Institutions in Hamburg are proposing to build a large underground thermal heat storage system that could supply roughly a quarter of the city’s heating needs with waste heat from industrial and power plants. If successful, it would make Vattenfall’s plans to realise a CO2-neutral district heating network superfluous. It could also serve as an example for other cities.
Developed by German designers – Andreas Meinhardt and Daniel Abendroth – Hagent is a sort of mobile space heater. Only, instead of plugging into the wall […]
Concentrating solar thermal power has promised big additions to renewable energy production with the additional benefit of energy storage. But with significant water consumption in desert locations, is the energy storage benefit of concentrating solar enough to compete with the dramatically falling cost of solar PV?
We may be about to see a radically new technology in thermal energy storage. Researchers at MIT have been been working on ways to store the sun’s energy in chemical bonds. These developments in this “heat battery” or a “solar fuel,” are due to the addition of carbon nano technology.
