A team of young researchers from Finland have successfully installed the world’s first fully functioning sand battery that has the ability to store green power for several months.
The researchers highlighted that the newly invented battery could resolve the major issue of a year-round supply of green energy. Most energy storage batteries are expensive and are made up of lithium that has a significant carbon footprint and can only manage to store a limited amount of power.
The sand battery uses low-grade sand which gets charged up and electricity generated from renewable sources such as solar or wind and gets stored as heat. These batteries can store the heat at around 500 degrees celsius which can be used in the winter season to warm homes. These sand grains can resolve the storage problem and provide a cost-effective and eco-friendly mode of storing power which can be used when needed.
