Three environmentally friendly solutions developed by Air Liquide to help improve air quality and fight climate change have been recognised by the Solar Impulse Foundation.

Created by Swiss psychiartrist and balloonist Bertrand Piccard, the Solar Impulse Foundation is selecting 1,000 solutions that protect the environment in a profitable way and awarding them with the Solar Impulse Efficient Solutions Label.

This label serves as a new and credible symbol that can be applied to products, processes and services and serves as a guarantee of quality to those looking to implement clean solutions, and affords a competitive edge to the innovators behind them.

Air Liquide, who has been supporting the Solar Impulse adventure since 2013, submitted several solutions developed or supported by the French company for certification. Three of these solutions have now received the Solar Impulse Efficient Solution label:

  • The Nexelia™ solution for metal fusion includes connected oxygen lances that make it possible to automatically control and adjust oxygen injection in the blast furnace during the production of cast iron. This new digital technology enables energy savings by automatically adapting the flow of oxygen in real time to keep the temperature steady throughout the furnace.
  • The Eco Chiller is a device that makes it possible to reuse the cold generated during phase changes from liquid to gas. The immediate use of the energy recovered allows substantial cost savings as well as reducing CO2 emissions.
  • Air Liquide’s cryogenics-based energy recovery solution makes it possible to recover energy lost when gas is converted from high-pressure in pipelines to lower pressure for their ultimate industrial use. This recovered energy is then converted into liquid hydrogen and/or liquefied natural gas.

Air Liquide also submitted a solution developed by Grenoble-based start-up Waga Energy which is supported by Air Liquide Venture Capital (ALIAD).

The Wagabox®, an innovative purification unit which purifies and valorises the biogas produced spontaneously by the decomposition of stored or buried waste in order to produce biomethane, which is injected into the natural gas grid, was also awarded the Solar Impulse Efficient Solution label.
