The World Hydrogen Summit 2025 took place in Rotterdam, Netherlands, gathering government officials and business representatives from over 130 countries to discuss the advancement of the hydrogen economy. The event emphasized the practical implementation of hydrogen technologies rather than mere discussion. Rotterdam, a crucial energy supply port in Europe, showcased its transition to becoming a global hydrogen hub, with investments in green hydrogen production facilities and infrastructure. The European Union's strong support for renewable energy and hydrogen policies, such as the Comprehensive Energy Strategy and the Renewable Energy Guidelines, sets a framework for the industry to thrive. However, challenges lie ahead for countries like Korea, as they need to align with EU regulations like the Carbon Border Adjustment System and focus on developing a robust national hydrogen strategy to stay competitive. Overall, the sentiment toward hydrogen at the summit was positive, highlighting its role in addressing the climate crisis and driving innovation in high-tech industries.
