Engie, an energy company, advocates for urgent action to secure Europe's decarbonisation path, highlighting the necessity of supporting technologies like hydrogen. The company believes that the European 2030 target, 'Fit for 55', is achievable through the utilization of mature technologies such as solar, wind, and electric vehicles, emphasizing the need for their rapid deployment. To reach carbon neutrality by 2050, Engie proposes a 4% annual reduction in emissions and stresses the importance of massive electrification and the development of green molecules, particularly renewable hydrogen. They foresee a significant rise in hydrogen demand by 2050, driven by applications in aviation, shipping, and heavy industry. Engie suggests a substantial increase in renewable energy production and flexibility solutions to meet European targets, focusing on a more flexible energy system that integrates battery storage, renewable hydrogen production, and demand-side solutions. This transformation requires immediate preparation and infrastructure development. Engie's vision underscores the pivotal role of hydrogen in achieving sustainable energy transition and carbon neutrality.
