ACE One - cookstove, solar panel, battery, LED bulb, and companion app

AFRICAN CLEAN ENERGY

A cookstove. A solar home system. A data platform.
One device.

The ACE One is a biomass gasification cookstove, an integrated solar panel and battery for lighting and phone charging, and a connected device that records every cooking session for carbon MRV.

One purchase. Three capabilities. Fifteen years of deployments across five countries.

HOW THE ACE ONE WORKS

Three systems, engineered to work together.

Clean cooking

Biomass gasification with fan-driven combustion. Burns nearly all types of biomass - pellets, briquettes, corn cobs, coconut shell, bamboo, sticks. Dramatically reduced smoke and fuel consumption.

Solar electricity

Integrated solar panel and battery provide LED lighting, phone charging, and small appliance power. Addresses the full spectrum of household energy needs alongside cooking.

Digital monitoring

Onboard microprocessor logs every cooking session. Data syncs through ACE Connect to support PAYGO payments, customer service, and carbon MRV. Every device is a data point.

WHY COOKING MATTERS

Cooking is the energy load. Electricity is a rounding error.

Thermal (cooking) Electric
95-99% of household energy demand
1-5%

The real energy load

Cooking dominates household energy use in emerging markets. One hour of cooking consumes ~1,000× the energy of one hour of lighting.

What solar home systems solve

Lights and phone charging are a fraction of the problem. Solar home systems alone cannot solve cooking energy demand.

MULTI-FUEL

Burns what's local.

Most competitors are pellet-only. The ACE One burns nearly all types of biomass, so households use whatever fuel is locally available.

THE GLOBAL CHALLENGE

Clean cooking is the largest mitigation opportunity nobody talks about.

2.4B

people worldwide still rely on traditional cooking methods

2.5Bt

CO2 emitted annually from traditional cooking

4M+

premature deaths per year from indoor air pollution

ACE addresses all three dimensions - health, climate, and energy access - through a single integrated system backed by device-level data.
