REOLUM, a Spanish company specializing in innovative solutions for decarbonization and the energy transition, has awarded a consortium led by Técnicas Reunidas and Siemens Energy the front-end engineering design (FEED) contract for the La Robla Green project. This initiative aims to develop one of Europe’s largest renewable methanol plants in La Robla, located in Spain’s León province.
The facility, with a production capacity of 140,000 tons per year, will combine biogenic carbon from a biomass cogeneration plant with renewable hydrogen to produce e-methanol.
At the forefront of e-methanol production technologies, this project will contribute significantly to the decarbonization of maritime transport—both as a direct fuel and as a key raw material for sustainable aviation fuel (SAF). Additionally, methanol produced from low-emission feedstocks is crucial in reducing emissions from high-carbon industries such as chemicals, aviation, and shipping.
The project brings together the expertise of five industry leaders in decarbonization: Reolum, Siemens Energy, Mitsubishi Heavy Industries, Ltd., Johnson Matthey, and Técnicas Reunidas.
Under the contract’s scope, Siemens Energy will focus on the renewable hydrogen unit, while Técnicas Reunidas will oversee the biogenic carbon capture and e-methanol production units. Mitsubishi Heavy Industries will act as the CO₂ capture licensor, and Johnson Matthey will supply its proprietary eMERALD™ technology, enabling the direct hydrogenation of captured CO₂ into methanol.
This initiative aligns with Técnicas Reunidas’ track strategy for decarbonization, which is a key pillar of SALTA, the company’s strategic program launched in May 2024.
The completion of this engineering phase will pave the way for the plant’s full-scale execution under an EPC (engineering, procurement, and construction) contract.
On February 21, 2025, Spain’s Ministry for Ecological Transition and the Demographic Challenge allocated €180 million from NextGenerationEU funds to the project. This funding is part of the H2 Valles Program, which aims to establish seven major renewable hydrogen clusters across Aragon, Andalusia, Castile and León, Catalonia, and Galicia.
