This publication presents findings from the APEC-funded project PPSTI 101 2024: Advancing Energy Transition and Circular Economy in Building Up Capabilities to Net Zero/Carbon Neutrality, which examined regional readiness and strategic pathways for green hydrogen deployment across APEC economies, recognising diverse transition pathways and regional conditions. The study adopted a multi-phase approach comprising desktop research, a cross-economy survey involving 141 respondents from government, industry and academia, five expert interviews, a two-day technical seminar in Kuala Lumpur involving participants from 11 APEC economies, and a Focus Group Discussion (FGD) with 80 participants. Key challenges identified included high production costs, fragmented standards, financing barriers, infrastructure limitations and workforce gaps. Opportunities were highlighted in electrolyser innovation, renewable energy integration, hydrogen hubs and regional collaboration. The publication proposes ten strategic recommendations to strengthen policy alignment, innovation, financing, ecosystem governance, capacity building and regional cooperation to support sustainable and inclusive green hydrogen development across APEC economies.
