UK generator and temperature-control rental company Aggreko has entered an agreement to buy loss-making German energy storage pioneer Younicos for £40m ($52m) to strengthen its expansion in global energy markets.

“As energy markets continue to decarbonise, decentralise and become more digital, the integration and control of multiple energy sources, including thermal and renewable, will be essential to ensure the provision of reliable power,” Aggreko chief executive Chris Weston says.
