Scaling renewable fuels production
In 2026, Repsol continued to scale its production of renewable fuels with the start of operations at its Puertollano Industrial Complex, where it transformed an existing unit to produce 100% renewable diesel.
Puertollano: transforming existing infrastructure
The new facility, which previously processed fossil-based raw materials, has the capacity to produce 200,000 tons per year of Repsol’s 100% renewable Nexa Diesel from agricultural and food waste. It’s expected to avoid approximately 700,000 tons of CO2 emissions per year, compared to conventional fuels, and taking into account the product’s entire lifecycle.
Repsol invested €130 million in the Puertollano transformation project and an additional €16 million to enable the use of renewable hydrogen at the facility, replacing natural gas with biogas to further reduce emissions.
Demonstrating low-carbon technology at scale
This is Repsol’s second large-scale renewable fuels project, demonstrating the real-world potential for low-carbon technology. Repsol opened its first facility at its Cartagena plant in 2024, capable of producing 250,000 tons of renewable fuels per year.
Renewable fuels for existing vehicles
Repsol’s renewable fuels can be used in current engines and are already available at 1,600 of the company’s service stations, enabling its customers to reduce their carbon footprint without the need for modifications to vehicles or the distribution network.
