Sonnen has been one of the top competitors with Tesla’s Powerwall in the US domestic battery market. The corporation built its base in Germany, attaching batteries for self-consumption to houses with solar panels. Sonnen now claims 40,000 batteries established in families in Germany, America, and Australia. The corporation’s assets encompass a proprietary software program that optimizes a home’s battery use with solar electricity.

In May of the remaining 12 months, Sonnen deployed a “virtual battery” device in Germany, aggregating residential batteries into one-megawatt blocks. As Sonnen wrote in a press release at the time: “If deviations stand up inside the grid frequency of 50 Hz, the power storage structures can automatically, and in a rely of seconds on, either supply power to the power grid or take power from it—relying on what’s presently required. Until now, it has especially been CO2-in-depth power stations used for this primary balancing energy; Sonnen’s networked residential power garage systems are supporting accelerating the removal of those power stations from the grid in Germany.”

Shell is a quality known as a store of the types of CO2-extensive gas that Sonnen aimed to cast off with its virtual battery. However, Shell has been investing in low-carbon generation in recent years, intending to diversify in advance of a carbon-regulated future. In its acquisition announcement nowadays, Shell said it might increase awareness of “electric car charging solutions and the availability of grid services which might be based on Sonnen’s virtual battery pool.”

Shell purchased an electric vehicle charging startup called Greenlots, and in 2017 it obtained NewMotion, a Dutch agency that operated 30,000 electric vehicle charging stations in Europe.

The subsidiary making those acquisitions and investments for Shell is called Shell New Energies. It was founded in 2016 to enhance the employer’s interests in energy, biofuel, and hydrogen.
