Eos and TURBINE-X Partner for 2 GWh Private Power Grid for AI

Zinc-based battery storage leader Eos Energy and large-scale gas-fired power infrastructure developer and integrator TURBINE-X are developing behind-the-meter power systems purpose-built for AI data centers.

The “bring your own power” setup aims to develop power sources on faster timelines than traditional utilities can provide. TURBINE-X is targeting 2 GWh of deployments over the next three years, starting in 2027.

Rongke Power Launches 81% Efficiency Vanadium Flow Battery

Dalian Rongke Power has launched a 2 MW/8 MWh vanadium flow battery system that, per the company, is the highest-power single vanadium flow battery storage system in the world.

The system’s 62.5 kW stacks achieve DC-side efficiency above 81% even at high current density, scale modularly to over 10 MW, and come in at a physical footprint that’s about 28% smaller than the industry norm. Get the story in ESS News.

FAMU-FSU Researchers Develop Zinc-Ion Battery Designed for Scale

Researchers at the FAMU-FSU College of Engineering have developed a rechargeable zinc-ion battery in which the manganese dioxide cathode is grown inside the assembled cell via electrodeposition – eliminating the slurry mixing and drying steps that bottleneck conventional manufacturing. In addition, the battery includes a Kevlar-based hydrogel that handles dendrite suppression on the anode side. FSU News has the story. Full research in ACS Omega.

Virginia Mandates 20.78 GW of Long-Duration Storage

The U.S. state of Virginia has committed to adding 520 MW of long-duration energy storage by 2045, part of a broader 20.78 GW storage target. Read details in Energy Storage News, and read an analysis on the C2ES blog.

Eos’s DawnOS™ From Concept to Scale

Eos has released a white paper tracing the evolution of its DawnOS™ battery management system. For anyone working in battery R&D, it’s a useful window into how a commercial-scale system actually gets built and refined over time. Access it from Eos Energy.

Interview: Where Lead-Acid Fits in Grid Storage

The Battery Council International spoke with Di Wu, a chief research engineer and team leader at Pacific Northwest National Laboratory, about lead-acid batteries and their place in grid storage.

The conversation covers techno-economic assessment, remaining deployment barriers, and how lab findings get translated into something battery makers and regulators can put to use. Read the interview at Battery Council International.

Report: LDES’s Role in India’s Energy Evolution

The LDES Council has published a paper examining how long-duration energy storage fits into India’s evolving power needs — including the country’s push to source half its electricity from non-fossil fuels by 2030. Access the report.
