Utility Scale 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.

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.

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.

Federal Labor has promised to allocate $22 million to help establish the Lansdown Eco-Industrial Precinct being developed in northern Queensland if it wins the election in May.

A multibillion-dollar solar, battery storage, wind and potentially green hydrogen project in Victoria’s Gippsland region is moving forward after getting backing from superfund Hostplus. Originally proposed by Solis Renewable Energy, the project is now owned by Octopus Australia as part of its joint venture with CFEC.

The International Renewable Energy Agency has outlined a series of technical considerations for green hydrogen tracking systems. According to the document, a degree of flexibility should be taken into account in the short term to ensure that the nascent green hydrogen market can develop.
