Thermal Energy Storage

The need for thermal energy storage alongside electrical storage

Full-scale test lab

As a part of our work to develop a commercially viable thermal energy storage system, we made an investment to build out a mechanical test lab that provides all of the heating and cooling needs for our 35,000 sq ft net-zero headquarters 2 (aka HQ2) building driven by several sinks/sources… more

Mid-scale lab test and T-Bank™ demonstrator

Our mid-scale test lab allows us to test thermal energy storage prototypes to evaluate the performance of phase change materials, heat exchangers, and tank designs… more
