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