Pollinator-focused solar parks

Researchers in the US ascertained that the partial shading provided by solar parks creates a microclimate that favors the abundant growth of more varied flowers and pollinators. They also found that partial shading increases bloom abundance by delaying bloom timing, increasing forage for pollinators during the hot and dry late season.

US start-up secures distribution agreement for nickel-hydrogen battery technology

EnerVenue signed its first major distribution agreement with Hong Kong’s Towngas. The deal will pilot the company’s nickel-hydrogen battery technology and serve as an audition for future deals to come.

First Solar claims lowest module degradation rate in the industry

The US cadmium telluride thin-film module maker said its Series 6 CuRe panels are able to retain 92% of its performance at the end of the 30-year warranty. The improved stability of the product was achieved by eliminating copper and placing Group V elements such as antimony or arsenic onto the tellurium crystal sites.

Geospatial approach to evaluation of potential solar sites

A U.S. research group has used high-resolution data to drill down to individual parcels of land, in order to figure out how much space is available for solar at optimal locations and preferred sites.

Solar+storage pushing aside US coal, natural gas, says IEEFA

Technology improvements and price declines have made solar and wind the lowest-cost options in most of the United States, according to the Institute for Energy Economic and Financial Analysis.

Silicon for batteries moves to commercial production

U.S. company Group14 Technologies today announced the launch of a factory capable of producing 120 tons per year of its innovative silicon-carbon-based anode material for lithium-ion batteries. The factory is located at Group14’s headquarters in Woodinville, Washington and is the first of several planned by the company.

Using PET waste bottles to make batteries

Scientists in the U.S. claim to have successfully upcycled PET waste bottles into an electrochemical active-carbon material that functions as a double‐layer supercapacitor substance. They said that this achievement may lay the ground for the production of more sustainable batteries. Devices built with the proposed technique would not store as much energy as lithium-ion batteries but they could charge much faster.
