Japan’s latest procurement exercise was open to PV projects above 250 kW in size. The ceiling price was set at JPY 10 ($0.074)/kWh.

A research team has used a molecule known as 2,6-dihydroxy-anthraquinone (DHAQ) to improve the durability of organic aqueous redox flow batteries. They claim the molecule enables a net lifetime that is 17 times longer than past research has shown.

European researchers have developed an open-source online tool that can identify areas where renewable energy and synthetic fuels can be cost-effectively produced, where hydrogen hubs could be built, and where grid expansion is needed. It can be used in different sectors across 35 countries.

Over Easy Solar AS has developed a rooftop PV system with two generation peaks – one in the morning at 11 am, and one in the evening at 7 pm. It has been deployed on a school building.

The futuristic Neom City will be powered exclusively by renewable energy, but a co-optimization approach with the water sector will be crucial for desalination and sustainable water supplies. Saudi scientists have assessed different system configurations and determined that solar-plus-storage would deliver the lowest levelized cost of energy.

The Dubai Electricity and Water Authority says its novel redox flow battery stack offers better electrolyte distribution, which could result in higher power densities and lower manufacturing costs.

A Chinese-US research group has designed a proton exchange membrane fuel cell with a hybrid electrocatalyst. The scientists said the device shows remarkable stability and low performance losses.

Scientists in Iraq have applied an amorphous carbon nitride (CNx) thin film as an anti-reflective layer in commercial crystalline silicon solar cells. They claim they were able to improve their efficiency from 5.52 to 13.05%.

Researchers in China have developed a four-junction tandem perovskite/CIGS cell. They claim it is the most efficient device of its kind with an n-i-p structure thus far. They used a novel surface passivation strategy to improve the perovskite cell efficiency and fill factor.

TotalEnergies and Libya’s national utility plan to build a massive solar park in the Sadada region, 280 kilometers southeast of Tripoli.
