18. Solenco Power Nv

The Solenco Powerbox is an energy storage system based on hydrogen tech. It is charged by electrical power from a renewable source (typically solar PV) and returns both heat and electrical power. It is the missing link between residential needs and the given solar system. It allows to store energy when available and use when needed. It provides a one-stop solution for both heat and power needs and it eliminates the need for a grid connection. Unlike battery systems it can store for hours to months without degeneration/degradation as it uses compressed gas. This allows energy transfer from one season to another.The basic form of storage, hydrogen, can be shared between houses as well or be used as zero emission fuel in hydrogen powered cars. The system is designed to be intelligent. It will monitor all energy flows in the house. FiWare will allow for sharing of this information through the cloud.This creates a bigger user behavior data base and production data can be used for macro optimisation. It is also an important step towards the “Energy Cloud” concept.
