Potassium carbonate
A team of researchers from Eindhoven University of Technology, TNO and its spin-out company Cellcius have invented a 'heat battery' based on salt and water that can potentially make millions of homes in Europe gas-free in the near future [1]. It took 12 years to design and develop a battery that could be transformed into a scalable solution and comes at a critical time when the EU is looking to wean itself off Russian gas dependence following the invasion of Ukraine [2]. The battery contains no toxic chemicals, rare or precious metals, and the salt contained within it is potassium carbonate (CHEBI:131526) which is harmless, cheap and abundantly available [1].
