Hy24 will fund the realisation of hydrogen’s global potential as the low carbon energy vector by supporting those infrastructure projects which will deliver the greatest positive returns.

To reach Net Zero by 2050, the world needs power from molecules as well as electrons. Renewables will provide the electrons and produce the Hydrogen. Hydrogen is the clean energy vector that will enable to substitute carbon rich energy uses in hard to abate sectors. It is the ideal energy feedstock for industrial processes, heavy and intensive mobility powering, and the perfect vector to move energy from its production source through space and time.

Hy24 will provide financial capital to fund credible, large-scale green hydrogen infrastructure projects world-wide. We will drive the essential scale-up of the hydrogen economy through our selective support of both supply- and demand-generative projects.

With a keen insistence on respect of the highest Environmental, Social and Governance principles, sustainable investment in accordance with stringent European regulation is a core Hy24 characteristic. On this we will not compromise.

Hy24 will be frontrunner in the funding of sustainable hydrogen infrastructure projects around the world.

Investment Strategy

Projects which make a lasting impact on the environment and society.

Through investments in large-scale infrastructure for the production, storage, and distribution of clean hydrogen, Hy24 will be a key enabler of decarbonization, particularly in the spheres of industry and mobility. We will support hydrogen projects in any country with a strong state support program, with a preference for minority investments in greenfield projects. We will participate in opportunities at any point on the hydrogen value chain, from upstream through mid- and down-stream, based on six focus areas to deliver strong, sustainable infrastructure returns from projects which make a lasting impact on the environment and society.
