Grow with reduced carbon intensity
Energy efficiency is a key focus of the Group’s World Business Lines and activities, which constantly strive to minimize the energy and environmental footprint of its products and services.
This optimization is a combined result of:
- Technological solutions proposed by Air Liquide in its production process
- Scale effects, co-production and synergies, in particular through the development of its pipeline network
- The operational optimization of its production units
- The solutions chosen in terms of energy and commodities supplies
Energy efficiency in production units
The energy efficiency of oxygen units improved in 2015, in particular thanks to the commissioning of new production units.
Evolution of energy consumption, per m³ of gas produced, of air separation units (ASU)
The energy efficiency of our hydrogen units temporarily decreased in 2015, in particular due to the gradual commissioning of the large hydrogen unit in Yanbu, Saudi Arabia which has not yet reached optimal efficiency.

Transportation and efficiency of truck deliveries
87% of all gas deliveries are made via pipeline or through units on customer sites. As a result, only 13% of air gases or hydrogen are transported by truck.
Between 2011 and 2015, thanks to the success of programs to optimize deliveries, the efficiency of industrial gases transportation continued to improve.
