Klaipėda Port's Green Hydrogen Station: A Baltic First That the Region Needed
Klaipėda is about to become the first port in the Baltic States to produce electrolysis-based green hydrogen on-site — and the multi-use setup, covering maritime, road, and public transport, is exactly the kind of proof-of-concept the entire region has been waiting for.

The Milestone That Has Been Years in the Making
Something genuinely significant is happening just across the Gulf of Riga. The Port of Klaipėda — Lithuania's only deep-water port and one of the Baltic Sea's key cargo gateways — has crossed the construction finish line on the region's first green hydrogen production and refuelling station. The site completion certificate has been issued, final equipment installation is wrapping up, and within weeks, the first molecules of electrolysis-based green hydrogen will be produced on Baltic soil.
This is not a feasibility study. It is not a rendered concept on a PowerPoint slide. It is a physical station, at Nemuno Street in the port territory, housing a PEM (Polymer Electrolyte Membrane) electrolyser capable of producing up to 500 kg of green hydrogen per day — around 127 tonnes per year — powered by renewable electricity sources including offshore wind and solar. Full commercial-scale regular production is on track for the first half of 2026.
For everyone watching from the Latvian hydrogen ecosystem, this moment carries real weight.
Why PEM Electrolysis Matters — and Why It Matters Here
Not all hydrogen is created equal, and this distinction is worth spelling out clearly. Green hydrogen — produced by splitting water using renewable electricity in an electrolyser — is the only production pathway that is genuinely zero-carbon from the outset. No steam methane reforming, no carbon capture bolt-ons, no natural gas dependency. Just water, renewable electrons, and oxygen as a byproduct.
The PEM technology selected for Klaipėda is particularly well suited to port and multi-use environments. It responds dynamically to variable renewable power inputs, requires a compact footprint (the production unit fits inside a standard 40-foot marine container), and delivers high-purity hydrogen at the pressures needed for direct vehicle and vessel refuelling. For a port that needs to serve everything from waste-collection vessels to heavy trucks to passenger cars, PEM electrolysis is the right call — flexible, scalable, and modular enough to grow as demand grows.
The Klaipėda electrolyser was manufactured at the IMI Remosa facility in Cagliari, Italy, and has already passed factory testing. When operating at rated capacity, it consumes up to 3 MW of electrical power. The scale is deliberately modest — this is a pilot — but the design principle is scalable: the modular container format means capacity can be stacked as the hydrogen offtake market matures, which is exactly the pragmatic pathway that de-risks the investment logic for future expansion.
A Multi-Use Station — and Why That Is the Right Model for Ports
What sets Klaipėda apart from hydrogen pilots elsewhere in Europe is its deliberate multi-use architecture from day one. The station will not serve a single customer with a single application. It has been designed as open infrastructure for the broader transport and logistics market:
Maritime: A dedicated waste-collection vessel, built specifically to run on hydrogen produced at the port, will be the world's first operational deployment of this type. It will handle waste streams from all ships calling at Klaipėda — a closed-loop, zero-emission port service operation.
Road haulage and logistics: The port authority, together with LTG Group (Lithuanian Railways), Klaipėda cargo company Bega, and Volvo Lietuva, is actively developing use cases for hydrogen-powered heavy trucking and freight logistics. Hydrogen-powered locomotives are also being explored for port shunting and rail connections.
Passenger vehicles: The public hydrogen refuelling station attached to the facility will be open to private car owners and fleet operators. The port authority itself has already acquired a Toyota Mirai fuel cell vehicle as a working demonstration of the technology.
This multi-stakeholder, multi-application model is precisely what makes port environments so valuable as hydrogen pilots. Ports concentrate diverse transport modalities — maritime, road, rail — within a single regulated perimeter, with an institutional operator (the port authority) capable of anchoring demand across all of them. That combination of captive demand, infrastructure control, and operational diversity is very hard to replicate outside a port setting.
Hats Off to Klaipėda Port — This Was Not Easy
It would be too easy to read a headline like "Baltic's first green hydrogen station nears completion" and assume this happened smoothly. It did not.
The Port of Klaipėda Authority navigated every layer of complexity that comes with being a public institution implementing a frontier energy project. Environmental impact assessments. Building permit procedures. EU funding compliance under two separate mechanisms — the 2021–2027 EU Structural Funds and the NextGenerationEU recovery plan. A total project value approaching €12 million, with EU co-financing of around €6 million, means months of tendering, procurement rules, reporting obligations, and audit trails. Add to that the negotiations with Klaipėda municipality, the coordination of multiple commercial partners, the sourcing of specialised electrolyser equipment from Italy, and the challenge of managing public expectations around timelines — and the picture becomes considerably more demanding than it looks from the outside.
