AGL has committed to another big battery project as it seeks to add at least 850MW of new large-scale energy storage to its portfolio by 2024, confirming it will begin construction of a 50MW/50MWh battery at Broken Hill which will improve energy security in regional New South Wales.

Developed by researchers in Spain, the battery uses renewable electricity to melt low-cost metals such as silicon or ferrosilicon alloys to produce and store latent heat, which is in turn used by a thermophovoltaic generator to produce power. According to its creators, the device may store electricity at a cost of €10 per kilowatt-hour (AU$14.6/kWh) for a 10MWh system.

The extensive power outages experienced in Western Australia last Christmas were a result of extreme weather rather than human failure, an independent review has found. The report’s author, AEMC’s Michelle Shepherd, notes such instances will likely become increasingly frequent with climate change.

Nextracker has today launched its new terrain-following, single-axis tracker built specifically for projects on sloped, uneven, and challenging sites. Nextracker believes its new NX Horizon-XTR line will be market-shaping, especially in countries like Australia where opposition to land disturbances of utility-scale solar is growing.

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.

Pure Hydrogen has entered into a partnership with Australia’s largest privately-owned waste management company, JJ Waste & Recycling, to build what it claims will be the country’s first ever hydrogen fuelled garbage truck.

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.

Elsewhere, the Danish government announced a plan to deploy up to 6 GW of electrolyser capacity by 2030 and Germany and Norway agreed to conduct a feasibility study on large-scale hydrogen transport, including via pipeline.
