Hydrogène Vert : Le Défi de la Décarbonisation - Hamdi Hached

While the very reality of the energy transition is sometimes questioned, even challenged (Fressoz, 2023), the carryover effect it creates on mineral resources, highlighted by numerous forward-looking studies, appears indisputable. More copper, lithium, nickel, graphite or rare earths: these are the non-exhaustive conditions that will enable us to support the development of electromobility and renewable energies, and thus contribute to limiting global warming, in line with the commit ...

The global energy landscape in 2024 reflects a complex interplay of geopolitical tensions, economic pressures, and uneven progress in clean energy transitions. Despite record growth in renewable energy deployment and advancements in low-carbon technologies, the world continues to fall short of meeting its climate goals. Fragmented markets, entrenched fossil fuel dependencies, and supply chain vulnerabilities continue to challenge energy security and hinder global decarbonization eff ...

The Middle East and North Africa (MENA) region is at a critical juncture, facing an intricate polycrisis defined by interlinked challenges including energy insecurity, water scarcity, migration, conflict, and socio-political fragmentation. These crises are not isolated; their interconnectedness amplifies their impact, creating a destabilizing feedback loop that hinders sustainable development and peacebuilding efforts. This paper explores the concept of polycrisis through the lens o ...

In September 2024, scientists at the European Union’s Copernicus Climate Change Service  reported that summer 2024 was the hottest on record globally, and the previous twelve months posted a average global temperature that was a record 1.64 degrees Celsius (2.95 degrees Fahrenheit) above the average during the pre-industrial period, 1850-1900. This was triggered by a combination of a warmer El Niño cycle and the effects of human-caused warming. While it will take more years of such ...

Si la réalité même de la transition énergétique est parfois questionnée, voire remise en cause (Fressoz, 2023), l’effet de report qu’elle crée sur les ressources minérales, mis en évidence par de nombreuses études prospectives, apparaît indiscutable. Plus de cuivre, de lithium, de nickel, de graphite ou de terres rares : telles sont les conditions non exhaustives permettant de soutenir le développement de l’électromobilité et des énergies renouvelables et, ainsi, de contribuer à la ...

The road to decarbonizing the planet runs through the energy transition, which includes the shift from fossil-fueled cars to renewable energy vehicles. This automotive transition is unfolding as a true revolution in the industry. The evolution toward electric and hybrid vehicles has come in tandem with the ascent of Chinese producers. In the current context of geopolitical and technological rivalries, the automotive transition has been marked by an intense trade war, with implicati ...
