Scaling up the hydrogen economy
We are the world's first and largest hydrogen private equity asset manager. We are investing across the hydrogen economy to deploy the infrastructure and technologies needed for a low-carbon, resilient and sovereign economy.
Decarbonizing our economies
With our funds, we are supporting several hydrogen project developers in deploying their infrastructure and technologies in Europe, the Asia-Pacific region, North America and the MENA zone, covering those geographies that have made hydrogen one of the pillars of their decarbonization strategies. To date, we have made 11 investments to support Hy2gen, H2 Mobility, Enagas Renovable, Everfuel, Elyse Energy, InterContinental Energy, Stegra, HysetCo, Hexagon Purus, StormFisher Hydrogen and H2SITE.
To reach sustainable growth by 2050
Industry
Our company was born in 2021 from the combination of Ardian, one of the world's leading private equity firms, and FiveT Hydrogen, a hydrogen focused investment platform. Our team brings together more than 45 professionals and operational partners with a proven industrial expertise in Paris, Zurich, Singapore, and New York.
Asset management
We invest with the utmost care to create a new hydrogen asset class. It's a requirement that compels us. Both by applying the strictest environmental, social and governance standards (European taxonomy, SFDR rules), and by seeking strong economic performance for our investors.
