6 The refining challenge Crude oil: typically much heavier than product demand LPG Naphtha/gasoline Kero/jet Gasoil/Diesel Heavy fuel oil 20 0 Brent Iran light Nigerian Russian Kuwait Demand Use available crudes: Adapt to quality variations Adapt to different crudes on a day-to-day basis Produce desired products: All products must be on-spec All must be produced at the same time Nothing can be thrown away! And minimise energy, CO 2, environmental impacts, and costs 6

7 Refineries turn crude into multiple fit-for-purpose products Demand (%) or Refinery yield (% on crude) Fuel & Loss (% on crude) 100% 10% 80% 8% 60% 40% 20% 6% 4% 2% LPG Naphtha Gasoline Kero/Jet Gasoil/Diesel Heavy Fuel Oil Fuel & Loss 0% 2010 Simple High gasoline High diesel 0% EU Demand refinery yield Complex refinery yield Achieving this requires complex process technology and hydrogen Reforming to obtain the desired molecules and distribution Residue conversion to crack larger molecules into smaller ones Hydrotreating to obtain the desired product quality (e.g. S removal) More refinery complexity means that more energy and more hydrogen are needed - and typically more CO 2 emissions 7

11 Sulphur reduction options Two options: Remove from fuel Remove from exhaust gas Fuel desulphurisation Exhaust gas cleaning Pros Central treatment Simplified on-board fuel handling when distillate fuel is used SO 2 easily absorbed in alkaline water Low additional energy requirements Favourable economics Cons Complex refining process Increased energy consumption and CO 2 emissions in refining Major Investments for individual projects Higher cost fuel Additional equipment on ship Investment Demonstration of compliance This is the base case option for the CONCAWE EU Refining study 11

12 Low S marine fuels: more than just removing S 1000 ppm S = 0.1% S Road transport fuels Stepwise reduction S level driven by engine exhaust gas after-treatment requirements Hydrodesulphurisation process investments Basic fuel blend composition remains essentially unchanged Data sources: Hart 2011 Worldwide Fuel Specifications, IMO Marine fuels High pressure, high temperature hydrodesulphurisation Technology limit for desulphurising heavy fuel oil Requires major changes in blend composition Switch from residual components to distillates for ECA 0.1%S fuel (equivalent to standard domestic heating oil quality) 12

13 Sulphur Removal Hydrodesulphurisation (HDS) process Treat products with hydrogen Reaction at elevated pressure and temperature Convert embedded sulphur to H 2 S Absorb H 2 S from process gas and convert to elemental S Energy intensive Increased refinery CO 2 emissions Production of hydrogen starting from natural gas (CH 4 ) Carbon in natural gas rejected as CO 2 Picture: ExxonMobil 9-Feb

15 Declining product demand (including biofuels) Total demand including biofuels in EU (Mt/a) LPG Gasoline 500 Petrochemicals Middle distillates 400 Residual marine fuel Residual inland fuel 300 Others 200 (*) JEC Consortium: Joint Research Centre of European Commission, EUCAR and CONCAWE Source: Wood Mackenzie, CONCAWE Basis: JEC* Fleet & Fuels model for road diesel and gasoline; Wood Mackenzie 2011 for all other products European fleet-average CO 2 emissions for new passenger cars: 143 g CO 2 /km in 2010 (actual) 95 g CO 2 /km by 2020 (mandated target) 75 g CO 2 /km by 2030 (assumed) Products demand expected to fall by 137 Mt (19%) between 2005 and

16 Middle distillate / Gasoline demand ratio Increasing distillate/gasoline imbalance Total demand including biofuels in EU (% m/m) LPG Gasoline Petrochemicals Middle distillates Residual marine fuel Residual inland fuel Others MD/Gasoline ratio (RH axis) 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Source: Wood Mackenzie, CONCAWE 10% 19% % 61% Steady decline in total demand but a steady growth in: Percentage of middle distillates, reaching 61% in 2030 Ratio of middle distillates to gasoline, reaching 6.3 in 2030 Increasingly difficult for gasoline-oriented EU refineries to meet this changing demand ratio. 16

