At the forefront of technological innovation, there is a limit to the amount of electricity that can be delivered to the grid from intermittent renewable energy sources.
Renewable energies such as solar and off/onshore wind are now widely affordable. However, production unpredictability and intermittency from reliance on factors such as wind and sunlight mean that renewables have not been able to fully replace fossil fuel generation.
Today, we want to present an innovative solution for this challenge which renewable energies have faced with it for a long period of time, that is, Gravity Storage.
Based on the principles that underpin traditional gravity-based pumped hydro plants, the new solution combines conventional physics fundamentals of potential and kinetic energy with a proprietary, cloud-based software platform to operate a newly developed six-arm crane. The crane operation is fully automated and moves massive concrete bricks that provide the basis for the efficient storage and discharge of electricity.
The system specifications include:
*35-MWh nominal energy capacity and 4-MW peak power; can be modulated as required.
*Millisecond response ramp time with 100% full power achieved in 2.9 seconds, supporting critical Ancillary Services.
*Roundtrip efficiency of ~90%; zero storage degradation over time with no energy loss; >30 year lifetime with unlimited cycles.
