Abstract
A gravitational energy storage system is provided that includes one or more tracks extending from a lower storage yard to an upper storage yard, a plurality of mass cars moveable along the track, a conveyance system comprising at least a first tether, and a first power module associated with the first tether to drive a respective one of the first tethers to move the plurality of mass cars from the lower storage yard to the upper storage yard, and to dispatch energy when the plurality of mass cars are moved from the upper storage yard to the lower storage yard.
Claims20
An energy storage system comprising:
- a track extending from a lower storage yard to an upper storage yard, the track having an inclined area between the lower storage yard and the upper storage yard;
- a plurality of mass cars moveable along the track, each of the plurality of mass cars comprising at least one coupling member;
- a conveyance system comprising at least one tether comprising a plurality of fixtures configured to engage with the at least one coupling member of a respective mass car;
- and
- a power module associated with the at least one tether comprising at least one motor-generator configured to drive a respective ones of the at least one tether to move the plurality of mass cars from the lower storage yard to the upper storage yard along the track, and to dispatch energy when the plurality of mass cars are moved from the upper storage yard to the lower storage yard along the track.
