The excessive usage of fossil fuels has world-widely caused chain environmental consequences. An interesting solution to this problem is the systematic exploitation of available renewable energy sources, including solar energy. Greece is located in a major geographical region with an abundant...

This review analyses the growth in small ‘low power’ renewable energy and consumer product technologies and their potential utility in rural and remote economic development. The historical legacy of increasingly industrial-scale and expensive centralised high voltage alternating current (AC)...

The paper presents a summary of the performance results obtained from a 2-year monitoring period of the first standalone photovoltaic (PV) system in Malta. The sizing, construction, monitoring and detailed analysis of data are described elsewhere [3, 4, 71. Following these results, a cost...

This research compares two generation components in grid-connected and stand-alone power supply (SPS) systems (6 kWp solar photovoltaic array, and a 6 kWp diesel generator), separately supplying a homestead’s electricity load (12 kWh day−1 average, 10 kWp), against a 2 km underground...

The evolution of microstructures of yttria-doped ceria (YDC) upon the heating at 500 °C in a reducing atmosphere has been characterized. Even though obvious cracks will not appear at such a low temperature, local microstructures will change in terms of superstructure formation. Electron...

A state-space dynamic model for a palm wastes boiler is being developed and simulated. The unique feature of this boiler is that it uses wastes in the form of fiber and shell from the palm oil processing as its fuels. Specific characteristics of oil palm waste boilers are non-uniform fuel feed,...

This article deals with a PEMFC (proton exchange membrane fuel cell) electrical model based on a 1D analog representation of mass transport phenomena, and taking into account the influence of gas supply conditions on fuel cell voltage. By using an electrical analogy to describe transport of...
