Europe accelerates infrastructure reforms to meet energy transition demands

Europe’s energy transition is increasingly being judged not by ambition alone, but by whether the underlying infrastructure can actually carry it. That was the message emerging from the 12th Energy Infrastructure Forum in Copenhagen on 21-22 May, where EU policymakers, grid operators and industry representatives focused on the practical demands of moving towards a net-zero energy system.

According to the European Commission, the forum underlined the importance of stronger energy networks for a resilient and competitive Europe at a time of geopolitical pressure and volatile gas markets. The discussions placed particular emphasis on two linked priorities: modernising electricity grids and speeding up hydrogen infrastructure deployment.

For industrial decarbonisation players, the significance is clear. Electrification, renewable integration and low-carbon hydrogen all depend on systems that can move power and molecules reliably, cheaply and across borders. The Copenhagen debate reflected a growing recognition in Brussels that the bottleneck is no longer just policy design, but delivery.

One recurring theme was the need to cut through permitting delays. Industry and policymakers alike pointed to slow and fragmented approval processes as a major drag on grid expansion and hydrogen build-out. Speakers at the forum called for simpler procedures, clearer project pipelines and better coordination between national authorities, regulators and system operators. The aim is to shorten development timelines and give investors more confidence that projects can actually reach final investment decision.

Transparency also featured prominently. Reporting on the forum, The Brussels Times said participants highlighted the need for better visibility on where infrastructure is needed, where capacity is constrained and where new projects are most likely to unlock value. Tools that map interconnection capacity and distribution network plans were presented as ways to reduce uncertainty for developers, lenders and potential offtakers.

Hydrogen infrastructure was a central part of the conversation. The forum built on a wider effort already under way in the sector, including a workshop in Brussels on 4 March hosted by ENTSOG and ENNOH on de-risking investment in hydrogen infrastructure. That discussion focused on how to attract private capital during the early market ramp-up phase, when revenues remain uncertain and cross-border projects face particularly high risk.

A joint report published by ENNOH and ENTSOG on 21 May set out practical options to address those barriers. According to the two organisations, the report looks at financing conditions for future hydrogen networks and proposes ways to make large-scale infrastructure investment more bankable as Europe’s hydrogen market develops.

The question of whether to repurpose parts of the existing gas grid or build dedicated hydrogen assets also remained live. Storage, especially in large formations such as salt caverns, was identified as an important part of the picture, particularly if green hydrogen production rises from electrolyser projects linked to wind and solar generation. But speakers also warned that cross-border hydrogen corridors will struggle without aligned tariff rules and a coherent network development strategy.

Electricity grids face a parallel challenge. As renewable generation grows and demand becomes more variable, operators are being pushed to do more with the infrastructure already in place. The forum highlighted digital and operational tools such as dynamic line rating, phase-shifting transformers and network optimisation software, which can increase usable capacity, relieve congestion and delay the need for expensive new builds.

Financing remains a major hurdle. While EU grants, public funding and private lending will all be needed, the forum made clear that the infrastructure gap runs into the hundreds of billions of euros. That has sharpened debate over cost allocation, especially for projects where one country may shoulder the environmental and social burden while neighbouring states capture much of the benefit.

Public acceptance was another issue that could determine whether projects move ahead at all. Developers of power lines and hydrogen corridors continue to face local resistance, and the forum pointed to the need for earlier engagement with communities, clearer explanations of benefits and more visible mitigation measures. In practice, that may mean involving citizens at the planning stage rather than after routes and sites have already been chosen.

The broader policy message from Copenhagen was that Europe already has much of the framework it needs. What it lacks is pace. With the clean energy transition increasingly tied to physical assets rather than aspirations, the pressure is now on member states, regulators and network operators to turn strategy into steel, pipes, cables and operating systems before international competitors gain further ground.
