How we plan to develop this field?
Vision of role CEM can play
Who might our partners be
Near-term steps to achieve the vision
Key challenges
Longer term considerations
CEM’s Role in Vehicle Research
Predictive modeling and simulation
Prototype vehicle design and testing
Advanced technology demonstration
and assessment
Outreach, Education, and
Technology Transfer
Dynamic power systems modeling
Quickly evaluate vehicle configurations and
Customizable components and controllers
Avoid build and test approach
Proven ability to match vehicle
performance and energy consumption
within 5-10%
PRC Campus – Hybrid Mode Full Weight
For Example: Long Beach Transit
FTA TIGGER award for all-electric bus fleet
Implement 10 electric buses for dedicated
circulator route
CEM’s modeling and simulation was critical to
– Formulating the bus RFP
– Determining optimal charging scenarios
Bottom line is Cost/Mile
– CEM modeling is helping LBT determine the
best approach for their application
Example: Onboard Range Extender or
En-route Rapid Charging?
CEM involvement on both fronts – fuel cells and rapid
CEM vision is to quantify the pros and cons of both
approaches and determine the best approach for transit
CEM Strengths/Niche
Highbay and machine shop
Skilled technicians and expert
engineering staff
Access to UT professors and students
First and only permanent hydrogen
fueling station in Texas
Dedicated hydrogen vehicle lab
Vehicle manufacturers
–Proterra, Capacity of Texas, ZeroKar, Mahindra-Ampere
Battery, fuel cell, and storage manufacturers
– Hydrogenics, Ballard, Valence Technologies, Vulcore
Non-profit agencies
– Center for Transportation and the Environment, Gas
Technology Institute
National laboratories and government agencies
Vehicle Applications
Light-duty and heavy-duty vehicles
Autonomous and unmanned vehicles
Energy storage and fuel conversion
• Batteries, high pressure tanks,
compressors, reformers
Prime movers and vehicle architecture
• Fuel cells, hybrids, motors
Vehicle Challenges
• Vehicle efficiency
• Onboard energy storage
• Time to fuel/recharge
• Hydrogen and natural gas availability
Recent ARPA-E Award
U.S. Department of Energy
Advanced Research Projects
Agency – Energy (ARPA-E)
– Methane Opportunities for
Vehicular Energy (MOVE)
• Focuses on reducing CNG vehicle
– 13 Awards totaling $30 million
– CEM awarded $4 million for natural gas
compressor development
Natural Gas Resources
• Massive increases in the U.S.
natural gas reserves over the
past decade present an
unprecedented opportunity for
advancing the economic,
national, and environmental
security of the nation
• Significant technical and
economic barriers exist that
are limiting widespread
adoption of natural gas
Reference: Funding Opportunity No. DE-FOA-0000672 CFDA Number 81.135
Natural Gas Vehicle Barriers
Fundamentally barriers arise
from natural gas’ low
volumetric energy density
– Less than 1/3 of gasoline
Difficult to store in great
Difficult to compress
Ultimate Barrier is Cost
• Assuming a 5-year payback at $2.00/GGE
• Natural gas systems (storage, compression, etc.) must not
exceed $4200
Reference: Funding Opportunity No. DE-FOA-0000672 CFDA Number 81.135
UT’s Project w/ ARPA-E
Near-term Focus
ARPA-E project success
– Natural Gas Industry and Partners
Transit bus demos
– Onboard fuel cell or on-route rapid charge?
Collaboration with EV-TEC and other university groups
– ARPA-E project website and events
– Publish papers
Long-term Outlook
Develop relationships with new sponsors and partners
– COTA and F1
Further compressor development
– Hydrogen and scalability
Explore fuel conversion technologies
Autonomous Vehicles
Key Challenges
Project cost-share
– Several recent DOE opportunities were unrealized
Private funding sources
– Recent and current projects are supported by
federal or state funds
Vehicle technology is changing and
opportunities for CEM are abundant
These opportunities fit well with CEM’s
expertise and strengths
New partnerships must continue to be
