World’s largest lithium-ion battery is down, again
The Moss Landing Energy Storage Facility Phase II in the United States set off fire alarms that activated a fault water suppression system, triggering a cascading set of events that resulted in roughly 10 battery packs melting down.
Viologen redox flow battery for renewables storage
Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm2, an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm2. The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than US$100/kWh (AU$140).
Water-based electrolyser for green hydrogen production
U.S. company Verdagy has secured a US$25 million (AU$35 million) investment for its new electrolyser technology, which provides hydrogen fuel for heavy industrial applications. The membrane-based technology uses large active area cells, high current densities, and broad operating ranges to deliver hydrogen at scale.
Next-gen concentrated solar power now under development in US
In new studies led by researchers from the National Renewable Energy Laboratory, the US Department of Energy pursues an energy cost goal of US$0.05 per kilowatt-hour.
‘Solar and wind deployment could not now be stopped if we wanted to’
BloombergNEF’s Jenny Chase has surveyed the state of affairs in world solar for clean energy journal Joule and said the technology’s historic ability to surmount obstacles – and persistently confound analysts’ predictions – should offer a reason for hope.
U.S. President provides backing for Brisbane-based EV charging company
Australian electric vehicle charging powerhouse Tritium continues to make inroads in the international market with United States President Joe Biden providing his backing for the company after it announced it will develop a new DC fast-charger manufacturing facility in the southern state of Tennessee.
Grazing animals increase carbon sequestration by up to 80% in PV projects
Temple University researchers have found that managed sheep grazing on an acre of recovering agricultural soil with native plants may sequester 1 ton of carbon per year, which could accumulate for 12 to 15 years before reaching saturation.
Forget batteries, what if surplus renewable energy could be stored as information?
A pair of researchers from the University of California San Diego have proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.
Microgrid project using vanadium redox flow battery
SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.
The panel and the city
U.S. researchers have investigated how rooftop PV systems may affect air and building temperature in urban environments and, conversely, how the urban heat island (UHI) effect may have a negative impact on PV system performance. Their work considered urban air temperature, urban air pollution, the partial shading of the PV system, soiling, building heating and cooling loads, and outdoor shade.
