The 18-meter long solar cell-clad trailer is said to enable fuel savings of 5-10% in Sweden. Swedish thin-film manufacturer Midsummer is a partner on the project.

Huanghe Hydropower Development has connected a 2.2 GW solar plant to the grid in the desert in China’s remote Qinghai province. The project is backed by 202.8 MW/MWh of storage.

Built in Gangba County, in Xigaze, Tibet, the 40 MW/193 MWh facility was deployed at more than 4,700m above sea level and is functioning as a demonstration project for the ancillary services the technology could offer the Tibetan grid.

International researchers have analysed the potential of sodium-based energy storage and found recent technical advances have arrived faster than those for the lithium-ion batteries which have been studied for three decades. Issues remain, however, before sodium constitutes a complementary option to lithium.

The latest edition of the World Nuclear Industry Status Report indicates the stagnation of the sector continues. Just 2.4 GW of new nuclear generation capacity came online last year, compared to 98 GW of solar. The world’s operational nuclear power capacity had declined by 2.1%, to 362 GW, at the end of June.

A new research paper looks at the membranes used for applications in vanadium redox flow batteries. It outlines various membrane technologies and the obstacles to bringing batteries to mass production.

Brazil now has 12  GW of underperforming hydropower capacity, according to U.S. researchers. Large-scale floating PV is an ideal solution to offset this shortfall, due to its high capacity factor, load correlation, and high potential output during periods of high demand.

Around 4.2 MWh of energy storage capacity will be connected to a solar and diesel micro-grid on Rarotonga, the largest of the islands in the South Pacific nation. Three 40-foot containers with a total power output of 4.8 MVA will be used as a power reserve and for grid support by utility Te Aponga Uira.

Solar curtailment might become a valuable aspect of future PV deployment, particularly if grid operators start focusing on ‘curtailment management’ instead of ‘curtailment prevention.’ Management would include measures such as flexible generation, storage, load flexibility, and regional coordination.

A Chinese research group has developed a PERC cell on a commercial 180-μm-thick monocrystalline silicon wafer with a standard size of 156 × 156 mm2. The cell has an open-circuit voltage (VOC) of 0.677 V, a short short-circuit current (ISC) of 9.63 A, and a fill factor of 80.30%.
