This paper presents an original life cycle assessment (LCA) of a concentrating solar power (CSP) plant with thermochemical energy storage (TCES). The studied CSP plant is a hypothetic solar tower plant with a Rankine power cycle, and the TCES material used is calcium hydroxide. Based on three proposed TCES integration concepts, detailed sizing and ...

With the concentration of CO2 in the atmosphere increasing beyond sustainable limits, much research is currently focused on developing solutions to mitigate this problem. Possible strategies involve sequestering the emitted CO2 for long-term storage deep underground, and conversion of CO2 into value-added products. Conventional processes for each o...

In the leather industry, considerable amounts of non-recyclable solid leather wastes (SLWs) are produced and accumulated in factories. In this work, the non-isothermal thermochemical analysis (TGA) test was used to analyse the thermal degradation behaviour of chromium-tanned leather shaving, which is one of the main SLWs. The pyrolysis experiments ...

The present paper examines the failure mechanism of the coating system of Al2O3–ZrO2·5CaO applied on a Cast iron substrate. The atmospheric plasma spray coating technique was used for coating. A muffle furnace was used to heat the sample to 600 ± 2 °C followed by ambient cooling. Both the heating and cooling cycles were maintained for 30 min. Resul...

The energy situation in tropical insular regions, as is found in French Polynesia, presents a number of challenges, including heavy dependence on imported fuel, high transport costs from the mainland and weak electricity grids. By contrast, these regions possess a variety of renewable energy resources, which are favorable for the exploitation of sm...
Perennial grasses are herbaceous, lignocellulosic plants. Their chemical composition is made up primarily of structural polysaccharides, namely, celluloses and hemicelluloses, of lignin, and of small fractions of nonstructural components, such as extractives, protein, lipids, pectin, and ash. The recalcitrance of lignocellulosic material has been r...
Solar thermal energy, especially concentrated solar power (CSP), represents an increasingly attractive renewable energy source. However, one of the key factors that determine the development of this technology is the integration of efficient and cost effective thermal energy storage (TES) systems, so as to overcome CSP's intermittent character and ...

Chlorinated paraffins (CPs) generally function as flame retardants and plasticizers in various materials. They are most likely to be processed by thermal processes during the entire life cycle. However, data on the formation and emission of CPs during thermal processes are still not fully understood. In this study, we simulated industrial thermal p...
