Moses Oluwatobi Fajobi, an esteemed researcher with a Ph.D. from University of Ilorin, Nigeria is a leading personality in Bioenergy Production, Biomass Characterization, Renewable Energy Studies, Energy Security, and Climate Resilience. His extensive body of work, which spans several crucial aspects of Renewable Energy Studies and Sufficient Energy Sustainability, plays a pivotal role in shaping and providing insights into nature-given raw materials in abundance and adequate bioenergy technological practices not just in Nigeria but also in broader global contexts. Through a series of impactful studies, Fajobi has provided deep insights into the energy crisis, health implications, and environmental challenges confronting energy sector in developing economies, particularly in Nigeria.

For instance, his 2022 publication by Springers in Scientific Reports Journal, investigated the Physicochemical Characteristics of Selected Lignocellulose Biomass in Nigeria, making a significant contribution to renewable energy studies. The paper characterized three typical agricultural residues of Nigerian origin namely; cow dung, mango pulp, and Chromolaena odorata leaves, with a view to establishing their potentials for biogas production. The study articulated the selected residues for proximate, ultimate, and compositional analyses which are key to certifying the viability of any residue for anaerobic digestion. By providing these comprehensive analyses, Fajobi’s research offers invaluable insights for residue valorization in the Nigerian context. The study’s implications are profound, offering documented guidance for biomass characterizations aimed at valorization, viability of biomass, raw material availability, reducing environmental pollution, containment of adverse health challenges, and enhancing the resilience of local economies and climate change.

Additionally, Fajobi’s 2022 review on the Effect of Biomass Co-Digestion and Application of Artificial Intelligence in Biogas Production as featured in the Journal of Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, is another giant stride that underscores the urgent need for alternative energy and incorporation of artificial intelligence in bioenergy production. This research is of paramount importance to Nigeria, which is particularly vulnerable to epileptic energy supply, and overdependence on fossil fuels. The state-of-the-art review of various biomass used as feedstock in anaerobic digestion was presented by the study. It also reviewed the efficacies of existing biomass and experimental formulations used in biogas production putting in mind the influence of co-digestion of biomass on percentage methane yield. Modeling of the anaerobic digestion process using various commercially available artificial intelligence packages was also critically reviewed with peculiarity to their limitations and computational abilities. Furthermore, it also examined the adaptability, governing equations, processing time, flexibility, and applicability of artificial intelligence in anaerobic digestion process.

Therefore, the study established that artificial intelligence modeling has the potential to drastically reduce the process development time for anaerobic digestion of biomass, although at varying degrees. Some of the machine learning packages reviewed and found to be suitable for smart bioenergy production include; Artificial Neural Network, Fuzzy-Logic, Fuzzy Inference System, Support Vector Machine, Design Expert, Minitab, Adaptive Neuro-Fuzzy Inference System. Revolution is urgently needed in the area of sustainable energy supply because fossil fuels are gradually becoming limited in quantity. In this connection, Fajobi calls for a cohesive global and local response that includes adopting co-digestion of biomass to enhance bioenergy production rich in methane contents, and smart (Artificial intelligence) energy production approaches which gives room to remotely monitor the anaerobic digestion process, better waste management, adequate waste-to-wealth orientation, and production of ecofriendly fuels to stabilize climate hitches.

The energy crisis emanating from the rapid increase in global energy demand, instability observed in the global fossil fuel marketing, continued greenhouse gas emissions to the atmosphere and environment, and extinction of fossil fuels is an emerging but unpalatable global phenomenon. These factors informed the need for active heterogeneous exploration of available renewable energy resources to salvage the situation. In his continued efforts, Fajobi published groundbreaking research on Safety assessment of charcoal usage and effects of common charcoal ignition aiders on combustion in 2022, featured in the Scientific Reports Journal published by the Springers. The cost of procurement of other viable energy resources and poverty level are major identifiable factors that brought the use of Charcoal to the lime light. Common ignition aiders in the study area are paper, nylon, rubber, plastics, petrol, the residue of processed palm oil (locally known as Oguso in South-Western Nigeria), maize cob, wood, and kerosene. The various ignition aiders have varying degrees of emissions attributions mostly harmful to the ecosystem upon inhalation.

This study experimentally investigated the combustion indices of the ignition aiders including the carbon monoxide and volatile organic compound, VOC. The combustion index of paper has the least value of carbon monoxide (CO) 28.1 ppm, but with a 3434.54 ppm VOC value. Therefore, it is recommended for use. The average energy content reported for oak trees, afara, obeche, mahogany, and iroko woods is 32,149 kJ/kg compared to others that are lesser. It is concluded that this value is excellent. By advocating the alternative energy adoption, Fajobi proposes transformative solutions that can drastically improve the efficiency and sustainability of energy mix across Nigeria. These innovations are pivotal for reducing wastes, improving health system and enhance the climate formulation, alleviating poverty, and guarantee energy availability, thereby supporting broader economic stability and growth.

Furthermore, in 2023, Fajobi published his findings on Prediction of Biogas Yield from Co-digestion of Lignocellulosic Biomass Using Adaptive Neuro-Fuzzy Inference System (ANFIS) Model in Journal of Engineering. The developed model provided a novel approach critical to domesticating bioenergy innovation and ease biomass anaerobic digestion as regarding the optimal process/operational parameters for biogas yield. This study developed an ANFIS model for efficient and accurate prediction of biogas yield from cow dung co-digested with mango pulp and Chromolaena odorata. It is important to emphasize that the model can be adapted for any other forms of biomass. Meanwhile, as population of Nigeria increases, and proportionate biomass are generated abundantly, integrating sustainable predictive model for adequate biogas yield is expedient, therefore, the study adapted the developed model into a graphical user interface for seamless biogas yield prediction. Biogas producers and allied will find, in this model, an adequate working tool for the optimization of biogas yield. This innovation is capable to enhance process monitoring and performance, reduce waste around, guarantee energy availability, create green jobs, and promotes sustainable urban living.

Moreover, Dr. Moses Oluwatobi Fajobi is a mentor and educator, who actively contributes to building the capacity of the next generation of Mechanical Engineers, renewable energy researchers and policy-makers. By teaching and supervising research projects at Ladoke Akintola University of Technology, he ensures that young scholars are equipped with the knowledge and skills necessary to address the challenges facing energy sector in Nigeria and beyond.

Summarily, Moses Oluwatobi Fajobi’s scholarly work is a beacon of knowledge and innovation in the realms of Mechanical Engineering, Renewable Energy Studies, Users’ Safety and Climate Resilience. His research not only advances academic understanding but also serves as a crucial guide for practical actions and policy development aimed at improving the livelihoods of Nigerians and enhancing the sustainability of energy production. As his research continues to influence and inspire, Fajobi remains a cornerstone in the global dialogue on sustainable renewable energy production, ensuring that his contributions will resonate well into the future and continue to foster significant positive changes in the energy sector and beyond.
