本論文は、ASEANの電力部門と水素生産を統合した能力拡大モデルを用いて、2050年までのネットゼロ排出達成経路を分析。再エネ・蓄電池の急速拡大（2050年に95％の再エネ比率）と、CCS・水素の拡大（同46％・15％）という2つのシナリオを示し、CCSが水素生産に重要であることを明らかにした。
English
This paper presents a capacity expansion model for ASEAN to achieve net-zero emissions by 2050, integrating electricity and hydrogen production. It identifies two pathways: accelerated renewables and battery storage (95% RE share, 28% battery charge) or CCS and hydrogen (46% CCS, 15% hydrogen). CCS plays a key role in hydrogen production, and grid connectivity reduces storage needs but requires flexibility.

📄 Abstract（原文）
Abstract The Association of Southeast Asian Nations (ASEAN) is at a turning point to drive an energy transition toward a low-carbon future. Investigating ASEAN's decarbonization strategies is timely. We present a capacity expansion model with hourly resolution for ASEAN to meet net-zero emissions by 2050, integrating electricity generation and hydrogen production. The results show two “bookend” pathways. ASEAN can decarbonize its power sector through an accelerated expansion in renewables and battery storage (up to 95% and battery charge up to 28% in 2050) or an expansion in carbon capture and storage (CCS) and hydrogen (up to 46 and 15%, respectively). CCS is found to play a key role in hydrogen production. For power system operation, grid connectivity can lower battery storage demand and power reserves but requires higher power system flexibility. Our findings can help decision-makers identify the roles of key decarbonization strategies in ASEAN and navigate between various scenarios.
