Green Hydrogen for Maritime Fuel Cells

Hydrogen fuel cell vessels require reliable, cost-effective hydrogen bunkering infrastructure. IONZERA-equipped electrolysers at ports and terminals produce the green H2 that zero-emission shipping demands.

Lower Bunkering H2 Cost

Port-side electrolysis with IONZERA's 3x lower membrane resistance reduces the cost of hydrogen produced for maritime bunkering, improving the economics of fuel cell shipping.

Modular Port Infrastructure

IONZERA's compact stack design enables modular electrolyser installations that can scale with growing port hydrogen demand as the fuel cell vessel fleet expands.

Proven Material Reliability

Maritime hydrogen supply demands absolute reliability. IONZERA's 2.7 MPa tensile strength and chemically stable PSU-TiO2-GO matrix support continuous operation for critical port infrastructure.

The Maritime Hydrogen Opportunity

International shipping accounts for approximately 3% of global CO2 emissions, and the International Maritime Organization has adopted increasingly ambitious decarbonization targets. Hydrogen fuel cells offer a pathway to zero-emission shipping for coastal vessels, ferries, tugs, and smaller cargo ships, with longer-range applications served by hydrogen-derived fuels like ammonia and methanol.

All hydrogen-powered maritime solutions require efficient production infrastructure at ports and bunkering terminals. Alkaline electrolysis using IONZERA membranes provides the large-scale, cost-effective green hydrogen production that maritime decarbonization demands.

Port-Side Hydrogen Production

Producing hydrogen at or near ports using on-site electrolysis eliminates the cost and complexity of long-distance hydrogen transport:

Shore-side renewable energy from solar, wind, or grid connections powers the electrolyser directly
IONZERA's low area resistance maximizes hydrogen output per kWh of electricity consumed
Modular electrolyser installations can start small and scale as the fuel cell vessel fleet grows
Port authorities can offer green hydrogen bunkering as a competitive advantage to attract zero-emission shipping lines

Beyond Direct Hydrogen: Maritime Fuel Pathways

While direct hydrogen is optimal for short-range maritime applications, longer routes increasingly look to hydrogen-derived fuels. Green ammonia and e-methanol, both produced from electrolytic hydrogen, are leading candidates for deep-sea shipping fuel. IONZERA-equipped electrolysers serve all of these pathways, providing the efficient hydrogen production that underpins every maritime fuel alternative.

G-Hexa engages with port authorities, maritime fuel infrastructure developers, and naval architects to provide membrane solutions for port-based hydrogen production systems.
