A wind turbine may be fitted with the facility store electricity indirectly using one or more thermal stores. The power-conversion machinery is installed within the wind turbine nacelle which rotates to point the turbine into the wind. The thermal storage is realised in the fixed frame - i.e. it does not rotate with the nacelle. The connection between the fixed frame and the rotatable frame is via one or more rotary heat exchangers. While the energy storage is charging, heat passes through the hot heat exchanger to a hot store or coldness passes through the cold heat exchanger to a cold store or both. During discharging, the opposite flows occur. Each rotary heat exchanger has a shell-and-tube configuration. The tube bundle rotates with the nacelle. The shell comprises one set of surfaces that does not rotate and one that does rotate.
