Abstract：The hybrid power construction machinery and hydrogen engine are the typical and representative new developing and utilization energy engine. The research status，application in the engineering and automotive fields and the key technology of them were summarized. To reduce the power consumption further，the different solution strategies were proposed for the low energy recovery，fuel efficiency of construction machinery and early burning，backfire of hydrogen engine. The developed trends of the hybrid power construction machinery and hydrogen engine were summarized and prospected at last. The study result shows that these measures have good feasibility.
