Pioneering alternative fuels – marine methanol
MARI JONEDelivered April 2016
MARI BOYLEDelivered August 2016
Simplest hydrocarbon Optimal hydrogen carrier
Stable in ambient conditions
Water solventBlue, green, gray,
black Multi source mixable
Rationale on a molecular level
Summary: Methanol as Fuel
EASY TO TRANSPORT AND AVAILABLE
ALREADY TODAY AT +90 PORTS
EASY TO STORE ON BOARD. NO CRYOGENICS
INVOLVED.
PROVEN FUEL USED IN TRANSPORTATION SINCE
1970
MINOR MODIFICATION NEEDED COMPARED TO
OTHER ALTERNATIVE FUEL
TIER III COMPLIANT WITHOUT USE OF EGR
AND SCR
VARIED FEEDSTOCK INCLUDING BIOMASS
AND RECYCLED CO2 FOR FUTURE COMPLIANCE
supply independent on proprietary / oligopolized infrastructure
transportation, storage and bunkering works with existing infrastructure
fragmented supplier industry creates a functioning market
seamlessly future proof
Methanol provides better optionality

IMO CII
• Technical (i.e. design): Energy Efficiency for Existing Ships (EEXI) - EEDI applied to existing ships
• Operational: Enhanced SEEMP (Ship Energy Efficiency Management Plan)with mandatory Carbon Intensity Indicator (CII) rating scheme (A-E)
• Measures consolidated into a singlepackage; the outcome is a finelybalanced political compromise

Methanol provides immediate compliance with substantial net GHG reductions, coupled with a strong futureproof pathway, supporting a
CO2equivalent approach

Methanol production routes
Renewable CO2: from bio-origin and through directair capture (DAC)
Non-renewable CO2:from fossil origin, industry
Source: IRENA

Multiple pathways and sub-verticals…
Notes: MeOH = methanol. Costs do not incorporate any carbon credit that might be available. Current fossil methanol cost and price are from coal and natural gas feedstock in 2020. Exchange rate used in this figure is USD 1 = EUR 0.9.

…mean less price volatility and better visibility

Heatmap of methanol applicability – ARA scenario
• Most midrange shipping markets havevessels with over-dimensioned tankcapacity, which allows them to bunkermethanol instead of HFO/MGOwithout serious adjustments to thebunker frequency, sailing pattern, ortank capacity/ship design
• For shipping markets with point-to-point sailing patterns and/or shortdistances methanol is certainlyfeasible, however it may compete withother alternative green fuel optionssuch as hydrogen
• Inland shipping appears promising formethanol, though this segment alsomay compete with e-diesel, hydrogenor battery-electric propulsion

Methanol bunkering & infrastructure
• Much of the required infrastructure is already in place
• Similar to bunkering distillate fuel
• A number of pilots have significantly contributed to the build up in knowledge and understanding of how methanol is safely handled and performs
• Both new builds and retrofits are economically viable
• Planning large-scale methanol bunkering demonstration by May in a major European Port
www.methanol.org/join-us
Experience shows methanol is efficient and available
• As much of the required infrastructure is alreadyin place, retrofits can be readily considered…
• …One of the main reasons so many successfulpilots have already been completed
• The molecular structure allows for much moreefficient combustion, giving way to furthertechnical efficiencies at the main propulsion unitlevel
• An efficient H2 carrier for future fuel platformssuch as fuel cells, converting methanol to H2onboard
