Whether we’re riding a bike, driving a car, or traveling by train — mobility is a fundamental part of our lives and is constantly evolving. Behind much of this progress is the important role played by industrial gases.

Gases help make our journeys more comfortable, safer, and more environmentally friendly. For example, they’re essential in welding and cutting metal for vehicle bodies. Several different gases — including helium, argon, and oxygen — are used to inflate airbags. And hydrogen-powered vehicles are paving the way for the future of sustainable mobility.

In local public transportation projects, liquid nitrogen is being used to support subway system expansion. The cryogenic gas freezes the ground to ensure stability and prevent water infiltration.
