E-methanol produced from green hydrogen and captured CO2 is emerging as a key sustainable shipping fuel and chemical feedstock. Efficient electrolysis is the cost-critical enabler.

Membrane Cross-Section

PSU-TiO₂-GO

Lower H2 Input Cost

Methanol synthesis requires approximately 190 kg of H2 per tonne of product. IONZERA's 3x lower membrane resistance reduces the electricity cost of this hydrogen input, directly improving e-methanol economics.

High-Purity Hydrogen Output

Gas crossover below 0.5% H2 in O2 ensures the hydrogen feed meets the purity specifications for methanol synthesis catalysts, minimizing downstream purification requirements.

Scale-Ready Manufacturing

E-methanol projects are being planned at 100,000+ tonne-per-year scale, requiring large electrolyser installations. IONZERA's mesh-free production scales to meet these demands.

The Rise of E-Methanol

Green methanol, also called e-methanol, is produced by reacting green hydrogen with captured CO2 over a catalyst. It is emerging as one of the most promising sustainable fuels for maritime shipping, with major shipping lines ordering methanol-powered vessels. E-methanol also serves as a versatile chemical feedstock and a liquid hydrogen carrier for energy transport.

The economics of e-methanol are dominated by two inputs: the cost of green hydrogen and the cost of captured CO2. Since hydrogen typically represents 60-70% of the production cost, reducing electrolyser energy consumption through more efficient membranes has an outsized impact on e-methanol viability.

Electrolyser Efficiency for Methanol Economics

The stoichiometry of CO2-to-methanol synthesis (CO2 + 3H2 -> CH3OH + H2O) means every tonne of methanol requires approximately 190 kg of hydrogen. At industrial scale:

A 100,000 tonne-per-year e-methanol plant needs roughly 19,000 tonnes of green hydrogen annually

This requires approximately 300 MW of electrolyser capacity operating at high utilization

IONZERA's 3x lower membrane resistance reduces electricity costs at this scale by millions of dollars annually

Lower membrane cost from mesh-free manufacturing further reduces the electrolyser CapEx contribution to methanol production cost

Supporting the Maritime Fuel Transition

With the International Maritime Organization targeting significant emissions reduction by 2030 and net zero by 2050, e-methanol demand is projected to grow exponentially. IONZERA positions electrolyser manufacturers and project developers to meet this demand with a membrane that delivers both the performance and the cost structure needed for competitive e-methanol production.
