The European transition to climate neutrality is a multifaceted process driven by key initiatives like the European Climate Law and the European Green Deal. Energy system modeling is recognized as pivotal in fostering multi-level governance to navigate the complexities of energy transitions efficiently. Research studies underscore the significance of hydrogen investments, particularly in areas like North Sea offshore wind, grid infrastructure, and power prices, emphasizing their role in enhancing energy security and meeting climate policy objectives. Europe's energy landscape is evolving towards sustainability and resilience, supported by investments in renewable energy sources like wind and solar power. The synergy of sector coupling and transmission reinforcement is explored to achieve a highly renewable energy system. With diverse options for decarbonization and a focus on a cost-optimized approach, Europe aims to reach its climate targets and advance towards a prosperous, sustainable future.
