Well-to-Tank analysisConventional oil pathways
At the 2010-2020 horizon, alternative fuels will replace some fraction of the current conventional fuels market
The energy that can be saved and the GHG emissions that can be avoided therefore pertain to the MARGINAL production of conventional fuels
Europe is short in diesel and long in gasoline: the “natural” balance between gasoline and middle distillates is stretched
As a result, refinery production of marginal diesel is more energy-intensive than that of marginal gasoline

LH2 is more energy and GHG intensive than CH2
Central reforming requires somewhat less energy than on-site
Electrolysis is very energy-intensive and can only be justified if genuinely renewable electricity is available

Tank-to-Wheels study:Gasoline, Diesel, Natural gas, Hydrogen
For the purpose of this study, a “virtual” vehicle was created, figurableas a VW Golf 1.6 l gasoline (most popular segment of the market)The results do not represent a fleet average
The Fuels / powertrains considered here are :- Technologies 2002 are purely Internal Combust. Engines (I.C.E.)- Technologies assessed for 2010 include : I.C.E. & Fuel Cells
The engine technologies and fuels investigated do not imply any assumptions with regard to their potential market share
ICE hybrid vehicles will be included later

Tank-to-Wheels studyPerformance & Emissions
All technologies fulfil at least minimal customer performance criteriaFor bi-fuel (gasoline-CNG) the vehicle performance decay (12% torque down-shift) is accepted. A dedicated CNG engine, upsized at 2 l. to fulfil the required performances is simulated.
The H2 I.C. engine is simulated as extrapolated from single cylinder present studies : 1.3 liter, already turbo-charged to meet the performances.
“Vehicle / Fuel” combinations comply with emissions regulationsThe 2002 vehicles comply with Euro IIIThe 2010 vehicles comply with EU IV
Direct Injection for gaseous fuels is not simulated as still at the level of research with open issues to be adressed (energy penalty or limited range)

Slide 21
Tank-to-Wheels studyComments : state of the art 2002
H2 ICE : Energy efficiency results from simulation are better than gasoline reference :Reason:- The S.I. H2 engine model is, already in 2002, simulated as downsized and turbo charged (DSTC), while the reference gasoline engine is not.
- The gasoline ICE will include the same technology in the 2010 version(and therefore be more energy efficient)
- The benefit of DSTC will not be accounted twice for H2 in 2010
No GHG are emitted by the H2 powertrain, except the NOx contribution

Tank-to-Wheels studyEvolutions 2002 - 2010
From present State of the Art until 2010, Fuel efficiency evolutions should occur, depending on:
- the maturity of the technology- the specific possibilities and constraints of the fuel
Car manufacturers globally converge towards assumptions :- Port injection S.I. : + 15 % (includ. Downsizing Turbo Charged)- Direct injection S.I. : + 10 %- Diesel : + 6 % ( or 2 %, only, under Particle Trap)- Hydrogen I.C.E. : + 6 % ( D.S.T.C. already accounted as 2002)
- Nat. Gas & H2 : + 1 % supplementary for optimal air - gas mixture

Remarks for ICE
Highest energy use ------------------------------------------------------------------------Lowest energy use
Global Primary Energy Intensity: for all fossil energy sources, used in ICE:
LH2 > CGH2 > Conventional fuels
GHG global impact :Direct use of NG as CNG better than hydrogenHydrogen ICE more GHG-intensive than conventional engines/fuelsElectrolysis worst option unless electricity is from renewable sourceCoal could only compete with CO2 sequestration
Renewable sources obviously give best GHG but…Are there alternative use for these?

Remarks
Global Primary Energy Intensity: for all fossil sources:
LH2/FC ~ conventional ICEs > CH2/FC
GHG global impact :
H2 Fuel Cells, even with H2 from NG, compare favourably with conventional fuels ICE’s
Worst option remains Electrolysis from EU-mix power
Highest energy use ------------------------------------------------------------------------Lowest energy use
ICE hybrids still to be calculated
