Title: Hybrid Solar PV - Hydrogen Microgrids for Remote Locations
Abstract: 
Remote solar PV microgrid and nanogrids utilizing hybrid electric energy storage and hydrogen energy storage systems can provide solutions for off-grid electric power. Options for system integration includes PEM fuel cells and/or compression ignition internal combustion gensets. These integrated systems are known as Power-to-Hydrogen-to-Power (P2H2P) systems. Numerous studies have evaluated optimal system performance and sensitivity analyses using HOMER Pro software. Possible feasible combinations will be discussed, based on the given constraints and inputs, and based on their capital expenditures, operating expenditures, net present cost and cost of energy.
Biography: 
Dr. John W. Sheffield is a Professor of Engineering Technology at Purdue University in West Lafayette, Indiana, U.S.A. His professional career in hydrogen energy technologies began in 1976 when he was working for Pratt and Whitney Aircraft in West Palm Beach, Florida developing high-power, continuous wave, hydrogen-fluoride and deuterium-fluoride chemical lasers. Later, Dr. Sheffield served as one of the founding associate directors at the United Nations Industrial Development Organization - International Centre for Hydrogen Energy Technologies (UNIDO-ICHET) in Istanbul, Turkey.

Dr. Sheffield received his Bachelor of Engineering Science degree from the University of Texas at Austin, and his Master of Engineering Mechanics and his Ph.D. in Engineering Science & Mechanics degrees from North Carolina State University.

For more than 43 years, Dr. Sheffield has served as an editor of the International Journal of Hydrogen Energy, the official journal of the International Association for Hydrogen Energy. Prior to be elected in 2019 as the President, Dr. Sheffield served as the Executive Vice President of the International Association for Hydrogen Energy.
