Residential battery inventories soaring in Europe, says S&P Global
European warehouses are reporting very high inventory levels for residential energy storage systems, with aggressive prices expected, as distributors need to start clearing their stocks, according to S&P Global.
Solar power generation soars in Mexico, southwestern US
In a new weekly update for pv magazine, Solcast, a DNV company, reports that areas across Mexico and Southern Texas saw reduced cloud, leading to 120-130% of average September Irradiance. Meanwhile, storms and a ‘Bomb’ cyclone caused by persistent low pressure over British Columbia delivered cloudier conditions, leading to irradiance as low as 70% of long term averages.
Large-area perovskite-silicon tandem PV cell hits record efficiency of 25.1%
US scientists have achieved a breakthrough in PV cell tech by creating a 24 cm2 perovskite-silicon tandem solar cell. It positions a lithium fluoride interlayer between a hole transport layer and the perovskite absorber to reduce shunting losses.
New opportunities for 4-hour-plus energy storage
Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the US power grid on the back of a potential shift to net winter demand peaks, says the US National Renewable Energy Laboratory (NREL).
Northvolt to open battery factory in Canada
Northvolt says it will use a circular economy approach to achieve 60 GW/h of annual cell production in Quebec, Canada, with a focus on assembling batteries for the US automotive market.
Grid-forming inverters can enable grids with renewables
As renewable energy generation grows, demand is rising for grid-forming inverters to deliver the same functions as traditional rotating synchronous generators. The UNIFI Consortium is now taking the lead in advancing the development of this new inverter technology.
Integrating sky images, global solar irradiance into solar forecasting algorithms
A research team in the United States has created a novel approach to integrate raw sky images and global solar irradiance measurements, solar nowcasting, and intra-hour forecasting. The methodology utilizes low-cost radiometric IR cameras instead of expensive ceilometers.
Mitsubishi testing 5.5 MW pressurized alkaline electrolyzers in Japan, Norway
Mitsubishi has conducted short-term validation tests of its 5.5 MW pressurized alkaline electrolyzers in Norway and long-term validation tests in Japan. It plans to incorporate the design of these two single-stack pressurized alkaline electrolyzers into a US project.
U.S. utility-scale solar to more than double installations year-over-year
Over 10.4 GW was deployed in 2022, while 2023 totals may exceed 24 GW, said Lawerence Berkeley National Laboratory.
Weekend Read: The solar-battery-EV dream
For those who combine solar, batteries, and electric vehicles (EVs) at home, driving on sunshine is a realistic goal. However, there are many factors to consider when analyzing the economic payoffs, as well as the technical possibilities and limitations of such systems.
