Portuguese Scientists Explore Using Rocks to Store Clean Energy
Portuguese researchers are working on a renewable energy storage solution that uses rock as a storage medium for excess green energy. Their research builds on efforts by German scientists who experimented with using salt caverns to store energy in the 1970s. As fantastical as the idea may sound, the concept of storing energy underground is based on real science and could go a long way towards addressing the intermittency issues that hamper green energy adoption. Fossil fuel-fired power plants still have one major advantage over renewable energy plants; their primary resource isn’t reliant on time and weather conditions. Sure, fossil…
