Product Description

Designed by engineers at Lawrence Berkeley National Lab using the knowledge and input of local Darfuri women, the Berkeley-Darfur stove is a highly efficient wood-burning cookstove adapted to local pots, customs, and cooking practices. It has a stainless-steel body and a maximum pot capacity of 15 litres.

Market Suggested Retail Price


Distributors / Implementing Organizations

Potential Energy works in collaboration with over 20 local women's organizations in Darfur for the distribution of the stoves. Potential Energy employs both humanitarian and market-based approaches within flexible installment plans, and by donations to vulnerable populations without a regular form of income. Further organizations, such as Impact Carbon, Oxfam America, Plan Canada/Plan International, Sustainable Action Group, USAID have taken part.

Manufacturing/Building Method

A hybrid approach that combines both mass manufacturing and local production is used. The stoves are manufactured as flat-kits in India and then shipped to Sudan where they are assembled in local workshops. Over 35 people play a role in assembling, selling, and distributing the stoves within a production process that includes high-quality control procedures throughout. A video is available about the assembly shop in Darfur, Sudan.

Design Specifications

Design specifications include a Rocket-type stain steel-body with a combustion chamber at the bottom. It weighs 5.5 kgs and its dimensions (LxWxH) are 37 x 17 x 30 cm. Materials for local assembly: rivet guns pliers bending tools.

Technical Support

Potential Energy trains local workers to assemble the stoves at a 'rate of 100 each day' in the Berkeley-Darfur Stove assembly shop. Assembly manual available in English and with photos of the processes is given to partners doing the assembly. Additionally, Potential Energy gives live training and 24-hour support to partners worldwide. The stove comes with a user guide and with photos of the process of lighting, cooking and cleaning, safety recommendations and terms of the guarantee.

Replacement Components

Yes. Technical items such as rivets, pliers, and bending tools can be used to fix/replace some parts.


The product has a 1-year warranty and an expected lifespan of 5 year.  The stove will be replaced in case of manufacturing fault within the first year of use. Stoves damaged by poor handling and use cannot be repaired or replaced by this warranty. After 1 year, stoves may still be repaired for a fee.

Manufacturer Specified Performance Parameters

Darfur Stove reduces fuel consumption from 33% to 17% which results in a money saving of 0.97 USD/day in firewood costs. Over the lifecycle of the stove (5 years), the saving rises to 1,770 USD per household. Within the number of stoves distributed, collective firewood savings are estimated to have created more than 79 USD million in savings.  

Vetted Performance Status

In 2013, Potential Energy partnered with UC Berkeley’s Center for Effective Global Action to conduct a rigorous evaluation of stove use by installing heat sensors on 180 stoves and continuously monitored use for several months. For 2018, a total of 8 test have been conducted by a variety of independent labs. Data is available for download via the Clean Cooking Catalog. 


Safety is unrated in the Clean Cookstove Catalog. Guidelines provided by Potential Energy should be followed to avoid burns and spill-overs when manipulating the stove.
