The United Nations Development Programme (UNDP) has been working closely with China since 2003 to leverage hydrogen as a driver for Sustainable Development Goals (SDGs) achievement. This collaboration has led to significant milestones, including China now possessing the world's largest fleet of fuel cell vehicles and hydrogen refueling infrastructure. In partnership with key stakeholders like the China Hydrogen Alliance, initiatives have been launched for large-scale renewable hydrogen production demos, blockchain traceability systems, and capacity-building programs. These efforts not only support China's dual-carbon objectives but also aim to share insights globally. Challenges persist, such as the lack of harmonized international regulations and certification systems for hydrogen trade and safety. Addressing such issues is crucial to ensure social and environmental safeguards are in place for the industry's sustainable growth. Workforce readiness is highlighted as a priority, emphasizing the need to upskill technicians, engineers, and promote gender-responsive access to emerging green jobs. UNDP is committed to promoting the development of the green hydrogen energy industry, aligning with international standards, and contributing to China's long-term energy targets. Initiatives like the 2025 Hydrogen Specialized and Innovative Entrepreneurship Competition are set to empower small and medium enterprises in green technology innovation and foster industry-academia-research collaboration. The focus remains on building a hydrogen ecosystem in China and globally, driving a just, inclusive, and sustainable energy transition. The article showcases a positive sentiment towards hydrogen, highlighting its potential as a clean energy solution and the collaborative efforts underway to realize a greener future.
