Giant Underground Pools of Water Are Batteries of the Future
In an energy-efficient future, homes may be heated and cooled by pumping from giant pools of water stored underground. A study published this month in Applied Energy looks at how underground aquifers could help significantly reduce reliance on fossil fuels and help store energy produced by renewables.This Summer’s Hottest UmbrellaThe research deals with a technology known as aquifer thermal energy storage, or ATES. Water is a great way to store thermal energy, and the Earth is an efficientinsulator. ATES is simply the…
