The expanded Memorandum of Understanding (MOU) will see the companies collaborate on low-carbon hydrogen production, storage, transport and refuelling infrastructure.

The industrial gas firm and automotive major also plan to deploy fuel cell trucks, buses, and logistics fleets, supported by new hydrogen hubs planned in the three regions.

“Collaborations like this between leading companies across the value chain are essential to building the hydrogen economy,” Armelle Levieux, member of Air Liquide’s Executive Committee, said.

“The progress we have made in South Korea highlights what is concretely possible when industry leaders work together for a more sustainable future.”

The companies say the model proven in South Korea – where more than 37,000 Hyundai fuel cell vehicles and 2,000 hydrogen buses are already operating – will be replicated in Europe and the US.

As co-chairs of the Hydrogen Council, Air Liquide and Hyundai also plan to use their expanded alliance to drive international standards and secure policy support.
