21st Century Stable Thermal Energy Storage @cleantechnica

21st Century Stable Thermal Energy Storage @cleantechnica

One of the problems we have with solar energy is that it has the most potential in many remote, dry areas. Power must be concentrated and transmitted to population centers. Expensive and less-efficient energy storage is not a preferred option though a necessary component. Photo chemical storage has potential for all of these issues. Passive solar homes can be self-sufficient in heating and cooling. But in crowded urban environments space and solar access are not always an option. Photo chemical storage can address these problems. Solar thermal panels are sized for about 80% of demand. But this risks overheating them in the summer and having insufficient capacity in the winter. Such systems typically use a hot water tank as a thermal mass. A system which replaced the hot water tank with chemical batteries could be shut down while you were away but give heat and hot water wh...
