Program Overview
As society continues to evaluate future alternative fuel vehicles, CEM’s experience in power systems have been applied to help guide ongoing discussions, and development much needed technologies. Many municipalities are actively evaluating alternative fuel options for both transportation and fleet vehicles. To assist, CEM is capable of providing knowledge regarding the technologies under consideration, power system modeling capabilities for comparison of system options, and engineer design and testing skills assisting in prototype development to assist in technology assessment or to bring forward new technologies needed for fuel advancement in the marketplace. Whether it is mass transit or personal transportation, the methods and communications of transportation are rapidly changing within communities, requiring a group like CEM with in-depth knowledge of emerging technology options and the capability of developing innovative new solutions to bring to market.

Two Decades of Hydrogen Research
CEM has been a leader and centerpiece for applied hydrogen power and energy research at the university. Starting with the first permanent hydrogen refueling station and commercial fuel cell vehicle in Texas. This research has led to numerous prototype demonstrations, industry collaborations, and exposed dozens of student to hydrogen technologies.

Hydrogen Fuel Cell Vehicle Developments
CEM’s expertise in modeling and understanding power systems is at the core of our research and development of hydrogen fuel cell vehicles and powertrains. We have prototyped and demonstrated fuel cell vehicles and powertrains across a wide class of vehicles, including small utility vehicles, medium-duty parcel delivery vans, and heavy-duty transit buses and trucks.

Hydrogen Energy Systems and the Proto-hub
CEM’s latest hydrogen R&D facility, the ProtoH2ub, leverages an award from the Department of Energy’s Hydrogen and Fuel Cell Technologies Office. The ProtoH2ub is a first-of-its-kind hydrogen ecosystem with thermal and electrolytic hydrogen production, 350 bar and 700 bar vehicle fueling, and a fuel cell hydrogen power system. It represents a unique capability for applied hydrogen research, education, and training.
CEM Approach
CEM’s history in power system design and analysis, along with prototype development, provide an ideal foundation for this program. CEM leverages enterprise software tools to conduct system design, analysis and validation. CEM’s analysis tools allow consideration of an array of parameters effecting system performance. These tools also allow for a seamless transition into prototype development and testing. To date, CEM has participated in multiple fleet vehicle assessments in partnership with city transportation providers, environmental agencies, government officials, and commercial companies. In addition, the Center has participated in technology development projects funded from the DOD, DOT, and ARPA-E.
