Yara Clean Ammonia and Cepsa seal an alliance to connect southern and northern Europe with clean hydrogen

Yara Clean Ammonia and Cepsa have agreed on a strategic partnership to set up the first clean hydrogen maritime corridor between the ports of Algeciras and Rotterdam for the decarbonisation of European industry and maritime transport.

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,” said Magnus Krogh Ankarstrand, President of Yara Clean Ammonia. “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.”

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 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 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,” said Maarten Wetselaar, CEO of Cepsa. “Green hydrogen and its derivatives are the fastest, most viable and competitive solution to accelerate the energy transition in heavy transport and ensure energy independence in Europe.

“The agreements announced, give our project crucial access to markets, customers and distribution infrastructure: three key elements to unlock the potential of our Hydrogen valley. This is major news for the decarbonisation of the European shipping industry and for the planet.”

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 realising 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.

Clean ammonia is one of the most effective alternatives for decarbonising maritime transport. As of 2026, shipping companies are expected to expand the use of this sustainable fuel to reduce CO2 emissions by 100%. 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.

By 2050, clean hydrogen is expected to account for one third of the fuel used in global land transport, 60% of maritime transport and will be instrumental in storing energy from a 100% renewable electricity system.
