Hy24 is convinced of the potential of hydrogen as a low-carbon energy carrier, and is financing large-scale projects that have a sustainable impact on the economy and society and offer the greatest returns.

To reach Net Zero by 2050, the world needs power from molecules as well as electrons. Renewables will provide the electrons and produce hydrogen. Hydrogen is the clean energy vector that will substitute for 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.

Through its funds, and notably the first one ‘the Clean H2 Infra Fund’, Hy24 is providing financial capital to fund credible, large-scale clean hydrogen infrastructure projects world-wide. Hy24 drives 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. The ‘Clean H2 Infra Fund’ is an Article 9 Fund according to the European SFDR regulation, which classifies funds that meet specific and binding environmental and social criteria.

Hy24 is the frontrunner in the funding of sustainable hydrogen projects around the world.

Investment Strategy

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

Through its infrastructure fund, Hy24 is investing in large-scale infrastructure projects for the production, storage, and distribution of clean hydrogen. Hy24 is a key enabler of decarbonization, particularly in the spheres of industry and mobility. We are supporting hydrogen projects in any country with a strong state support program, with a preference for minority investments with other partners in greenfield projects. We are participating in opportunities at any point on the hydrogen value chain, from upstream through mid- and down-stream. Our objective remains intact: to invest in sustainable projects that have a positive impact on the environment and society without compromising the economic performance expected by our investors.
