Hy24 S.A.S.

Hy24 S.A.S. is a Paris-based investment manager dedicated to clean hydrogen infrastructure. Formed as a joint venture between Ardian and FiveT Hydrogen, the firm structures and manages funds that back large-scale projects across the hydrogen value chain, from production (including electrolysis) to conversion, storage, distribution, and end-use infrastructure.

For the chemical industry, Hy24’s focus is on financing assets that enable low-carbon hydrogen as a feedstock and energy source, supporting decarbonization in segments such as basic chemicals, refining, ammonia and fertilizers, and energy-intensive materials. Its investments typically target mature or near-commercial infrastructure and operate in cooperation with industrial partners, utilities, and technology providers across Europe, North America, and other regions. Hy24 is known for managing the Clean Hydrogen Infrastructure Fund, which concentrates capital into projects that aim to scale reliable hydrogen supply and associated logistics for industrial and heavy-mobility applications.
