This paper deals with an experimental investigation to improve the hydrogen production by water photoelectrolysis. An experimental facility was built: it is mainly constituted by a solar simulator, the photoelectrolytic cell, the electric power supply system and a recirculating and gas sampling...

Solar reflectance of buildings’ envelope and urban paving represents an important optic-energetic property for the characterization of building energy performance for cooling and to reduce the urban heat island effect. Together with the emissivity, it represents the main feature contributing...

Gas hydrates have a large capacity for the storage of gases and are an attractive method for gas filtration and transportation. However, hydrate formation is usually controlled by the rate of crystallization and thus it can be a slow process. A technology that will rapidly and continuously form...

Recent research developments focused on Climate Change issue aimed at achieving Kyoto targets. In this context, an innovative methodology (officially recognized by WEC in 2009) is proposed to mitigate Global Warming by artificially enhancing earth’s Albedo. Such a methodology allows to...

The optimization of optical properties of buildings’ envelope and urban paving represents an important research field for reducing the urban heat island effect. The overheating of a surface exposed to sunlight can be reduced by improving solar reflectance. In this sense, several studies have...
