Varta launches Varta.wall DC high-voltage battery
Varta says it now expects high demand for its Varta.wall DC high-voltage battery. It initially presented the product at Intersolar 2022, but has struggled with its market introduction.
PV-driven drip irrigation system with compressed air storage
The proposed system uses compressed air to store energy, as well as for the prevention of clogging in the irrigation tubes. Two experimental systems were built and tested in China and clogging was reduced by up to 93%.
New residential storage system from Germany with 12,000 charging cycles
German manufacturer EKD says its new Ampere.StoragePro E3 battery uses lithium-iron phosphate cells and can be cascaded to reach up to 231 kWh.
EUPD Research expects 11 GWh of home storage to be added in Europe in 2024
According to the Bonn-based analysts, the momentum for home battery storage systems with a capacity of up to 20 kWh is driven by emerging markets such as Poland and Hungary. In Germany, however, they expect a 5% drop in new installations compared to the previous year.
Giga Storage, TenneT to optimize use of grid capacity
Under the first-ever time-limited contract in the Netherlands, Giga Storage will have the right to take electricity from the grid or feed it back in from its 300 MW/1,200 MWh Leopard project at least 85% of the time.
Uzbekistan set for large solar-plus-battery system
ACWA Power plans to build a 500 MW solar plant and a 500 MWh battery energy storage system in Uzbekistan under a project proposed by the Asian Development Bank (ADB).
Nanoparticles, phase-change materials in PVT systems
Scientists have used varying levels of Al₂O₃ and ZnO paraffin wax to improve the electrical and thermal performance of a photovoltaic-thermal (PVT) system. They have also developed a prediction model for this specific combination of hybrid nano-phase change materials.
Sineng Electric turns on 150 MW/300 MWh of storage in China
Sineng Electric has switched on a 150 MW/300 MWh standalone energy storage station in Guangxi, China, featuring battery energy storage system (BESS) containers, a central power conversion system (PCS), and a booster station.
Natron Energy to build GW-scale sodium-ion battery factory in U.S.
The new planned manufacturing facility will produce 24 GW of Natron’s sodium-ion batteries annually. Natron says its batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable. The plant will be the first double-digit GW sodium-ion plant in the United States.
Netherlands posts more negative energy prices
The Netherlands has recorded more hours of negative energy prices between Jan. 1 and Aug. 17 than it did in all of 2023. Dutch research firm Stratergy has noted a clear correlation between expected solar and wind energy and negative hourly prices in the day-ahead market.
