01

Terawatts of clean energy, reimagined

We're building the world's first large-scale battery technology based on industrial waste. It's safe, durable, and designed to scale with the electrification of everything.

02

Scaling with the world, not against it

Our system leverages existing industrial infrastructure and supply chains—no rare earths, no gigafactories, no complex logistics. Just chemistry, at scale.

03

A future that lasts a lifetime

With ultra-durable, refillable batteries built to last over 25 years, Carbo Energy delivers a sustainable, equitable solution to power homes, grids, and industries—forever.

Waste-based batteries with the performance and scale of lithium — without the cost, risk, or resource limits.

Our redox flow system delivers grid-scale storage using abundant industrial byproducts, enabling clean, reliable energy—fast.

2035

Waste-based energy storage is the backbone of a fully electrified world. As renewable generation scales, storage becomes the limiting factor. Our batteries enable a reliable, affordable, and resilient grid—powered by circular chemistry, not critical minerals.

To scale renewables to terawatts and eliminate intermittency, we need storage that lasts decades—not hours.

Carbo's waste-based batteries deliver long-duration, grid-scale energy storage that's clean, affordable, and built to last.

Our modular flow battery system stores energy using recycled industrial byproducts—without rare earths, thermal risk, or degradation.

Built on decades of chemical engineering and advances in circular economy tech, we're pioneering a radically more scalable approach to energy storage.

We start by sourcing abundant waste streams from existing industries. Then, we convert them into high-density electrolytes that power a new generation of safe, long-duration batteries.

Unlimited Potential with Waste-Based Storage

Workforce ready

The global chemical and industrial sectors already have the talent needed to scale Carbo batteries. Our systems are built with familiar processes—pumping fluids, managing tanks, maintaining valves—making the transition seamless.

Infrastructure ready

From industrial waste streams to manufacturing and distribution networks, our technology integrates into the infrastructure that already exists. No rare earths, no gigafactories—just smart reuse and modular deployment.

No geopolitics

Carbo batteries are built from abundant local materials. By removing dependence on lithium, cobalt, and fragile supply chains, we make energy storage truly equitable and resilient, anywhere on Earth.

Environmentally sound

Our chemistry is circular, our system is refillable, and our impact is minimal. Carbo batteries are non-flammable, fully recyclable, and require a fraction of the land, energy, and materials of lithium-ion or pumped hydro.
