The Monaco Hydrogen Forum advanced the use of this promising and clean energy source.

Can hydrogen be considered the new public energy frontier towards transport decarbonisation? Its use is promising but rigorous management of the risks associated with its flammability must be ensured. The 4th edition of the Monaco Hydrogen Forum held in the Principality on the 1st and the 2nd December 2025, promoted by the Monaco Hydrogen Alliance under the High Patronage of H.S.H. Prince Albert II of Monaco, gave the stage to a series of meaningful insights and debates involving international leaders, policy makers and experts towards the near future evolution of clean hydrogen. 

The meeting addressed the main applications of hydrogen in key sectors of Economy and Transport, as well as retrofit technology, financing mechanisms, cross-border coordination to encourage a new geopolitical and industrial advance to a low-carbon hydrogen economy. Hydrogen, in fact, offers great advantages, being net zero (zero CO2 emissions), versatile and able to store excess energy from solar and wind energy, making renewables fully reliable in terms of continuous electricity supply. Moreover, it can be used in fuel cells and engines, for heat and electricity, and as an industrial raw material.

For these reasons, hydrogen represents a driver with great potential. from smart energy systems to offshore production at scale, increasingly supported by global policy tools and regulations, like subsidies, tax incentives, carbon pricing, border adjustment mechanisms, public procurement criteria and clean-fuel standards.

As reaffirmed by the panelists, only a coherent regulatory framework can allow a wide diffusion of this non-pollutant-impact energy source, by 2030 and beyond.

The speakers also highlighted how production at sea is the most suitable stage to ensure a safe use of hydrogen. The Monaco Hydrogen Alliance is involved on the front lines of this subject. Since 2024, it has been promoting the International Taskforce on Hydrogen Mobility in Coastal Areas (ITHCA) with the aim to explore collaborative opportunities, discuss challenges, and accelerate the transition to zero-emission maritime transport counting on a network of leading startups and companies focused on cutting-edge hydrogen technologies. The recent drafting of a White Paper, named: "Waves of Change: The Future of Hydrogen Mobility in Coastal Areas" offers an inspiring roadmap addressed to encourage cross-disciplinary collaborations.

The offshore hydrogen production would empower the energy use of offshore wind, wave, and tidal floating infrastructures, directly fuelled at source through the so-called marine electrolyser integration system. New digital technologies and the Artificial Intelligence, are proving to be valid allies in the development of such projects, by monitoring offshore assets, optimising production, managing variability, and connecting offshore hydrogen with onshore demand centres. Once fully operational, large-scale decarbonisation effects would soon be evident.

The development of the existing Hydrogen valleys and the building up of new ones is essential to accelerate this shift. These are regional ecosystems for integrated H2 production, storage, transport, and use, evolving into larger hydrogen corridors that link these valleys across Countries, forming a strategic domino of transnational networks made of equipped hydrogen ecosystems interconnecting airports and ports.

A key element in controlling costs and impose hydrogen as a leading substitute of energy fossil sources, notably gas and oil.

The application of hydrogen technology to the Motorsport sector is equally under discussion. A targeted session of the Forum emphasised the growing interest in hydrogen technology for the launch of new sports competitions such as the FIA Extreme H, the first world's competitive racing challenge with hydrogen vehicles, and the Nascar Cup Series challenge in United States. The world's major car manufacturers are therefore already heavily investing in clean technology, and great results are expected in a short time.

The 4th Monaco Hydrogen Forum has therefore encouraged a novel mobility addressed to reverse the negative trend in terms of pollutant impact on the natural environment and the health status of living beings, towards a fully regenerative socio-economic dimension.***
