Résumé
Clean hydrogen, as an energy vector and a sustainable chemical feedstock, is a pillar of the energy transition and key contributor to meeting the targets for net zero greenhouse gas emissions by 2050 and thereby to building a climate-resilient society.
Reaching these objectives requires us to ensure viable materials solutions for implementation of hydrogen technologies in the short term, while also addressing the long-term requirement of safeguarding the sustainability of the hydrogen sector through a radical reconsideration of the criticality of the chemistries, materials and components.
