In the field of desalination powered by renewable energies, the use of solar power cycles exhibits some favorable characteristics, such as the possibility of implementing thermal energy storage systems or a multi-generation scheme (e.g., electricity, water, cooling, hydrogen). This article presents a review of the latest design proposals in which two power cycles of great potential are considered: the organic Rankine cycle and the supercritical CO2 power cycle, the latter of growing interest in recent years. The designs found in the literature are grouped into three main types of systems. In the case of solar ORC-based systems, the option of reverse osmosis as a desalination technology is considered in medium-temperature solar systems with storage but also with low-temperature using solar ponds. In the first case, it is also common to incorporate single-effect absorption systems for cooling production. The use of thermal desalination processes is also found in many proposals based on solar ORC. In this case, the usual configuration implies the cycle’s cooling by the own desalination process. This option is also common in systems based on the supercritical CO2 power cycle where MED technology is usually selected. Designs proposals are reviewed and assessed to point out design recommendations.

“…Agriculture, as a vital pillar of human civilization, heavily relies on the sustainable management of water resources. Over the years, numerous researchers have diligently investigated various critical parameters, including water-use efficiency [6], convenience efficiency, crop-water requirement [7], seepage, and evapotranspiration [8,9]. Their work has shed light on the complexities of water-related challenges in agriculture, pushing us closer to achieving long-term sustainability in this crucial sector.…”

The present study provides an in-depth investigation into water security using socio-hydrological analysis by investigating the relationship between irrigation entitlements and actual water delivery. Conjoint analysis is used to evaluate the reliability and equity of the system by applying quantitative definitions and metrics. This study examines 10 years of daily average canal flow data collected from the Sindh canal command regions of the Lower Indus Basin Irrigation System in Pakistan. This research was carried out at both the canal and the barrage network levels, with socio-hydrological metrics being used across both temporal and spatial scales. Furthermore, an in-depth study of the LIB system’s fourteen main canals operating across three barrages was carried out. This research focuses on the transition from historical volumetric allocations to the objective of enhancing irrigation efficiency and agricultural yields in order to provide improved water and food security. The investigation underscores the enduring presence of stagnation and volatility in the overall equity and reliability of the system. The analysis reveals that the median reliability of the canals in Sindh was 47–100% in the summer and 65–85% in the winter season. Additionally, the irrigation system equity was worse in the winter and summer, at around 55–75%. This research examines the possibilities of using a socio-hydrological strategy to effectively improve the performance of canal irrigation systems and promote water security.

“…It was concluded that the multigeneration system with solid oxide fuel cells is more suitable for agriculture due to its useful energy products [15]. Although Azariyan et al [16] modeled a geothermal energy-based multigeneration system, the novel multigeneration system presented by Tariq et al [17] was assisted by solar energy. In both studies, it was concluded that multigeneration energy systems are sustainable and effective for global decarbonization.…”

Towards Global Cleaner Energy and Hydrogen Production: A Review and Application ORC Integrality with Multigeneration Systems

The current evidential effect of carbon emissions has become a societal challenge and the need to transition to cleaner energy sources/technologies has attracted wide research attention. Technologies that utilize low-grade heat like the organic Rankine cycle (ORC) and Kalina cycle have been proposed as viable approaches for fossil reduction/carbon mitigation. The development of renewable energy-based multigeneration systems is another alternative solution to this global challenge. Hence, it is important to monitor the development of multigeneration energy systems based on low-grade heat. In this study, a review of the ORC’s application in multigeneration systems is presented to highlight the recent development in ORC integrality/application. Beyond this, a new ORC-CPVT (concentrated photovoltaic/thermal) integrated multigeneration system is also modeled and analyzed using the thermodynamics approach. Since most CPVT systems integrate hot water production in the thermal stem, the proposed multigeneration system is designed to utilize part of the thermal energy to generate electricity and hydrogen. Although the CPVT system can achieve high energetic and exergetic efficiencies while producing thermal energy and electricity, these efficiencies are 47.9% and 37.88%, respectively, for the CPVT-ORC multigeneration configuration. However, it is noteworthy that the electricity generation from the CPVT-ORC configuration in this study is increased by 16%. In addition, the hot water, cooling effect, and hydrogen generated from the multigeneration system are 0.4363 L/s, 161 kW, and 1.515 L/s, respectively. The environmental analysis of the system also shows that the carbon emissions reduction potential is enormous.
