  1. 1. Hydrogen Fuel Cell VehiclesResearch and Development<br />Michael Lewis<br />April 27, 2011<br />
  2. 2. Why Hydrogen and Fuel Cells?<br />Ultimate Goal is to reduce emissions and dependence on foreign oil<br />Hydrogen is abundant and can be produced from a variety of feedstock<br />Natural Gas Reformation<br />Biomass Gasification<br />Renewable Electrolysis<br />Hydrogen is a carbon free fuel<br />Hydrogen Fuel Cells are more efficient than traditional technologies and have zero emissions<br />
  3. 3. Current Challenges<br />If it was easy…<br />Hydrogen production, distribution, and storage<br />Reduce cost on all fronts<br />CO2 sequestering  Zero emissions<br />Innovative materials based storage is promising<br />Fuel Cell cost and durability<br />Advances in membrane and component technology are ongoing and leading to decreased cost and increased reliability<br />Current political environment is less favorable than in the past<br />
  4. 4. CEM’s Role<br />Address Challenges through<br />Technology Demonstration and Implementation<br />Increase Commercialization through<br />Technology Transfer to Industrial partners<br />Balance of Performance versus Cost<br />Provide Education to<br />Manufacturers and Public<br />Disclaimer: This is not a fuel cell vehicle.<br />
  5. 5. Early Hydrogen Fuel Cell Work<br />Plug-In Hybrid Fuel Cell Bus demonstration and evaluation (2007-2008)<br />Excellent learning platform that has provided knowledge and experience for current and future programs<br />Installed first permanent Hydrogen Fueling Station in Texas<br />Unique capability to produce and deliver compressed hydrogen for current and future hydrogen vehicle programs<br />
  6. 6. Current and Ongoing Work<br />Extended Range Hydrogen Utility Vehicle<br />Goal: To significantly increase range without reducing vehicle performance<br />Hydrogen fuel cell retrofit of existing battery powered utility vehicle<br />Two vehicles in 8 months<br />Sponsored by Defense Logistics Agency and NAVSEA-CRANE<br />Currently performing successfully halfway through 12 month demonstration at Warner Robins AFB<br />Project Partners: <br />Success in this program has led to other DLA opportunities.<br />
  7. 7. Current and Ongoing Work<br />Austin Demonstration of Plug-In Hybrid Fuel Cell Transit Bus<br />12-month revenue service under Capital Metro<br />Goal: Reduce NOx and further commercial acceptance of hydrogen bus and fueling infrastructure<br />Proterra Hydrogen Fuel Cell Hybrid bus<br />Fuel cell “plug-in” hybrid using advanced Li-ion batteries<br />Increases fuel economy by 2-3X over conventional diesel buses<br />To be fueled using UT-CEM hydrogen station<br />Program onset will included station upgrades to reformer and storage capacity<br />Funding provided by TCEQ and FTA (through CTE)<br />UT-CEM is the prime under TCEQ funding<br />Program management, as well as bus and station evaluation<br />Project Partners:<br />GTI, CTE, Capital Metro, Proterra<br />
  8. 8. Upcoming and Future Projects<br />Hydrogen Powered Terminal Tractors<br />Goal: Identify onboard hydrogen storage and power system designs to increase performance of current state-of-art terminal tractors<br />Sponsored by Defense Logistics Agency<br />Phase I Design:<br />Capacity of Texas PHETT is baseline vehicle for retrofit<br />Plug-In Hybrid Electric Terminal Tractors using lead-acid batteries and a diesel gen-set<br />Dual parallel Fuel Cell modules with 700 bar gaseous hydrogen storage<br />Adds reliability and redundancy to power system<br />Provides opportunity for increased hydrogen storage while still maintaining compatibility with more common 350 bar infrastructure<br />Phase II Proposal submitted March 2011<br />Leveraged success of Hydrogen Utility Vehicle Program for similar retrofit of a commercial terminal tractor with DLA.<br />
  9. 9. Upcoming and Future Projects<br />Electric Transit Bus with On-route Charging<br />Goal: Demonstrate transit technologies that reduce energy consumption and GHG emissions<br />FTA sponsored TIGGER award<br />Transit Investment for Greenhouse Gas and Energy Reduction<br />Partners: CTE, Proterra, Star Metro (Tallahassee, FL), VIA (San Antonio, TX)<br />Star Metro – Conductive on-route charging with optional fuel cell package<br />VIA – Inductive on-route charging<br />CEM’s role: data collection and evaluation, technical program management<br />Opportunity to collect data / knowledge on advanced batteries for future projects and other applications<br /><ul><li>All-electric derivative of the Proterra fuel cell transit bus
  10. 10. 70 kWh of Li-ion batteries
  11. 11. Rapid charge in about 8 minutes (or less), 60% to 70% SOC swing
  12. 12. Gives about 20 mile range
  13. 13. Requires on-route charging infrastructure</li></li></ul><li>Commercialization / Education<br />Hydrogen Utility Vehicles and Terminal Tractors<br />Goal: Develop hydrogen fuel cell utility vehicle (or terminal tractor) that balances cost and performance for commercial applications<br />Potential market exists at sites currently using fuel cell lift trucks<br />Hydrogen refueling structure is already in place<br />Over 1500 lift trucks in operation at more than 40 sites throughout U.S.<br />DLA vehicles were subject to demanding requirements (range, gradeability, duty cycle)<br />Commercial Utility Vehicle Design Approach<br />Keep cost down by using vehicle’s stock lead-acid batteries with 1-2 kW fuel cell and 0.5-1.0 kg of H2<br />Hydrogen Fuel Cell upgrade cost: $8,000 to $12,000 (current vehicle cost ~$10,000)<br />Commercial Terminal Tractor Design Approach<br />Keep cost down by using single fuel cell power module and<br />Balancing performance and customer needs<br />CEM will present Commercial Utility Vehicle potential to Columbia ParCar in upcoming months<br />Capacity of Texas plans to contract CEM for technical assistance through their TCEQ funding for development of a Zero Emissions Terminal Tractor (ZETT)<br />Modeling tools and experience  Education and Technology Transfer<br />
