The thermal battery capable of producing solar energy at night

This innovative battery prototype could give a boost to solar energy and establish itself as a competitive alternative to the use of fossil fuels as a source for electricity production.

Technology must be the great ally of renewable energy in the ultimate goal of building a sustainable and environmentally friendly future. In this context, initiatives that are committed to innovation will allow us to make a difference in the face of climate change and open new paths when it comes to finding new ways to produce electricity efficiently and competitively.

A team of researchers from the University of Curtin is developing an innovative thermal battery that can be the key to start the production of electricity at night using solar energy.

The battery consists of a concentrated solar energy system that stores, releases and allows the generation of solar energy continuously. The intention of the researchers is to implement a method that competes with fossil fuels as a source of energy supply in the commercial and industrial field.

Produce energy without dependence on the sun
Battery operation is based on a heat tank composed of high temperature metal hydride and low temperature gas storage to channel hydrogen and carbon dioxide. The result is a prototype thermal battery with the capacity to produce energy without dependence on continuous exposure to sunlight.

During the nights, and at times when the sky remains cloudy, hydrogen and carbon dioxide are released and absorbed by the metal at high temperature. This process culminates in the formation of a metal hydride / metal carbonate that produces the energy source of electricity.

It will revolutionize the panorama
“The development of a cost-effective energy storage system with thermal batteries will revolutionize the landscape of renewable energy production worldwide, and allow them to truly compete with fossil fuels,” said Professor Chris Moran in the statement issued by the Curtin University.

The really revolutionary aspect is that thermal batteries have the ability to concentrate and retain heat and use it when the sun does not shine to drive a motor that continues to produce energy.

The main difference from traditional lithium batteries is that they are only able to use previously stored energy, but not continue producing without direct exposure to sunlight.
