Abstract: | Crop residues are common in rural Ghana due to the predominant role agriculture plays in
livelihood activities in these communities. In this paper we investigate the prospects of exploiting
agricultural crop residues for rural development in Ghana through bioenergy schemes. A theoretical
energy potential of 623.84 PJ per year, which is equivalent to 19,781 MW was estimated using
crop production data from the Food and Agricultural Organization of the United Nations and
residue-to-product ratios. Ghana has a total installed generation capacity of 4577 MW which is four
times less the energy potential of crop residues in the country. Cocoa pod husks were identified as
important biomass resources for energy generation as they are currently wasted. To further assess
the energy potential of cocoa pod husks, different cocoa pod husks samples were collected across
the six cocoa growing regions in Ghana and thermo-chemically characterised using proximate and
ultimate analysis. The low levels of nitrogen and sulphur observed, together with the high heating
value, suggest that cocoa pod husks and for that matter crop residues are eco-friendly feedstock that
can be used to power rural communities in Ghana. |
