In the German port of Norddeich, the EU HYPOBATT project demonstrates a modular system for high-power charging of electric ships.

The energy transition in maritime transport increasingly involves the electrification of coastal fleets. A concrete signal comes from Norddeich, on the coast of North Sea in Germany, where is the European project HYPOBATT recently successfully demonstrated a modular multi-megaWatt charging system for fully electric vessels.

The demonstration, which took place on February 18, 2026, marks a significant step towards zero-emission ports and decarbonized shipping routes. The test was conducted under real-world operating conditions using the electric ferry. Friesland E-1, considered the first fully electric seagoing ferry designed for open sea operations.

The HYPOBATT project involves 18 partner from 10 European countries, including Spain, Germany, the Netherlands, Belgium, Italy, France, Greece, Poland, the United Kingdom, and Turkey. The consortium brings together companies, research centers, and universities with expertise in the energy, naval, and port infrastructure sectors.

Among the main partners are: IKERLAN (Spain), coordinator of the initiative, RINA (Italia) Damen Shipyards Group (Netherlands), Stemmann-Technik (Germany), Commissariat à l'énergie atomique et aux énergies alternatives (France), University of Strathclyde (UK) and Reederei Norden-Frisia (Germany), which provided the operational context for the ferry trials between Norddeich e Norderney.
This multidisciplinary partnership integrates engineering, scientific, and operational expertise to develop high-power charging systems for electric vessels.

From applied research to operational experimentation at sea

The project HYPOBATT, acronym for “HYper POwered vessel BATTery charging system”, was created with the aim of addressing one of the main technological challenges of maritime electrification: providing extremely high power levels in charging times compatible with port operations.

Unlike the automotive sector, where fast charging is now widespread, the naval sector requires much more complex infrastructure. Ferries and passenger ships use significantly larger batteries than road vehicles and must recharge during short port stops to maintain service continuity.

For this reason HYPOBATT has developed a modular and scalable system of multi-megaWatt charging, designed to ensure high reliability even in marine environments characterised by severe weather conditions, high humidity and high salinity.

In the port of Norddeich, dedicated mechanical and electrical infrastructure was installed at the beginning of the 2026 and subjected to a phase of progressive testing before the final demonstration. The system was designed according to interoperable standards, with the aim of promoting future diffusion on a European scale.

During the final event, the ferry Friesland E-1 of the shipping company North Frisia It served as a test platform to verify the technology's performance under real-world operating conditions. The results, according to the project partners, confirmed the stability and reliability of the high-power charging system.

“This demonstration represents a milestone for the project and for the entire consortium,”

the project coordinator declared Endika Bilbao Muruaga.

“It demonstrates that the technologies developed are not only theoretically sound, but can be successfully implemented in a real maritime environment.”

Port infrastructure as a key to decarbonisation

The innovation developed in the project HYPOBATT It is part of a broader transformation of the European maritime sector. According to numerous industry analyses, the decarbonization of coastal routes and ferry services represents one of the areas where electrification can be most rapidly adopted.

Many ferries operate on short, regular routes, with predictable timetables and frequent port stops: conditions that make the use of battery-powered systems technically more manageable.

However, the large-scale spread of electric ships requires a parallel evolution of the port infrastructuresCharging a single ship can require power comparable to that of small urban electrical substations, with significant impacts on the management of the local energy grid.

In this context, multi-megaWatt systems represent one of the key technologies enabling the industrial adoption of electric power in the maritime sector. The modular approach developed by HYPOBATT aims to reduce installation costs and facilitate integration with existing port infrastructure.

In parallel, the project also worked on operational models and shared technical standards, a crucial element in avoiding technological fragmentation among ports and operators. According to industry analysts, the lack of interoperable standards could significantly slow the spread of electric solutions in maritime transport.

The standardization of charging interfaces, similar to what has happened in the automotive sector, therefore represents one of the fundamental steps in creating a sustainable industrial ecosystem.

European cooperation and 360-degree industrial innovation

With a pilot plant total budget of over 9 million euros, of which approx 6,6 million from European fundsHYPOBATT is among the projects that aim to transform technological research into scalable industrial solutions.

The consortium brings together complementary expertise from shipyards, port operators, technology companies, and research institutions. This collaborative model reflects an increasingly widespread approach in European innovation programs: addressing complex technological challenges through transnational research and industry ecosystems.

According to industry researchers involved in European sustainable mobility programs, the transition to low-emission shipping will require a combination of technologies: electrification, alternative fuels, and the digitalization of port operations.

In this scenario, the solutions of ultra-high power charging They represent a fundamental element for short-sea routes and coastal passenger traffic. Several European ports are already exploring similar pilot projects, particularly in Scandinavian countries and in North Sea, where environmental policies have accelerated the testing of electric ferries.

The experience of Norddeich It demonstrates how European-funded research can help reduce the gap between technological development and operational application, an often critical step in industrial innovation processes.

Towards a new generation of energy-integrated ports

The final demonstration of the project HYPOBATT It does not represent a point of arrival, but rather a passage towards the commercial diffusion of these technologies.
According to several market analyses, in the next few years the European ports They could evolve towards integrated energy hub models, where charging infrastructure, renewable energy production and digital grid management systems operate in a coordinated manner.

In this context, multi-megaWatt charging for electric ships could become a structural component of port infrastructure, similar to what is happening with ultra-fast charging stations in the automotive sector.

The experience gained in the project HYPOBATT shows that the technology is now sufficiently mature to be tested under real-world operating conditions. The next challenge concerns the economic scalability and infrastructure, which will depend on port investments, decarbonisation policies and collaboration between energy operators and shipowners.
