Fluence to supply Leag’s 4 GWh battery project, Europe’s largest, in Germany
Fluence Energy says it will supply a 1 GW/4 GWh battery energy storage system for German power producer Leag, marking both Europe’s largest such project and the company’s biggest single installation to date using its Smartstack platform.
Forschungszentrum Jülich achieves world record 23.08% efficiency for copper-metallized heterojunction solar cell
The cell reportedly exhibits only a 0.4% efficiency loss compared to a reference device that underwent full silver metallization.
Bosch starts up 2.5 MW hydrogen electrolyzer in Germany
German industrial group Bosch says the Bamberg facility complies with European Union renewable hydrogen rules and will produce over one ton of green hydrogen daily.
Eco Stor breaks ground on Germany’s largest battery storage project
Eco Stor says construction has begun on a 300 MW/714 MWh battery storage facility in Förderstedt, Saxony-Anhalt, now the largest such project under development in Germany.
Four-year testing finds heat pumps run efficiently even in older homes
Researchers at Fraunhofer ISE have tested various types of heat pumps in existing buildings across Germany over four years, finding that the systems achieved seasonal performance factors between 2.6 and 5.4. The team also showed that PV-driven heat pumps can boost self-consumption rates, particularly when paired with battery storage.
Sonnen launches trade-in program for old solar battery storage systems regardless of condition or manufacturer
The initiative by the Allgäu-based company targets owners of photovoltaic storage systems installed before the end of 2020. The value of the trade-in bonus depends on the capacity of the new Sonnen battery. Sonnen describes the campaign as a “targeted growth initiative in a new market segment.”
The Hydrogen Stream: Germany audit warns of missed H2 goals
Germany’s Federal Court of Audit (Bundesrechnungshof) says the nation’s hydrogen strategy is falling short despite heavy subsidies, while Pulsenics and Endua have launched the first commercial AI-based monitoring system to improve electrolyzer performance under fluctuating renewable power conditions.
World’s largest heat pump under development in Germany
The 162 MW project is being developed by German utility MVV Energie. The system will use water from the Rhine river as a heat source and is expected to generate heat with temperatures of up to 130 C.
Algorithm optimizes renewable power procurement in Germany
German electricity trader Flexpower has expanded its power purchase agreement (PPA) platform with an algorithm that calculates the most cost-efficient mix of renewable energy contracts and spot market purchases for industrial consumers.
Inverter protection system triggers permanent short circuit in under 1 millisecond
A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a fault. The generated short circuit remains intact during the fault, reliably protecting the components from overcurrent.
