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.

Dragonscale solar tiles installed on Google buildings

Some 90,000 individual solar panels will generate enough electricity to cover around 40% of the electricity used in two buildings for Google.

Plastic for solar panels?

Three companies are swapping out aluminium and glass in favour of plastic to save weight and add flexibility. We look at the pros and cons.

Iron flow battery tech shows promise for mid-duration energy storage

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.

Energy storage appears to be fully charged for exponential growth

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.

Do engineers dream of solar panel efficiency?

A true next generation of solar cell technology is upon us. It is time to contemplate the benefits.

Using machine learning and cheap satellite data to design rooftop solar power

Researchers have built a tool to use cheap satellite imagery – like Google Maps – to automatically create solar designs with a 91% accuracy rate.

Bifacial beats Trump’s tariffs

Federal trade authorities have ruled that bifacial solar modules are no longer subject to the Section 201 ruling, which currently apply a 25% tariff to most solar modules imported to the United States.

California is learning to trust 100% residential solar power

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.

California’s solar power record setting season arrives

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.
