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.
Some 90,000 individual solar panels will generate enough electricity to cover around 40% of the electricity used in two buildings for Google.
The ESS battery systems have a prescribed design life of 25 years, but the battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance.
Lithium-based energy storage volumes in the U.S. are expected to grow by multiple orders of magnitude in the coming years, with a 1000% capacity increase by 2023.
Researchers have built a tool to use cheap satellite imagery – like Google Maps – to automatically create solar designs with a 91% accuracy rate.
California utility PG&E has tested levels of residential solar power up to 100% penetration, and how to mitigate the effects of voltage and thermal overload via smart inverters and traditional transformer and circuit upgrades — with smart inverters shown to allow for up to 100% penetration at cost-effective pricing.
The state grid operator reported breaking 11 GW of instantaneous power from large scale solar on Saturday at 1.50pm. Just 20 minutes earlier, the CAISO grid was exporting a record 1.5 GW of electricity, and last Wednesday it hit 93% clean electricity for a moment.
