Energy poverty is a global threat to sustainable development and improved livelihoods hence the availability of clean, affordable, reliable and sustainable energy is a central issue to Kenya’s national development objectives. Biogas technology in Kenya has been earmarked as one of the main...

Multi-criteria evaluation methods are often used for sustainability assessment. One such method is the Multi-criteria Spider-gram Cumulative Surface Area (MCSA score) recently used for this purpose (Nzila et al., Multi-criteria sustainability assessment of biogas production in Kenya. Applied...

The nano-decoration of electrode with nanoparticles is one effective way to enhance power output of microbial fuel cells (MFCs). However, the amount of nanoparticles used for decoration has not been optimized yet, and how it affects the microbial community is still unknown. In this study,...

Fossil fuels are an integral part of the US energy portfolio, playing a prominent role for current and future domestic energy security. A sustainable, low-carbon future will require CO2 to be captured from major coal and natural gas power plants. However, fossil fuel electricity generation CO2...

A large number of research works were undertaken for the planning of sustainable electricity generation and CO2 mitigation (EGCM) infrastructure design under uncertainty. The typical methodologies assessed the performance of the problem under the variability of the uncertain parameters by...

In a power-generation system, power plants as major CO2 sources may be widely separated, so they must be connected into a comprehensive network to manage both electricity and CO2 simultaneously and efficiently. In this study, a scalable infrastructure model is developed for planning electricity...

This paper describes a novel resorption cycle driven by the low grade heat for the cogeneration of electricity and refrigeration, which is based on ammonia adsorption refrigeration technology. The presented cycle features a variable endothermic process which stands for higher adaptability if...

White-rot fungus is able to secrete laccase, which can reduce O2 to H2O and has been widely used in enzymatic fuel cells. In this work, a strain of white-rot fungus, Coriolus versicolor, is inoculated in the cathodic chamber of a microbial fuel cell (MFC) to improve cathode reduction efficiency...

The World Health Organisation estimates that over 20% of the global population (∼1.4 billion people) lack access to electricity. Furthermore, 40% of the global population (∼2.7 billion people) rely on the traditional use of biomass for cooking (WHO 2011, OEDC/IEA, 2010). This study details...

This project involves the development of a prototype electrical generator for delivering and storing small amounts of electricity. Power is generated using the thermoelectric effect. A single thermoelectric generator (TEG) is utilised to convert a small portion of the heat flowing through it to...
