In 2018, Air Liquide launched its second Scientific Challenge, focusing on research projects aimed at reducing air pollution and fighting climate change through Essential Small Molecules . In the topic “H₂ is coming!”, the French researcher Christophe Copéret, professor at ETH Zurich, was selected because of the work of his research team on the development of catalysts that convert carbon dioxide (CO₂) into methanol.

On the occasion of the 2019 Paris Air Show, Air Liquide presented its innovative solutions in space and aerospace, such as the use of hydrogen as a viable energy alternative for aircraft. It was also an opportunity to discover new technologies developed for the future Ariane 6 launcher or for electric propulsion for satellites and its projects in connection with space exploration (moon village, ExoMars, etc.).

In 2016, the Group launched a contest called the "Air Liquide Essential Small Molecules Challenge". Competing on the topic "Sunny H₂ in a bottle", American researcher Kevin Sivula was recognized for his work on using photoelectrocatalysis to produce hydrogen.

Inventiveness, curiosity, collective intelligence, and entrepreneurial spirit are at the heart of Air Liquide’s innovation approach. That means developing cooperation with the international scientific community (academics, technology institutes, startups, private R&D…): this is why we have launched the second edition of the Scientific Challenge. Now, the laureates are known.

For many years researchers, industry players and students had to search for the information they needed on the molecules used in their plants and laboratories in various publications. This information, scattered, sparse, and sometimes inaccessible, took a long time to collect and sometimes required complex calculations. But one day, Air?Liquide's Gas Encyclopedia came along and changed everything. In 2017, a new chapter opens.

Molecules have been at the core of Air Liquide’s activities since its creation, as highlighted by the Group signature “Creative Oxygen”. Throughout our history, we have continuously developed a portfolio of technologies including new production processes and applications of these molecules along with the associated know-how, equipment and services. Today, enriching our knowledge on molecules will contribute to explore new horizons and serve Society.
