    Climate change mitigation with carbon capture: an overview
    (2023) Towoju, O. A.; Petinrin, M. O.
    The world is at the verge of catastrophe occasioned by the effect of climate change. Drastic action needs to be taken to reverse this ugly trend. Some of the proffered solutions to global warming is the adoption of renewable energy usage and a stop of fossil fuels combustion. However, the low capacity factor and energy return has been the bane on the usage of some renewable energy sources. A leeway however, exists in the technology of removal of greenhouse gases referred to as Carbon Capture. The widely adopted method being at point source because of its high concentration favouring easier processes of removal. This technology has received increased attention over the years as evident from data for the past five years. However, this technology alone cannot guarantee atmospheric CO2 levels required to maintain global temperature rise below the 1.50C mark. Negative emission technology processes of which the Direct Air Capture (DAC) is one needs to be developed. The infancy of the DAC technology and the uncertainties that surrounds its cost still pose as challenges. The cost of removing a tonne of CO2 with DAC technology can be as high as $600, this is unsustainable and has to be drastically reduced. While it is projected that DAC technology can take out 980 Metric Tonne (MT) CO2/annum by 2050, current figures stand at 0.008 MT. It is our view that the development of solid adsorbents and the harnessing of the thermal energy inherent in the sun can be a game changer.

    Optimal distributed generation location and sizing for loss minimization and voltage profile optimization using ant colony algorithm
    (2021-02) Ogunsina, A. A.; Petinrin, M. O.; Petinrin, O. O.; Offornedo, E. N.; Petinrin, J. O.; Asaolu, G. O.
    A system of power generation whereby the generating equipment is located close to the point of usage, thereby reducing losses and operation cost is called distributed generation (DG). However, it is imperative that DGs are sited such that the quality of power delivered is optimized and the total real power loss within the system minimized. This paper proposes an approach for optimum sizing and siting of DGs sizing in a power distribution system using Ant Colony Optimization (ACO) algorithm. To validate the algorithm the IEEE 30 bus standard test system was employed. A 92% decrease in real power loss within the system relative to the value before the connection of DGs was observed, while the minimum bus voltage increased from 0.656 per unit to 0.965 per unit. The results obtained from ACO are further verified by creating an ETAP model of the IEEE 30 bus system and simulating the impact of DG on the system. A significant reduction in total real power losses within the system and improvement in voltage profile was observed when the DGs are placed at the ACO derived sites relative to at other locations. Therefore, Ant Colony Algorithm can be used in deriving the optimum sites and sizes of DGs in a power distribution system.

    Microgrids: a decentralized alternative for rural electrification in Nigeria
    (2020) Petinrin, J. O.; Petinrin, M. O.; Johnson, D. O.
    Poor electricity services remain a major obstacle to growth in Nigeria, as inadequate and epileptic power supply undermines investment opportunity, economic growth, social and infrastructure developments. Centralized power generation, transmission and distribution system operations in Nigeria can no longer deliver competitively cheap and reliable electricity to remote customers on and off the national grid. Anticipated development in generation with a balanced combination of ongrid and off-grid power projects is very achievable in Nigeria. A balanced approach could potentially lead to an accelerated journey to full electrification in the country. This would in turn result in a significant boost of the country’s economy, as power has been proven to be an enabler of other sectors of the economy. This paper presents micro grids as a decentralized alternative for rural electrification in Nigeria. The paper reviews the electrification status in Nigeria, power management of micro grid and prospect of renewable energy for rural energy provision. The benefits, challenges and future prospects of micro grid are also discussed. Implementation of decentralized micro grid across 774 local governments of Nigeria with five (5) micro grids installed in each local government will not only improve the wellbeing of Nigerian rural dwellers, but also enhance Nigeria's energy and economic prospects for potential global investment.
