This book reviews the nature of biogas promotion strategies as well as biogas digester designs widely disseminated in Ghana and other countries. It looks into challenges facing the design, construction, and operation of biogas plants in Ghana based on a field survey of 50 biogas installations, and interviews with both end-users and service providers. From the survey, sanitation was found to be the main motivational reason for people using biogas plants. Only 22 of the surveyed installations were functioning satisfactorily. Reasons for non-functioning include non-availability of dung, breakdown of balloon gasholders, absence of maintenance services, lack of operational knowledge, gas leakages, and bad odour in toilet chambers of biolatrines. Design problems observed involved the wrong orientation of inlet pipes of biolatrine digesters and the faulty interconnection between tandem digesters. This book recommends the development of a national programme focussing on three major areas sanitation, energy, and organic fertilizer production. It further advocates for the promotion of standardized digesters for large scale promotion in Ghana.
The United Nations Environment Programme (UNEP) in collaboration with the German International Development (GIZ) is implementing a project entitled "Operationalizing Green Economy (GE) Transition in Africa" in five selected countries: Ghana, Ethiopia, Kenya, Mozambique and Rwanda. As part of the GE project implementation activities in Ghana, this baseline survey was conducted in the three selected planning units in Ghana namely, Tolon District (Agriculture Sector), Kumasi Metropolitan Assembly (Energy Sector) and Tema Metropolitan Assembly (Waste Sector). The proposed GE options for the Kumasi Metropolitan Assembly (KMA) are (1) Generation of energy from biomass waste such as pellets, briquettes and biogas from organic waste (2) Utilization of energy efficient cook stoves such as Eco-stove at institutional, commercial and household level. Current quantity of biomass waste converted into pellets and briquettes are: Abellon - 25,000 MT per year, Esereso Carbon Products - 4,000MT/year) and Sustainable Energy Solutions - 100 MT of wood off cuts into 30MT of kindling wood sticks per month.
In this study, a solar PV-biogas hybrid power system for electrification is designed for Mankramso community located in the Offinso-North district in Ghana. The daily electric load demand in Mankramso community was estimated at 262.05 kWh/d, for 400 households, school, health clinic, commercial loads (flour mills, cold store, and small businesses), church buildings and streetlights. Hybrid Optimization Model for Electric Renewable (HOMER) software was used to perform technical, economic and greenhouse gas emission analysis of the hybrid power system. The findings show that the system configuration which comprises of 18.6 kW of PV panels, 45 kW of biogas generator, 62 kWh of battery storage and 15.7 kW of converter is the most optimal hybrid power system configuration to meet the daily electric load. This optimal hybrid power system had a levilized cost of energy (LCOE) of US$ 0.188/kWh with an initial capital cost of US$ 102,247. This LCOE is only 10.6% higher than current LCOE (US$ 0.17/kWh) for residential tariffs in Ghana at the time of this study.
