What are water-based thermal batteries?

Water-based thermal batteries Simply put, these batteries utilise excess renewable energy to heat or cool water to be used for other purposes, sometimes at different times. A good example of a 'water battery' is the 4.5 megalitre battery in use at the University of Sunshine Coast (see case study).

Are batteries more profitable than water heaters?

The results of the study show that batteries are more profitable, since water heaters can store energy for only a couple of hours. For this reason, batteries can provide more revenue to homeowners who are selling their energy back into the grid—yielding an annual operating profit that is almost twice as high as that of the water heater.

What is an example of a 'water battery'?

A good example of a 'water battery' is the 4.5 megalitre battery in use at the University of Sunshine Coast (see case study). An artist's impression of the 'water battery' at the University of the Sunshine Coast, QLD. Image: Veolia Aluminium-based thermal batteries

How do thermal batteries work?

To be able to do so, thermal batteries are made of materials with a very specific criteria. The material should be able to quickly store heat energy, usually by the concept of phase change. Usually, this phase change is triggered when energy (commonly electricity) is available.

Should water heaters be able to store energy at night?

“Thus, having the ability to store that energy midday and use it later during the evening when solar output falls would be of great value,” he says. The results of the study show that batteries are more profitable, since water heaters can store energy for only a couple of hours.
