From Spain to Cabo Verde, the EIB is building a global marine decarbonisation plan.
When the European Investment Bank (EIB) signed a loan of 80 million euros to the Port Authority of Bilbao in late 2024, many observers saw it as routine. It was anything.
The center brought together the three priorities that now define the maritime bank's strategy: energy expansion, grid electrification, and renewable energy generation in the port world. In the last 18 months, working through the main European window and EIB Global, the bank has used or committed more than 400 million euros in offshore financing, the most active period of EIB's offshore involvement in a generation.
Bilbao's loan and Málaga's subsequent package form the backbone of the European push. The €80 million Bilbao facility is financing the expansion of water, an underground electricity grid, and renewable generation, positioning the port in the Atlantic Corridor of the Trans-European Transport Network (TEN-T) as a low-carbon alternative to road infrastructure. Málaga's 50 million euro loan, signed in the spring of 2025, follows a similar template in the Mediterranean Corridor: a new multi-purpose area, full electrification of docked ships, and improved border and passenger facilities.
Regulatory Revolution
Both offshore power supply (OPS)—which enables ships to cut auxiliary engines at berth—anticipate FuelEU Maritime, an EU law that mandates OPS in designated EU ports from 2030.
However, the Cabo Verde Blue Economy Sustainable Ports Facility remains the EIB's most ambitious foreign maritime bet in recent memory.
Raised in stages over the past two years, the plan includes 114 million euros in EIB loans and 34 million EU investment grants for a total 148 million concession package under the Global Gateway, the EU's sustainable infrastructure investment strategy. This project includes three of the four maritime areas that cross the Cape Verde archipelago: Porto Grande of Mindelo (fresh water flows, expanded infrastructure for containers and fishing facilities), Palmeira on Sal (accommodation of large vessels, improved fish landing areas), and Porto Novo of Santo Antão (improvement of inter-island communication).
Solar power systems across many ports aim to reduce diesel dependency. The core of this project is the rehabilitation of CABNAVE, which is the only shipyard in Cape Verde. The EIB aims to develop it into a regional maritime center of excellence: a goal that has national resonance, given China's long-term interest in the center. SUBHED
A series of deals is coming into full focus as it coincides with regulatory change taking place in parallel in the EU. FuelEU Maritime, active since the beginning of last year, mandates a continuous reduction of greenhouse gas emissions of ships of more than 5,000 tonnes worth in EU ports: 2% compared to the 2020 base now, rising to 6% in 2030 and 80% in 2050. companies must provide subsidies of 40% of guaranteed emissions from 2024, 70% from 2025, and 100% from 2026.
This double pressure—fuel price versus carbon price—is a commercial profit structure that the EIB's port electrification investment is designed to take advantage of. The bank is risking port authority regulatory changes that may be delayed while we wait for final implementing regulations. Additionally, integrating electrification, renewables, and energy expansion into one loan instrument is more complex than the EIB's previous methods of generating port loans, which were small and considered non-strategic.
€100 Million Funding Gap
But the EIB is not the only big supporter of the energy revolution, and it will never be.
Last year, the European Investment Fund approved the investment of an infrastructure fund that clearly targets the decarbonization of the transport sector, indicating a move beyond pure debt to equity instruments and equity that aims to fill pension funds and insurers with an unaffordable level of individual EIB loans. The European Commission has estimated that a full sea energy revolution will require around 100 billion euros by 2035; the EIF fund route is considered the most sensible way to raise money at that rate.
However, there are still gaps. The portfolio is still heavily weighted towards port-side infrastructure rather than ships themselves; direct EIB financing for ship replacement and other new fuel structures is yet to be implemented on a large scale. The deployment of OPS in all TEN-T ports by 2030 is a bigger task than the two Spanish loans could face. And the political role the bank has taken in Cape Verde raises questions about institutional authority and power that extend beyond the mid-Atlantic.
The EIB offshore schemes of the past 18 months are not isolated transactions; they are a strategic framework. Whether the bank has the resources and political support to match the scale of change it is trying to finance is an open question.
