Global hydrogen demand is approximately 90 to 100 million tonnes per year, tied to about 800 to 900 million tonnes of carbon dioxide emissions from fossil-based production. Asia, home to large refining and chemical complexes as well as growing steel demand, urgently needs clean hydrogen solutions.
Asia’s priority should be to scale electrolytic hydrogen production anchored in renewable-rich, coastal industrial hubs. Alkaline electrolysis is suitable for low-cost baseload production, proton exchange membrane electrolysis enables fast ramping to capture variable wind and solar energy, and solid oxide electrolysis cells are attractive wherever high-temperature industrial heat can be reused to lower electrical load. Blue hydrogen using autothermal or steam methane reforming with 90 to 95 percent carbon capture offers a pragmatic bridge in gas-advantaged countries if methane leakage is tightly controlled and geological storage is available. Biomass- and waste-to-hydrogen pathways can also supply low-carbon molecules in feedstock-dense regions of Southeast Asia and Japan. Coal gasification with carbon capture and storage should be limited to transitional, site-specific cases in India, while methane pyrolysis merits pilot projects where there are buyers for the solid carbon byproduct.
Across all production pathways, projects are most likely to succeed where power costs fall below roughly 25 to 35 dollars per megawatt hour with capacity factors above 50 to 60 percent, where water treatment or desalination is integrated from the outset, and where certification frameworks exist to verify carbon intensity and unlock bankable offtake agreements.
