An international research team led by Prof. Bob van der Zwaan from the University of Amsterdam has analyzed the potential of the 'hydrogen economy' in achieving a sustainable society. Their study, published in Nature Communications, models pathways for decarbonizing the European economy by 2050. The findings indicate that electrification will be the most cost-effective energy source, accounting for about 60% of final energy consumption, while direct hydrogen use is projected to contribute only 6-10%.
