Siemens Energy, the German energy technology company, and Techint Engineering & Construction (E&C), part of the Italian-Argentine Techint Group, have been selected to carry out the front-end engineering design (FEED) for a 210 MW electrolysis plant at the Pacifico Mexinol low-carbon methanol project in Sinaloa, Mexico.

The plant is expected to produce over 4,000 kg of green hydrogen per hour. Once operational in 2029, it is set to be the largest of its kind in the Americas and among the largest globally.

The $3.3 billion Pacifico Mexinol project, led by U.S.-based Transition Industries in partnership with the International Finance Corporation (IFC), will also include third-party consortium execution. The complex will produce an estimated 350,000 metric tons of green methanol and 1.8 million metric tons of blue methanol annually, with the latter using natural gas combined with carbon capture. Production will support fuels and industrial materials, with exports planned via the Port of Topolobampo.

The project is subject to a final investment decision (FID).
