The Japanese conglomerate and the Osaka Metropolitan University are testing an aquifer thermal energy storage system that directly uses 10,000 m3 of groundwater stored at 5 C in a cooling well. It is intended to store renewable energy and produce cooling for air conditioning in the summer or heating for the winter.

Analyst Thema Consulting Group has calculated the impact of rapid expansion of battery storage systems in Germany and found they will help stabilize solar prices by reducing the number of negatively-priced-electricity hours – but will cannibalize their own revenue in doing so.

10 kWh sodium-metal-chloride batteries will be build at new site in Lancaster, England. Start-up LiNa is targeting markets with harsh climates during initial rollout and intends to produce 100 kWh systems following 10 kWh trial projects.

While Brazil wastes billions of real on curtailment, the electricity sector is demanding urgent action on an energy storage capacity reserve auction which is now not expected until 2026. ‘What is missing is the courage to unlock the market,’ said Greener CEO Marcio Takata.

JinkoSolar expects the PV market transition to last until 2027-28 due to negative power prices and project delays in Europe. In an exclusive interview with pv magazine, Vice President Europe Frank Niendorf says growth will recover as storage and hybrid systems expand and consolidation progresses.
