Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Too early to adopt

Why
Pre-commercial with zero operating plants, an enormous demo-to-full-scale gap, low round-trip efficiency for power, and significant geographic + permitting constraints; promising long-duration potential but unproven.
Next
Reassess after the NREL/Premier Resource Management Kern County 100 kWe demo actually operates and publishes measured round-trip efficiency and storage duration (post-2027); track the second Kern Front Oil Field industrial-heat demo.
