In a study published recently in Nature Communications scientists at the University of Tokyo announced that they had created a material that could store up heat and then release it on command, with just a little bit of pressure applied. The material is a ceramic, but not the kind you’d use in pottery class. It’s called stripe-type-lambda-trititanium-pentoxide and is made of titanium and oxygen. This new ceramic can store up heat energy over the course of a day, and then release it when needed. One of the big problems with machines, electricity generation, and basically anything with moving parts is that a lot of energy is released as heat, dissipating into the environment with no way to capture what was lost. Think of how a car engine heats up while in use, or a conventional lightbulb. When those items work, they create heat, which is basically wasted energy. With a ceramic that can absorb heat and then release it on command, that energy has the potential to be used instead of wasted. The team hopes that it could help reduce industrial heat waste, become an integral part of renewable energy technologies, like solar panels, and eventually be used in electronics and computers. but don’t expect to see it on shelves anytime soon.
