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.
AusNet shareholders overwhelmingly approve $18 billion sale
Victorian network utility AusNet Services appears certain to be entirely foreign owned after shareholders overwhelmingly approved the sale of the company to a consortium led by Canadian asset management group Brookfield.
Tesla Energy results up, but mixed, for 2021; solar makes nary a sound on quarterly call
On the company’s Q4 earnings call, the world-leading EV manufacturer again prioritised delivering cars over growing low-margin energy storage products, while solar products were barely noted. Both verticals grew though, solar by 68% and storage by 32%.
Zinc-air battery and PV to power apartment complex
A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.
Full solar value chain relief is on the way, says ROTH Capital
Philip Shen, managing director of ROTH Capital Partners, hosted top analysts from PV InfoLink to discuss their outlook on pricing, supply and demand at each step in the solar value chain.
Pulling fertiliser out of thin air with PV
Nitricity has developed an experimental plasma reactor that uses PV electricity to produce competitively priced, environmentally clean, nitrogen fertiliser. Its onsite fertiliser production eliminates emissions from transport, and provides a viable alternative to fossil-based nitrogen fixation methods like the Haber-Bosch process.
Tesla turns to Australian company to secure material for its EVs
Electric vehicle giant Tesla has inked an offtake deal with Australian miner Syrah Resources to supply battery-ready graphite as concerns over raw materials shortages continue.
