Biogas can be used as a cooking fuel by connecting biogas stoves or modified gas burners to the biogas supply. Biogas stoves are specifically designed to optimise the combustion of biogas and provide a reliable source of heat for cooking.

The table below displays the amount of biogas used by biogas stoves and for different cooking purposes.

Purposes	Litres _Biogas / hour	Source
Household cooking stove	200 – 450	(GTZ )
Consumption per person and meal	150 – 300	(GTZ )
