|Title: ||The potential for bottled biogas for clean cooking in Africa|
|Authors: ||Kemausuor, Francis|
|Issue Date: ||Jun-2021|
|Abstract: ||This paper is the outcome of an initial scoping study on the potential for bottled biogas as a clean cooking option
for Ghana and Uganda. The study seeks to understand the opportunities for bottled biogas for cooking in Africa,
and asks why it has not already taken off, and the key issues to be addressed to enable this.
The paper starts by outlining the nature of the multiple challenges being addressed in the pursuit of clean and
modern solutions for cooking, including the health impacts from combustion of solid biomass fuels but also the
emissions of GreenHouse Gases. In parallel, developing regions face issues in managing residues and wastes
from agro-industry and small-scale farming. Using residues to produce biogas for cooking has a long history in
Asia, including at micro scales, typically in household-scale bio-digestors. Biogas is also seen as a bioenergy
opportunity for Africa, but many millions of families live in peri-urban areas or for other reasons have insufficient
bio-resources to fuel their own digestor.
Bottling of biogas has been suggested as on option for providing accessible, renewable, clean energy to
individual households. Research and some pre-commercial trials have taken place in India and parts of Africa,
but there is limited evidence in the public domain, and it is evident that bottling has not yet taken off at scale.
This study sought to understand the opportunities and the barriers to implementation of bottled biogas for
cooking in Africa, with a focus on Ghana and Uganda.
Section 2 of the report reviews anaerobic digestion and biogas production and highlights the technical issues
which must be overcome to achieve a bottled biogas product. The current status and potential opportunities for
biogas production are reviewed for Ghana (Section 3) and Uganda (Section 4) along with country specific policy
support mechanisms. Section 5 reports on field visits to biogas producing sites in Ghana and Uganda in August
2019. Section 6 gives an outline of a workshop and conference organised under this study in October 2019.
Section 7 provides overall conclusions of this scoping study and suggests next steps|
