The National Solar Thermal Testing Facility (NSTTF) excels in the research and development of heat transfer fluids and thermal energy storage systems.

Thermal energy storage has a number of benefits, including high-energy density, low costs, a readily available media storage, the ability to deliver heat and electricity, and the ability to be charged with heat and electricity. But challenges to TES deployment remain: investors are hesitant due to limited build out, industry is comfortable with the well-established Li-ion battery market, and TES benefits are not widely understood.

With decades of experience in molten-salt development and solid media R&D, the facility has established itself as a leader in this field. NSTTF boasts multiple testing facilities dedicated to advancing these technologies, ensuring efficient and reliable thermal energy storage solutions. This extensive expertise and infrastructure support the ongoing innovation and optimization of solar thermal systems, contributing to the broader adoption of sustainable energy technologies.
