  • Techno-Economic Feasibility of Hybrid Solar Photovoltaic and Battery Energy Storage Power System for a Soshanguve Mobile Cellular Base Station in South Africa
    2018
    Co-Authors: Banjo A. Aderemi, S. P. Daniel Chowdhury, Thomas O. Olwal, Adnan M. Abu-mahfouz
    Abstract:

    Over the years, sustainability, impact on the environment, as well as the operation expenditure have been a major concern to the deployment of mobile cellular base stations worldwide. This is because the mobile cellular base stations are known to consume a high percentage of power within the mobile cellular network. Such energy consumption contributes to the emission of Greenhouse Gases (GHG) through the use of conventional diesel generating a set. As a result, the mobile cellular operators are faced with the dilemma of minimising the power consumption, GHG emission, and the operation cost, while improving the Quality of Service of the networks. In attempting to find a solution, this study presents the feasibility and simulation of a solar photovoltaic (PV) with battery hybrid power system (HPS) as a predominant source of power for a specific mobile cellular base station site situated in Soshanguve area of the city of Pretoria, South Africa. It also presents the technical development, showed the Environmental Advantage and cost benefits of using a solar PV-battery HPS to power a base station site of a 24 hrs daily load of 241.10 kWh/d and the peak load of 20.31 kW as compared to using the HPS of solar PV-diesel generating set-battery. The solar resource pattern for the city of Pretoria was collected from The National Aeronautics and Space Administration and modelled statistically. Thus, the statistical modelling done using solar radiation resource exposure characteristic patterns of Pretoria, South Africa, revealed an average annual daily solar radiation of 5.4645 Wh/m2/d and 0.605 clearness index. The simulation and the design were done using the Hybrid Optimization Model for Electric Renewables and Matlab/Simulink software. The simulation finding shows that the HPS of solar PV-battery combination has about 59.62 % saving on Net Present Cost, Levelized Cost of Energy, and 80.87% saving on Operating cost as against conventional BS powered with Gen Set-Battery.

  • Is There a Generic Environmental Advantage for Starch–PVOH Biopolymers Over Petrochemical Polymers?
    Journal of Polymers and the Environment, 2012
    Co-Authors: Miao Guo, Richard J. Murphy
    Abstract:

    The current study was undertaken to address the general question of whether there is an Environmental Advantage for renewable, starch–polyvinyl alcohol (PVOH) biopolymer blends over petrochemical polymers. This was addressed using life cycle assessment (LCA) over a set of multiple case studies based on a consistent set of parameters and methodological background. A group of starch–PVOH blended biopolymers derived from different feedstocks (wheat, potato, maize) were compared with high density polyethylene (HDPE), low density polyethylene (LDPE) and expanded polystyrene (EPS) in a range of applications. The results suggest that a general Environmental Advantage does not exist for the starch–PVOH blended biopolymers over their petrochemical counterparts in all applications and, instead, a case-by-case approach is necessary to evaluate Environmental pros and cons, based on specific comparisons. Overall, starch–PVOH biopolymers were found to offer Environmentally superior options to LDPE in thermal packaging applications. However, this was not the case in other applications, where the outcome of comparisons between starch–PVOH biopolymers and HDPE/EPS varied according to various factors, including the specific end-of-life scenarios and the recycled content of the petrochemical polymers. A hierarchy of critical parameters for LCA-based decision-making concerning starch–PVOH biopolymers is suggested as a general outcome of this research.
