Energy Storage

Following the early success of its solar integrated Gannawarra Energy Storage System, Edify Energy has again opted for Tesla Megapack as its preferred battery energy storage system for its combination of storage projects totalling 150MW/300MWh in the Riverina region of New South Wales.

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-metre facility is being constructed 30 metre below ground and will begin storing green hydrogen next year.

Construction of the Kogan Renewable Hydrogen Demonstration Plant in Queensland’s Western Downs region is expected to start by September, with government-owned CS Energy, the plant’s operator, having finalised the EPC contract with IHI Engineering Australia to construct the project.

New Zealand’s federal government has opened the final funding round in its NZ$14 million (AU$13 million) Māori Housing Renewable Energy Fund, open to small and larger-scale projects.

The rollout of rooftop solar in the remote coastal town of Broome in northern Western Australia is set to get a boost with state-owned regional energy provider Horizon Power installing two centralised community batteries that are expected to unlock more than 1,400kW of solar PV hosting capacity.

Australia’s biggest power producer AGL has secured planning approval for a 500MW/2GWh grid-connected utility scale battery to be developed at the site of its coal-fired Liddell power plant in the New South Wales Hunter Valley.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh (AU$0.18/KWh)

A report published by IRENA hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.

Australian redox flow battery manufacturer Redflow’s push into the United States market has received a major boost with the company announcing it will work with California-based biowaste technology firm Anaergia on the installation of a solar and 5.5-6MWh battery energy storage solution.

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, found a study using an idealised grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology.
