On June 3, 2012, a team of University of Maryland students received the grand prize in the Hydrogen Education Foundation’s 2011-2012 Hydrogen Student Design Contest. The contest, which attracted entries from 28 universities representing 9 different countries, involved designing a combined heat, hydrogen, and power (CHHP) plant for a University campus, using locally available waste resources for primary energy input.
The multidisciplinary team of graduate nd undergraduate students, advised by University of Maryland Energy Research Center (UMERC) associate director, Professor Greg Jackson (Mechanical Engineering), was led by Department of Mechanical Engineering (ENME) graduate student Jennie Moton. Moton, Jackson, and 9 other group leaders of the 28 member team from UMD traveled to the World Hydrogen Energy Conference 2012 in Toronto, Canada to receive the award and present their proposed plant design, “Recommended Design for the University of Maryland Combined Heat, Hydrogen, and Power System”.
This year’s contest theme, to develop a plan for the construction of a plant to be operated using fuels derived from the waste streams of the UMD campus and the local community, fits in well with the campus sustainability initiative to reduce our carbon footprint. The students worked closely with facilities managers, including campus-wide Energy Manager Joan Kowal, and the university’s Recycling Coordinator Bill Guididas to assess the campus energy infrastructure and all of the local waste streams and processing methods.
The plant design includes both an anaerobic digester and a steam + O2-based waste gasification system that produces fuel for use in a Fuel Cell Energy 1.5 MW molten carbonate fuel cell system. The system is designed to deliver a net output of 1.2 MW of power to the campus grid while dramatically reducing shipments of waste from the campus. The system is also specifically designed to produce excess hydrogen that will be stored and used in fuel-cell powered buses, such as those now being developed by companies like Ballard Power Systems. UMERC researchers have been collaborating with Ballard Power Systems in College Park for the past 5 years. In addition to the H2 fuel, the waste-processing plant produces steam from the molten carbonate fuel cell exhaust, which can be integrated into the campus cooling and heating system. The team’s calculations indicate that implementation of the proposed CHHP system could reduce UMD’s carbon emissions by more than 4%, while saving the university over $2 million per year in combined heating, electricity, and hydrogen costs.
In addition to the engineering and environmental analysis aspect of the competition, team members also developed a marketing and education plan for the student population at UMD. The plan includes an End Use Alternative Contest, and will involve multidiscipline teams from UMD’s Gemstone and Honors College programs, in addition to students from the Clark School of Engineering and the Smith School of Business.
