In developing countries traditional biomass such as fuel wood, plant residues and dung are still the main source of household energy. Increasing wood consumption for cooking is resulting in deforestation creating severe ecological, economical and social problems. Moreover, open fire cooking is frequently practised in poorly ventilated rooms, which leads to serious health hazards. To solve those problems, locally produces plant oil could be a promising household fuel for rural areas in developing countries. Therefore, objective of this research was to develop a household stove that can be fuelled with plant oil. A project was implemented in a Public Private Partnership between the University of Hohenheim and Bosch-Siemens-Haushaltsgeräte GmbH. Different plant oils have been tested with a newly developed plant oil pressure stove and a comparative study with conventional stove types was performed. The experiments have shown that plant oils with low content of unsaturated fatty acids and low phosphorous content are preferable. Carbon monoxide emissions of the plant oil stove have proven to be considerably lower compared to conventional stoves. Fuel costs were in the range of kerosene and LPG stoves and only lower for wood fires. However, the investment costs are still high. Mass production would lower the costs but in addition further development has to focus on cost reduction.
