ZGR battery system kept one Spanish village powered during major Iberian blackout
A 160 kW / 250 kWh standalone battery system installed by Spanish manufacturer Zigor Corporación ensured uninterrupted power for the village of San Vicente del Monte during a major blackout that affected the Iberian Peninsula on 28 April 2025. The system, connected to the low-voltage (400 V) grid, supplied electricity to the entire village for more than five hours.
UGT Renewables to build 3 GW of solar in Iraq
UGT Renewables, a US-based developer, says it will build a 3 GW solar project in Iraq under a deal with the federal government that includes 500 MWh of storage and 1,000 km of high-voltage direct current (HVDC) lines.
Comparing thermal runaway behavior of sodium-ion, lithium-ion batteries
Scientists in Germany have analyzed the thermal runaway behavior of sodium-ion batteries and lithium-ion batteries inside a 10-L reaction vessel. They have thermally abused 30 samples, each under a different state of charge level, and have found that both types suffered from runaway when the charge is at least 50%.
