AI-driven electricity demand has triggered billions of dollars in clean-energy investment, including next-generation geothermal power, advanced nuclear reactors, and long-duration batteries. According to Sina Finance, developers are beginning to deploy long-duration storage systems at data centers, and experts said the move could help scale the technology and support greater use of renewable energy. Crusoe co-founder and President Cully Cavness said long-duration storage is an important part of the supporting technology stack for building AI infrastructure at an unprecedented scale. The company builds and operates AI data centers for technology giants. Long-duration storage refers to technologies that can store and release electricity for hours or even days, unlike traditional lithium-ion batteries, which typically provide power for only a few hours. According to estimates, at least 150 gigawatt-hours of new long-duration storage projects in the U.S. have been announced, permitted, or financed since early 2025, more than five times the total planned U.S. capacity at the end of 2024, according to BloombergNEF. In Arizona, Alphabet is working with Italy's Energy Dome on carbon dioxide storage batteries for 10 hours of storage. Crusoe Energy is working with Form Energy to deploy iron-air batteries, while Meta has reached an agreement with California-based Noon Energy to deploy a storage system that can store renewable energy for 100 hours.

CXMT announced at the 2026 World Manufacturing Convention that its fifth-generation technology platform has entered mass production. According to ChainCatcher, the company said the platform reduces the active area half-pitch of its memory array to 11.95 nanometers, raises the capacitor aspect ratio to 45:1, and lowers the core kinetic zone height to 6,762 nanometers. The company said the fifth-generation process platform significantly improves memory density and increases wafer output by more than 50% under the same conditions compared with the previous generation. A 24GB LPDDR5X product based on the platform has also entered mass production and is being used in mainstream domestic flagship smartphones.

Ethereum co-founder Vitalik Buterin said privacy is only truly dead if people give up on it, adding that he will not abandon privacy and will instead increase his efforts. According to ChainCatcher, he made the remarks in response to Paradigm CTO Georgios Konstantopoulos' question about what room remains for privacy development. Buterin previously updated Ethereum's roadmap in August, with quantum security, privacy protection, and native rollups listed as future priorities.
