Ferrovolt
Multi-day storage using abundant, low-cost materials.
What they do
Ferrovolt builds grid-scale storage systems designed for 100-hour discharge using iron-based chemistry rather than lithium.
Why it's interesting
Huburb analysis — an editorial reading of the approach, not a sourced claim.
Round-trip efficiency is deliberately traded away for cost per stored kilowatt-hour — the right trade when the job is covering a still, cloudy week rather than an evening peak.
