The new MAN B&W ME-LGIP engine
Regulation – a driving factor for engine development
Today, focus is on SOx and NOx:
– NOx reduction is achieved with EGR and SCR
– SOx reduction is achieved with MGO, LFSO, scrubber, LNG, methanol and LPG
In the future, we will see a growing focus on CO2, methane slip and VOC:
– 40% reduction of carbon intensity per transport work by 2030 and 70% by 2050 compared with 2008
– 50% reduction of greenhouse gas emissions from ocean shipping by 2050 compared with 2008
– Reduction of methane slip emissions Diesel cycles
– Reduction of VOC emissions ME-LGIP
Carbon free fuels will be mandatory to meet the 2050 goal
Our dual fuel done right engine technology is well suited to support such goals

Ammonia, NH3 as green fuel produced with renewable energy
Ammonia is the logic option
NH3 advantages as green fuel:
• No carbon. Clean combustion without CO2 or
carbon
• Can be produced 100% by electrical energy
• Can easily be reformed to H2 and N2
• Can be stored with high energy density at < 20 bar
• Low risk of fire. Relatively specific ratio of NH3
and air (15-25%) is required to sustain combustion
Public
Ammonia has better power density than Hydrogen and does not have to
be kept at extremely low temperatures or under high pressure to be
stored and transported
Density P-to-X
Technology Pressure Temperature Safety
(Gje/m3) Efficiency
Liquid H2 Ambient -254 4.8 68% Explosive, Cryogenic
Pressurized H2 700 Ambient 2.8 76% Explosive, very high pressure
CH4 Ambient -163 11.4 56% Explosive, Cryogenic
MeOH (CH3OH) Ambient Ambient 8.2 54% Toxity, but much industrial experience
NH3 Ambient -33 6.8 65% Toxity, but much industrial experience
CO2 sourcing (for CH4 or MeOH) requires a carbon capture unit at
the power plant, with the additional disadvantage of decreasing
round trip efficiency and not capturing all CO2 produced. (ISPT, P2A, 2017, p.31)
Source: Institute for Sustainable Process Technology, Power-to-Ammonia, 2017, p. 31, Power-to-X (P-to-X) efficiency represent the amount of energy maintained when power is converted to the end-product. Losses
in an engine in following use is not included. This is a SGRE Estimate based on ISPT data. The estimate has been made by assuming the X-products are converted back into power with an energy loss of 50%.

This engine type can be modified to burn ammonia as well.
• Development time of an
ammonia engine 2-3
years
• We will be ready when
the market comes
• Efficiency > 50%

PublicConclusion
Propulsion solutions on short term:
• New fuels with lower CO emisson will be needed to meet EEDI
2
• To increase the efficiency; solutions like PTO, WHR will be more common
Propulsion solutions on long term:
• Two stroke engines will remain as the most dominating propulsion solution
• Carbon free produced methanol, ammonia, LNG and biofuels will be available
• All above fuel types can be burned in the 2-stroke ME-C, ME-GI or ME-LGI engine
• Engine Efficiency above 50% ( 60% incl. WHR & PTO )
Development of an ammonia fuelled ME-LGI engine:
• History shows that ammonia works as an engine fuel.
• Engine development will be done when the market comes.
• Development time is estimated to 2-3 years.
