The Noah Stove is a gasifier that doesn’t burn wood to ash during the cooking process but gasifies it to charcoal. This can be reused for fire or it can be turned into biochar, an organic fertiliser that improves soil fertility long-term. An Noah Stove saves 1,9t CO2/ year compared to standard cooking processes.

Why Noah Stoves?

The inventor of the clay gasifier, an Ethiopian-trained clay expert, had a very simple insight: Wouldn’t it be great if poor women could earn money while cooking? Plus, the gasifier is made sustainably of clay, straw and water, and the burning chamber consists of used oil cans. The stove can be produced locally, creating local jobs. And it empowers women to make some money while cooking, providing not just food but future opportunities for themselves and their families.

The social background

80% of African women cook on open wood fires which is costly and leads to lung diseases and severe deforestation. Many aid organisations have developed energy-saving stoves, but adoption rates have generally been low.

Using charcoal as an organic fertilizer is an even more efficient use of wood and improves soil fertility. This in turn will lead to higher crop yields.
