"The Beijing (China) Bus Company will soon begin a large-scale test of heavy-duty hydraulic hybrid systems, deploying the technology on 50 buses that it will use in daily operations. Successful results could spur broader use of the hybrid systems within a year.
Instead of the battery pack and electric generator/motor used in electric hybrids, a hybrid hydraulic system uses an accumulator (which stores energy as highly compressed nitrogen gas) and one or more hydraulic pump/motors."
