Japan’s NGK discontinues manufacturing of sodium-sulfur batteries
The manufacturer cites rising material costs, heightened competition from lithium-ion batteries, and the slow uptake of long-duration storage technologies as the reasons for the decision.
Spain approves new decree to accelerate storage and grid modernization
Spain’s Council of Ministers has approved a royal decree to promote energy storage, accelerate electrification, and tighten oversight of the national grid, says the Ministry for the Ecological Transition and Demographic Challenge (MITECO).
Dubai expands storage in seventh phase of world’s largest solar park
Dubai Electricity and Water Authority (DEWA) says the seventh phase of the Mohammed bin Rashid Al Maktoum Solar Park will pair 2 GW of solar with 1.4 GW of storage, up from 1 GW, after receiving 49 expressions of interest under its 2050 clean energy plan.
Field trial shows third-party control of residential heat pumps can provide grid flexibility
UK researchers find that smart, centrally controlled air-source heat pumps could slash peak electricity demand. The technology not only keeps homes comfortable but also boosts grid flexibility and cuts emissions.

European PPAs held back by diverging price expectations, says Pexapark
Pexapark has attributed a slowdown in the number of power purchase agreements (PPAs) signed across most of Europe’s leading markets to a lack of pricing consensus between buyers and sellers.
Battery projects dominate Belgium’s 2025 capacity market awards
Battery storage secured nearly all new-build capacity in Belgium’s latest capacity market auctions, cementing its central role in the country’s power supply plans through 2030.
Japanese utility uses Sharp PV-linked home batteries for grid balancing
Japanese utility Tohoku Electric Power is using Sharp’s residential batteries and AI-powered energy management systems to balance grid demand and optimize household solar energy use. Customers in the program can earn points redeemable for local products.
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.
