According to Reuters, Mexico's government has ordered the expropriation of a H₂ plant at a Pemex oil refinery that was sold to French company Air Liquide during the previous administration, after officials ordered a temporary occupation of the facility last December.

Oil refineries use H₂ to reduce the sulfur content in petroleum products, especially diesel. The government's announcement also cited the need to ensure Mexico's "energy sovereignty" via the expropriation of the privately-operated facility.

Under his predecessor, centrist former President Enrique Pena Nieto, Pemex's refining arm signed a 20-year contract with Air Liquide in 2017 to supply H₂ for Tula's operations in a bid to lower costs and boost efficiency.

The Tula facility, located in central Hidalgo state north of the Mexican capital, is Pemex's second-largest refinery currently in operation.
