Topsoe to supply HydroFlex™ technology for Cepsa, Bio-Oils joint-venture renewable diesel, SAF plant in Spain

Updated: Apr 23

Topsoe, a global leader in carbon emission reduction technologies, announced April 16 that it has signed an agreement with Cepsa, a leading international company committed to sustainable mobility.


According to the agreement, Topsoe will provide its HydroFlex™ technology for the production of sustainable aviation fuel (SAF) and renewable diesel at Cepsa’s and Bio-Oils’ new second-generation biofuels plant in Palos de la Frontera, Spain.


The licensing agreement is between Topsoe and Cepsa and represents Topsoe’s first HydroFlex™ order in Spain.


“We are excited to have been selected as the technology provider for this important project,” said Elena Scaltritti, Topsoe’s chief commercial officer. “The demand for SAF and renewable diesel is there, but supply is still lagging behind. Renewable fuels will be absolutely critical to support the energy transition—in particular in sectors such as long-distance transportation that are difficult to electrify. Cepsa delivers a meaningful contribution to decarbonizing the transportation sector, and we’re proud to be working with them.”


The plant, which began construction in February 2024, is expected to flexibly produce 500,000 tons of SAF and renewable diesel annually.


Production is slated to begin in 2026.


With this new plant, Cepsa and Bio-Oils will be doubling their total renewable fuels production capacity to 1 million tons per year and thereby creating one of the largest renewable fuel complexes in Southern Europe.


The production serves to address the rapidly growing demand for SAF.


As cited by the International Energy Agency’s “Net Zero Scenario,” over 10 percent of fuel consumption in aviation needs to be SAF by 2030 to stay on course for net-zero CO2 emissions by 2050.


In 2022, the International Air Transport Association estimated global SAF production to make up only around 0.1 percent to 0.15 percent of total jet-fuel demand.


“This new second-generation plant is central to our ‘Positive Motion’ strategy and will set the European benchmark in the field of green molecules, directly supporting the rapid decarbonization of sectors that cannot run on electrons, like aviation,” said José Manuel Martínez, Cepsa’s director of technology, projects and services. “The new facility will emit 75 percent less CO2 than a traditional biofuel plant and is designed to achieve net-zero emissions in the medium term. In Topsoe we have identified an outstanding partner, with proven technology and a track record of successfully delivering on its promises. We look forward to progressing construction to significantly increase production of this key renewable fuel.”


With HydroFlex™, customers can convert various fats, oils and greases into drop-in renewable jet and diesel that meet all globally accepted specifications for these fuels.


Topsoe’s HydroFlex™ can be deployed in both grassroots units and revamps for coprocessing or fully renewable applications.
