Shell is to acquire 100% of Sonnen, a manufacturer of smart residential storage systems, following an initial investment in May last year. Started up in Germany, Sonnen now also has locations in the UK, Italy, Australia and the USA.

Sonnen offers digital energy services via its sonnenCommunity platform, including sonnenBatterie, which optimises the use of solar power. It has used new business models for a decentralised energy system. Recently, Sonnen put Germany’s biggest virtual battery into operation, based on a network of home electricity storage systems.
