Transition Industries Signs Definitive EPC Agreement with Siemens Energy and Techint E&C for 210 MW Hydrogen Facility in Mexico
Transition Industries LLC has announced the signing of a definitive Engineering, Procurement and Construction (EPC) agreement with Siemens Energy and Techint Engineering & Construction (Techint E&C) for an approximately 210-megawatt (MW) electrolyzer facility at its Pacifico Mexinol project in Sinaloa, Mexico. The agreement marks a significant step forward in the development of renewable hydrogen infrastructure designed to support the production of lower-carbon fuels and chemical products.
The EPC agreement is subject to customary conditions precedent, including the completion of project financing. Once these conditions are satisfied, the agreement will provide a framework for advancing the electrolyzer facility from engineering and planning into the construction phase. The latest milestone builds on the Front-End Engineering Design (FEED) contract announced in August 2025, demonstrating continued progress toward developing the hydrogen production infrastructure required for the broader Pacifico Mexinol complex.
The electrolyzer facility will incorporate Siemens Energy’s Elyzer P-300 electrolyzer technology, which will be used to produce renewable hydrogen. This hydrogen will support the production of renewable fuels of non-biological origin (RFNBO) within Pacifico Mexinol’s planned ultra-low-carbon methanol complex, which is designed for a total production capacity of 6,130 metric tons per day.
The project represents an important development in the integration of renewable hydrogen into large-scale chemical manufacturing. By combining electrolyzer technology with the planned methanol production infrastructure, Pacifico Mexinol aims to establish a production model that can contribute to the growing demand for lower-carbon fuels and industrial chemicals.

The signing of the definitive EPC agreement establishes the next stage of cooperation among Transition Industries, Siemens Energy and Techint E&C. The agreement is intended to translate the facility’s engineering design into an integrated delivery framework, aligning the technology and construction capabilities required to develop the approximately 210 MW electrolyzer installation.
Transition Industries is developing Pacifico Mexinol as a major ultra-low-carbon methanol production project in Mexico. The electrolyzer facility is a key part of the planned development because renewable hydrogen will be used to support the production of RFNBO methanol. The project’s scale and technical requirements make coordination among the project developer, electrolyzer technology provider and engineering and construction contractor essential to its successful execution.
Construction of the electrolyzer facility is expected to begin in early 2027, subject to the satisfaction of the agreement’s conditions precedent. The project’s schedule will therefore depend on completing the necessary financing and other customary requirements before construction activities can proceed.
The transition from FEED to a definitive EPC agreement represents a meaningful advancement in project preparation. While the FEED phase establishes the engineering basis for the facility, the EPC agreement creates a structured approach for moving toward delivery. It also reinforces the partners’ shared role in bringing together equipment, engineering and construction capabilities for a project intended to support industrial decarbonization.
Transition Industries Highlights Renewable Hydrogen Milestone
Rommel Gallo, CEO of Transition Industries, the parent company of Pacifico Mexinol, described the agreement as a significant milestone for the project.
“Moving from front-end engineering to a signed EPC agreement is a significant milestone for Pacifico Mexinol,” Gallo said. “This agreement brings together Siemens Energy’s electrolysis technology and Techint’s 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.”
Gallo’s comments highlight the strategic importance of renewable hydrogen to the Pacifico Mexinol development. The technology is intended to support the production of renewable methanol while contributing to a wider industrial transition toward lower-carbon feedstocks and fuels.
Renewable hydrogen can play an important role in sectors where reducing emissions is technically challenging, including chemical production and other energy-intensive industrial activities. Integrating hydrogen production into a large-scale methanol complex provides a pathway for incorporating renewable inputs into industrial fuel and chemical supply chains.
For Transition Industries, the agreement represents progress toward its objective of developing large-scale infrastructure capable of serving international markets seeking lower-carbon alternatives. The company’s approach combines hydrogen production with methanol manufacturing, creating an integrated project designed to address multiple aspects of the industrial value chain.
Siemens Energy to Supply Elyzer P-300 Technology
Siemens Energy will contribute its Elyzer P-300 electrolyzer technology to the facility. The approximately 210 MW installation would be the company’s largest electrolyzer installation in the Americas, according to Dan Restrepo, Head of Electrolyzer Sales Americas.
“At approximately 210 MW, this hydrogen plant would be Siemens Energy’s 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,” Restrepo said.
The planned capacity underscores the scale of the hydrogen infrastructure being developed for Pacifico Mexinol. Electrolyzers use electricity to split water into hydrogen and oxygen. When powered by qualifying renewable electricity, the process can produce renewable hydrogen that can serve as a feedstock for industrial applications, including the production of certain lower-carbon fuels and chemicals.
At Pacifico Mexinol, the renewable hydrogen produced by the Elyzer P-300 technology will support RFNBO methanol production. This component is intended to complement the project’s broader methanol manufacturing system and help diversify the feedstocks used across its planned product portfolio.
The project also highlights the role of large-scale electrolyzer installations in expanding renewable hydrogen production beyond smaller demonstration facilities. By incorporating an approximately 210 MW hydrogen plant into a major chemical complex, the partners are targeting an industrial-scale application with the potential to support the development of lower-carbon fuel production in the Americas.
Techint E&C to Support Engineering and Construction
Techint E&C will work alongside Siemens Energy and Transition Industries to advance the facility under the EPC agreement. The company brings engineering and construction capabilities to the project, supporting the integration of the electrolyzer technology into the planned industrial infrastructure.
Esteban Trouet, Operations Senior Director for Techint Engineering & Construction–North Region, emphasized the company’s commitment to the development and execution of Pacifico Mexinol.
“We 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 Mexico,” Trouet said.
The statement highlights the importance of safe and responsible project execution alongside technical delivery. Large industrial developments require coordinated engineering, procurement, construction planning and technology integration, as well as attention to workforce safety, environmental considerations and relationships with surrounding communities.
Through its collaboration with Siemens Energy, Techint E&C will contribute to the next stage of the facility’s development. The partnership is intended to bring the project’s design and technology requirements together within a unified delivery framework as Pacifico Mexinol progresses toward its planned construction phase.
Pacifico Mexinol Targets Operations in 2030
Once operational in 2030, Pacifico Mexinol is expected to become the world’s largest standalone ultra-low-carbon chemical production facility, according to Transition Industries. The planned complex will produce three principal categories of methanol, with annual output expected to include approximately 175,000 metric tons of RFNBO methanol, 175,000 metric tons of Recycled Carbon Fuel (RCF) methanol and 1.8 million metric tons of ultra-low-carbon methanol produced from natural gas with carbon capture.
The production plan combines different pathways for supplying methanol to global markets. RFNBO methanol will be supported by renewable hydrogen produced at the electrolyzer facility. RCF methanol will represent a separate product category, while the natural-gas-based methanol production route will incorporate carbon capture as part of the project’s lower-carbon production model.
Together, these planned production streams are intended to help address demand for methanol and related chemical products while supporting efforts to reduce the carbon intensity of industrial supply chains. Methanol is used in a wide range of industrial applications and serves as a feedstock for chemicals, materials and fuels. Demand for lower-carbon alternatives has increased interest in production approaches that incorporate renewable inputs, recycled carbon and carbon capture technologies.
The approximately 210 MW electrolyzer facility is therefore an important part of Pacifico Mexinol’s overall development strategy. Its role in producing renewable hydrogen will support the project’s RFNBO methanol output and contribute to the integration of renewable energy technologies into large-scale chemical manufacturing.
