Norway-headed Yara Clean Ammonia, part of global ammonia and fertilizers major Yara International ASA (Yara), and Spain-headed multi-energy major Compañía Española de Petróleos, S.A.U. (Cepsa), a Mubadala Group company, have agreed on a strategic partnership to set up the first clean hydrogen maritime corridor between the Port of Algeciras in Spain and the Port of Rotterdam, the Netherlands for the decarbonization of European industry and maritime transport.

Yara Clean Ammonia operates the largest global ammonia network with 15 ships and access to 18 ammonia terminals and multiple ammonia production and consumption sites across the world, through Yara International.
The partnership envisages Yara Clean Ammonia (YCA) supplying Cepsa with clean ammonia volumes, which will allow the energy company to get a head start in establishing the clean hydrogen corridor and lead the initiative to serve industrial and maritime customers in Rotterdam and Central Europe.
Yara Clean Ammonia and Cepsa have forged a pioneering partnership to establish a credible and robust supply chain for clean energy transformation in Europe. This partnership will lay a solid foundation for industrial efforts to secure clean ammonia and hydrogen for several downstream applications in Europe while securing the clean transformation goals. We are delighted to be a part of this collaborative initiative, said Magnus Krogh Ankarstrand, President of Yara Clean Ammonia.
Robust supply chain
The alliance with Yara Clean Ammonia will help establish a safe, resilient, and cost-efficient supply chain for delivering clean ammonia to Cepsa’s industrial and maritime customers in Rotterdam, the Netherlands, and Central Europe.
The partnership also paves the way for Cepsa to deliver the first clean hydrogen molecules to its customers by using Yara Clean Ammonia’s global supply base and logistical footprint.
This will in turn allow the energy company to start marketing clean hydrogen and clean ammonia to industrial customers and maritime customers in Rotterdam and Central Europe.
Today’s agreements are a crucial step towards the long-term viability of the Andalusian Green Hydrogen Valley and the implementation of the first maritime corridor of sustainable fuels that will link the South with the North of Europe. Green hydrogen and its derivatives are the fastest, most viable, and most competitive solution to accelerate the energy transition in heavy transport and ensure energy independence in Europe. The agreements announced today give our project crucial access to markets, customers, and distribution infrastructure: three key elements to unlocking the potential of our Hydrogen Valley. This is major news for the decarbonization of European shipping and industry and for the planet, said Maarten Wetselaar, CEO of Cepsa.
Uniting Europe with a clean hydrogen corridor
The alliance incorporates Yara Clean Ammonia as the newest partner of the Andalusian Green Hydrogen Valley. YCA and Cepsa will work comprehensively to develop a robust supply chain for realizing the clean hydrogen corridor.
Cepsa will build a new green ammonia plant at its energy park in San Roque, Cádiz, near the Port of Algeciras, with an annual production capacity of up to 750 000 tonnes.
Yara Clean Ammonia has its largest ammonia and fertilizer plant in the Netherlands. Since 1929, the Dutch Yara site has been located in Sluiskil on the Ghent-Terneuzen canal, a major deep-sea waterway opening into the North Sea and connecting European inland rivers and railways all over Europe.
Said to be the largest fertilizer production site in Western Europe, it is highly integrated and is one of the world’s most efficient plants.
A sustainable fuel for shipping and a hydrogen carrier
According to Yara, clean ammonia is one of the most effective alternatives for decarbonizing maritime transport.

As of 2026, shipping companies are expected to expand the use of this sustainable fuel to reduce carbon dioxide (CO2) emissions by 100 percent. Both its production, combining clean hydrogen and nitrogen from the atmosphere, and its use as a fuel are carbon neutral.
In addition, it is easier and more sustainable to transport ammonia than hydrogen as it can be transported at a higher temperature (ammonia is transported at -33°C, while hydrogen needs to be cooled to -253°C).
After being transported, the clean ammonia can be converted back into hydrogen for distribution as will be done in the Port of Rotterdam, where a terminal is being built to perform this conversion and channel the clean hydrogen via pipelines to Germany, Belgium, Denmark, or the Netherlands.
The companies state that “this commitment to sustainable maritime fuels is in line with the European Commission’s Fit for 55 package, which includes “FuelEU Maritime,” a legislative initiative that aims to stimulate demand for sustainable alternative fuels in maritime transport to reduce greenhouse gas (GHG) emission intensity by 2 percent in 2025, 6 percent in 2030, and 75 percent in 2050, compared to 2020 levels.
In addition, the development and use of sustainable fuels contribute to several of the 2030 Agenda’s Sustainable Development Goals: SDG 7 (Affordable and clean energy), SDG 8 (Decent work and economic growth), SDG 12 (Responsible consumption and production), and SDG 13 (Climate action).
By 2050, clean hydrogen is expected to account for one-third of the fuel used in global land transport, and 60 percent of maritime transport and will be instrumental in storing energy from a 100 percent renewable electricity system.
