As the global energy transition enters a deep phase, green hydrogen is emerging as the next major opportunity being aggressively pursued by ASEAN nations. At the ASEAN Energy Summit held in Bangkok, Thailand, at the end of July 2026, several green hydrogen cooperation projects were signed, involving a total investment exceeding $12 billion. The latest report from the International Energy Agency (IEA) shows that green hydrogen project reserves in the ASEAN region grew by 300% in the first half of 2026, making it one of the fastest-growing green hydrogen markets globally.
Why is Green Hydrogen Key to the Energy Future?
Green hydrogen is considered a vital component of the global energy future, especially in hard-to-decarbonize sectors such as steel, chemicals, and shipping. Combined with Southeast Asia's abundant solar and wind energy resources, green hydrogen provides a realistic pathway for ASEAN to achieve net-zero emissions targets. Furthermore, green hydrogen possesses energy storage characteristics, which can effectively smooth the volatility of renewable energy and enhance grid stability.
ASEAN Countries Accelerate Deployment with Major Projects Coming Online
- Singapore and Indonesia Cooperate on Sumatra Green Hydrogen Project: Singapore Science Park and the Indonesian state-owned oil company announced on August 1 that they will jointly develop a 100 MW green hydrogen production facility on Sumatra Island. This project utilizes off-grid PV + water electrolysis technology and is expected to commence operation in 2028, producing 15,000 tons of green hydrogen annually. It will supply the Jurong Island industrial cluster in Singapore and include the construction of refueling stations to serve regional hydrogen vessels and heavy trucks in Southeast Asia.
- Malaysia Launches Johor Green Hydrogen Integrated Park: The Malaysian national energy company launched the Johor Green Hydrogen Integrated Park project at the end of July, utilizing combined power from solar and biomass energy. The project will be built in three phases with a total investment of $3.5 billion. The Malaysian Prime Minister stated that green hydrogen is a crucial support for achieving the target of 70% renewable energy share.
- Vietnam Approves National Strategy for Green Hydrogen Development: The Vietnamese government recently approved the National Strategy for Green Hydrogen Development 2026-2035, planning to reach an annual production of 100,000 tons by 2030 and 500,000 tons by 2035. It will prioritize green hydrogen production from offshore wind power in the central and southern coastal regions. The Vietnamese Ministry of Industry and Trade has signed a feasibility study agreement with a major Danish renewable energy company.
Market Size and Investment Prospects
According to the Asian Development Bank's estimates, the ASEAN green hydrogen market is expected to exceed $20 billion by 2030, with a compound annual growth rate of 45%. The ASEAN Centre for Energy (ACE) latest outlook emphasizes that regional green hydrogen cooperation mechanisms and mutual standard recognition will be the focus of the next phase. The ten ASEAN countries have agreed to establish a green hydrogen technology working group, planning to launch a unified green hydrogen certification system in 2027 to promote regional trade and investment.
Challenges Remain, But Opportunities Are More Prominent
Despite the vast prospects, the development of green hydrogen in ASEAN still faces challenges such as weak infrastructure, shortage of technical talent, high green hydrogen costs, and the lack of finalized plans for cross-border hydrogen pipelines. Industry experts point out that ASEAN should pursue a differentiated competitive strategy: Brunei and Indonesia can utilize existing natural gas pipelines for hydrogen blending pilots; Singapore can leverage its role as a financial and trading hub; while Vietnam, the Philippines, and Thailand are positioned to become green hydrogen export bases due to low-cost renewable energy.
Policy Incentives and Capital Deployment
ASEAN countries have recently introduced supportive policies: Singapore announced a capital expenditure subsidy of up to 50% for green hydrogen projects; Indonesia grants a 10-year tax exemption to green hydrogen producers; and Thailand plans to exempt tariffs on imported electrolyzer equipment. These policies will attract global capital to the upstream (renewable energy generation), midstream (electrolyzer manufacturing), and downstream (refueling stations and fuel cell applications) green hydrogen industry chains.
Overall, on the stage of the global energy future, green hydrogen in ASEAN is moving from concept to reality. With projects coming online, policies being refined, and costs decreasing, Southeast Asia is poised to emerge as a major global hub for green hydrogen production and export before 2030. Companies that move ahead in deployment stand to share in the growth dividends of this trillion-dollar emerging market.
