Closed-loop pumped hydro on the rise
Closed-loop pumped-hydro storage offers more chances to minimize environmental effects on water sources and overcomes the problem of finding suitable sites. According to an Australian research team, closed-loop systems could prevail on open-loop systems in the future and this trend is confirmed by another group of scientists from the United States.
Storing hydrogen with silicon-carbide nanotubes
Storing hydrogen in carbon nanotubes and other nanostructures is still far from reaching commercial maturity. A Japanese research team, however, has developed a new simulation technology that may help better estimate the energy needed to favor the ideal interaction between hydrogen and its storage material.
Australia’s biggest battery cleared for testing following fire
Energization testing is set to resume this week for Neoen’s 300 MW/450 MWh Victorian Big Battery, following a fire that caught global attention and destroyed two of its Megapacks on July 30.
Renewables vs. Nuclear: 256-0
The latest World Nuclear Industry Status Report shows that the world’s operational nuclear capacity grew by just 400 MW in 2020, with generation falling by 4%. By contrast, renewables grew by 256 GW and clean energy production rose by 13%. “Nuclear power is irrelevant in today’s electricity capacity market,” the report’s main author, Mycle Schneider, told pv magazine.
Indian hydropower producer to deploy 1 GW of PV
SJVN, a state-owned hydropower producer in India, has landed one-fifth of 5 GW of grid-connected PV capacity in a recent tender.
Australian regulator takes Tesla big battery to court
The Australian Energy Regulator has filed a lawsuit against the Hornsdale Power Reserve, which is owned and operated by French renewable energy developer Neoen, over claims that it failed to provide the grid security services it was paid to deliver.
Tesla’s storage facility comes online at Mohammed bin Rashid solar park in Dubai
The 1.21 MW/8.61 MWh storage facility is the second battery deployed at the 5 GW solar park. The system allows bi-directional charging.
Residential lithium-ion battery from Belgium
The battery is available in three versions, with storage capacities of 3 kWh, 5 kWh and 7 kWh with all devices featuring a nominal voltage of 51.2 V and a maximum charging voltage of 56.8 V.
Developer calls world’s largest solar+storage project ‘the first of many’ to come
The Australian-Singaporean group behind a proposed 20 GW solar PV farm and 42 GWh battery energy storage project under development in Australia’s remote far north has hinted that other, similar-sized projects are already in the pipeline.
How long do residential storage batteries last?
Multiple factors can affect the lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.
