Energy Storage

Australian renewables company Wave Swell Energy says the time has come for wave power to sit alongside wind, solar and energy storage as part of a modern energy mix after a 12-month trial of its technology in the seas of Bass Strait produced an average rate of conversion from ocean energy to electricity of up to 50%.

Construction has commenced on what will be Western Australia’s biggest battery energy storage system with the first of the battery units installed for the 100 MW/200 MWh Kwinana Big Battery being built at the site of the decommissioned Kwinana Power Station near Perth.

Fourth-generation Victorian dairy farmers this week commissioned their 250kW rooftop solar system coupled with 520 kWh of battery storage from Australian company Energy Renaissance. The couple are forecast to save at least $70,000 annually with the system, cutting their grid reliance by 95% and hopefully inspiring neighbouring farms.

New South Wales is a step closer to adding another big battery to its network with Greenspot securing planning approval from state government authorities for a massive 500 MW/1,000 MWh grid-connected battery to be developed at the site of the defunct coal-fired Wallerawang Power Station near Lithgow.

Mitsubishi Power Americas and Magnum Development are set to begin construction on a 300 GWh underground storage facility in the US state of Utah. It will consist of two caverns with capacities of 150 GWh, to store hydrogen generated by an adjacent 840 MW hydrogen-capable gas turbine combined cycle power plant.

New South Wales has given the green light for another large-scale solar PV and battery project with German-owned renewable energy developer Wirsol Energy announcing it has secured amended development approval for a 445 MW solar and energy storage hybrid power plant in the state’s central west.

Israeli researchers have developed a device that combines a reversible Si anode with halide cathodes and uses hybrid electrolytes to enable cell recharging. In the proposed system configuration, silicon is dissolved during the battery discharge process, and upon charging, elemental silicon is deposited.

French company Neoen has seen its storage revenue “more than tripled” as a result of its recently commissioned Victorian Big Battery coupled with Australia’s energy crisis. In other news, the company signed a 10 year power offtake agreement with Flow Power for its “flagship” Goyder Renewables Zone project in South Australia.

Chinese manufacturer Bslbatt has unveiled an upgraded version of its residential battery. The device has a storage capacity ranging from 5.12 to 12.8 kWh and is reportedly able to provide steady operation for up to 6,000 charge cycles.

Wood Mackenzie places Australia fourth on its list of the globe’s top 10 storage markets, coming in just behind Germany, with the US and China unsurprisingly topping the list. The analyst expects the world’s cumulative storage deployments to reach 500 GW by 2031, according to its Global Energy Storage Outlook released today.
