Abstract
Herein, optimal groundwater pumping solutions based on a variety of energy resources and water storage options are estimated and classified. Each energy source and water storage option is first characterized considering energy, economic, and environmental criteria. A multi-criteria decision making (MCDM) process based on the analytic hierarchy process (AHP) and the technique for order performance by similarity to ideal solution (TOPSIS) is subsequently applied to identify and classify the optimal groundwater pumping solutions under such a multidimensional framework. An aquifer located in the southeast of Spain is analyzed in a case study to assess the proposed optimal MCDM-based approach. Conventional diesel-based equipment, solar PV power plants, and direct grid connection, as well as three water storage systems––direct pumping, seasonal storage, and annual storage––are identified as potential energy sources and water storage options, respectively. Characterization and visualization of these energy and water storage systems, as well as prioritized option results, are also discussed herein.
Highlights
With the relevant integration of renewable energy sources (RES) into most of the sector, renewables currently represent an energy transition opportunity in agriculture [1]
A multidimensional analysis, including economic, energy, and environmental (3E) criteria, is proposed to characterize different groundwater pumping solutions based on energy resources and water storage options
The Analytic Hierarchy Process (AHP)/TOPSIS method is used to prioritize the groundwater pumping alternatives depending on the corresponding water storage conditions and the selected energy resourced (PV, diesel, or grid)
Summary
With the relevant integration of renewable energy sources (RES) into most of the sector, renewables currently represent an energy transition opportunity in agriculture [1]. Solar photovoltaic (PV) water pumping systems can be used efficiently for water pumping in agriculture [4]. They play a vital role in reducing the consumption of conventional energy sources and their environmental impact for water pumping applications [5]. PVWP solutions have rarely been implemented, and they are considered as electric energy sources only in remote locations [11, 12], as a part of hybrid solutions —i.e. integrating fuel cells and solar panels [13], or as standalone solar PV with groundwater pumpedhydro-storage systems [14]. Sampedro et al recently affirmed that fossil fuel subsidies are one of the most prominent barriers to tackling climate change, encouraging inefficient energy consumption, and diverting investment
