NREL, Homerun, and B&W have recognized the potential of using the novel energy storage technology to upgrade Homerun’s silica sand while providing clean, reliable energy. 

This initiative supports Homerun’s goal of refining its silica sand to serve various industrial sectors.

The project is designed to support an advanced energy solution in long-duration energy storage using particle-based thermal energy storage and overcome market hurdles for using this technology in broad decarbonization applications.

The Parties will analyze the economic benefits of using Homerun’s silica sand for energy storage, including energy arbitrage from energy storage and grid service, processing of the silica sand by using low-cost electricity in energy storage and generating potential income from processed materials after its use for energy storage (e.g., high-purity silica sand for renewable materials).

NREL-led technology development using particle-based thermal energy storage aims to enable a low-cost technology for long-duration thermal energy storage (LDES). 

The ENDURING project led by NREL and collaborated with industry partners has developed key components in the storage system and verified their operation mechanism through laboratory prototype testing and modeling of the component and system performance.