17 Steady growth in share of refined middle distillates Distillates demand (fossil only) in EU (% m/m of total refined products demand) 70% 60% 50% 46% 60% Distillate marine bunker 40% Heating oil Diesel (non-road, rail and inland water) Jet/Kero 30% 20% Diesel (road) 10% 0% Source: Wood Mackenzie, CONCAWE Middle distillate refined products are heavier than gasoline but lighter than heavy fuel oil Total European refined middle distillates demand does not grow in absolute tonnage Share of distillates in total refined product market continues to increase, reaching 60% in Contrasting market tonnage trends: demand for jet fuel and distillate marine fuel Switch from residual marine fuel to distillate marine fuel in ECAs adds about 14 Mt to distillate demand from 1/1/2015 demand for heating oil and road and non-road diesel 17

19 Refining CO2 emissions will increase These figures assume constant refinery energy efficiency frozen at the 2008 level Demand Demand IMO general bunker 0.5%, Ferry bunker 0.1% Demand SECA bunker 0.1%, switch to distillate Non-road Diesel 10 ppm S Inland Waterway Gasoil 10 ppm Demand Demand-related Quality-related SECA bunker 1.0% Demand 2010 Base case Note: Graphs and figures from CONCAWE report awaiting publication EU Refineries CO 2 emissions (Mt/a) Biggest increases in EU refinery CO 2 emissions are caused by: 2015 switch to 0.1%S distillate bunkers in SECAs 2020 switch to 0.1%S distillate bunker for EU ferries and 0.5%S IMO general bunker. Declining demand post-2020 reduces CO 2 emissions from the 2020 peak. Refinery energy efficiency improvements would offset these increases. 19

20 Substantial investment requirements Announced projects $21billion IMO general bunker 0.5% Ferry bunker 0.1%, switch to distillate Demand SECA bunker 0.1%, switch to distillate Non-road Diesel 10 ppm S Inland Marine Gasoil 10 ppm Demand SECA bunker 1.0% FQD PAH 8% Demand Note: Graphs and figures from CONCAWE report awaiting publication. G$ (2011) Announced EU refining project expenditure estimated at $30 billion Estimated total investment of $51 billion would be required by 2020 to fully meet product demand and quality changes (including low sulphur marine fuel) Additional $21 billion over and above the announced projects Declining demand post-2020 will lead to under-utilisation of new-build capacity This could have a negative influence on investment decisions prior to

21 Refinery CO2 emissions (Mt/a) Refinery investment (G$) On-board scrubbing lowers refining investments & CO 2 IMO Investments and refinery CO 2 emissions are estimated in two scenarios: 19 G$ Scrubbers IMO: All marine fuel ex-refinery must meet IMO specs. No on-board scrubbers. Scrubbers: All ships are equipped with on-board scrubbers from 2015 onwards. Base Case IMO 17 Mt/a CO 2 The refinery investment for the 100% scrubbers case would be reduced by $19 billion in 2020 The 100% scrubbers case would avoid a 17 Mt/yr increase in refinery CO 2 emissions This would be partially offset by increased CO 2 emissions from scrubber energy consumption Scrubbers Overall well-to-propeller CO 2 emissions still expected to be largely in favour of scrubbers Base Case Note: Graphs and figures from CONCAWE report awaiting publication. 21

23 Conclusions 2010 and 2012 changes to S content of marine fuels: Some limited crude slate optimisation Blending & segregation Longer term ( ): Unprecedented step changes & major investments needed Refiners unlikely to be able to supply market in the same way as today Not currently possible to predict how the market will react Much depends on factors such as: The rate of ECA growth The application of abatement technology The use of alternative fuels, e.g. LNG Overall CO 2 emissions impact of marine fuel S reduction is significant There is no single solution keep all routes to compliance open 23 23
