Tesla to supply Megapacks for 150MW/350MWh Riverina big battery
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.
Rock cavern for green hydrogen storage takes shape in Sweden
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.
Australia’s first hydrogen-fuelled garbage trucks to hit Queensland streets this 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.
Work on Queensland’s ‘truly green’ government-owned hydrogen plant to start in six months
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 opens $9 million in funding for renewable projects for Māori housing
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.
Hydrogen-powered trains for the German network
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.
Storing renewable electricity with supercritical CO2 heat pump
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)
SunDrive sets 26.07% efficiency record for HJT cell in mass production setting
Australian solar technology startup SunDrive has announced “a breakthrough” in mass production compatible heterojunction technology after recording an efficiency result of 26.07% with a silver-free, commercial-size silicon solar PV cell.
Concentrating solar power with heat storage could compete with batteries
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.
Solar PV with a 50-year lifetime
The US Department of Energy’s durable materials consortium is a multi-laboratory unit that stress-tests solar modules for durability. It seeks to extend the useful life of PV.
