Solar assets are underperforming expectations by 8%, what is the root cause?
The Renewable Energy Test Center (RETC) raised the issue of ultraviolet-induced degradation of the trending technology in its PV Module Index 2022.
All photovoltaic-thermal system designs at a glance
An international research team has presented all possible system designs and applications for photovoltaic-thermal (PVT) technology. Their review includes conventional PV-T collectors, air-based systems, liquid-based installations, water-based collectors, refrigerant-based systems, heat-pipe-based technologies, dual air-water systems, building-integrated PVT arrays, and concentrated PVT collectors.
US lithium giant doubles down on Australian production plans
Battery chemicals giant Albemarle will invest up to $2.25 billion (USD 1.5 billion) as part of plans to double its lithium hydroxide output in Australia to a volume that it estimates could power almost 2.5 million electric vehicles a year.
Why green ammonia may not be that green
Ammonia has been in the news because of its suitability as a hydrogen carrier and fuel, in addition to being a vital ingredient in fertiliser. Existing distribution networks and the ease of turning ammonia gas into a liquid make ammonia a cost-effective way to transport renewable energy.
Snowy 2.0 pumped hydro project faces another two-year delay
The beleaguered Snowy 2.0 pumped hydro project has been hit with fresh construction delays and added cost blowouts with concerns the multi-billion-dollar project may now not reach full commercial operation until late 2029.
Alinta pushes ahead with WA solar and battery project
Independent power producer Alinta Energy expects work on a 45 MW solar farm and 35 MW/35 MWh battery energy storage system planned for Western Australia’s Pilbara region will commence inside two months following the appointment of contractors to construct and connect the hybrid project.
Failure to cut energy consumption stymies Australia’s net zero progress, ABS statistics show
Data from the Australian Bureau of Statistics has shown that while renewable generation in Australia has increased significantly year on year, the country’s progress towards net zero is stymied by the failure to reduce consumption.
Predictability of regions’ renewable resources has a material impact on project profits, study finds
While many forecasting tools have been developed to improve forecasts of renewable generation, their accuracy is limited by the inherent predictability of the data used – that is, how predictable the renewable resource is in different regions and times of the year. University of Adelaide researcher Sahand Karimi explains why predictability matters and how considering it can save consumers and investors millions of dollars.
Adaptive control of V2Gs incorporating EV owner expectations
Australian researchers have developed a novel adaptive decentralised control strategy for electric vehicle (EV) integration, incorporating both microgrid and EV-side conditions into the primary frequency control. They have proposed new indices to evaluate the charge and discharge capabilities of EV batteries, as well as the satisfaction levels of EV owners.
NSW tender supports $2.5 billion solar and storage projects
The successful projects from the first tender conducted under the New South Wales government’s Electricity Infrastructure Roadmap have been announced with two large solar farms, a wind farm and an eight-hour battery energy storage system to be built as the state looks to manage the exit of coal-fired power generation from the grid.
