Today we achieved another industrial milestone: the successful inspection test of our first steel cassettes to be integrated and operated in a commercial energy storage project. Pressure testing the cassettes up to 168 bar and a trial stacking procedure proving our precision engineering under the full auspice of 3rd party inspectors. Working together with our diligent partners Apex Heat Transfer, we have managed to deliver on our project timeline despite the tremendous disruptions caused by the COVID-19 pandemic. Enjoy below video capturing the moment when the EnergyNest steel cassettes were stacked on top of each other – demonstrating the simplicity and space efficiency that can be achieved with Thermal Battery solutions.
