A renewable energy system cannot run on short-duration storage alone. While lithium-ion batteries excel at balancing minutes and hours, they fall short when wind and solar underperform for days. This “multi-day gap” is one of the hardest problems in the energy transition, and a critical blocker to fully renewable grids.
Solving it requires storage that is not only long-duration, but also safe, affordable, and scalable without relying on scarce or geopolitically fragile materials. That combination remains rare.
ORE Energy was founded to close this gap.

We invested in ORE Energy at pre-seed because its technology directly addresses one of the most fundamental bottlenecks in the energy transition: long-duration, grid-scale storage. Its iron-air battery system can store electricity for up to 100 hours, enabling grids to ride through multi-day periods of low wind and sun.
This sits precisely at the intersection of deeptech and climate tech that defines our strategy. ORE Energy’s approach relies on abundant, non-toxic materials like iron, air, and water, making it inherently scalable, cost-effective, and resilient to supply-chain risk.
At this early stage, our role goes beyond capital. We support ORE Energy in industrial validation, system design, and sharpening the path from breakthrough chemistry to deployable infrastructure.

ORE Energy is building the foundations for a resilient renewable grid:
ORE Energy turns renewable intermittency from a liability into a manageable engineering problem.
