Flow battery advocates say their water-based technology needs a fraction of the metals used in lithium batteries and can store energy longer and without fire risk. But high costs could limit its role ...

Flow batteries can feed energy back to the grid for – much longer than lithium-ion batteries which only last four to six hours. I was of one of the main types of flow battery in the 1980s.

By using modular power flow control technology, NGET can remove bottlenecks and unlock unused capacity on the existing network. NGET has already installed 48 SmartValves across five circuits at three ...

Taking electricity and making it into something that can flow, like water in a pipe, is a bit more involved. In August 1831, British scientist Michael Faraday discovered that when a magnet was passed ...
