Today, when we talk about combatting climate change, we can no longer ignore green hydrogen, which looks to be very promising in decarbonizing certain industrial sectors as well as air and maritime transport in the coming years.
'Decarbonization is now a necessity rather than a choice, for both the public and private sectors alike,' said
This theme was the focus of an event organized by
Green hydrogen will play a potentially fundamental role in decarbonizing the energy system: 'In terms of our outlook at IRENA, hydrogen will fulfil almost 12% of global energy requirements and contribute 10% of the drop in CO2 emissions between now and 2050,' said
The reason is, of course, that 'green hydrogen is the perfect complement to electrification in decarbonizing those sectors in which electrification using renewables is not feasible or financially sustainable,' as
EGP's Head of Innovation
Photovoltaic panels and batteries are proving that this type of rapid drop in costs is possible. With that in mind, Rossi says: 'We need to work on three fronts: increasing the scale of manufacturing activities, increasing the size of the modules that make up the electrolyzers, and innovating to introduce new technologies and new materials, as well as to optimize the design of components and their integration. It's also critical to work on developing the new skills that will be needed to build and operate green hydrogen production facilities.'
The other participants, including representatives from several technology providers and startups selected by Enel to collaborate on a roadmap to reduce costs using an open innovation model, also listed the factors that will help to make green hydrogen fully competitive. These include economies of scale in making the electrolyzers themselves and the cost of carbon dioxide emissions, which impacts polluting technologies but not green hydrogen.
Furthermore, green hydrogen production plants can easily change their power input and thus, as La Camera pointed out, 'green hydrogen can provide flexibility to the energy system and facilitate the integration of new renewables': a twofold benefit for the energy transition to a cleaner system.
For all of these reasons, green hydrogen is now very much part of the European political agenda, as Bernabei noted, pointing out that the conference's subtitle was: 'One year after the launch of the
Lastly, Evelyn Araripe, co-founder of Youth Climate Leaders, drew attention back to the importance of the energy transition for new generations, because - thanks to their huge potential for job creation - clean energies will be able to provide an answer to the two main fears of that young people have about the future: the climate crisis and the lack of employment.
