Energy recovery and storage

The technology enables surplus kinetic energy to be converted into electricity and stored temporarily for later use as needed. Operating and investment costs are reduced, as are CO2 emissions. Energy recovery is available as an option on all KASTO storage products and can also be retrofitted to systems already in use.

The electric circuits for the drives of the operating gantry crane are connected through a DC link. Surplus kinetic energy, such as that produced during braking of the crane or lowering of the lifting gear, is converted into electricity and fed back into the grid. The energy can then be used for other purposes, either within the storage facility or by other users. The company says consumption of electric power can be reduced by as much as 40% compared to conventional drive systems. For further efficiency, KASTO optionally equips its storage systems with an integrated energy storage unit.
