China new energy storage tops 100 GW as lithium overtakes pumped hydro
China’s new energy storage capacity exceeded 100 GW by June 2025, with total installations reaching 164.3 GW, surpassing pumped hydro additions amid accelerating deployments and changing market dynamics, according to the China Energy Storage Alliance (CNESA).
Feasibility assessment for deploying PV panels on tram tracks
New research from Poland has suggested installing 891 PV panels along the entire tram platform and inter-track spaces of four major transportation hubs. The analysis showed that the PV system could power all of the city’s tram stops, the passenger information system, and meet 10% of demand from service depots.
Turbulent times for US energy storage
US President Donald Trump signed the One Big Beautiful Bill Act (OBBBA) on July 4, striking down key Inflation Reduction Act measures for energy storage and leaving the sector bracing for turbulence.
Spain’s CIUDEN tests 5.8 MWh sodium‑sulfur battery with solar and hydrogen
Spanish company CYMI has completed operational testing of a 5.8 MWh sodium‑sulfur (NaS) battery at the City of Energy Foundation’s (CIUDEN) Integra2H2 project, integrated with a 2.1 MW solar plant and two electrolyzers to produce green hydrogen.
Austria allocates €12 million for solar-plus-storage rebates
The Austrian government had budgeted €12 million ($14 million) for a second funding round but wants to finance successful applications and bring 220 MW new solar and 200 MWh of storage online.
SolMicrogrid to buy near-complete US solar, microgrid projects
SolMicrogrid has launched an energy-as-a-service (EaaS) program to acquire near-complete solar and microgrid projects, offering developers upfront capital while providing commercial and industrial customers with long-term discounted renewable power without ownership costs.
German researchers develop recycling for dry-processed Li-ion batteries
Researchers at the University of Münster have developed a mechanical recycling process for production scrap from the dry processing of lithium-ion batteries. The method operates without solvents, preserves material properties, and allows the recycled cathode powder to be directly reused in electrode manufacturing.
Dominican Republic tenders up to 600 MW solar, wind with mandatory storage
The Dominican Republic has launched a tender for up to 600 MW of solar and wind capacity, requiring projects to include at least four hours of battery storage to support stability in the National Interconnected Electric System (SENI).
Central African Republic starts building 50 MW of solar with 10 MWh of storage
UAE-based Global South Utilities has begun construction on a 50 MW solar project with 10 MWh of battery energy storage systems (BESS) in the Central African Republic.
How to control frequency fluctuations during PV plant deloading
Researchers in Egypt have developed new control strategies for managing frequency fluctuations during deloading of a photovoltaic plant. The proposed methodology combines a proportional–integral controller along with a rate of change of frequency controller.
