NEWARK, Del. — At the University of Delaware, a team of researchers has begun to investigate the use of solar power on the fuel-cell bus fleet as a way to reduce operating costs without increasing greenhouse gas emissions, UDaily reported.

Engineering researchers have used simulations to demonstrate the design, operation, control and economics of incorporating solar power into a hybrid renewable energy system for automotive applications, according to the report.

The program currently includes two 22-foot, 22-seat transit buses equipped with nickel-cadmium batteries to meet the power demand of the buses and hydrogen-fueled proton exchange membrane fuel-cells to maintain the state-of-charge of the batteries, UDaily reported. For the full story, click here.
