Long duration energy storage has spent years sitting in the “we’ll need it someday” category. Not anymore. As grid strain grows, data center demand surges, and reliability becomes a boardroom issue, long duration storage is starting to move from interesting concept to urgent solution.

Recorded live at Intersolar and Energy Storage North America, this panel brings together Anna Siefken of the LDES Council, Aric Saunders of Noon Energy, Tristan Bannon of CellCube, and Andrew Friedenthal of E-Zinc. With Nico Johnson leading the conversation, the group digs into what is changing in the market and why more buyers are finally paying attention to long duration storage.

This episode is not just about technology. It is about what happens when the grid needs more than incumbent batteries can supply. The panel explores how vanadium flow, zinc-based systems, and other long duration approaches could support resilience, replace diesel, firm renewables, and help planners think beyond the standard four-hour battery playbook.

Expect to learn:

🔹 Why long duration storage is finally gaining real commercial momentum

🔹 How data centers, resilience needs, and grid volatility are accelerating demand

🔹 What makes zinc, vanadium, and other chemistries worth watching

🔹 Why procurement rules should focus on the problem to solve, not the technology to favor

If you want a clearer picture of where storage is headed after lithium-ion, this conversation is a strong place to start. It is practical, candid, and full of insight from leaders building the next layer of the grid.
