What African Clean Energy does
African Clean Energy (ACE) designs, manufactures, and distributes the ACE One, an integrated clean-cooking device combining a fan-driven biomass gasification cookstove with a 10W solar panel and 32Wh LiFePO4 battery, plus an onboard microprocessor that logs every cooking session. The device supports eight biomass fuel types (pellets, briquettes, corn cobs, coconut shell, bamboo, sticks, agricultural waste, animal dung) and is paired with two mobile applications: ACE Connect (consumer-facing, for PAYGO payments, fuel ordering, and usage data sync) and ACE Catch (internal field workforce tool for sales, delivery, and maintenance). ACE operates its own manufacturing facilities in Lesotho (Ha Thetsane, 2012), Cambodia (Siem Reap, 2020), Uganda (Gulu, 2022), and Kenya (Kwale, 2025), with a fifth assembly footprint planned for Senegal, and is held under the Netherlands-incorporated parent ACE Energy Holdings BV.
The company sells primarily to rural households in Sub-Saharan Africa and Southeast Asia through a hub-based direct-sales model backed by PAYGO mobile-money repayments (MTN, Safaricom, Vodacom, Wave, ABA Bank). Revenue is generated from hardware sales and consumer finance, but the higher-margin component is the sale of verified carbon credits under Article 6 of the Paris Agreement and Gold Standard certification, monetised through sovereign buyers such as the Senegal-Switzerland bilateral programme. Distribution is supplemented by NGO and government partnerships (notably IFAD-funded WAMCOP in Lesotho) and coverage of ~48,000 data-enabled household deployments.
ACE has deployed 100,000+ units across five countries (Senegal, Kenya, Uganda, Cambodia, Lesotho) and employs approximately 120 staff globally. Leadership is founder-led (Ruben Walker, Founder and CEO; Tarren Engel, CFO; Daniel Walker, COO), and the company has been recognised with the EY Impact Entrepreneur of the Year (2021) for Ruben Walker. The business model is built on a "deploy-capture-verify-earn-scale" loop in which each installed stove generates compliance-grade carbon credits over a 10+ year operational lifetime, with credit volume compounding as the deployed fleet grows.

African Clean Energy business model
Business model- GTM type
- B2C
- Offering type
- Hardware or Manufacturing
Revenue model
- Carbon Credits (Article 6 Compliance): Each ACE One stove generates verified carbon credits for its full operational lifetime (typically a decade or more). Year one stoves continue to yield credits in years two, three, and beyond. As the fleet grows, annual credit volume compounds. Credits are sold to compliance buyers under Article 6 of the Paris Agreement. Senegal program is structured under the Senegal-Switzerland bilateral agreement with signed compliance carbon contract from day one.
- Clean Cooking Device Sales: ACE One hardware sales to households in emerging markets across five countries. Consumer finance enabled through PAYGO mobile money payments. Senegal is the flagship market by forecast revenue.
- Consumer Finance (PAYGO): Mobile money-based PAYGO repayment system for cookstove purchases. Supports loan repayment processing through mobile money providers including MTN, Safaricom, Vodacom, Wave, and ABA Bank. Historically funded customer loans through third-party financiers such as Kiva Microfunds.

African Clean Energy competitors and assessment
Company assessmentDirect peers
- BioLite: BioLite manufactures biomass cookstoves with integrated thermoelectric generation for charging — the most direct peer to ACE's biomass gasification cookstove with integrated solar/battery power. Operates across sub-Saharan Africa and South Asia with a comparable household energy access mission and direct-to-consumer field distribution.
- BURN Manufacturing: BURN Manufacturing designs and produces biomass and clean cookstoves distributed in East Africa (Kenya, Uganda, Tanzania) with comparable manufacturing-plus-distribution model targeting rural households and a similar carbon credit monetization thesis.
- ATEC: ATEC produces and distributes biomass gasification cookstoves for emerging markets including Cambodia, using a similar fan-driven combustion approach and PAYGO mobile-money model with a near-overlapping target customer demographic in Southeast Asia.
- EcoZoom: EcoZoom manufactures fuel-efficient clean cookstoves for distribution in emerging markets globally, with comparable products addressing household air pollution and similar customer base across sub-Saharan Africa and Southeast Asia.
- Inyenyeri: Inyenyeri delivers clean cookstoves and processed biomass fuel to Rwandan households using a stove-and-fuel subscription model with directly comparable carbon credit revenue stacking and rural last-mile distribution in an African emerging market.
- Sistema.bio: Sistema.bio distributes small-scale biogas biodigesters that convert biomass to cooking gas and organic fertilizer for smallholder farmers in Mexico, Kenya, and other emerging markets — comparable as a biomass-to-clean-cooking solution with rural distribution in emerging markets.
Broad incumbents
- M-KOPA: M-KOPA is a larger PAYGO energy provider in East Africa (Kenya, Uganda, Tanzania, Nigeria) offering solar home systems and cookstoves on mobile-money financing — directly comparable PAYGO business model and East African footprint, with a broader product mix and larger balance sheet.
