Fuel cell or hydrogen systems offer the potential for clean, reliable and on-site energy generation. This article review current literature with the objective of identifying the latest development in membrane and bipolar plates for the conventional fuel cell and unitized regenerative fuel cell...

One of the most important methods of saving energy in a building is by carefully designing its facade. A 'double skin façade' is optimally one of the best options in managing the interaction between the outdoors and the internal spaces. It also provides some architectural flexibility to the...

Brackish water are any water sources with TDS between 1000 and 15 000 mg/L. Brackish water cannot be consumed by us directly due to its high salinity. According to World Health Organization (WHO), water with salinity below 500 mg/L is acceptable as drinking water. There are quite a...

Researches on activated carbon fiber (ACF) in adsorption cooling system are important. ACF as adsorbent offers solution to shortcomings in solar adsorption refrigeration technology. By having ACF, rapid adsorption/desorption time and higher adsorption capacity per unit mass of adsorbent can be...

Renewable resources gained more attention in the last two decades due to persisting energy demand coupled with decrease in fossil fuel resources and its environmental effect to the earth. In Iraq, the electric power generated is not enough to meet the power demand of domestic and industrial...

This paper is about predicting the average conventional energy conversion by a photovoltaic system in Malaysia. The calculation is based on average number of days in a month. Average hourly energy flows are estimated based on knowledge of array test parameters, monthly average of hourly ambient...

A conceptual design and performance of a dual-purpose solar continuous adsorption system for domestic refrigeration and water heating is described. Malaysian activated carbon and methanol are used as the adsorbent–adsorbate pair. The heat rejected by the adsorber beds and condensers during the...

Wind data collected at ten stations in Malaysia were analysed for wind energy potential. The data were collected over a ten-year period (1982–1991). The results were presented as a Weibull distribution and analysis indicated that the station at Mersing has the greatest potential, with a mean...

Based on the fact that PV systems are clean, environment friendly and secure energy sources, PV system installation has played an important role worldwide. However, the drawback of PV system is the high capital cost as compared to conventional energy sources. Currently, many research works are...

Global warming, depletion of natural resources, acid rains, air and water pollutions, and ozone depletions are some of the environmental consequences that are deemed attributable to human activities on planet earth. Sustainable practices have been therefore evolved as main remedies to tackles...
