Siemens Energy and Techint win EPC contract for a 210 MW electrolyzer at Mexico's Pacifico Mexinol

Transition Industries announced the agreement on Oct. 28. It follows a front-end engineering design contract announced in August 2025, and it is still subject to conditions precedent, including completion of project financing, the company said. If they are met, crews would break ground in early 2027.

The plant will use Siemens Energy's Elyzer P-300 electrolyzers to make renewable hydrogen for methanol that qualifies as a renewable fuel of non-biological origin, or RFNBO. Dan Restrepo, Siemens Energy's head of electrolyzer sales for the Americas, said that at about 210 MW it would be the company's largest electrolyzer installation in the Americas. Techint, which works with Siemens Energy under an alliance, takes on the construction side.

The electrolyzer is one part of a planned complex built to make 6,130 metric tons a day of ultra-low-carbon methanol. According to Transition Industries, Pacifico Mexinol is due to start operating in 2030 and to produce about 175,000 metric tons a year of RFNBO methanol, the same amount of methanol made from recycled carbon fuel, and 1.8 million metric tons of methanol made from natural gas with carbon capture.

The companies did not disclose the value of the contract or a date for closing the financing.
