Introduction
Value proposition
More efficient e-methanol synthesis from CO2 and H2
Separation-enhanced reverse water-gas-shift production can improve syngas conversion efficiency and enable more efficient e-methanol synthesis from CO2 and H2. Selective removal of reaction products via EMM or SIENNA technology can increase conversion per pass, reduce recycling energy demand, and lower CAPEX and OPEX.

Groups of innovations
There are no distinct groups of innovations identified within this demo.
Impact
| Impact | Level | Remark |
|---|---|---|
| Energy efficiency | Medium impact | Higher single-pass conversion can reduce recycling energy demand and improve overall process efficiency. |
| GHG emissions | Large impact | When produced from renewable hydrogen and captured CO2, e-methanol can contribute to low-carbon maritime fuel supply and circular carbon use.t from 'Impact' and choose the correct impact level] |
| Air pollution | Medium impact | Methanol use in shipping can support cleaner combustion profiles compared with conventional marine fuels, depending on engine technology and operating conditions. |
| Safety | Limited impact | Methanol handling requires dedicated procedures for toxicity, flammability, storage, and bunkering, building on existing chemical-sector safety practices. |
| Circularity | Large impact | The route reuses CO2 as a carbon feedstock and links renewable hydrogen production to maritime fuel demand. |
| Port city impact | Medium impact | Local or regional production can strengthen clean-fuel clusters and reduce dependency on fossil fuel supply chains. |
| Nature and community impact | Limited impact | Benefits depend on renewable electricity sourcing, CO2 origin, siting, and safe integration with port-industrial activities. |
| Competitiveness | Medium impact | Supports technology leadership in synthetic fuels and creates a stepping stone toward commercial e-methanol supply for shipping. |
Port characteristics
How to implement?
- Step 1
Launch demonstrator and define KPIs for conversion efficiency, energy demand, membrane performance, and product quality
- Step 2
Conduct operational characterization, modelling, lab testing, and data collection
- Step 3
Move to pilot-area simulations and integrated testing with CO2, hydrogen, and downstream methanol synthesis conditions
- Step 4
Validate results against commercial benchmarks and prepare scale-up pathway for port-industrial deployment
- Step 5
Develop offtake, certification, safety, and bunkering arrangements to enable market introduction
What should a port do in the next 3 years?
