Developing a first of its kind
thermal energy storage
system with US
Department of Energy
(NREL) utilizing our high
purity silica sand for
purification, industrial heat
and electricity arbitrage.
KEY POINTS:
Partnered with the US Department of Energy’s National Renewable Energy Lab (NREL) for development.
Development of thermal purification of Homerun silica sand within the Enduring Energy Storage System
Ready for commercial pilot installation.
Lower CAPEX and operating costs compared to BES.
Longer lifespan, TES can last up to 30 years reducing replacement costs.
Scalable for broad applications from onsite MWh storage to utility GWh long duration storage without geologic/geographical limits.
COMPLETED:
Developed thermal cycle testing plan.
Screened purification methods by thermal and thermochemical processes.
Measured Homerun sand particle size distributions and sand heat capacity.
Developed data from testing for initial Thermal/Acid process flow to purify Homerun’s silica.
IN PROCESS:
Assessment of silica post-storage as value-added feedstocks to renewable materials.
Develop energy storage configuration based on a site and material processing methods.
Develop plant configuration with component size and layout that considers material handling and generate a process flow diagram.
