Innovative battery technologies, such as molten salt and human sweat, are being developed to store renewable energy more sustainably.

Molten salt and human sweat: the weird batteries that could store renewable #energy From Nevada to Manchester, developers are trialling innovative solutions to clean energy’s biggest challenge https://www.theguardian.com/environment/2026/jul/19/molten-salt-human-sweat-weird-batteries-store-renewable-energy #142holdheap #RenewableEnergy #battery #environment

#SolarpunkSunday #renewables #FossilFuels #CriticalMinerals #solarpunk #energy #GreenEnergy Clean, renewable batteries without lithium, cobalt and nickel. Liquid air, molten salt, sand and sweat. Unlike lithium which has a limited number of discharge cycles, these newer (and cleaner) batteries can potentially work indefinitely. https://www.theguardian.com/environment/2026/jul/19/molten-salt-human-sweat-weird-batteries-store-renewable-energy
