Purpose The utilisation of renewable energy sources for generating electricity and potable water is one of the most sustainable approaches in the current scenario. Therefore, the current research aims to design and develop a novel co-generation system to address the electricity and potable water needs of rural areas. Design/methodology/approach The cogeneration system mainly consists of a solar parabolic dish concentrator (SPDC) system with a concentrated photo-voltaic module at the receiver for electricity generation. It is further integrated with a low-temperature thermal desalination (LTTD) system for generating potable water. Also, a novel corn cob filtration system is introduced for the pre-treatment to reduce the salt content in seawater before circulating it into the receiver of the SPDC system. The designed novel co-generation system has been numerically and experimentally tested to analyse the performance at Karaikal, U.T. of Puducherry, India. Findings Because of the pre-treatment with a corn cob, the scale formation in the pipes of the SPDC system is significantly reduced, which enhances the efficiency of the system. It is observed that the conductivity, pH and TDS of seawater are reduced significantly after the pre-treatment by the corncob filtration system. Also, the integrated system is capable of generating 6–8 litres of potable water per day. Originality/value The integration of the corncob filtration system reduced the scaling formation compared to the general circulation of water in the hoses. Also, the integrated SPDC and LTTD systems are comparatively economical to generate higher yields of clean water than solar stills.

Abstract Enhancing nocturnal productivity holds promise for boosting the effectiveness of solar desalination setups. Current research concentrates on an innovative strategy: the integration of paraffin wax and Jatropha biodiesel as a composite energy storage material (CESM) to amplify distilled water output during nighttime. The composite material, comprising Jatropha biodiesel and paraffin wax in a 1:1 ratio by weight, is meticulously examined for its impact on productivity, juxtaposed against a conventional solar still (CSS). Results reveal a substantial improvement in thermal conductivity with CESM, exhibiting a noteworthy 20.37%% surge compared to pure paraffin wax. Furthermore, a solar still with biodiesel and phase change material (SSBDPCM) is pitted against a CSS, with continuous monitoring of water and absorber temperatures alongside distillate production. The findings illustrate that SSBDPCM achieves a 16% upsurge in water temperature and a 10% elevation in absorber temperature compared to CSS. Impressively, SSBDPCM achieves a staggering 63% increase in distillate production, yielding 3.6 l/m2 and 3.4 l/m2, in sharp contrast to CSS, which only manages 2.2 l/m2 and 2.1 l/m2 over a two-day test period. Furthermore, a comprehensive cost analysis showcases the economic superiority of SSBDPCM over CSS. SSBDPCM demonstrates a compelling 29.2% reduction in cost per liter and a significant 25.9% decrease in the payback period in comparison to CSS. These compelling outcomes underscore the substantial potential of the SSBDPCM approach in delivering heightened efficiency and cost-effectiveness, paving the way for a promising advancement in solar stills.

Primary material supply is the heart of engineering and sciences. The depletion of natural resources and an increase in the human population by a billion in 13 to 15 years pose a critical concern regarding the sustainability of these materials; therefore, functionalizing renewable materials, such as nanocellulose, by possibly exploiting their properties for various practical applications, has been undertaken worldwide. Nanocellulose has emerged as a dominant green natural material with attractive and tailorable physicochemical properties, is renewable and sustainable, and shows biocompatibility and tunable surface properties. Nanocellulose is derived from cellulose, the most abundant polymer in nature with the remarkable properties of nanomaterials. This article provides a comprehensive overview of the methods used for nanocellulose preparation, structure–property and structure–property correlations, and the application of nanocellulose and its nanocomposite materials. This article differentiates the classification of nanocellulose, provides a brief account of the production methods that have been developed for isolating nanocellulose, highlights a range of unique properties of nanocellulose that have been extracted from different kinds of experiments and studies, and elaborates on nanocellulose potential applications in various areas. The present review is anticipated to provide the readers with the progress and knowledge related to nanocellulose. Pushing the boundaries of nanocellulose further into cutting-edge applications will be of particular interest in the future, especially as cost-effective commercial sources of nanocellulose continue to emerge.

