Methanol is used as a fuel already today
Commercial use of methanol for ICE only in China
Doc.ID: Revision: Status:© Wärtsilä14/
Fuel availability: Methanol Infrastructure Advantage
Annual production of methanol ~ 65 million tonsProduction utilization ~ 65-70%Annual growth ~ 7 million tons ( only China)

Wärtsilä Methanol-Diesel retrofit solution
On-engine scope is limited to exchange of cylinder heads,fuel injectors and fuel plungers in existing fuel pumps
A common rail system for methanol injection will be addedon the engine
In addition to the Engine related conversion includes the conversion kit a stand-alone high pressure methanol pumpwith belonging oil unit for supply of sealing oil and control oilto the fuel - beside an update of the automation system.injectors.

Tests on Methanol – Initial testing of Wärtsilä MD concept
Optimal heat release Lower Exhaust Temperatre
Reduced NOx Same efficiency as diesel
CO, THC acceptable ( < 1 g/kWh)Formaldehyde emissions low ~ much below TA-luftNo Formic acid detected in exhaust gases
Engine: Wärtsilä Vasa 32

Tests on Methanol – Recent testing of Wärtsilä Sulzer Z40S-MD
Repeated tests on Sulzer Z40S-MD show same trends as the pre-tests on Wärtilä Vasa 32:
Reduced NOx / PMReduced exhaust temperature Same or Better efficiency
Tier III 2,6 g/kWh
Tier II 10,5 g/kWh
