- Description: Abstract: Unstable prices, energy security, depleting reserves and their negative effect on the ecosystem have forced mankind to critically tackle it’s over dependence on fossil fuels. Fossil fuels are oil coal and natural gas which currently caters for over 80% of the world’s energy needs. Crude oil derivatives and coal have been extensively tapped and utilized to make living more comfortable and to drive different sectors that power the world’s economies. These have however come at an irreparable cost on human health and the environment. The transport sector, a major driver of development consumes the 2nd largest portion of our fossil energy reserves and has also been at the forefront of the creation of alternative fuels to mitigate various economic, political and environmental challenges associated with the refining and utilization of the conventional fuels in the sector which are petrol and diesel. The sector recently turned to natural gas as an efficient substitute particularly in the more popular passenger cars that utilize spark ignition engines. It performs excellently with lesser tail pipe emissions when compared with petrol which emits lesser harmful products than diesel. Though readily available, with well-developed infrastructure, its fossil nature makes it a finite resource hence the need for a viable renewable replacement fuel. Many alternative fuels have been developed to power the spark ignition engine as stricter emission standards are being created and the need for improved fuel economy with better system efficiency. This paper highlights the popular alternative fuels been utilized in spark ignition engines which are hydrogen, ethanol, liquefied petroleum gas and biogas looking at criteria such as performance, renewability, ease of integration into existing infrastructure and cost with the need to make a case for biogas as the right substitute for petrol in existing and future spark ignition engine applications.

Energy potential of food waste generated by a middle class neigbourhood in Nigeria through anaerobic digestion. 2nd International Engineering Conference (IEC 2017) Federal University of Technology, Minna, Nigeria.
- Description: Abstract: The paper assessed the energy potential of the food waste content of the municipal solid waste generated by an upper middle class neigbourhood in Abuja, Nigeria. The findings from this research should encourage the government and private institutions involved in energy generation to tow the path of developed nations and continental partners like South Africa and look towards biogas technologies as means towards ameliorating the challenges faced with fossil based fuels and effective solid waste management. From the quantification exercise the Estate has the capacity to generate about 90.23GJ of energy per year from the anaerobic digestion of the food waste generated by the occupants.

Comparative evaluation of the performance of a bi-fuel vehicle on biogas and natural gas. 2nd International Engineering Conference (IEC 2017) Federal University of Technology, Minna, Nigeria.
- Description: Abstract: This paper assesses the performance of a retrofitted bi-fuel passenger car running on enriched biogas and natural gas with a view to investigating the similarities between both fuels. A sweep test was conducted using a chassis dynamometer which simulated actual driving conditions showed that the vehicle recorded similar maximum power outputs at 55kW and 54kW for natural gas and biogas respectively while similar acceleration times from 0 to 100km/h were also recorded.
