TL;DR: Asia’s green hydrogen boom is being driven by ammonia export deals and record-breaking electrolyzer procurement, led by India, China, Japan, and South Korea. Falling electrolyzer costs and aggressive net-zero targets will push announced capacity past 50 GW by 2027, making Asia the world’s largest green hydrogen trading hub.
Ammonia Deals Anchor the Boom
Green ammonia has become Asia’s preferred hydrogen carrier. In 2024, India’s ACME signed a $5 billion green ammonia supply deal with Japan’s IHI, while South Korea’s Hanwha and Samsung C&T inked offtake agreements exceeding 1 million tonnes annually. Japan’s JERA and Malaysia’s Petronas are co-developing ammonia co-firing projects targeting 20% substitution at coal plants by 2030. According to BNEF, Asia-Pacific green ammonia offtake agreements tripled year-on-year in 2024, reaching 8.4 million tonnes per annum.

Electrolyzer Procurement Hits Record Highs
Electrolyzer orders are surging. India’s NTPC and Reliance placed combined orders exceeding 2 GW in 2024, while China’s Sungrow and LONGi reported a 60% jump in alkaline electrolyzer shipments. Wood Mackenzie estimates Asia-Pacific electrolyzer capacity will grow from 3.2 GW in 2024 to over 22 GW by 2028, driven by subsidies under India’s National Green Hydrogen Mission and China’s provincial hydrogen plans.
Expert Insights: Cost Curves and Policy Tailwinds
“Electrolyzer prices in Asia have fallen 40% since 2022, and we expect another 25% drop by 2027,” says Dr. Chen Lin of the Asia Hydrogen Council. “Ammonia is winning because it reuses existing LNG infrastructure.” Analysts at IHS Markit note that Japan’s $20 billion Green Innovation Fund and South Korea’s hydrogen auction scheme are de-risking early projects.
Future Predictions
By 2030, Asia could account for 45% of global green hydrogen demand, with ammonia imports to Japan and Korea exceeding 3 million tonnes annually. India is poised to become the cheapest producer, targeting $1.5/kg by 2030. Expect consolidation as oil majors like Petronas and Adani acquire smaller developers, and expect electrolyzer gigafactories to cluster in India and China.
FAQ
Q: Why is ammonia preferred over liquid hydrogen in Asia?
A: Ammonia leverages existing LNG terminals and ships, cutting infrastructure costs by up to 60% and avoiding the extreme cryogenic challenges of liquid hydrogen.
Q: Which Asian country leads electrolyzer manufacturing?
A: China dominates with over 60% of global alkaline electrolyzer production, but India is rapidly scaling with lower labor costs and new gigafactories.
Q: What is the biggest risk to this boom?
A: Policy uncertainty and slow certification standards for green ammonia could delay final investment decisions, particularly in Southeast Asia.
