Q0046
Malaysia's earliest large green-hydrogen users are most likely to be industries that already consume conventional hydrogen: methanol, ammonia and fertiliser production, and oil refining. Maritime fuels and selected heavy transport could follow where supply is concentrated around ports or fleets. Steel, aviation fuels, power generation and general mobility are longer-term or more conditional opportunities because they need new equipment, stronger policy support or a larger cost reduction.
Hydrogen projects need customers that can absorb meaningful volumes and pay the cost of lower emissions. Targeting existing industrial users can reduce technology and infrastructure risk, while pursuing weak use cases too early could lock scarce renewable electricity into expensive and inefficient applications.
Southeast Asian hydrogen demand is already concentrated in ammonia, refining and methanol. The IEA's 2025 regional assessment estimates that Malaysia represented 22% of Southeast Asian hydrogen demand in 2024 and 69% of the region's methanol demand. Existing plants can create anchor demand, although conversion may still require new equipment and a price premium.
Ammonia production requires hydrogen as a feedstock, so low-emissions hydrogen can substitute for fossil-based supply without inventing a new molecule market. Malaysia has enough existing ammonia demand to support economies of scale, according to the IEA, but competitiveness depends on gas prices, plant configuration, carbon rules and reliable renewable supply.
Refineries already use hydrogen for hydrotreating and other processes. They can become early buyers because the application is established, but long asset lives, uncertain fuel demand and limited willingness to pay for a premium can constrain contracts.
Malaysia has a substantial methanol industry and announced projects that contemplate hydrogen-derived methanol. Demand could come from existing chemical markets and emerging marine-fuel use. The business case must distinguish genuinely low-emissions methanol from products that rely on carbon inputs with weak lifecycle credentials.
Hydrogen, ammonia or methanol can be considered for shipping, port equipment, buses and heavy fleets where vehicles return to a base and refuelling infrastructure can be shared. Passenger cars and dispersed light vehicles face strong competition from battery-electric technology.
Hydrogen-based iron and steel, high-temperature heat, sustainable aviation fuel and dispatchable power could become important. In Malaysia, however, these uses need new facilities, lower delivered costs, dependable fuel supply and clear policy demand before they can anchor major projects.
