London (CNN Business)Royal Dutch Shell is making a bet on home battery storage as it tries to boost its sustainable energy business.
The oil giant announced Friday that it has purchased Sonnen, a German startup that makes residential battery systems that store energy generated from solar panels.
The move puts Shell in direct competition with companies such as Samsung (SSNLF), LG (LPL) and Tesla (TSLA), which makes a home battery system called the Powerwall.
