Well-to-Wheel emissions: ICE - Petrol and Diesel Well to Tank Tank to Wheel Extraction Refinery Transport Dispensing Use: ICE Tank-to-Wheel emissions high due low efficiency ICE Well-to-Tank very efficient: about 15% extra 11

Well-to-Wheel emissions: Hydrogen Well to Tank Tank to Wheel Extraction Nat. Gas H 2 production: SMR Transport LH 2 Dispensing 700 bar Use: ZEV (FC) Tank-to-Wheel zero-emission & high vehicle efficiency Well-to-Tank is energy intensive 13

Summary Key factors for environmental impact of Hydrogen are: Volume: Market penetration of H 2 Vehicles Relative WTW reduction: Production route H 2, application of CCS H 2 versus ICE - Well-to-Wheel: Relative emission reductions substantial: 30%-70% per ICE replaced Large reduction only in case of SMR with CSS THRIVE scenario results: Given low H 2 penetration, only visible after 2030 If successfully introduced, H 2 provides a large step towards achieving climate targets around 2050 23
Conclusions on contribution of Hydrogen Good prospects for significant Well-to-Wheels CO 2 emission reduction, especially if proper incentives are introduced for clean and green hydrogen Indication of expected progress until 2050 seems promising 100% H 2 penetration needed, including CCS to meet climate targets Biofuels & vehicle efficiency (ICE) Max reduction potential H 2 (excl/incl CCS) Source: King Review, 2007 24
