Circular solar energy storing and releasing system established - green technology science news

Scientists have developed a system that can store solar energy for later use. Importantly, this system is circular, completely free of emissions, and does not damage the molecules that store the energy. This molecule is made from carbon, hydrogen and nitrogen, and changes into an energy-rich isomer when hit by sunlight. Energy can be released with the aid of a catalyst that acts as a filter through which liquid flows, and creates a reaction which warms the liquid by 63 centigrades. The molecule then changes back to its energy-free form. Applications are endless, for instance storing sun energy in the summer, and releasing it in the winter for domestic heating. The developers expect that the new technology could be in commercial use within ten years.
