Slide 125 Aug 2009 Linde Comments to CEC 29 September 2009

Slide 225 Aug 2009 There are some advantages to hydrogen fuel cell vehicles Batteries weigh more Batteries take up more space Batteries are poor at GHG reduction Batteries cost more

Slide 325 Aug 2009 Infrastructure – Path Towards Commercialization Advances in Infrastructure -- Linde perspective Release A refueling Ionic technology Product Portfolio Cost reduction

Slide 425 Aug 2009 Advances in Infrastructure Release A Refueling  280 Nm³/h, 2,400 Nm³/h in booster mode  Initial commissioning 05/2009  Station Opening 06/2009 OMV Stuttgart, Germany  240 Nm³/h, 1,200 Nm³/h in booster mode  In operation since 05/2008  Number of refuelings: 6,000 GM Dudenhofen, Germany  240 Nm³/h, 1,200 Nm³/h in booster mode  In operation since 10/2008  Number of refuelings: 350 TOTAL Berlin, Germany

Slide 525 Aug 2009 Advances in Infrastructure - Ionic Technology for the material handling market (250 and 350 bar )  Works like conventional piston compressor  Solid piston is replaced by ionic liquid  Advantages: -Nearly 100% volumetric efficiency -Nearly isothermal compression -Contamination free gas compression -Abrasion free -Excellent conversion of electrical energy into compression work -Perfectly gas tight system  The compressor provides: (i) low energy consumption and (ii) high durability  H2 compression of up to 900 bar  250 or 350 bar  Continuous fast fueling with 20 kg/h, in booster mode up to 70 kg/h Ionic Compressors – Basic factsProduct example: Ionic Fueler 42 FLT

Slide 625 Aug 2009 Advances in Infrastructure - Reduction of captital equipment and operating costs Example – Ionic Fueler Maintenance OPEX CAPEX Ionic Compression Conventional 32 % 48 % 20 % 45 % 9 % 18 % -43 % -7 % -53 % 72% 100 %  lower investment costs  better efficiency  larger maintenance intervals lead to better economics of ionic compressor system -28 %

Slide 725 Aug 2009 Advances in Infrastructure Cost Reduction Cars per day – [#] TCO – [USD / kg, %] Focus – TCO of 700 bar technology % 5

Slide 825 Aug 2009 Critical Next Steps Large Scale Infrastructure and Industrial Production? Time H2 vehicle fleet & H2 FS penetration % Demand (H 2 -vehicles) 0 Supply (H 2 -Fueling stations)

Slide 925 Aug 2009 Critical Next Steps There‘s more than one way to minimize the “loss making steps“ … Time H2 vehicle fleet & H2 FS penetration % Supply (H 2 -Filling station) Demand (H 2 -vehicle.) 0 Faster ramp- up of car park in catchment area Modular station design: e.g., additional storage bundles e.g., upgrade to pre-cooling 1 2 Relocate small station 1 Build large station 2

Slide 1025 Aug 2009 Commercialization will be reached through Government – Industry Partnership  Deployment of retail stations have some challenges…these can be overcome  Over the next several years, with additional station deployments equipment providers will continue to improve efficiency and reduce cost  Government support is critical to achieving profitable commercialization
