Lumenion / Vattenfall Energy Solutions / Gewobag

Energy start-up Lumenion, Vattenfall Energy Solutions and Berlin-based housing company Gewobag have kicked off a steel storage pilot project in Germany’s capital to store excess regional wind and solar power, the companies announced in a press release. Excess power will be stored in steel plates for less than 2 cents per kilowatt hour as heat (up to 650° Celsius), which can be used directly, or converted back into electricity when needed.
