“…Lebel et al [61] approximated that methane gas cookers emit 0.8-1.3% of the gas as uncombusted methane (a potent greenhouse gas) coupled with nitrogen oxides. Improving the combustion characteristics of these cookers is thus cardinal as has been demonstrated in the studies [62][63][64][65][66][67][68][69][70][71][72][73][74]. However, like advanced solid fuel combustion cookers, improving the efficiency of these cookers leads to more CO 2 emissions.…”

About 3 billion people use conventional carbon-based fuels such as wood, charcoal, and animal dung for their daily cooking needs. Cooking with biomass causes deforestation and habitat loss, emissions of greenhouse gases, and smoke pollution that affects people’s health and well-being. Hydrogen can play a role in enabling clean and safe cooking by reducing household air pollution and reducing greenhouse gas emissions. This first-of-a-kind review study on cooking with hydrogen assessed existing cooking technologies and hydrogen systems in developing country contexts. Our critical assessment also included the modelling and experimental studies on hydrogen. Renewable hydrogen systems and their adoptability in developing countries were analysed. Finally, we presented a scenario for hydrogen production pathways in developing countries. Our findings indicated that hydrogen is attractive and can be safely used as a cooking fuel. However, radical and disruptive models are necessary to transform the traditional cooking landscape. There is a need to develop global south-based hydrogen models that emphasize adoptability and capture the challenges in developing countries. In addition, the techno-economic assumptions of the models vary significantly, leading to a wide-ranging levelized cost of electricity. This finding underscored the necessity to use comprehensive techno-economic assumptions that can accurately predict hydrogen costs.

The present study analyses the emission mitigation ability of a Porous Media Combustion (PMC) technology based cookstove (𝐶𝑆 𝑃𝑀𝐶 ) compared to a Free Flame Combustion (FFC) technology based cookstove (𝐶𝑆 𝐹𝐹𝐶 ).Emission of pollutants i.e., PM2.5, PM10 and CO caused due to burning of fuels namely methanol, ethanol, kerosene and LPG in the kitchen environment are measured. The study incorporated exhaustive real-time indoor air quality (IAQ) measurements and presented the temporal variation of measured pollutant concentrations for 2 h (morning meal duration). In addition, 24 h average concentration of the measured pollutants is also compared with the limits prescribed in WHO guidelines for domestic settings. The results emphasised that the utilisation of 𝐶𝑆 𝑃𝑀𝐶 would help in improving the IAQ of the kitchen area by decreasing the concentrations of PM2.5, PM10 and CO.For 2 h duration measurements, the methanol cookstove based on PMC reduced the concentrations of PM2.5, PM10 and CO by 7.7%, 8.1% and 17.2% respectively, compared to FFC cookstove. Similarly, in the case of PMC based LPG cookstove ( 𝐶𝑆 𝑃𝑀𝐶 𝐿𝑃𝐺 ) and kerosene cookstove (𝐶𝑆 𝑃𝑀𝐶 𝐾𝑒𝑟𝑜𝑠𝑒𝑛𝑒 ), the respective values were 11.7%, 20.4% and 41.6% and 55.3%, 62.6% and 66.6%. Among all the tested cookstoves, 𝐶𝑆 𝑃𝑀𝐶 𝐿𝑃𝐺 achieved the lowest emission values (PM2.5: 20.6 𝜇𝑔/𝑚 3 ; PM10: 31.3 𝜇𝑔/𝑚 3 and CO: 1 ppm) which are lower than the prescribed WHO values (PM2.5: 25 𝜇𝑔/𝑚 3 ; PM10: 50 𝜇𝑔/𝑚 3 and CO: 6 ppm).
