Abstract

Hydrogen is poised to play a vital role in Europe's transition to a low-carbon economy while enhancing energy security by reducing reliance on imported fossil fuels. However, future hydrogen demand remains highly uncertain, shaped by sectoral priorities, technology choices, cost dynamics, and policy direction. This study undertakes a comparative assessment of hydrogen demand projections across 20 studies—including academic, governmental, and private sector sources—focused on decarbonizing Europe's energy system by 2050. Both electrolytic and non-electrolytic hydrogen pathways are quantified, with demand estimates varying widely from a median of 50 Mt to a maximum of 108 Mt by 2050. Findings consistently highlight hydrogen's essential role in hard-to-abate sectors in transport and industrial applications, with a growing emphasis on hydrogen-derived fuels like ammonia and methanol. These insights are crucial for informing infrastructure planning and guiding strategic investments to support Europe's long-term climate and energy objectives.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
