Feasibility study of a large scale biogas plant in Lagos, Nigeria
Tomori, Opeoluwa (2012) Feasibility study of a large scale biogas plant in Lagos, Nigeria. Masters by Coursework thesis, Murdoch University.
Lagos state hosts one of the largest emerging cities in the world, with such a status comes the problem of a population that is fast outgrowing the infrastructure required for its survival, such as sewage treatment facilities to prevent pollution. In a situation where the government is finding it difficult to solve problems the private sector must intervene where possible, but for this to happen they must see an avenue for profit making. In doing this research work I intend to investigate the possibility of turning the state’s sewage waste to energy for profit making such that private entities have an incentive to solve this problem.
This study includes a detailed study of the technology of a biogas plant, the process of digestion and a look at a number of other biogas plants operating around the world. The costs per cubic meter of gas produced were examined and were used to estimate a possible cost of such a plant in Lagos. The net present cost of such a plant was calculated, and a case study was used to compare the use of biogas with natural gas for industrial heat processes. The feasibility of the plant was explained and a sensitivity analysis of the effects of changes in capital cost and the discounting rate was done.
The NPC of the plant over its 10 year lifetime is $1.75million and it has a Levelised cost of $0.78/m3. The plant at current operation parameters is not viable because the net present value is negative.
To conclude the plant is not viable but with some changes in the regulatory environment, improvements in plant operations and extra efforts in sourcing revenue it has the potential to solve a major problem and also generate a good profit.
