Tokyu Corp. and partners will supply Tokyu Railway with newly built solar power under a corporate power purchase agreement (PPA), covering about 30% of traction electricity demand.

Wood Mackenzie’s latest analysis explores how 13 of the world’s leading power markets are impacted by the current fuel crisis, with those most reliant on fuel imports facing the greatest risk exposure. The consultancy says the average cost of generation is set to increase by $2.30/MWh across these 13 markets if a de-escalation of the conflict enables fuel price moderation in the latter half of 2026, increasing to an average of around $8.30/MWh if current elevated price levels persist through the year.

A Japanese–Chinese team developed a titanium molten salt redox-flow battery using abundant titanium ions and molten salt electrolytes to enable high-voltage, fast, and stable grid-scale energy storage. The system demonstrates high efficiency of over 97%, strong cycling stability, and improved cost and scalability compared to vanadium-based batteries, with further optimization underway.

Neoen has announced two battery energy storage system (BESS) projects in France and Japan, expanding its footprint in both markets with installations totaling 348 MW and 896 MWh.

Japanese researchers developed a molybdenum-based spin-flip emitter that efficiently harvests triplet excitons from singlet-fission tetracene dimers, producing strong near-infrared emission. This approach could boost solar cell efficiency and enable new quantum technologies by converting otherwise “dark” excitons into usable light.

The two major developers plan to establish a joint venture company with equal ownership that will be their sole vehicle for building, owning and operating both existing and future solar, storage and wind projects across nine Asian countries.

Kyocera Corporation will begin to supply electricity generated from its solar assets to Cosmo Energy Solutions from next month. It has also entered into a separate power purchase agreement with Cosmo Eco Power for energy generated from a 48 MW wind farm.

GlobalData says hydrogen capacity could reach 82.3 million metric tons per annum (mtpa) by 2030, while Topsoe has ended supply agreements with First Ammonia.

Designed for commercial and multi-residential buildings, the Aqua‑G EVO heat pump can replace gas boilers, cascade up to eight units, and integrate with Panasonic’s complete HVAC ecosystem.

A Japanese consortium is piloting agrivoltaics using film-type perovskite solar cells over rice paddies to study energy generation alongside crop production. The three-year project will assess impacts on rice yield, land use, and emissions while testing the technology’s performance and commercial viability.
