Energy Mix

Household fuel refers to any material that is used to produce heat or power by burning. Some of the household fuel used in Nigeria includes: biomass, charcoal, kerosene, CNG (Compressed natural gas), LPG (liquefied petroleum gas), electricity. Biogas is relatively new and emerging as a viable option. In this study, biogas was produced using cow dung and the emission characterization of biogas and that of LPG was compared using a Gasboard model 5020H gas analyzer. Results of biogas emission is as follows; CO: 0.01%Vol , CO2: 0.14 %Vol, HC: 0010 ppm, NOx: 0002 ppm while LPG gives the following; CO: 0.30%Vol , CO2: 1.88 %Vol, HC: 0003 ppm, NOx: 0007 ppm. Recommendation was made for the inclusion of biogas in Nigeria energy mix because of its relatively better emission.

Abstract Concerns about environmental degradation and finite natural resources necessitate cleaner sources of energy for use in the transportation sector. In Canada, natural gas (NG) is currently being appraised as a potential alternative fuel for use in vehicles for both medium and heavy-duty use due to its relatively lower costs compared to that of conventional fuels. The idea of compressed natural gas vehicles (CNGVs) is being mooted as inexpensive for fleet owners and especially because it will potentially significantly reduce harmful emissions into the environment. A short feasibility study was conducted to ascertain the potential for reduced emissions and savings opportunities presented by CNGVs and renewable NGVs (RNGVs) in both medium and heavy-duty vehicles. The study which is discussed in the present paper was carried out on long-haul trucking and refuse trucks respectively. Emphasis was laid on individual vehicle operating economics and emissions reduction, and the identification of practical considerations for both the individual application and CNGVs/RNGVs as a whole. A financial analysis of the annual cost savings that is achievable when an individual diesel vehicle is replaced with a CNG vehicle was also presented. This paper drew substantial references from published case studies for relevant data on maintenance costs, fuel economy, range, and annual distance traveled. It relied on a summary report from Argonne National Laboratory's GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) [18] for its discussion on relative fuel efficiency penalties for heavy-duty CNGVs. The fuel cost figures were mostly drawn from motor fuel data of the Ontario Ministry of Transportation, since the Ministry is one of the few available sources of compressed natural gas fuel prices. Finally, the GHGenius life-cycle analysis tool [19] was employed to determine fuel-cycle emissions in Canada for comparison purposes. The study produced remarkable findings. Results showed that compared to diesel-fuelled vehicles, emissions in CNG heavy-and-medium-duty vehicles reduced by up to 8.7% (for well-to-wheels) and 11.5% (for pump-to-wheels) respectively. Overall, the most beneficial application appeared to be long-haul trucking based on the long distances covered and higher fuel economy achieved (derived from economies of scale), while refuse trucks appeared to have relatively marginal annual savings. However, these annual savings are actually a conservative estimate, which will ultimately be determined by a number of factors that are likely to be predisposed in favour of NG vehicles. Significantly, the prospect of using RNG as fuel was found to be a factor for improving the value proposition of refuse trucks in particular, certainly from an emissions standpoint with a reduction of up to 100%, but speculatively from operational savings as well.
