The Shipping Industry Has a Growing Appetite for Methanol Fuel

Massive cargo ships that run on green methanol are now sailing scheduled routes, and ports and suppliers are organizing the infrastructure to fuel them.

In July, the world’s largest methanol dual-fuel container cargo ship, the 400-meter-long OOCL Wisdom, completed its first green methanol fueling (or “bunkering”) at China’s Qingdao Port. Days later, Dutch terminal operator VTTI completed its first large-scale green methanol bunkering load at its facility in Dalian, China. On 11 July, 20 organizations spanning shipping, ports, energy, and equipment manufacturing launched a Methanol Fuel Shipping Supply Chain Innovation Alliance to coordinate a national bunkering buildout.

Methanol fuel for shipping barely exists as an industry today. Yet if the global shipping fleet fully converts to methanol fuel, the industry’s annual methanol demand could reach 100 million tons a year by 2050, according to a National Center for Energy Analytics projection. That raises the question the industry has been dancing around for years—where is all that methanol supposed to come from?

For most of the previous century, making methanol meant building a colossal, centralized plant near a cheap natural-gas supply. A new wave of startups is betting that the old formula is backwards for the low-carbon methanol needed for shipping. Instead of piping stranded methane to a plant, the new idea holds, it’s cheaper to bring a plant to the methane.

Today, Emvolon—an MIT spinout founded in 2021 by Emmanuel Kasseris and Leslie Bromberg—announced the details of an agreement to sell up to US $450 million of the company’s biomethanol and other liquid fuels over a seven-year period to Stamford, Connecticut-based commodities trader Freepoint Commodities. Kasseris says the deal will fund construction of Emvolon’s fleet of modular, container-size plants, which convert methane from landfills and other waste sites directly into ship fuel.

Engine-Based Syngas Methanol Production

Rather than engineering a conventional chemical reformer, Emvolon repurposes an off-the-shelf automotive engine to help produce methanol. Emvolon runs the engine “fuel rich” (meaning more fuel is injected into the cylinders than can be burned with the amount of air in the mix). As a result, the cylinders produce syngas—a mix of carbon monoxide and hydrogen—instead of burning methane all the way to carbon dioxide and water. Syngas is then synthesized into methanol. Kasseris says the approach cuts the capital cost of small-scale chemical production by an order of magnitude compared with a purpose-built reformer.

Each complete system is roughly container-sized and converts about 3,500 cubic meters of methane into 8 tons of methanol a day. Trucked to a landfill, wastewater plant, or flare stack, it turns a gas stream that would otherwise be vented or burned into a liquid fuel that leaves by ordinary tanker truck—no new pipeline required.

A metal box that looks like an ordinary shipping container on the outside could contain machinery that converts the methane emitted by landfills and oil wells into green methanol. Emvolon

Emvolon has already moved from lab demonstration to commercial deployment. The company’s first commercial reformer is going up at a landfill in Humble, Texas, near Houston’s Bush Intercontinental Airport under a joint venture Emvolon and Montauk Renewables signed in 2025. The unit will run at roughly half a ton to a ton of methanol per day to start, Kasseris says, and Emvolon is targeting production to begin in 2027.

Emvolon isn’t limited to projects it develops itself. A landfill or gas-site owner could buy units outright and arrange separate offtake agreements for the produced methanol, Kasseris says. Emvolon can offer anything from equipment and training alone up to a full package of hardware, offtake, and financing—though he expects the company will eventually specialize in one side of that business as it scales.

A Growing Fleet of Methanol-Fueled Ships

Kasseris puts the current count of methanol-capable ships on order or in operation at roughly 400—evidence, in his view, of demand that’s already here. Ships calling at European ports already face the EU’s Emissions Trading System and FuelEU Maritime rules, which price a vessel’s carbon intensity and push shipowners toward cleaner fuel. Kasseris expects Chinese policy to move the same direction; July’s alliance launch and the Maritime Technologies Forum‘s new methanol safety guidelines suggest the regulatory scaffolding is catching up to the hardware.

In addition to being environmentally friendly, green methanol scores points for practicality. It’s liquid at room temperature, easier to store than hydrogen or ammonia, and simpler to synthesize than long-chain synthetic hydrocarbons. Kasseris also notes that methanol isn’t a one-market bet; gasoline blending, industrial buyers, and eventually sustainable aviation fuel can all draw on the same supply.

The modular, at-the-source approach has been gaining adherents for years. WasteFuel, a Los Angeles-based waste-to-fuel developer, introduced a containerized “Methanol Module” in 2022 and has an offtake agreement with Maersk for 30,000 tons of bio-methanol annually. Maverick Synfuels, based in North Carolina’s Research Triangle, has marketed small, co-located gas-to-liquids plants since 2014. Houston-based HyOrc and engineering firm Re:Build Optimation are pursuing similar builds. WasteFuel, Maverick, and HyOrc did not respond to requests for comment from IEEE Spectrum.

Distributed Biogas Methanol Economics

The case for going small starts with feedstock: biogas and landfill gas are low-density and costly to move. ERM, an environmental and engineering consultancy in London, estimates delivered landfill gas costs at $22 per gigajoule, and raw production costs at roughly $9.50 per gigajoule.

A single modular site like one of Emvolon’s costs an estimated $5 million to $20 million, versus $500 million or more for a centralized plant—meaning a regional cluster of sites can match a mega-plant’s output at a fraction of the combined capital and permitting risk.

Whether that math holds once the model moves from a handful of sites to the dozens needed to matter for global shipping remains open. Kasseris says Emvolon’s stated goal is near-fossil-parity pricing without subsidies. He’s predicting that the same bet on standardized manufacturing—which has already paid off for solar panels and batteries–will make the numbers work in Emvolon’s and its competitors’ favor. For an industry looking to replace a century-old fuel supply chain within the next two decades, distributed production may be less a curiosity than a necessity.
