Dragon scale solar tiles installed on Google buildings in Silicon Valley
Some 90,000 individual solar panels will generate enough electricity to cover around 40% of the electricity used in two buildings for Google.
The Hydrogen Stream: Saudi Arabia bets on blue hydrogen, Denmark wants to improve green alkaline electrolysis
Elsewhere, Snam and Toyota are pushing for more hydrogen-based mobility in Italy, and Woodside Petroleum wants to establish an export-oriented hydrogen and ammonia production facility in Australia.
Converting coal mines into gravity-based renewable energy storage facilities
U.K.-based Gravitricity is planning to deploy its gravity-based energy storage solution at a decommissioned coal mine in Czechia. The project is part of a plan to commence a full-scale, 4-8 MW prototype scheme in disused mines next year.
Retractable PV awning for recreational vehicles
The 1.2 kW solar awning can be retracted automatically in the event of adverse weather conditions. The patented technology, developed by Xponent Power, may enable a wide range of additional applications such as for use by the military, for emergency relief, and residential power.

Jindal India Solar Energy, Shirdi Sai Electricals, Reliance New Energy Solar, and Adani Infrastructure will each have half of their planned 4 GW annual production of polysilicon-to-module output subsidized by public funds.
Longi achieves 25.82% efficiency for heterojunction solar cell
The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.
Solar panels blasted with sound to better understand microcracking
Researchers at NREL and EPRI focused heavy bass sounds on solar panels to simulate the effects of wind-caused deflection.
Plastic for solar panels?
Three companies are swapping out aluminum and glass in favor of plastic to save weight and add flexibility. We look at the pros and cons.
Microgrid-forming PV microinverter from Enphase
The 97%-efficient device is said to be the most powerful PV microinverter developed by the company to date and is capable of forming a microgrid during a power outage. The U.S. manufacturer expects to ship the first products in December.
Morocco + green hydrogen could be at heart of sustainable shipping revolution
With green hydrogen needed to produce the ‘e-ammonia’ required for carbon-free vessels, new clean power generation capacity and potential solar power hotspots near international shipping lanes will be crucial.
