Pământul ar putea deveni o „baterie” uriașă: energie stocată la mii de metri adâncime

Researchers in Portugal are exploring the use of porous rocks underground as natural energy storage systems, utilizing surplus electricity from renewable sources. This innovative method involves compressing air and storing it in rock formations, which can later be released to generate electricity when needed. The study indicates that this technology could potentially store significant amounts of energy, comparable to the consumption of medium-sized cities. The approach offers advantages over traditional lithium-ion batteries, including rapid response capabilities for restoring power after outages. As Europe aims to expand its energy storage capacity, this solution could play a crucial role in enhancing grid stability and reducing reliance on fossil fuels.
