June 24 (Renewables Now) - A subsidiary of Japan's Mitsubishi Heavy Industries Ltd (TYO:7011) has developed a hybrid power supply system that combines solar generation and energy storage with backup from diesel or gas engines.
More specifically, Mitsubishi Heavy Industries Engine & Turbocharger Ltd has installed a so-called Triple Hybrid Power Station demonstration facility at the plant where the firm’s head office is located.
The facility includes a 300-kW solar array, a 500-kW/0.5-hour storage battery, a 500-kW gas engine generator, auxiliary equipment and a control system. In addition, a variable load resistor was installed to allow separation of the facility from the power system line in order to conduct various off-grid tests.
Mitsubishi Heavy says that this offering’s main advantage is the ability to stabilise the volatile output of renewable energy. The firm has decided to name the power generating system EBLOX and the control system COORDY.
