Iberdola-led project develops solid-state battery module for stationary storage
Basquevolt and Bcare have successfully developed and integrated the first solid-state cells into a module for stationary applications, accomplishing this within the Iberdrola-led ASTRA-CC project (2023–2025).
GES rolls out manganese-hydrogen battery with significant cost edge over lithium-ion
The Italian company said the manganese-hydrogen battery it has developed represents an advanced solution for long-duration energy storage. The technology enables energy to be stored for many hours or even days, overcoming the structural limitations of lithium-ion batteries.
Researchers achieve record perovskite solar module stability under light, heat, and UV stress
An international research team has developed a new two-dimensional perovskite interlayer based on a co-crystal engineering strategy for more robust perovskite films. It demonstrated improved performance in small area perovskite solar cells and, in a 48 cm2 module, contributed to retain 95% of initial efficiency after 5,000 h.
Dutch long-duration energy storage project targets sub-€50/kWh costs with innovative technologies
The SLDBatt project brings together TRL 7 battery technologies – including molten sodium‑salt, saltwater acid–base flow, and hydrogen–iron flow batteries – to deliver an innovative and cost-effective long-duration energy storage solution.
High-capacity gutter for efficient solar panel drainage
French company Dal’Alu has developed a high-capacity aluminum gutter designed to efficiently collect and channel rainwater from large roofs and solar panels. Its on-site profiling, modular components, and durable construction reportedly ensure rapid installation, long-term performance, and compliance with current building standards.
Neoen’s battery to pioneer grid-forming services on French transmission network
At a major battery project, RTE and Neoen are trialing an inverter retrofit, marking a first for grid-forming services on France’s transmission network.
Norway adds 117 MW of solar in 2025
Norway’s solar market experienced a slowdown in 2025, particularly among residential installations. The outlook for 2026 looks more optimistic, thanks to policy reforms supporting larger projects and continued demand from commercial and industrial customers.
Luxembourg revamps subsidies for solar on residential buildings
Luxembourg’s new subsidy scheme for solar installed on residential buildings by an approved installer deducts the financial aid from the installer’s invoice, meaning customers no longer have to wait for reimbursement.
Swiss researchers improve electrolyte design for long-life solid-state batteries
A Swiss research team has developed a low-temperature sintering and interface-coating process that significantly improves the durability of argyrodite-based solid-state batteries. The approach delivers high ionic conductivity and long cycle life, retaining 75% of capacity after 1,500 cycles.
France awards 40 MW of solar projects in non-interconnected zones
France’s fourth PV tender for non-interconnected areas allocated 40 MW across Corsica, Réunion, and French Guiana. The weighted average tariff fell to €92.04 ($107.59)/MWh, while overall subscription remained well below the 99 MW available.
