New technique stores summer heat until it’s needed in winter

Making the move away from using fossil fuels for heating is a necessary part of creating a sustainable future, but it’s often a difficult ask for many people when turning up a thermostat on a gas or electric heater provides instant, trouble-free warmth. If people are to be convinced to switch to more renewable sources, it makes sense that there need to be easy-to-use systems available to encourage them to do so. A group of Swiss researchers claim to have come up with a process that stores heat captured during summer for easy, flick-of-a-switch use in winter, with the added benefit that the captured energy can be physically transported anywhere it may be needed.

Though still in the prototype stage, EMPA is currently looking for commercial partners to assist in creating a compact version of the system for household domestic use.
