Australia-based Lavo has launched the world’s first hydrogen-powered commercial energy storage system. The battery is about the size of a large refrigerator. It is located outside the house and can be connected to a solar inverter and tap water through a purification device. The electrolyzer then uses the collected electrical energy to convert water into hydrogen and oxygen-the system stores enough energy to allow a home to live for two days on average at a time. It provides Wi-Fi, which is an application for monitoring and customization, which can be used continuously for about 30 years. Click here for more details about Lavo Hydrogen Energy Storage System.
