Heat is one of the biggest energy needs and is currently supplied by gas. Heat that is currently still mostly extracted from gas. However, a lot of unused residual heat is discharged in the industrial sector. Cellcius‘ heat battery makes it possible to store this residual heat and then later use it for heating homes and homes, virtually without loss in this storage process and over time. The innovative thermal battery is the solution for loss-free transport of residual heat and works with two simple and safe ingredients: salt and water.
