Turning Flexibility into Strength.
The energy system is straining under its own rigidity.
We’re building the fix by making it flexible.
Bubble stores energy as compressed air — at 200 bar and 1,000 °C — safely, efficiently, and indefinitely.
A durable system built from air, steel, and stone - elemental, circular, and made to endure for decades.
Each Bubble system is designed specifically for daily PV firming - shifting energy across the 5–10 hour window where solar economics break down.
By relieving congestion and stabilising flow, it multiplies the value of every megawatt around it.
That’s engineering leverage: one focused intervention creating system-wide strength.
We design for permanence — turning volatility into reliability, abundance into utility, and the energy transition into something that lasts.
Together, these systems form a new kind of grid — a Ductile Energy System — elastic, resilient, and adaptive.
This is Bubble.
Where flexibility becomes strength.
Bubble is currently entering its first full-scale demonstration phase (TRL6), focused on proving integration, durability, and economics at asset scale.
