Abstract
The present disclosure proposes a system for storing energy. The system includes upper and lower reservoirs, a working fluid, and a conduit arranged to permit flow of the working fluid from the upper reservoir to the lower reservoir under gravity. The conduit has a turbine generator arranged to be driven by the flow of the working fluid to generate energy. A heat transfer device is arranged to transfer heat to and/or from the upper reservoir and/or lower reservoir.
Claims19
A system for storing energy comprising:
- upper and lower reservoirs;
- a working fluid;
- a conduit arranged to permit flow of the working fluid from the upper reservoir to the lower reservoir under gravity,
- the conduit comprising a turbine generator arranged to be driven by the flow of the working fluid to generate energy;
- and
- a heat transfer device arranged to transfer heat to and/or from the upper and/or lower reservoir, wherein the heat transfer device comprises a heat pump, and wherein the heat transfer device comprises one or more pipes extending between the heat pump and the upper and/or lower reservoir;
- and
- a computing arrangement configured to receive data related to the temperature of the upper and/or lower reservoir, wherein the computing arrangement executes a predictive temperature control model to:
- determine a predicted temperature for the upper and/or lower reservoirs, and
- activate the heat transfer device when the predicted temperature falls outside a defined operating range.

A method of storing and generating energy, the method comprising the steps of:
- transferring a working fluid from a lower reservoir to an upper reservoir;
- storing the working fluid in the upper reservoir;
- permitting flow of the working fluid from the upper reservoir to the lower reservoir under gravity through a conduit connecting the upper and lower reservoirs, the conduit comprising a turbine generator arranged to be driven by the flow of the working fluid to generate energy;
- transferring heat to and/or from the upper and/or lower reservoir to maintain the temperature of the upper and/or lower reservoir within a defined operating range;
- and
- executing, by a computing arrangement, a predictive temperature control model, wherein the computing arrangement receives data related to the temperature of the upper and/or lower reservoir, determines a predicted temperature for the upper and/or lower reservoir using the predictive temperature control model, and activates a heat transfer device when the predicted temperature falls outside a defined operating range, wherein the heat transfer device comprises a heat pump, and wherein the heat transfer device comprises one or more pipes extending between the heat pump and the upper and/or lower reservoir.
