Thermopylon LLC is structured around development of cost effective and compact thermal energy storage systems that enable passive, non-powered, repeatable storage and release of heat. It is suggested that this could offer significant tactical and practical advantages for soldiers mission execution and success in a deployed setting of cold climates. Sorbent systems can store heat indefinitely - however, current sorbent-based technologies require storage tanks and complex controls that are costly and difficult to operate and maintain. Thermopylon is addressing development of an innovative smart thermal battery technology whereby a sorbent material is paired with smart materials that can be engineered such that the sorbent stores heat using adsorption-desorption principles. The stored heat can thus be released in a passive, time-controlled way when encountering an external thermal stimulus
