Transition Industries LLC has signed a definitive Engineering, Procurement and Construction (EPC) agreement with Siemens Energy and Techint Engineering & Construction (Techint E&C) for the approximately 210 MW electrolyzer facility at its Pacifico Mexinol project in Sinaloa, Mexico. The agreement marks a major development milestone for the projectโs renewable hydrogen production infrastructure, although it remains subject to customary conditions precedent, including the completion of project financing.
The Pacifico Mexinol electrolyzer facility will use Siemens Energyโs Elyzer P-300 technology to produce renewable hydrogen for the production of renewable fuels of non-biological origin (RFNBO). The facility will form part of Pacifico Mexinolโs planned 6,130-metric-ton-per-day ultra-low-carbon methanol complex.
The EPC agreement follows the Front-End Engineering Design (FEED) contract announced in August 2025. It establishes the next phase of collaboration between Transition Industries, Siemens Energy and Techint E&C, moving the project from engineering design towards an integrated delivery framework. Construction is expected to begin in early 2027, subject to the fulfilment of the agreementโs conditions precedent.
Siemens Energy to Supply Elyzer P-300 Technology
The approximately 210 MW installation will use Siemens Energyโs Elyzer P-300 electrolyzer technology to produce renewable hydrogen. This hydrogen will support the production of RFNBO methanol within the wider Pacifico Mexinol development.
โMoving from front-end engineering to a signed EPC agreement is a significant milestone for Pacifico Mexinol,โ said Rommel Gallo, CEO of Transition Industries, the parent company of Pacifico Mexinol. โThis agreement brings together Siemens Energyโs electrolysis technology and Techintโs construction capabilities to deliver a critical component of our project and a landmark for renewable hydrogen in the Americas. It reflects our continued commitment to developing world-scale infrastructure that can meet growing demand for lower-carbon fuels and chemical products.โ
โAt approximately 210 MW, this hydrogen plant would be Siemens Energyโs largest electrolyzer installation in the Americas. The project has the potential to accelerate low-carbon fuel production in the region and advance the global decarbonization of hard-to-abate industries,โ said Dan Restrepo, Head of Electrolyzer Sales Americas.
Techint E&C to Support Project Delivery
The EPC agreement brings together Siemens Energyโs electrolyzer technology and Techint E&Cโs engineering and construction capabilities for the development of the facility. The arrangement is intended to translate the completed engineering design into a framework for project execution.
โWe are pleased to continue supporting Pacifico Mexinol in the development of the Project through our alliance with Siemens Energy. We will execute this work with the highest standards of safety, integrity and transparency, and with respect for the communities and the environment where we operate, contributing to the development of sustainable energy in Mexicoโ, said Esteban Trouet, Operations Sr. Director for Techint Engineering & Construction- North Region.
The start of construction is targeted for early 2027, subject to the completion of project financing and other customary conditions precedent. The EPC agreement therefore represents a step towards construction, rather than confirmation that the facility has entered the construction phase.
Pacifico Mexinol Targets Operations in 2030
Pacifico Mexinol is planned as a 6,130-metric-ton-per-day ultra-low-carbon methanol complex. Once operational in 2030, the development is expected to become the worldโs largest standalone ultra-low-carbon chemical production facility.
The complex is expected to produce approximately 175,000 metric tons of RFNBO methanol annually, alongside 175,000 metric tons of Recycled Carbon Fuel (RCF) methanol and 1.8 million metric tons of ultra-low-carbon methanol from natural gas with carbon capture.
The Pacifico Mexinol electrolyzer facility will provide renewable hydrogen for the RFNBO production component of the wider complex. Its development is a central part of the projectโs plans to produce lower-carbon chemical products for global markets.
With the EPC agreement signed, Transition Industries, Siemens Energy and Techint E&C will advance the facility towards the targeted early 2027 construction start, while the wider Pacifico Mexinol project remains scheduled to begin operations in 2030.
