In a new milestone for the energy transition, Techint E&C and Siemens Energy will develop the Front-End Engineering Design (FEED) for a green hydrogen production plant in Sinaloa, Mexico. The facility is part of the Pacífico Mexinol project and is set to become the largest low-carbon methanol plant in the Americas—and one of the most significant worldwide. Operations are expected to begin around 2029. The project is being managed by Transition Industries, develops, constructs, and operates world-scale facilities for methanol and hydrogen with net-zero carbon emissions.

The electrolysis plant will have a design capacity of 210 MW and will produce about 4,000 kilograms of hydrogen per hour. Annual output is projected at roughly 350,000 metric tons of green methanol and 1.8 million metric tons via the blue methanol route. Overall, the complex will be capable of producing around 6,130 metric tons of methanol per day.

“The agreement to participate in the development of Mexinol marks an important first step on a challenging path,” said Alejandro Maluf, President – North America Region, during the signing ceremony. “But I have no doubt that, through our collective effort, we will move steadily toward making this ambitious project a reality.”

The Pacífico Mexinol project will play a major role in decarbonizing the global chemical industry. According to Esteban Trouet, Project Director of Techint E&C in Mexico, methanol will be key to meeting the environmental regulations set to take effect from 2030 onward. He noted that methanol is a key input for producing plastics and derivatives in the petrochemical industry and is also emerging as an alternative fuel in the maritime sector.

“The International Maritime Organization, which regulates global shipping, is requiring large vessels to use increasingly sustainable fuels—and that’s where green methanol comes in, replacing conventional diesel or fuel oil,” Trouet explained. “If operators fail to meet these requirements, they’ll face emissions surcharges that will exceed the cost of switching to green methanol.”

Trouet also pointed out that the world still lacks sufficient nuclear, wind, solar, or hydroelectric capacity to eliminate fossil fuels altogether. “It’s estimated that by 2050, we’ll have the technology in place to fully meet global demand,” he said. “Until then, low-carbon methanol will serve as a key transition fuel, helping us meet new regulations and continue advancing the decarbonization effort in the decades ahead.”

The electrolysis plant will use Siemens Energy’s Elyzer P-300 technology, a high-power system designed to integrate with renewable energy sources to produce green hydrogen.

Techint E&C will be in charge of the balance of plant (BOP). “Our track record in developing complex engineering projects and our strong construction capabilities across Latin America are well known,” said Trouet. “We bring specific expertise to this part of the project and to its integration with the wider Pacífico Mexinol complex. We’re working closely with Siemens, advancing step by step with detailed coordination and leveraging each team’s strengths.”

In addition, Techint E&C’s long-standing presence in Mexico adds value in managing the logistics of bringing Siemens technology into the country. The company will advise on the transportation and handling of critical equipment for delivery to the construction site, located near the Sinaloa coast.

With the Pacífico Mexinol project, Techint E&C is taking firm steps in the production of green hydrogen and the large-scale generation of low-carbon methanol. “It will soon allow us to bring greater experience and know-how to new customers. We’re taking a leap that opens new paths and opportunities to contribute to the energy transition," enthused Trouet.

Trouet added that projects like this will multiply in the coming years as global demand for methanol and cleaner energy sources continues to grow. “Heavy industries such as steelmaking, refining, and large-scale manufacturing must meet increasingly strict emissions standards—and some companies haven’t yet reached those targets,” he explained. “Carbon capture and hydrogen production are powerful tools to meet these requirements, so we’ll keep supporting and developing projects of this kind.”

He also underlined the value that the Techint Group brings through its integrated work approach, emphasizing the synergy achieved between the companies. “Our organization can draw on the specialized expertise and global reach of each company and make these available to our customers as required. Right now, we’re contributing to a one-of-a-kind plant, and that experience will stay with us,” Trouet noted.

“Mexinol is a challenge we’re taking on with responsibility, professionalism, and enthusiasm,” concluded Alejandro Maluf. “It’s another opportunity to showcase what we do best: deliver high-impact projects that drive progress in the countries where we operate.”
