The Complete Biogas Library

Biogas Generation: developments, problems, and tasks - an overview (163KB)
Methane is the main constituent of what is popularly known as biogas. A colourless, odourless, inflammable gas, it has been referred to as sewerage gas, klar gas, marsh gas, refuse-derived fuel (RDF), sludge gas, will-o'-the-wisp of marsh lands, fool's fire, gobar gas (cow dung gas), bioenergy, and "fuel of the future." This paper gives an introduction to the fundementals of biogas production including the microbiology of anaerobic digestion and basic operational considerations (23 pages).

FAO Biogas Training Manual (3.32MB)
The rate of installation of family size biogas plants in Nepal has shown unprecedented growth in the past.
More people are getting involved in biogas as users, technicians, extension workers, researchers, trainers, supervisors and investors. As a result,
the need for suitable training programmes along with the development of a high quality training manual has become a matter of immense importance for the sustainable growth of the biogas sector in Nepal. One of the main components of the FAO funded support for the Development of National Biogas Programme Project has been the development of an appropriate training curriculum and materials with the objectives: (i) to create awareness on the biogas programme; and (ii) to provide background for the promotion and facilitation of biogas extension activities (202 pages).

Upgrading Biogas (1.07MB)   Biogas Upgrading and Utilisation (IEA Bioenergy, 20 pages). For many applications the quality of biogas
has to be improved. The main parameters that may require removal in an upgrading systems are H2S, water, CO2 and halogenated compounds:
      • Desulphurisation to prevent corrosion and avoid toxic H2S concentrations.
      • Removal of water because of potential accumulation of condensate in the gas line and the formation of a corrosive acidic solution.
      • Removal of CO2 will be required if the biogas needs to be upgraded to natural gas standards or vehicle fuel use.
      • Landfill gas often contains significant amounts of halogenated compounds which need to be removed prior to use.

Scaling Up Biomass Gasifier Use (498KB)

This report aims to highlight the various applications and contexts in which biomass gasification may be successfully utilized at a large scale. It also discusses the various dimensions that need to be considered in scaling up deployment in any of these categories, and suggests possible approaches that might be particularly promising. The analysis in this report builds on the experience and lessons from the substantial efforts in India on biomass gasifier development and dissemination over the last two decades. It also explicitly takes a systems perspective in analyzing the Indian case as well as possible ways forward in order to mainstream gasifier use in developing countries (126 pages).
