European Commission approves €1.5 trillion investment in transformative energy infrastructure projects

The European Commission has taken a significant step towards shaping the future of Europe’s energy infrastructure by approving 235 key projects under its latest Projects of Common Interest (PCI) and Projects of Mutual Interest (PMI) programme. This move is poised to accelerate the development of critical cross-border electricity, hydrogen, smart-grid, and carbon transport infrastructure, signalling vast opportunities for technology suppliers, system engineers, and power-electronics developers embedded in Europe’s industrial decarbonisation efforts.

The Commission’s approval grants these projects priority access to EU Connecting Europe Facility (CEF) funding and fast-track permitting procedures, thereby expediting their deployment. The combined projected investment in these initiatives could approach €1.5 trillion by 2040, reflecting unprecedented demand for advanced components such as semiconductor devices, high-voltage direct current (HVDC) transmission equipment, electrolysers, sensors, control systems, and grid-management software.

The comprehensive list includes 113 electricity and smart-grid projects aimed at enabling the integration of greater shares of renewable energy while enhancing cross-border interconnections to bolster grid stability and energy security. Moreover, 100 hydrogen and electrolyser projects focus on facilitating industrial decarbonisation and fostering a cohesive and cleaner European energy system. Complementing these are 17 carbon dioxide transport projects, which play a pivotal role in advancing carbon capture and storage solutions critical for reducing emissions from hard-to-abate sectors. Additionally, three smart gas grid projects and two legacy interconnectors linking Malta and Cyprus to the mainland have also been greenlighted.

Among the highlighted initiatives are projects backed by Italian gas operator Snam, including the SoutH2 Corridor, a hydrogen pipeline connecting Algeria, Italy, Austria, and Germany, and the Callisto offshore CO₂ storage project near Ravenna, Italy. These projects underscore the strategic dimension of the Commission’s infrastructure agenda to leverage Mediterranean energy corridors and strengthen Europe’s carbon management capabilities.

The Commission emphasises that these infrastructures are foundational to the European Green Deal objectives and the Affordable Energy Action Plan, which centres on securing energy accessibility and price stability amidst global challenges. The plan recognises that well-integrated, resilient energy networks are vital for delivering affordable, competitive, and clean energy to households and industries alike.

Teresa Ribera, Executive Vice-President for Clean, Just and Competitive Transition, framed the approval as a crucial milestone: “These projects are more than cross-border infrastructure projects, they are the lifelines of our Energy Union. They empower our EU energy system by unifying the strengths of 27 complementary systems, paving the way for a Europe where green, competitive, and secure energy is not just a promise, but a common reality.”

Her sentiments were echoed by Commissioner for Energy and Housing Dan Jørgensen, who remarked: “Energy infrastructure is not only the backbone of our Energy Union , it is the foundation of a strong and prosperous Europe. To meet today’s challenges of security, competitiveness, and decarbonisation, Europe needs an energy system that is both resilient and future-proof. The projects we have chosen to support will play a vital role in delivering cleaner, cheaper and more secure energy to our citizens and businesses.”

Following European Parliament and Council scrutiny under the TEN-E regulation, set to conclude within a two- to four-month window, the Commission plans to engage deeply with project promoters to ensure their swift buildout. Concurrently, PCI Energy Days discussions will assess project execution and funding pathways, reinforcing momentum within the energy technology supply chain.

The increased focus on grid infrastructure aligns with a package of complementary measures from the European Commission to ease the energy crisis, such as demand reduction targets and revenue capping for low-cost energy producers, and to support a broader Clean Industrial Deal, introduced earlier in 2025, which aims to counteract elevated energy prices while promoting competitiveness and innovation.

Funding mechanisms are already in place to support these priorities, with the Connecting Europe Facility for Energy recently allocating €1.25 billion to 41 cross-border projects, and an additional €600 million call for proposals launched to further underpin cross-border infrastructure developments. Meanwhile, new guidance promotes the accelerated rollout of renewable energy grids and storage solutions, further reducing energy costs while facilitating the transition to low-carbon energy systems.

For the industrial decarbonisation sector, this large-scale infrastructure push represents a critical inflection point. The increased deployment of HVDC transmission links, offshore energy hubs, integrated hydrogen pipelines, and carbon transport routes will demand sophisticated power electronics, advanced sensing technologies, and cutting-edge system controls. Equipment manufacturers, energy technology developers, and engineering firms stand to play central roles as Europe accelerates toward its 2030 and 2050 climate and energy goals. The Commission’s approach confirms that a resilient, interconnected, and future-proof grid is the backbone upon which Europe’s clean energy future will be built.
