ShipTown Secures Strategic Seed Investment to Scale Revolutionary H‑Battery Green Energy Technology
ShipTown, a Danish deep‑tech startup founded in 2023 with a mission to make green energy affordable, reliable and accessible, has secured a strategic seed investment that will enable it to move its patented H‑Battery technology from prototype development toward commercial scaling. The funding round marks a key milestone for the Fredericia‑based company as it transitions from early research and innovation phase into broader industrial deployment and prototype scaling across energy systems such as data centres, PtX (Power‑to‑X) facilities and other critical infrastructure.
ShipTown’s technology, built around a reversible hydrogen battery that combines electrolysis and fuel‑cell functions in a single unit, is designed to store surplus renewable energy and deliver it back as electricity when demand peaks or intermittent generation drops. With total efficiencies of around 90 % in electrolysis and 60 % in fuel‑cell operation, the system promises high performance without rare materials and with simplified modular design, making it well‑suited for large‑scale energy storage and grid‑balancing applications.
In October 2025, ShipTown announced that European Energy — a leading developer in renewables and PtX infrastructure — led a DKK 5 million (~€670,000 / ~$730,000) investment into the company’s scaling efforts. The involvement of European Energy underscores confidence in ShipTown’s ability to translate its breakthrough H‑Battery technology into viable commercial products that support the green energy transition by addressing key storage challenges faced by renewable power producers and large energy users.
Alongside European Energy, green investor Lars Fejer also participated in the financing as a private backer. Fejer, known for his experience in sustainable investment and fund advisory, joined the round after closely following ShipTown’s development over the past year, bringing both capital and strategic insight as the startup accelerates toward industrial validation and market entry.
The funding represents a strategic breakthrough for ShipTown, allowing the company to move beyond smaller innovation grants and accelerator support — such as R&D projects funded by the Danish Board of Business Development and EU‑co‑financed soft funding, participation in the Beyond Beta accelerator and backing from Miljø‑ og Energifonden and Fonden for Retfærdig Omstilling — toward commercial technology scaling with a credible industrial partner.
CEO Marie Vedel has stated that the injection of private capital will enable ShipTown to build next‑generation prototypes, test the H‑Battery at larger scales, and bring the right technical competencies into the team to support ongoing development and commercial deployment. With this funding behind it, the company plans to transition from a small R&D‑focused team into a more robust engineering organisation capable of demonstrating its technology in real‑world settings.
The investment also opens the door for a match‑loan of DKK 3 million from EIFO (Energy Investment Fund of Denmark), which can further strengthen ShipTown’s financial foundation and support additional testing infrastructure in collaboration with European Energy and other partners. This combination of private investment and public‑sector support reflects an ecosystem approach to deep‑tech funding that is increasingly common in European energy innovation.
Industry analysts see ShipTown’s progress as part of a broader trend of green hydrogen and energy‑storage technology funding, where innovative approaches to storing renewable power are attracting both institutional and strategic capital. The H‑Battery’s ability to bridge intermittent generation and demand, while avoiding rare materials and focusing on simple, scalable engineering, positions ShipTown as an intriguing player in the evolving energy storage landscape.
Looking ahead, ShipTown’s roadmap includes building and testing full‑scale pilot modules — with a 2 MW demonstration unit targeted for 2027 — and deepening collaborations with universities, industry partners and testing organisations. The commercial cases under development are expected to not only prove technology performance but also help ShipTown secure its first industrial customers across Denmark and beyond.
ShipTown’s funding journey — from early grants, accelerator programmes and public‑sector support to now securing meaningful private investment — reflects the maturation of its technology and the confidence of strategic investors in its potential to deliver sustainable, grid‑ready energy storage solutions. As the company scales, its leadership has emphasised a long‑term vision of establishing a Danish‑rooted industrial producer of green energy systems capable of competing globally while contributing to decarbonisation goals.
