Reaching data centers with long-duration energy storage

My Account

Submitted by Benjamin Campbell on

Key takeaways

  • Long-duration energy storage (LDES) previously deployed in isolated places with severe grid constraints and where importing fuel was expensive or transmission scarce, but AI data centers are driving new growth in LDES demand.
  • The AI load has outstripped transmission and natural gas generation, making the cheap, firm alternative that undercut LDES unavailable for now.
  • Capacity value is the engine.

Key takeaways

  • Lithium-ion (Li-ion) remains the main battery chemistry for battery energy storage systems (BESS), but sodium-ion (Na-ion) and flow batteries could soon see adoption as backup power storage.
  • Data centers can use software to distribute compute tasks across multiple sites and match workloads to available power.
  • Rapid improvements in processing architectures and algorithms, and the value proposition of BESS and other back-up systems, will evolve against this highly volatile back

Why are batteries becoming essential for AI data center load management?

Key takeaways

  • AI data centers combine huge power demands with rapid fluctuations, reshaping how operators, technology providers, and utilities shape infrastructure.
  • Data centers consume so much power that operators must consider how to match data center demand to utility supply instead of matching supply to demand.
  • AI data center power strategies must address four distinct but interrelated challenges: bridging short-duration outages, smoothing ultrafast load fluctuations, managing peak demand, and

Uncompromising high-performance thermal protection in battery energy storage systems with GORE battery insulation technology

Battery energy storage systems (BESS) face critical safety challenges in managing thermal runaway events while maintaining optimal performance. Traditional thermal barriers may stop working well during thermal runaway, when both temperature and pressure get very high. This white paper looks at how a new technology from W. L. Gore & Associates, Inc.

Understanding your customers is essential for designing effective EV programs and services. To help you engage with your customers and increase EV adoption and program participation, E Source designed a residential customer survey to gather insights from three key residential customer segments: EV owners, customers considering purchasing an EV, and customers not considering an EV.

Topics covered in the 2026 study include:
