Spain’s Repsol adding renewable hydrogen production at Petronor refinery
Repsol SA is investing €8.9 million to build an electrolyser for production of renewable hydrogen at its majority owned Petróleos del Norte SA’s (Petronor) 220,000-b/d Bilbao refinery in Múskiz, Abanto-Zierbena, in northern Spain’s autonomous Basque Country.
Alongside providing renewable hydrogen for the refinery, the 2.5-Mw electrolyser – which is scheduled for start-up in second-half 2022—will supply other nearby businesses in the Ezkerraldea-Meatzaldea Technology Park (EMTP) of Abanto-Zierbena municipality as part of the first-phase development of Basque Hydrogen Corridor (BH2C), a joint initiative launched by Petronor and Repsol to decarbonize the region’s energy, industrial, residential, and transportation sectors, Repsol and Petronor said in separate releases on the 20th and 21st September.
To be engineered and built by SENER Engineering Group and John Cockerill, the Bilbao refinery’s planned electrolyser will produce renewable hydrogen using renewable electricity to separate water molecules into hydrogen and oxygen based on a process and sources entirely free of carbon-dioxide emissions.
Nortegas Energía Distribución SAU will be responsible for development and construction of all pipelines and associated infrastructure required to transport renewable hydrogen production from the refinery to the EMTP, Repsol and Petronor confirmed.
BH2C
In addition to the Bilbao refinery electrolyser, the BH2C will include two future hydrogen plants requiring electrolysers, according to Petronor and Repsol.
The second plant – to be developed by Petronor, the Basque Energy Agency (EVE), and Enagás for start-up in 2024 in the Port of Bilbao – will host a 10-MW electrolyser for supply of hydrogen to a synthetic fuel production plant to be built by Petronor, Repsol, Saudi Aramco, EVE, and Enagás.
A third plant – due for commissioning in 2025 – will host a 100-Mw electrolyser to supply additional renewable hydrogen to help Petronor in its broader decarbonisation process of its operations, as well as meet growing needs of the BH2C, Petronor and Repsol said.
The BH2C consortium currently consists of 80 organisations – including 11 institutions, 13 knowledge centres and business associations, and 56 companies – which have committed to invest €1,431 million to 2026 on 40 projects across the hydrogen value chain to transform the region into an international renewable hydrogen hub to accelerate sof as well economic recovery of Basque Country and Spain as a whole.
Repsol’s carbon neutrality path
Investments in renewable hydrogen form a core pillar of Repsol’s broader strategy to decarbonise processes at all its industrial complexes as part of the company’s goal to achieve carbon neutrality by 2050 in accordance with the Paris Agreement.
In addition to a building a proposed renewable hydrogen plant with a 100-Mw electrolyser at its 220,000-b/d Cartagena refinery in the Spain’s south-eastern province of Murcia, Repsol said it is working with partner Enagás to scale up development of the collaborators’ proprietary renewable hydrogen production technology based on photo-electrocatalysis for proposed construction of a larger pilot plant at the operator’s 150,000-b/d Puertollano refinery in Spain’s province of Ciudad Real, Castile-La Mancha.
With an aim of leading the Iberian Peninsula’s renewable hydrogen market, Repsol said it plans to install 557 Mw of capacity by 2025 and 1.9 GW by 2030 via installation of new electrolysers at its industrial complexes or conversion of conventional existing units to production of renewable hydrogen using a feedstock of biogas.
