The Alliance seeks to address environmental, health, and livelihoods impacts of cooking with solid fuels through culturally-appropriate clean and efficient cooking technology which meets user needs. The variety of available cooking technologies reflects economic and sociocultural factors and energy requirements.  

Within each category of stoves, there are a range of designs and performance.  More information on specific stove designs, including characteristics, prices, and performance, is available through the Clean Cooking Catalog.

Charcoal

Traditional and improved stoves are available for using charcoal fuels. Because traditional production of charcoal has serious environmental impacts, improving the efficiency of charcoal stoves can minimize these impacts. Burning charcoal tends to release a lot of carbon monoxide (CO), and some improved charcoal stoves are designed with the goal of reducing CO emissions.
Fuel Types used

Chimney

Chimneys are structural components that provide ventilation of gas and smoke from the stove to the outside the home. While chimneys do not necessarily reduce total emissions, they can eliminate build-up of smoke in the kitchen and personal exposures to indoor air pollutants, especially when integrated with less advanced solutions. The effectiveness of chimneys depends in large part on maintenance.
Fuel Types used

Electric/Induction

Electric stoves convert electrical energy into heat for cooking. Use of electric stoves is limited to areas that have access to electricity, which can exclude rural communities. Induction stoves are a type of electric stove that produce heat when a high-frequency magnetic field comes into contact with compatible cookware, with no flames or emissions.
Fuel Types used

Ethanol/Alcohol

Ethanol is a liquid biofuel that can be made from a variety of feedstocks including sugary materials (e.g. sugar cane, molasses, sugar beet, or sweet sorghum), starchy materials (e.g. cassava (manioc), potatoes, or maize), or cellulosic materials (e.g. wood, grasses, and many agricultural residues) using a variety of conversion processes. Many new feedstocks are under development, such as algae, kelp and other wild or non-cultivated crops.
Fuel Types used

Fan/Forced Air

Many stoves include a fan, powered by a battery, an external source of electricity, or a thermoelectric device that captures heat from the stove and converts it to electricity. When optimized, this fan blows high velocity, low volume jets of air into the combustion chamber, which results in more complete combustion of the fuel.
Fuel Types used

Gas/Biogas/Liquid Petroleum Gas (LPG)

The properties of liquid and gas fuels tend to be efficient and clean burning, even in conventional low-pressure gas burners. Liquefied petroleum gas (LPG) is delivered to the household in cylinder/canisters. Access to this clean burning fuel type is increasing in the developing world, primarily in urban areas. To increase use of LPG, availability and affordability (stove, ongoing fuel requirements, and deposit for the gas canister) are challenges that need to be addressed. Biogas, produced from household- or community-level plants that convert organic waste material into combustible methane gas, is another clean fuel option for gas stoves.
Fuel Types used

Gasifier/TLUD

Gasifier stoves force the gases and smoke that result from incomplete combustion of biomass fuels back into the cookstove's flame, until almost complete combustion has occurred, resulting in very few if any emissions. Gasifier stoves are also known as Top Lit Updraft (TLUD) stoves because some fuel is lit from the top of the stove, which forces combustible gases to pass through the flame. Gasifier stoves can also include a fan, to improve mixing of flame, gas, and smoke and to reduce emissions.
Fuel Types used

Griddle/Plancha

Plancha (griddle) stoves are designed for areas of the world where a hot flat surface is required to prepare meals, for example tortillas in Mexico and Central America. The plancha stove is designed to enclose the fire, direct hot flue gases to the metal or stone surface for efficient cooking, and often to vent any emissions via a chimney. Designs vary from built in place models to prefabricated modular stoves that are easy to install.
Fuel Types used

Rocket/Side-Feed

Rocket stoves have an insulated, L-shaped combustion chamber that improves combustion of gases and smoke inside the stove. Rocket stoves also incorporate design elements to improve heat transfer efficiency and to direct the flow of hot gases to the pot or griddle using insulation and narrow channels. Production of rocket stoves can range from centrally mass-produced products to locally produced artisanal products.
Fuel Types used

Solar

Solar cookstoves, often called solar cookers, can be used in areas where solar energy is abundant for most of the year, typically between 30 degrees north and south of the equator, where much of the developing world is located. There are several types of solar cookers – panel cookers with a clamshell shape, box cookers which fully enclose the pot, parabolic cookers that resemble a satellite dish, and vacuum tube cookers that work like greenhouses. Solar cookers have zero emissions, typically require changes to how and when users can cook and multiple devices to meet a households cooking needs.
Fuel Types used

Traditional

Traditional stoves, including rudimentary open fires (e.g. three stone fire), are locally produced using available and low cost materials such as stones, ceramics, clay and bricks. These stoves also utilize readily available fuels such as wood or charcoal.
