Grieg New Energy joins a strong investor group entering the shareholder side of Nereida Energy AS through a NOK 32 million share issue.
Nereida offers battery solutions for a broad range of vessels, from service vessels and wellboats to ferries and offshore vessels, with a proprietary control system and software platform that provides a unique layer on top of the battery systems.
“Batteries have gradually become off-the-shelf products, so it is through the control and management system itself that the greatest efficiency gains can be achieved. In practice, we are developing the brain and nervous system of the battery packs and delivering this as a complete solution, in line with maritime requirements, to shipowners, yards, and ship designers,” says Geir Bjørkeli, CEO of Nereida Energy AS.
Nereida’s system ensures the safe, stable, and efficient use of stored energy by continuously monitoring battery condition, handling data collection and processing, optimising the vessel’s battery system’s operation, and safeguarding both operational safety and cybersecurity.
Nereida was established last year by a group of industry specialists with several decades of experience in developing and implementing maritime electrification solutions. A group of strong industrial and financial investors, including Grieg New Energy, Nysnø, Eviny, and Westfal-Larsen, is now entering the company’s shareholder base through a NOK 32 million private placement.
Nereida’s chair, Hogne Tyssøy, is also investing through his private investment company. The parties have not disclosed further financial details of the transaction.
The growth capital will be used to strengthen the organisation, further develop Nereida’s battery and energy storage solutions, and support targeted strategic initiatives to strengthen the company’s product platform.
Grieg New Energy, part of the Grieg Maritime Group, is among the investors now joining Nereida’s shareholder base.
“Nereida combines solid industrial experience 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, CEO of Grieg New Energy.
According to DNV’s Maritime Forecast to 2050, the rollout of maritime electrification solutions is expected to accelerate significantly in the years ahead. The fleet of vessels using alternative energy solutions, including battery and hybrid solutions, is estimated to nearly double from 2024 to 2028 based on today’s order intake. At the same time, DNV emphasises that this is the beginning of a long-term structural shift in which electrification, energy efficiency, and low-emission solutions will together play an increasingly important role, driven by both regulation and the need to cut emissions.
“For us, this is an investment with clear commercial potential and an important contribution to the development of more energy-efficient and sustainable maritime operations globally,” adds Vidar Lundberg.
Nereida is headquartered in Bergen, with additional offices in Fosnavåg and Oslo.
Grieg New Energy AS is part of Grieg Maritime Group and invests in sustainable energy solutions and companies that contribute to the green transition. The modern maritime group is part of the Grieg Group and can trace its history back to Joachim Grieg, who established a shipbroking firm in Bergen in 1884.
Nysnø Klimainvesteringer AS is the Norwegian state’s climate investment company. Established in 2017, it invests in companies and funds that contribute to reduced greenhouse gas emissions and the transition to a low-emission society.
Eviny is investing through the group’s venture arm, Eviny Ventures AS, which invests in early-stage and growth-stage companies within energy, technology, and electrification, with a focus on solutions that contribute to the green transition. Eviny was established as Bergenshalvøens Kommunale Kraftselskap in 1920 and is today among Norway’s largest energy and technology groups.
Westfal-Larsen is investing through the investment company Nye Aasen AS, which is controlled by Helene Westfal-Larsen and her siblings. Westfal-Larsen is one of Bergen’s most important maritime family businesses and has played a central role in the city’s shipping history since the shipping company was founded in 1905.