Director General Algis Latakas and the entire port authority team set out less than a year ago on what he described as "a completely uncharted path." They are now holding the site completion certificate. That is a meaningful institutional achievement, and it deserves to be named as such. Delivering a first-of-kind infrastructure project on EU public funding, within a statutory port body, with all the procedural obligations that entails — that takes organisational grit and genuine leadership commitment.
Lithuania's Deputy Minister of Transport, Dovilė Sujetaitė, put it plainly: this project is the first and unique fuel production initiative of its kind not only in Lithuania but across the entire Baltic region, and it opens the door to real change — not just for the port, but for the country's entire transport fuel ecosystem.
What This Means for the Baltic Region — and for Latvia
The Port of Klaipėda does not exist in isolation. It sits within a regional logistics system that connects to Riga, Tallinn, Helsinki, and the broader Northern European freight corridor. And it has just demonstrated something that the entire Baltic hydrogen conversation has needed: that a port-based, PEM electrolysis, multi-use green hydrogen project can be built, permitted, funded through EU mechanisms, and delivered by a public port authority operating under real-world constraints.
That is a replication template.
Latvian hydrogen ecosystem stakeholders — port operators, energy project developers, logistics companies, policymakers, and research institutions — now have a living reference case directly on the eastern Baltic coast. The project architecture at Klaipėda — open-access infrastructure, PEM electrolyser in a containerised format, multi-modal refuelling capability, public-private demand pooling — maps naturally onto the conditions at Riga Freeport, Liepāja Port, and Ventspils Port. All three have the institutional structures, the renewable energy connectivity, and the freight diversity to host comparable pilots.
Latvia is already developing its own hydrogen infrastructure. Hydrogen refuelling stations are operational in Riga. Hydrogen-electric trolleybuses are running in daily service. The Liepāja Port green hydrogen production project is in development planning. Latvia hosted the European Hydrogen Valleys Investment Forum in Riga in 2024 and again in 2025, positioning itself as the region's emerging hydrogen hub. The Latvian Hydrogen Association is an active member of Hydrogen Europe. Companies like Naco Technologies, ProtiumTech, Neohytech, and others are building real hydrogen technology capabilities from Latvian soil.
What Klaipėda has now added is proof that the port pilot model works — not just on paper, but through the full cycle of permitting, construction, and commissioning under EU funding rules. That proof matters enormously for the investment and policy case here in Latvia.
Indigenous Fuel Production as Energy Resilience — The Strategic Dimension
There is a dimension to this story that goes beyond clean air and carbon accounting, and it is worth naming directly.
The Baltic States have spent the past three years accelerating their energy independence agenda — synchronising electricity grids with Continental Europe, diversifying gas supply, expanding renewables. Green hydrogen produced locally by electrolysis is a natural extension of that agenda: it converts domestically generated renewable electricity into a storable, transportable transport fuel that requires no imports, no pipeline infrastructure from non-aligned suppliers, and no dependence on global fossil fuel market pricing.
A port that produces its own hydrogen from local wind and solar power is a port that controls its own fuel supply. That matters for maritime operators facing tightening EU shipping decarbonisation requirements under FuelEU Maritime. It matters for logistics companies that need to plan five-year fleet transitions with some certainty about fuel availability. And it matters for the national energy security picture — the more locally produced clean fuel there is in the system, the less exposure there is to the price and supply volatility of imported fossil fuels.
Klaipėda has taken the first step in the Baltic port world. The infrastructure logic, the economic model, and the regulatory pathway are now visible. For Latvian ports and policymakers, the next move is clear.
What Comes Next
Production at Klaipėda is expected to begin within weeks. Over the coming months, the station will move through its commissioning sequence: first hydrogen production, first maritime refuelling of the waste-collection vessel, first road vehicle refuelling. Full regular production is targeted for mid-2026.
The lessons from that commissioning and early operations period — on electrolyser performance, grid interaction, safety protocols, refuelling logistics, and offtake contracting — will be invaluable for the next wave of Baltic port hydrogen projects.
Latvian hydrogen ecosystem stakeholders should be watching closely, and engaging directly. The knowledge transfer opportunity is real, and the window to shape replication on Latvian terms is open now.
