An environmentally friendly phase change material (PCM) was successfully prepared by encapsulating natural soy wax into polyurethane (PU) nanofibers using coaxial electrospinning technique. The morphology and the structure of the wax/PU composites were characterized. Thermal behaviors as well as...

Ultrafine phase change fibers based on polyethylene glycol (PEG)/cellulose acetate (CA) blends in which PEG acts as a model phase change material (PCM) and CA acts as a supporting material, were successfully prepared via electrospinning. The effect of PEG content on the morphology, crystalline...

Shape-stabilized composite phase change materials (ss-CPCMs) composed of PEG (polyethylene glycol) and MCS (mesoporous calcium silicate) were prepared by a facile blending and impregnating method. Various techniques were employed to characterize their structural and thermal properties. The...

Shale inhibition, low-temperature performance, the ability to prevent calcium and magnesium-ion pollution, and hydrate inhibition of polyethylene glycol drilling fluid were each tested with conventional drilling-fluid test equipment and an experimental gas-hydrate integrated simulation system...

A gel polymer electrolyte containing I−/I3− redox couple was prepared using polyethylene glycol (PEG) as polymer matrix and propylene carbonate (PC) as organic solvent by sol–gel method. A dye sensitized solar cell (DSSC) employing the gel polymer electrolyte gives an open-circuit voltage...

Thermal Energy Storage (TES) and Demand Response (DR) offer unique benefits to reducing the electricity consumption, carbon emission, investment, and operational cost of generating cooling energy by bridging the gap between cooling energy demand and production. To provide comprehensive guidance...

A flexible coupling of power and heat sectors can contribute to both renewable energy integration and decarbonization. We present a literature review of model-based analyses in this field, focusing on residential heating. We compare geographical and temporal research scopes and identify...

As the share of intermittent renewable electricity generation increases, the remaining fleet of conventionalpower plants will have to operate with higher flexibility. One of the methods to increase power plantflexibility is to integrate a thermal energy storage (TES) into the water-steam cycle...

The reversible exothermic reaction of CaO with water is considered one of the most promising reactions for high temperature thermal energy storage. In this paper, a novel technical design of a MW-scale thermochemical energy storage reactor for this reaction is presented. The aim is to provide an...
