County of Hawaiʻi bus fitted with new patented invention for fuel cell.
An invention that enhances the longevity and performance of fuel cells has been awarded a U.S. patent. Researchers from the Hawaiʻi Natural Energy Institute (
HNEI) at the University of Hawaiʻi at Mānoa developed a “smart” system called an Environmental Sensor Array that senses and reacts to changing air quality in real time.
Renewable energy has grown to almost one-fifth of the electricity produced in the U.S.—increasing energy security, conserving natural resources and reducing carbon emissions. Fuel cells produce energy for transportation and other applications by combining hydrogen and oxygen, producing exhaust that is nothing more than water.
