Australian researchers reveal new way to split saltwater into hydrogen
Australian scientists have developed a new way to make hydrogen directly from seawater. They have described the technology as a critical step to a truly viable green hydrogen industry.
Manufacturer releases home backup solar battery
RoyPow introduced a new residential lithium-ferro-phosphate battery this week at Intersolar North America in Long Beach, California.
Global solar installations may hit 350.6 GW in 2023, says TrendForce
TrendForce says solar demand could grow by more than 53.4% this year due to lower module prices and delayed projects from 2021 and 2022 that are now going online. China will be the largest market this year with 148.9 GW, followed by the United States with 40.5 GW, India with 17.2 GW, Brazil with 14.2 GW, Germany with 11.8 GW, Spain with 11.4 GW, and Japan with 8 GW.
Iron-chromium flow battery for renewables storage
Researchers in China have successfully prepared cobalt oxide-modified graphite felt as an electrode material for an iron-chromium flow battery. The electrode performance significantly improved due to the effects of cobalt, which in turn boosted the energy efficiency and overall performance of the battery.
PVH to build world’s largest tracker factory
PVH has confirmed that it will build a new manufacturing facility in Valencia, Spain. The factory will raise its global tracker production capacity to 25 GW.
Saltwater flow battery added to solar-on-canal project
The University of California, Merced, has shown that up to 13 GW of solar capacity could be installed over California’s canals, which would require approximately 3 GW of energy storage.
Curtailment is not the enemy
A new report by IEA-PVPS Task 16 looks at the use of “implicit storage” to transform intermittent renewable sources such as solar and wind into firm power generation. It shows that the total cost of the electricity system transformation could be lowered with the optimal use of capacity overbuilding and dynamic curtailment.
Pakistani regulator backtracks on amendments to net-metering tariff
Amid fierce public opposition, Pakistan’s National Electric Power Regulatory Authority (Nepra) has decided not to proceed with proposed amendments to its 2015 net-metering regulations. Nepra originally planned to reduce the tariff paid to net-metered households from PKR 19.32 ($0.072)/kWh to PKR 9/kWh.
Only5mins! – Wind and solar hybridization
Joachim Steenstrup, head of public affairs for Denmark-based Eurowind Energy, speaks to pv magazine about hybrid solar-wind projects, why the hybridization trend makes financial sense, and how PV-wind hybrid installations are the building blocks for the “energy centers” of the future.
UK manufacturer releases new PV testing tool
Seaward’s new PV150 test instrument measures open circuit voltage, short circuit current, earth continuity, insulation resistance, and operating current. It weighs 0.95 kg and comes with a two-year warranty.
