Energy AS (Nereida) has raised NOK 32 million from a group of renowned Norwegian investors, including Grieg, Eviny, Nysnø and Nye Aasen through a private placement of shares.
Nereida offers battery solutions for a broad range of vessels, from service vessels and wellboats to ferries and offshore vessels. Its offering includes a proprietary control system and software platform that forms a distinct layer on top of the maritime battery systems. In addition, the company has developed a flexible module that allows battery strings to be configured at different heights for optimal use of the battery room. The system is also prepared for new chemistries and cell formats.
“Batteries are increasingly becoming commoditized, so it is the management and control system that truly differentiates solutions and determines how much value you get out of the batteries. In practice, we develop the brain and nervous system of the battery systems and deliver this as a turnkey solution, in line with maritime regulations, to shipowners, shipyards and vessel designers,” says Geir Bjørkeli, CEO of Nereida Energy AS.
Nereida’s system ensures safe, stable and efficient use of stored energy by continuously monitoring battery condition, managing data collection and processing, optimising the operation of the vessel’s battery system, and safeguarding both operational safety and cybersecurity.

NOK 32 Million in Growth Capital
Nereida was established last year by a team of industry specialists with several decades of experience in developing and implementing maritime electrification solutions. The company now welcomes a group of strong industrial and financial investors, including Grieg, Nysnø, Eviny and Nye Aasen, who become shareholders through a NOK 32 million private placement. Nereida’s Chair, Hogne Tyssøy, also invests through his private investment company. No further details have been disclosed about the transaction.
The growth capital will be applied to strengthen the organization, further develop Nereida’s battery and energy storage solutions, and support targeted strategic initiatives aimed at enhancing the company’s product platform.
“We are very pleased to bring on board such a group of competent, long-term investors. In addition to providing capital, they also offer strategic support and access to strong industrial ecosystems. We are seeing significant market interest, and these funds enable us to capitalize on these opportunities,” adds Bjørkeli.
Growing Market
Grieg Maritime Group, through its subsidiary Grieg New Energy, is among the investors joining Nereida’s shareholder base.
“Nereida combines strong industrial expertise with a scalable and competitive technology platform. The company is well positioned in a market that is expected to grow significantly in the coming years, driven by increased electrification and stricter climate requirements in the maritime sector,” says Vidar Lundberg, managing director of Grieg New Energy.
According to DNV’s Maritime Forecast to 2050, the deployment of maritime electrification solutions is expected to accelerate significantly in the coming years, with the fleet of vessels using alternative energy solutions – including battery and hybrid systems – projected to nearly double from 2024 to 2028 based on the current orderbook. At the same time, DNV emphasizes that this marks the beginning of a long-term structural shift, where electrification, energy efficiency and low-emission solutions will play an increasingly important role, driven by both regulation and the need for emissions reductions.
Nereida is headquartered in Bergen, with additional offices in Fosnavåg and Oslo, Norway.
