Nu e science fiction: Energia ar putea fi stocată în subteran. Ce au descoperit cercetătorii

Portuguese scientists are exploring compressed air energy storage in underground porous rocks, a concept dating back to the 1970s. This method could enhance renewable energy storage, addressing the surplus energy issue. Researchers suggest using underground rocks as a battery to store excess electricity from renewable sources like wind and solar. The process involves compressing air and storing it in rock formations, which can later be released to generate electricity without combustion. Europe aims to increase its energy storage capacity significantly by 2030, and this technology could help meet that goal by providing long-term storage solutions using abundant natural resources.
