This start-up is using thermal energy storage to cool global warming

A huge portion of the peak demand in the energy grid is driven by air conditioning, especially in hot climates. Energy use for cooling buildings has doubled over the past two decades, with warmer temperatures being one of the main drivers, according to the International Energy Agency.

Air conditioners and electric fans account for around a fifth of total energy consumption in buildings. This equates to a tenth of all global electricity consumption. In the next three decades, air conditioning is set to advance to one of the top drivers for global energy demand - not just in hot countries - such as China and India - but also in the rest of the world.

Most of this energy is sucked up by chillers, which cool down the water and pump it through the building to lower temperatures. It’s a highly energy-intensive process, making a big dent in our ability to reduce energy usage and carbon emissions.

The energy-storing capabilities of ice could provide a more efficient, climate-friendly approach to cooling with the help of ice thermal energy storage. Read more
