Should You Invest in Methanol and Ammonia Bunkering in Singapore

Singapore’s position as the world’s largest bunkering hub gives it a decisive advantage in shaping the next phase of maritime energy. In 2024, the country supplied 54.92 million tonnes of marine fuel, an increase of 6 percent from the previous year. Shipping accounts for about 7 percent of Singapore’s GDP, and its trade-to-GDP ratio of 322 percent reflects the economy’s dependence on global shipping routes. At the same time, the sector contributes nearly 3 percent of global greenhouse gas emissions, making decarbonization both an environmental necessity and an economic imperative.

The Maritime and Port Authority has turned this challenge into a growth strategy. By integrating new fuel trials, infrastructure planning, and regulatory frameworks, Singapore aims to become the first global port capable of handling methanol and ammonia on a commercial scale.

 

This alignment of national climate commitments with market opportunity allows investors to enter a state-backed transition rather than a speculative one.

How the transition is taking shape

The shift toward methanol and ammonia fuels is already visible in Singapore’s port operations. In 2024, the Port of Singapore conducted its first live ammonia trial and bunkered 1,626 tonnes of methanol. These efforts build on the International Maritime Organization’s 2023 emission targets, which call for a 40 percent reduction in carbon intensity and at least 5 percent adoption of zero or near-zero fuels by 2030.

Singapore has operationalized these goals through clear standards. Technical Reference 129 on Methanol Bunkering, introduced in 2025, defines procedures for safe transfer and handling, while the new licensing framework requires transparent digital monitoring. Partnerships with Eastern Pacific Shipping, ABS, and Lloyd’s Register are now converting these rules into practice through ammonia dual-fuel vessel programs.

As a result, regulation, infrastructure, and technology are advancing together, creating an investable environment built on safety, traceability, and compliance.

Where capital meets opportunity

Singapore’s emerging green bunkering sector offers investors defined entry points across infrastructure, digital systems, and the growing ammonia supply chain. Methanol demand alone is projected to reach 1 million tonnes per year by 2030, while total investments in alternative bunkering, port upgrades, and vessel retrofits are expected to exceed US$5 billion by the end of the decade.

These indicators confirm that Singapore’s transition has moved from the pilot stage to scalable industrial planning.

Infrastructure readiness

Tuas Port has been declared ready for commercial methanol bunkering after completing its first simultaneous bunkering and cargo operation. This readiness makes it possible to deploy capital immediately into storage and barge assets instead of waiting for regulatory certainty. The port’s scale and automation make it well-suited for alternative fuels, while its integration into Singapore’s wider logistics ecosystem ensures throughput efficiency as adoption grows. By comparison, Rotterdam’s annual methanol volumes remain below 1,000 tonnes, which places Singapore ahead in operational capacity and standardization.

Digital integration and efficiency

The same digital backbone that supports conventional fuels now extends to green fuels. Since April 2025, all suppliers have issued electronic bunker delivery notes, allowing real-time data transfer to the Maritime and Port Authority. Trials have shown that the system can shorten bunkering time by up to three hours and reduce documentation errors by more than 80 percent. These operational savings directly enhance asset utilization and cash-flow cycles for fuel suppliers.

For investors, this creates opportunities in digital verification, emissions-tracking, and compliance platforms that will become essential as global shippers integrate environmental performance into chartering and finance decisions.

Ammonia conversion advantage

Ammonia integration is advancing through brownfield adaptation. The Fortescue Green Pioneer’s ammonia-diesel trial in 2024 used existing facilities at Vopak Banyan Terminal, proving that chemical storage assets can be modified for bunkering at lower cost. This approach can reduce new capital expenditure by 30 to 40 percent, allowing terminal operators and infrastructure funds to scale faster while maintaining safety standards. When compared with greenfield development, this model lowers execution risk and provides faster access to commercial throughput once safety certification is standardized.

Government-backed pipeline

Government-led projects continue to anchor investor confidence. On Jurong Island, the Energy Market Authority and Maritime and Port Authority are developing a complete ammonia ecosystem. Two shortlisted consortia, Keppel Infrastructure Division and Sembcorp-SLNG, are competing to build a 55 to 65 megawatt ammonia-fueled power plant with a 100,000 tonne per year bunkering facility.

The project award, expected in 2025, will bring Singapore’s first full-scale ammonia supply chain online by 2027 or 2028.

Green ammonia could cut lifecycle emissions by up to 90 percent when produced using renewable hydrogen, establishing Singapore as a reference model for other major bunkering ports in Asia.

Evaluating risk and timing

Despite this progress, the market remains young. Methanol and ammonia infrastructure is still limited, and supply chains for green variants are underdeveloped. Retrofitting ships for methanol takes up to one year, and dedicated ammonia bunker vessels must be newly built. High upfront costs and constrained shipyard capacity continue to slow adoption. Methanol-fueled services have achieved fuel-efficiency gains of up to 35 percent, yet operating costs remain elevated due to limited bio and e-methanol supply.

Safety and technology maturity present further challenges. Ammonia’s toxicity requires advanced leak detection and crew training, while methanol’s high flammability adds operational complexity. Engine technology, though improving, is not yet standardized, and maintenance costs remain high. These realities mean investors should view green bunkering as a staged opportunity rather than a short-term trade.

The most practical timeline for scalable returns begins once the Jurong Island project becomes operational. Methanol represents the transitional phase through 2030, while ammonia will define the market’s structural future beyond that point.

Institutional investors can begin positioning in port assets and logistics networks, while technology and venture capital can focus on digital compliance and emissions auditing systems that will underpin global green shipping corridors.

The investment outlook

Singapore’s green bunkering market now offers predictable entry conditions rarely seen in early-stage energy transitions. Policy, infrastructure, and technology are converging, but yield growth will follow capacity expansion rather than immediate price premiums. Institutional and infrastructure funds can move first through equity in port logistics, storage, and digital systems that generate stable cash flows within three- to five-year horizons. Industrial players and energy majors should prepare for deeper exposure after 2027 when ammonia supply and vessel adoption reach commercial scale.

Short-term volatility will depend on carbon pricing and green-fuel cost parity, but regulatory alignment limits downside risk. Singapore’s methanol and ammonia strategy is not a speculative play, but a policy-anchored asset class suited for investors seeking long-duration, ESG-compliant exposure to Asia’s maritime economy.