Water is a vital component of human survival. Drinking water is scarce in several large provinces around the world. Only saline water, which may be demineralised and utilised for drinking, is available in this situation. For extended journeys, normal water is required in boats and submarines. Self–demineralised equipment is usually installed in vehicles, but it consumes more conventional gasoline and is, therefore, more expensive. To address this problem, solar still can be used, which has the primary aim of converting seawater into consumable desalinated water. In this work, a solar still with phase change material (PCM) – RT58 which have better thermo-physical properties has been incorporated and investigated for thermo-economic performance. It is observed from the results that the RT-58 PCM achieved a greater yield compared to conventional solar still (CSS) without any PCM as an energy storage material. The productivity of solar still with PCM is increased by 46% relative to CSS. Also, the economic analysis revealed that the solar still with PCM is more economically viable than CSS in terms of cost per litre production of freshwater and payback period.

Abstract The main objective of this study is to enhance the yield of single slope solar still by extending the operating time of solar still by utilizing composite heat storage materials in the solar still. In this regard, the effect of the composite heat energy storage material developed by the mixture of beach sand with paraffin wax is investigated. The experiments are carried out in solar still with composite heat storage material (SSCHSM), and results are compared with solar still with sensible heat storage material (SSSHSM), solar still with latent heat storage material (SSLHSM), and conventional solar still (CSS). The outcome of the two days’ results showed that the total yield of SSCHSM, SSLHSM, SSSHSM, and CSS are 2050, 1880, 1420, and 1250 mL/m2, respectively, on day 1 whereas on day 2 it is 2950, 2680, 2000, and 1820 mL/m2. The thermal analysis results indicated that the average thermal efficacy of SSCHSM, SSLHSM, SSSHSM, and CSS is 21.59%, 19.83%, 14.92%, and 13.16%, respectively, on day 1 and day 2 it is 27.42%, 24.94%, 18.59%, and 16.89%. The economic analysis revealed that the cost per liter and payback month of SSCHSM are $ 0.031 and 6.2 months, whereas the cost per liter for SSLHSM, SSSHSM, and CSS was $ 0.034, $ 0.044, and $ 0.048, respectively. Moreover, the payback period for SSLHSM, SSSHSM, and CSS was 6.8 months, 8.8 months, and 9.7 months, respectively.

Thermal Energy Storage (TES) is a valuable tool for improving the energy efficiency of renewable energy conversion systems. One of the most effective methods for harnessing thermal energy from solar sources is through energy storage using phase change materials (PCMs). However, the thermal performance of PCMs is hindered by their low thermal conductivity. This research focuses on enhancing the thermal performance of salt hydrate PCM using multi-walled carbon nanotubes (MWCNTs) and surfactants. Through experimental investigations, a salt hydrate PCM with varying concentrations of MWCNTs (ranging from 0.1% to 0.9%) was prepared using a two-step technique and their thermophysical properties were thoroughly characterized. Various techniques such as field emission scanning electron microscope, thermal conductivity analyzer, ultraviolet-visible spectrum, thermogravimetric analyzer, and Fourier transform infrared spectroscopy were utilized to study the effect of surfactant on the nanocomposites and examine their morphology, thermal conductivity, optical properties, thermal stability, and chemical stability. The results indicated that the inclusion of MWCNTs with salt hydrate significantly improved the thermal conductivity by 68.09% at a concentration of 0.7 wt %, compared to pure salt hydrate. However, this enhancement in thermal performance was accompanied by a reduction in optical transmittance in the developed nanocomposite PCM. Additionally, the formulated nanocomposite demonstrated excellent thermal and chemical stability up to temperatures as high as 468 °C. As a result, this nanocomposite shows great promise as a potential candidate for solar TES applications, offering favourable characteristics for efficient energy storage from solar sources.
