The statistics on the effects of cooksmoke seem overwhelming, but it’s not all bad news. Unlike for many other global problems, the solution to this problem is simple. It can be realised instantly and revolves around a desirable, multi-functional tool with the potential to improve health, the environment, and combat poverty on a truly global scale. Creating a solution and making it accessible to those in developing countries who may not currently have access to an alternative, can significantly alleviate the problems resulting from open-fire cooking.

Our solution is ACE 1 Ultra-Clean Biomass Cookstove.


  • ACE 1 is at the vanguard of stove innovation, using gasification to smokeless burn almost any type of biomass. This helps reducing household pollution and related diseases, thus improving health condition of women and children in developing countries. Moreover, drastically reducing the risk of house fires, our stove is able to avoid the numerous deaths occurring for this reason.

  • From an environmental perspective, ACE 1 is so efficient it requires around 70% less fuel to run, compared to traditional cooking methods. In addition, its gasification process ensures almost complete combustion of fuel, eliminating black carbon, which is a significant contributor to climate change.

    So what does The ACE 1 burn?

    Our cookstove has been designed to burn a wide variety of biomass, including found fuels such as sticks and twigs, cowdung, and corn husks. Crucially, it has been designed to also burn processed biomass fuels like wood pellets and briquettes, which are made from waste materials like sawdust, forestry waste, or agricultural waste. This means customers in urban areas can be given access to sustainable fuels, replacing current unsustainable ones like paraffin and charcoal. The latter, charcoal, can in fact be burned cleanly and efficiently in the ACE 1 too, but due to its inefficient production process, we are keen to replace it with sustainable alternatives. Combined with available biomass, the ACE 1 presents a cost-effective and environmentally sound fuel solution.
    It is also incredibly powerful. The fact that it lights up quickly and it is almost immediately ready to cook, in addition to the fact that, thanks to its refractory ceramic tiles, it retains heat for longer, are some of our customers’ most loved features.

  • In line with African Clean Energy’s belief in socially responsible business practices, our stove is assembled locally to generate employment where the stove is most needed. We plan to use carbon credits as a tool to make the ACE 1 accessible to people with low incomes.


    Through geographically concentrated distribution methods, the revenue from the credits will be reinvested to benefit the end users, for example, to help pay for repairs and supplementary products, such as pellets. This means a long-term commitment to the communities where the cookstoves are being used and the creation of new local jobs.

    In addition, the increased use of pellets/briquettes as a result of the implementation of ACE represents the perfect opportunity for an additional source of income in communities where the stove is distributed. Our intention is to help local businesses experience a growth in demand for these affordable source of fuel. Finally, the DC connector and USB ports enable the stove to turn into an additional source of power – an incredible convenience for many households that are not connected to the grid or in places where electricity is too expensive. This will enable them to power lamps or charge mobile phones, which are used for money transactions. A solar panel and LED light are also add-ons that can provide extra energy and light to families who need it most.
