All e1 Marine generators produce fuel-cell-grade hydrogen at >99.97% purity, meeting ISO 14687 standards and ensuring compatibility with all marine PEM fuel cells.
This gives operators full flexibility in system design and fuel cell partner selection, with proven integration across a broad range of leading suppliers.
Fuel cell Compatibility
Ports face mounting pressure to decarbonize, but grid access is often unavailable, unreliable, or prohibitively expensive. The Clean Power Generator (CPG) addresses this directly, providing a flexible, containerized, grid-independent power solution built around e1 Marine's methanol-to-hydrogen technology.
Each CPG unit delivers up to 250 kW and is scalable to 3 MW, supporting cold ironing for berthed vessels, charging battery-electric vehicles, vessels, and port equipment, and emergency backup power. Its mobile format enables rapid deployment wherever demand arises – no permanent infrastructure required.
CPG – Clean Power Generator
Fuel cells are the most energy-efficient device available for extracting power from fuels. Fuel cells are maximally efficient at 60%, thus 37% more efficient than a diesel engine.
A fuel cell will directly convert the chemical energy in hydrogen to electricity, with pure water and potentially useful heat as the only byproducts. Hydrogen-powered fuel cells are not only pollution-free, but they can be more efficient than traditional combustion technologies.
Marine class fuel cells provide clean zero-emission power with up to a multi-megawatt scale for both prime propulsion and auxiliary power applications. Fuel cells offer marine operators power solutions that meet IMO guidelines – right now.
Fuel Cell Power: Clean Zero-Emission Power – (Solving the IMO problem)
M/V Hydrogen One
The world’s first methanol to hydrogen fuel cell towboat.
With construction set to begin in 2026, M/V Hydrogen One is set to join the Maritime Partners fleet, to meet the pressing demand for sustainable towboat operations. The vessel will be IMO 2030 compliant, meet the USCG’s Subchapter M requirements, and have an operational range of 850 miles before refueling.
The missing link to fuel cell power adoption.
Hydrogen is a challenging fuel; it is expensive to transport and store. It is also nearly impossible, to achieve an acceptable vessel range from liquified or compressed hydrogen due to onboard storage requirements. These challenges mean that marine and port operators are facing significant economic, technical, logistical, and range hurdles when introducing hydrogen and fuel cell power technology to their fleets.
e1 Marine can solve these challenges.
Our methanol to hydrogen generator products are simple, robust, cost-effective, and produce pure fuel cell grade hydrogen anywhere you need it, in real-time, as required by your fuel cell power solution. No expensive and volume-intensive high-pressure hydrogen storage is required.
Solving “The Hydrogen Challenge” for Maritime Applications
e1 Marine Methanol to Hydrogen Generator
Scalable, mobile, and standalone hydrogen generation.
The e1 Marine methanol to hydrogen generator with its patented membrane purifier, produces hydrogen – when and where it is needed. No need for high-volume electrical power. Once running, a standard hydrogen fuel cell running on e1 Marine hydrogen produces its own electrical power – creating a far more efficient operating range for the vessel.
Methanol as a Marine Fuel - safe storage, safe transport, renewable future
Methanol is an ideal marine transportation fuel. It has a high energy density and is widely available in ports globally. Handling methanol utilizes familiar fuel logistics and safety protocols, and methanol offers safer and less expensive fuel storage than compressed hydrogen. When using methanol as a hydrogen carrier, there is no need for expensive, dangerous, high-pressure hydrogen transportation and bunkering.
Hydrogen can now be generated onboard or portside using a feedstock of methanol and DI water.
Methanol enriched with water has up to six times the energy density of compressed hydrogen, providing fuel cell power solutions with significantly reduced cost, increased safety, efficiency, and operational range.
Methanol has a renewable zero-emission future, just like renewable hydrogen and RNG.
e1 Marine's hydrogen generator products are easily integrated with advanced marine fuel cell power solutions.
They are adaptable for use in stationary power applications in ports and terminals, including cold ironing, reefers, and backup power, as well as onboard the vessel as primary propulsion and auxiliary power systems.
Applications
Today's maritime applications demand durable, high-performance, and compact systems.
Hydrogen at work - safe storage and safe transport.
Readily available worldwide, methanol offers far greater hydrogen density for safer, cheaper storage than high-pressure fuel-grade hydrogen. There is no need for expensive, dangerous, high-pressure hydrogen transportation and bunkering. Onboard hydrogen can now be generated using methanol mixed with water - sourced from the very water the vessel sails in.
