Market Testing Confirms Demand for 87% of Nordic-Baltic Hydrogen Corridor Capacity
The market testing survey for the Nordic-Baltic Hydrogen Corridor is in, and the signal is hard to ignore: indicated demand covers 87% of the pipeline's planned capacity by 2040. We look at what 93 responses from 81 companies mean for Latvia's 270–300 km section, the Baltic production outlook, and the investment decisions still ahead.

Every pipeline project eventually faces the same blunt question: will anyone actually use it? The Nordic-Baltic Hydrogen Corridor — a planned 2,500-kilometre hydrogen transmission route running from Finland through Estonia, Latvia, Lithuania and Poland to Germany — now has its first substantive answer. The international market testing survey has been completed, and according to Conexus Baltic Grid, Latvia's unified natural gas transmission and storage operator, the response points one way: market participants have indicated demand for the overwhelming majority of the capacity the corridor is being designed to carry.
The market has answered: 79 of 91 terawatt-hours
The numbers deserve a close look. The survey collected 93 responses from 81 companies, together representing 108 hydrogen production, consumption, storage and transportation projects along the corridor's route — Latvian market players among them. Taken together, participants' projections indicate demand for hydrogen transmission capacity of up to 79 TWh per year by 2040. That is approximately 87% of the corridor's theoretical capacity of 91 TWh per year, as estimated in the pre-feasibility study.
"The applications received and the indicated hydrogen production and consumption volumes confirm that the market sees a clear need for this cross-border connection," says Uldis Bariss, Chairman of the Management Board of Conexus Baltic Grid. The next step, he notes, is to further refine capacity needs and assess how ready market participants are to engage in the project's continued development.
An honest caveat belongs here: these are indications of interest, not binding capacity bookings. Market testing measures appetite, not contracts. But an 87% coverage signal at this stage of a project's life is precisely what infrastructure planners — and the financiers behind them — need to see before serious capital gets committed.
Latvia's 270–300 kilometres, built along infrastructure we already trust
In Latvia, the planned section of the corridor would run approximately 270–300 kilometres, developed alongside the existing natural gas transmission pipeline. That routing decision matters more than it might first appear. Following an established energy corridor shortens permitting, limits land-use conflict and keeps construction costs disciplined — lessons European infrastructure projects have learned the hard way over the past decade.
It also plays directly to Latvia's institutional strengths. Conexus operates both the national transmission grid and the Inčukalns underground gas storage facility, so decades of experience managing cross-border flows and seasonal balancing sit within a single operator. The fact that Latvian companies took part in the survey confirms the corridor is being read locally as a market opportunity — not merely a pipe passing through on its way to Germany.
From transit territory to market player
The survey's regional picture is where the story gets interesting for the Baltics. Hydrogen production across the three Baltic States is forecast to grow from 3.4 TWh in 2033 to 11.1 TWh in 2050, while regional consumption rises from 0.2 TWh to 4.5 TWh over the same period. Read those two curves together and the conclusion is clear: the Baltics are positioned to produce roughly twice what they consume by mid-century, with the surplus flowing toward the corridor's major demand centres.
Finland is expected to deliver substantial production growth at the northern end, while Poland and Germany anchor the demand side with significant industrial consumption. For a region that has spent recent years methodically cutting its energy dependence on imported fossil fuels, becoming a net exporter of renewable energy — in molecule form — would complete a remarkable arc.
Flows that sketch a genuinely European hydrogen market
Transporters and traders responding to the survey indicated that cross-border transportation volumes could increase from 25.4 TWh in 2035 to 38.2 TWh in 2050. One detail stands out: the final destination of part of those planned volumes has not yet been determined. Conexus reads this as a sign of a flexible, interconnected European hydrogen market taking shape — trading patterns forming around price and availability rather than rigid point-to-point deals, much as the European gas market matured a generation ago.
The EU shares that reading. The corridor holds Project of Common Interest status, and its study phase has received €6.8 million in co-financing from the Connecting Europe Facility to support detailed technical, economic, regulatory and environmental assessments.
The timeline: studies by 2027, construction around 2029
The project is currently in its feasibility assessment phase, with technical, commercial, regulatory and environmental studies expected to be completed by 2027. On current estimates, construction could begin around 2029, with commissioning of the infrastructure planned after 2033. The corridor is carried by the region's gas transmission system operators — Elering (Estonia), Conexus Baltic Grid (Latvia), Amber Grid (Lithuania), GAZ-SYSTEM (Poland) and ONTRAS (Germany) — together with Gasgrid Vetyverkot, a subsidiary of Finland's gas transmission operator Gasgrid.
By infrastructure standards, that is a brisk schedule. It means the window in which Baltic producers, offtakers and investors can shape the corridor's final configuration is open now — and it runs through the 2027 study deadline, not beyond it.
Young markets need stable rules
The survey results also confirm what most in the sector already sense: the hydrogen market remains at an early stage of development. Conexus is explicit that a stable regulatory environment and effective risk-mitigation mechanisms will be essential to support timely investment decisions. Demand indications alone do not finance pipelines — bankable offtake agreements, predictable tariff frameworks and credible support schemes do. Nothing here is settled, and the distance between an expression of interest and a final investment decision is where most infrastructure projects are won or lost.
What this signals for Baltic hydrogen ecosystem stakeholders
The corridor now has what most early-stage hydrogen infrastructure in Europe still lacks: a quantified, market-sourced demand signal. For Baltic hydrogen ecosystem stakeholders, that changes the planning conversation. Producers weighing electrolyser projects can point to a credible export route; industrial offtakers can start pricing pipeline hydrogen into their decarbonisation scenarios; and policymakers have a concrete case for the regulatory stability the market is asking for. The next round of capacity refinement will separate the committed from the curious — and the time to be in that room is now.
