Karlsruher Institut für Technologie (KIT) researchers have now found that low-temperature aquifer thermal energy storage is of great potential in Germany. This potential is expected to grow in future due to climate change. Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground […]

Swiss Empa scientists and their colleagues have spent four years studying the potential of sodium hydroxide (NaOH) to store heat from the warmth of summer into the cold of winter. The theory behind this kind of heat storage is fairly straightforward: if you pour water into a beaker containing solid or concentrated sodium hydroxide (NaOH), […]
