These planned fuel-cell generators could eventually replace gas- and diesel-burning generators with fewer emissions at worksites, buildings, movie sets, data centers, outdoor concerts and festivals. They could also back up or temporarily replace grid-sourced electricity for residential and small commercial enterprises at times of power disruption. Each HYDROTEC-based power generator has zero-emissions electric power generation output ranging from 60 kilowatts to 600 kilowatts, along with low noise1 and heat signatures2.
