The challenges associated with the modern power grid are identifed in Grid, this in turn is responsible for frequency instability challenges experienced in the Finally, the challenges to the flywheel technology and future work are presented.Īs the world strives toward meeting the Paris agreement target of zero carbon emis�sion by 2050, more renewable energy generators are now being integrated into the The results show that the flywheel-based ERS is competitive with the electrical and hydraulic competitors for HEs. Meanwhile, the drawbacks of flywheels are discussed in detail, indicating that the drawbacks can be offset by other advantages.

The comparison shows that flywheels display many advantages over other energy storage devices. Then, the paper compares corresponding energy storage devices in these ERSs from many aspects.

In light of this, the differences between HEs and automobiles are discussed to highlight the potential of flywheel-based ERSs in HEs. Flywheel-based ERS is not widely used in HEs but has achieved widespread concern in the automotive field. This paper first reviews various hybrid HEs architectures with electrical, hydraulic, or flywheel-based energy recovery systems (ERSs). Hybridization is an effective method to reduce fuel consumption and emissions of toxic pollutants generated by hydraulic excavators (HEs).
