A new hybrid system mainly consists of a molten carbonate fuel cell (MCFC) and a Stirling heat engine is established, where the Stirling heat engine is driven by the high-quality waste heat generated in the MCFC. Based on the electrochemistry and non-equilibrium thermodynamics, analytical...

In this paper, a biogas fuelled hybrid system, obtained by integrating a molten carbonate fuel cell with a micro-turbine is considered. The size of the plant is selected on the basis of the maximum biogas production registered by monitoring the annual operation of an anaerobic digestion plant....

In this paper, a biogas fuelled energy system for combined production of electricity and hydrogen is considered. The system is based on a molten carbonate fuel cell stack integrated with a micro gas turbine. Hydrogen is produced by a pressure swing absorption system. A multi-objective...

The electrode stability is a key issue for the development of conventional hydrogen fuelled and direct internal reforming (DIR) molten carbonate fuel cells (MCFCs). While for conventional MCFC anodes the stability problem has been addressed by the addition of Al or Cr to Ni, the problems of the...

Current research into the pattern of energy usage in South Africa reveals an extraordinarily heavy reliance on coal-fired electricity, a strategy that is not only unsustainable but which has resulted in serious air pollution problems. The paper argues that this development ought to be seen in...

Renewable power technologies are inherently capital-intensive, often (but not always) with relatively high construction costs and low operating costs. For this reason, renewable power technologies are typically more sensitive to the availability and cost of financing than are natural gas power...

Approximately 136,000 refuse trucks were in operation in the United States in 2007. These trucks burn approximately 1.2 billion gallons of diesel fuel a year, releasing almost 27 billion pounds of greenhouse gases. In addition to contributing to global climate change, diesel-fueled refuse trucks...

Landfill gas (LFG) projects use the gas created from decomposing waste, which is approximately 49% methane, and substitute it for natural gas in engines, boilers, turbines, and other technologies to produce energy or heat. The projects are beneficial in terms of increased safety at the landfill,...

Mexico, similarly to other developing countries, has planned landfilling as the central technology to manage municipal solid waste (MSW). In this research, the current and future situation of final disposal of MSW in Mexico was studied, focusing on the spatial and temporal evaluation of final...
