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 […]

Massachusetts Institute of Technology engineers have developed a heat engine with no moving parts that is more efficient than a steam turbine. The researchers say the design could someday enable a fully decarbonized power grid. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… National Renewable Energy Laboratory (NREL) scientists have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the building’s energy use. Their work product, featured in Nature Energy, proposes a new […]

Massachusetts Institute of Technology researchers have created a material for a chemical heat ‘battery’ that could release its energy on demand. The new phase-change material provides a way to store heat in a stable chemical form, then release it later, on demand, using light as a trigger. A good example for its use is that […]

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), […]
