How methanol can support maritime electrification
By Dave Lee, Executive Director at e1 Marine and VP of Innovation & Technology at Maritime Partners
Shipping's energy transition is moving from ambition to implementation, and that is where the real complexity begins
Electrification is increasingly central to how vessels, ports and shipyards approach decarbonization. As of mid-2025, slightly more than 1,000 battery-equipped vessels were operating globally, with roughly 550 more on order. But the market is not moving towards one uniform all-electric model: around 65% of those vessels are hybrids, about 17% are plug-in hybrids and around 17% are fully electric.1
Batteries, fuel cells, shore power and hybrid propulsion are not separate technology pathways. They are parts of the same energy architecture, one that must match power demand, operational profile, fuel availability, charging access and local grid capacity. Electrification does not remove the need for energy; it changes how that energy is stored, generated, managed and delivered.
Battery-electric systems make sense in the right applications. For short, fixed routes with reliable charging and modest energy demand, they offer a clean route away from diesel. But many vessels need longer range, higher endurance or greater operational flexibility than battery-only systems can provide. Ports face a similar squeeze: shore power depends on reliable electricity being available where vessels need it, while cargo handling equipment, drayage vehicles and battery banks inside the port fence are electrifying faster than fixed grid infrastructure can always support.
This is where methanol-to-hydrogen has a role to play.
At e1 Marine, our focus is on generating fuel-cell-grade hydrogen from methanol and water, onboard or onsite, on demand. Rather than storing large volumes of compressed or liquefied hydrogen, our reformers use methanol as a liquid hydrogen carrier and produce hydrogen where it is needed, ready for use with PEM fuel cells to power propulsion, auxiliary loads, hotel loads, port operations and battery charging.
Methanol is not a detour from electrification. It is one of the ways electrification becomes practical where range, infrastructure and power availability remain real constraints.
Electrification needs more than batteries
A battery-electric vessel depends on the battery, the charging infrastructure, the grid connection and the operating profile all working together. Where that alignment does not exist, operators need another way to deliver clean electrical power without returning to diesel generators.
Fuel cells can play a complementary role, generating electricity from hydrogen with zero NOx, SOx and particulate emissions at the point of use. Their adoption has been constrained by the difficulty of supplying hydrogen where it is needed: compressed hydrogen requires high-pressure storage, liquid hydrogen requires cryogenic handling, and both demand supply chains that are not yet available at the scale maritime needs.
Methanol changes the order of the problem. It is already handled as a liquid fuel, stored at ambient conditions and reformed into hydrogen at the point of consumption. That creates a bridge between today's fuel logistics and tomorrow's electrified vessel and port operations.
Closing the battery range gap
One of the clearest use cases is range extension. Battery-electric vessels are limited by energy density. For short harbor or inland operations, that may not be a problem. For workboats, explorer vessels and marine leisure craft that need longer runtimes or more flexible operating profiles, it quickly becomes one.
A methanol-to-hydrogen reformer can sit at the center of a range-extender architecture. The vessel still uses batteries, but the reformer and fuel cell provide onboard generation to recharge or support them during operation, underway or at anchor, making battery-based systems more useful where energy density, runtime or charging access would otherwise limit adoption.
Fuel cells need a practical hydrogen source
Fuel-cell deployment has moved past small-scale demonstrations. Projects like the 360 kW Sea Change ferry in the United States and China's 500 kW Three Gorges Hydrogen Boat No. 1 proved the concept could work at sea. The scale has since shifted: Torghatten Nord's 6 MW PEM fuel-cell order for two Norwegian ferries signals fuel cells now being procured at commercial propulsion scale, not just tested at it. 2 The priority is no longer proving that fuel cells can provide marine power, but ensuring hydrogen can be supplied safely, reliably and practically in service.
e1 Marine's core technology is the reformer. The S-Series and M-Series generators convert methanol and deionized water into high-purity hydrogen for fuel-cell power. The S-Series supports smaller-scale applications, including 1-10 kW power solutions and range-extender use cases, while the modular M-Series can support megawatt-scale fuel-cell propulsion and auxiliary power.
e1 Marine does not need to own every part of the electrified powertrain. Our reformers produce fuel-cell-grade hydrogen at more than 99.97% purity, meeting ISO 14687 requirements, which gives shipyards, integrators and operators flexibility in system design and fuel-cell partner selection. It is a practical form of electrification: a way to use fuel cells without waiting for hydrogen bunkering infrastructure to mature.
For projects that need a packaged solution, the M2Power 250, developed with PowerCell, combines e1 Marine's M30 reformer with PowerCell fuel-cell technology in a single onboard unit delivering 250 kW of net power. Reformers, fuel cells and batteries behave differently, and in a hybrid system those differences must be controlled safely and predictably. The M2Power 250 packages much of that integration work into one solution with one interface, giving owners and yards a more straightforward route to methanol-to-hydrogen fuel-cell power.
Supporting port electrification
The same principle applies onshore. Shore-power capability is only part of the equation: ports also need enough clean, resilient power at the right time and in the right place, and that gap is widening as shore-power requirements expand faster than infrastructure. DNV's analysis found that only 3% of global ports visited by vessels above 5,000 GT currently offer shore-power facilities. Even across the EU, China and California, where regulation and incentives are pushing hardest, the figure rises to only 5%.3
Vessel readiness is ahead of it. For example, by April 2026, 4,136 vessels, nearly 4% of the global fleet of around 116,000 ships, had shore-power connections installed. Vessels, ports and regulators are all moving towards electrified operation, but grid capacity and connection infrastructure aren't always in place when projects need them.4
e1 Marine's port-side systems provide deployable power where grid access is limited, delayed or unreliable. The e-Nomad is a CE and ATEX certified containerized unit that uses methanol-to-hydrogen generation and a fuel cell to deliver up to 140 kW of grid-independent electricity for hotel loads, equipment charging and temporary or remote power. The CPG, or Clean Power Generator, extends the same principle to shore power, charging for battery-electric vehicles, vessels and port equipment, and emergency backup, with each unit delivering up to 250 kW and scalable beyond.
This is not an argument against shore power. It is an argument for making port electrification more resilient where permanent connections are unavailable, delayed or insufficient.
Making electrification operational
Maritime decarbonization will not be delivered by one technology. The task now is to make the systems operational: closing the range gap for battery-electric vessels, giving fuel cells a practical hydrogen source, and helping ports provide clean power where the grid cannot yet deliver it.
At e1 Marine, our role is to get hydrogen to work. That starts with methanol reforming, but the purpose is broader: supporting the electrification of vessels and ports by making clean hydrogen available where it is needed, when it is needed. We are already putting this thinking to work on the water, and we will have more to share soon.
That is where methanol-to-hydrogen can make the difference: not as an alternative to electrification, but as one of its practical enablers.
