Abstract | Ghana is a country faced with pressing developmental challenges on energy, sanitation, environment and agriculture. The development of a large scale, enterprise-based biogas programme in Ghana will improve sanitation, produce clean energy, reduce greenhouse gas emissions, promote nutrient recovery, and create jobs. While aforementioned benefits of biogas are known, the biogas industry is still not growing at rates that would enable its impact on sanitation, agriculture and energy usage to be felt, owing to challenges such as low awareness creation and poor biogas supply chain, lack of well-trained personnel, poor follow-up services, and high cost of biogas digesters – USD 235- 446 per cubic meter. This paper looks at the chronology of biogas developmental in Ghana, technical and market potential of household biogas plants, strengths and weaknesses of main biogas service providers, human resource development, quality issues, and risks involved in developing a large scale household biogas programme. From the paper, the technical and market potential of dung-based, household biogas digesters in Ghana are estimated at 162,066 and 16,207 units respectively. In order to take full advantage of biogas technology, the paper recommends the development of standardized digesters, increase in awareness programmes on the lifelong benefits of biogas systems, introduction of flexible payment schemes, and stepping-up of follow-up services. Finally, there is an urgent need for a ‘promoter’ who will engage all stakeholders to ensure that a national action plan on biogas technology is initiated and implemented. |
