Energy recovery in irrigation networks using pumps as turbines (PAT) is a promising approach to address the challenges of water scarcity and energy efficiency in agriculture. This article provides a comprehensive overview of the concept, design considerations, operational characteristics, and integration of PAT systems in irrigation networks. By utilizing pumps in reverse as turbines, the excess pressure in the network is converted into mechanical energy, which is then transformed into electricity. The article discusses the potential benefits of PAT systems, including optimized water management, reduced energy waste, and enhanced the sustainability. It explores the economic feasibility, environmental advantages, and potential challenges associated with implementing PAT systems in diverse agricultural contexts. Furthermore, the article highlights the resilience and adaptability of PAT systems, offering decentralized and reliable energy generation solutions in areas with unreliable power supply. Through knowledge dissemination and insights, this article aims to inspire further research, development, and practical applications of energy recovery using pumps as turbines in irrigation networks, ultimately fostering a more sustainable and efficient future for agricultural practices.

“…This form of regulation implies an effective energy production lower than the maximum based on both available discharges and heads. Conversely, in ER mode, the operating speed of the generator is modified to match the load conditions determined by the instant flow discharge and head drop values, namely the PAT characteristic curve is modified to match the available head in a combined regulation (HER) [38][39][40]. The installation of a PAT + SEIG solution is presented in Figure 20 and can integrate Hy4REN as a less expensive turbine configuration.…”

A review of different energy components is detailed, as a baseline of fundamentals for the new integrated energy concept idealization. This innovative solution is a Hybrid for Renewable Energy Network (Hy4REN) based on well-studied elements to produce the best final solution. This proposal has the objective of improving energy system sustainability, facing fossil fuel and climate change restrictions, and increasing energy network flexibility. The most mature energy storage technology, pumped hydropower energy storage (PHES), is used to support both the grid connection and stand-alone modes, as an integrated hybrid energy system. The hybrid system idealization is modular and scalable, with a complementary nature among several renewables, using sea water in offshore mode to build an integrated solution. By evaluating a variety of energy sources, complemented with economic analysis, the benefits associated are evidenced using this sustainable methodology based only on renewable sources. Combined production of hydropower, using sea water, with pumped storage and water hammer events to create potential energy to supply hydropower in a water loop cycle, without consuming electrical energy, is explored. Other renewable sources are also integrated, such as floating solar PV energy and an oscillating water column (OWC) with coupled air-venting Wells and wind turbines, all integrated into the Hy4REN device. This complementarity of available sources allows us to improve energy storage flexibility and addresses the energy transition toward net-zero carbon emissions, inducing significant improvements in the sustainability of the energy network as a whole.

The Water-Energy-Food (WEF) Nexus has gained recognition as an innovative approach for analyzing the interconnectedness of global resource systems and achieving sustainability goals. In the Mediterranean, where water scarcity, climate change, and ecosystem degradation pose significant challenges, implementing an integrated Nexus approach is crucial. Through an integrative review of 136 scientific articles, we found that water-energy interlinkages dominate Nexus research in the Mediterranean, driven by the need for energy-intensive water distribution systems to meet drinking and irrigation water demands. However, the expansion of the Nexus approach to other components is limited, mostly focusing on assessing impacts on the physical environment and climate, without capturing feedback dynamics.Furthermore, Nexus research in the Mediterranean is primarily conducted at isolated case study levels, with few studies working at the entire Mediterranean scale. There is promising evidence of Nexus research expanding to socio-economic interactions, cultural and behavioral change, and resource governance innovations, but these domains remain segregated due to limited integration of methods across disciplines. To advance Nexus implementation in the region, sustainable technology and natural resources management, which are key fields of operationalization, would benefit from harmonization.In conclusion, Nexus research in the Mediterranean would benefit from integrating knowledge in multi-scale, multi-sector, and multi-dimensional frameworks to support technological, socio-economic, and governance interventions. This would enable a more comprehensive and coherent approach towards achieving water, food, and energy security while preserving the environment in the Mediterranean region.
