Cat's hydraulic hybrid technology allows the new 336EH to get 25-percent greater fuel efficiency than the standard 336E and 50-percent greater fuel efficiency over the Cat 336D. Liebherr's R 9XX 40-ton prototype electric hybrid excavator features an electric hybrid driveline and is powered mostly by a standard diesel engine, though it also uses an electric storage device known as supercaps and a hydraulic pressure accumulator. The hybrid system on the R 9XX can supply short-term peak power at up to twice the rated output of the diesel engine. Want more?
