Simulation of a Tidal Current-Powered Freshwater and Energy Supply System for Sustainable Island Development

Sustainable development of islands cannot be achieved without the use of renewable energy to address energy and freshwater supply issues. Utilizing the widely distributed tidal current energy in island regions can enhance local energy and water supply security. To achieve economic and operational efficiency, it is crucial to fully account for the unique periodicity and intermittency of tidal current energy. In this study, a tidal current-powered freshwater and energy supply system is proposed. The marine current turbine adopts a direct-drive configuration and will be able to directly transfer the power of the turbine rotation to the seawater pump to improve the energy efficiency. Additionally, the system incorporates batteries for short-term energy storage, aimed at increasing the capacity factor of the electrolyzer. A simulation is conducted using measured inflow velocity data from a full 12 h tidal cycle. The results show that the turbine’s average power coefficient reaches 0.434, the electrolyzer’s average energy efficiency is 60.9%, the capacity factor is 70.1%, and the desalination system’s average specific energy consumption is 6.175 kWh/m3. The feasibility of the system design has been validated.

CSP+MED Plant Coupled to a Seawater Pipeline from the Mining Industry in Northern Chile: A Case Study

The study evaluated the use of mining seawater pipelines in a CSP+MED plant at commercial scale based on solar tower molten salts technology, with 111.2 MWe and 13 hours of thermal energy storage in northern Chile. The plant is coupled to the biggest seawater pipeline in the country, from Centinela mining facility. Results shown that the CSP+MED plant required all the seawater pumping capacity of the pipeline in order to cool the thermal cycle of the CSP plant using the MED plant. In terms of electricity production, the MED plant integration affects significantly the annual electricity production of the plant, when compared with an optimized CSP plant and to a CSP plant with the same design but without the MED plant and considering a once through cooling system, lowering the electricity production an 46.05% and 25.82% respectively. On the other hand, the CSP+MED plant integration produces 14.06 hm3 of freshwater annually, which translated in an additional income equivalent to 28.14 MM USD each year, which is substracted from the OPEX costs of the plant for the LCoE calculations. For this reason, the results showed that the lowest LCoE is reached by the CSP+MED plant configuration, but is highlighted that the economic analysis assumed an ideal situation, and further business models must be studied in order to share the benefits of the seawater pipeline integration between the CSP+MED plant owner and the mining facility that owns the seawater pipeline.

A system-level CFD simulation model for investigating the energy dissipation mechanism of seawater pump and rotary energy recovery device in SWRO desalination system

Seawater reverse osmosis (SWRO) technology has been universally adopted because of its high efficiency, economic benefits, easy maintenance, and high-pressure seawater pump (HPSP) and energy recovery device (ERD) are essential components, which determine the specific energy consumption of SWRO system. However, it is still unclear about energy dissipation mechanism and mixing characteristics from the perspective of system. For that, this thesis proposes a novel system-level Computational Fluid Dynamics (CFD) model considering all interfaces in HPSP and integrated energy recovery and pressure boost device (IERPBD). To profoundly investigate the system performance under various operating conditions, the pressure and composition distribution, power loss of each interface and mixing rate are numerically calculated and analyzed. Additionally, experiment of the effect of temperature on SWRO system performance is conducted to practically verify the proposed model, which indicates that the presented model could precisely reflect the energy dissipation and mixing characteristics. Besides, it is advised that the rotating speed of HPSP and IERPBD should not be set too high which could increase the mixing rate and energy consumption, and higher temperature might lower the quality of produced freshwater. This study offers a feasible way to reveal the energy dissipation mechanism of SWRO desalination system.

Effects of operating parameters and particle friction on water usage of deep-sea manganese nodules hydraulic conveying equipment

One of the primary concerns for commercialising deep-sea mining is the environmental impact associated with the pumping seawater. Therefore, this study developed an unresolved coupled model of Computational Fluid Dynamics - Discrete Element Method (CFD-DEM) to explore water usage under various operating conditions. The model was validated by experimental results from previous research. The study specifically focused on examining the effects of particle friction on the particle output rate and water usage. The results indicated that to minimise the usage of seawater, the injecting speed should be set at a relatively high value to achieve a high discharge rate, such as 3 m/s in this work. The injecting speed for large particles can be set lower than that for small particles. It is recommended to set the pumping flow rate at a relatively low value, as long as it can generate enough lift force to transport the particles.

Design and simulation of an off-grid marine current-powered seawater desalination and hydrogen production system

The use of marine current energy to provide a stable supply of energy and fresh water to islands and remote areas is a promising prospect. In this study, an integrated marine current-powered seawater desalination and hydrogen production system was proposed. For higher integration and efficiency, the generator and seawater pump were integrated into the nacelle and mechanically connected to the main shaft. Four operating modes and the corresponding start-stop and maximum power point tracking (MPPT) control strategy were designed to achieve energy distribution between the two loads. Considering the frequent start-stop caused by the sinusoidal characteristic of marine current energy, a soft start-up process was designed for the RO elements, including dual hydraulic accumulators and a smooth transition process to avoid abrupt changes in feed pressure and feed flow rate. Finally, the performance was obtained by simulation. During the 6 h of the ebb tide, the desalination system produced a total of 841.77 L of fresh water, while the electrolyzer produced 1038.5 SL of hydrogen and consumed 0.95 L of water. The average power coefficient of the turbine was 0.434, and the specific energy consumption of the desalination system was 2.03 kWh/m3, indicating good MPPT performance and high efficiency.

A Study of PI Controller Tuning Methods Using the Internal Model Control Guide for a Ship Central Cooling System as a Multi-Input, Single-Output System

Since the variable-speed seawater pump and the three-way valve of a ship’s central cooling system are forms of feedback from the same output signal, these controllers may cause interference when they are not coordinated. Therefore, studying an efficient control tuning method for a central cooling water system is necessary. In this study, a central cooling water system is modeled using Matlab Simulink by utilizing an actual operation dataset, and unknown parameters are estimated for fine-tuning. The simulation model is then verified using the second operating dataset. Additionally, transfer functions are developed for the freshwater output temperature against the three-way valve openness input and the electrical power frequency input to the seawater pump motor, supposing that the two systems are independent. Then, the two PI controllers are tuned using internal model control (IMC) filters. Moreover, the modified internal model control tuning method is suggested, using the character of the central cooling system, which has a large time constant for the heat exchanger system with the seawater pump and a small time constant for the three-way valve system. This method simplifies the tuning of the two combined PI controllers, enhancing the seawater pump’s overall efficiency and the three-way valve’s operation. This study presents the proposed tuning methods based on the IMC filter and modified IMC guide, which confirmed the simple determination of the gain values of the PI controller with the efficient control of the rotational speed of the seawater pump and the three-way valve with reasonable control of the freshwater outlet temperature.

Pengembangan Alat Desalinasi Air Laut dengan Teknologi Thermal Energy Storage

The need for clean water in household life is very important because humans cannot live without it. The composition of seawater consists of 96.5% pure water and 3.5% other materials, namely salts, dissolved gases, and others. Indonesia is one of the countries that has the second-longest coastline in the world, so the potential for utilizing sea water is very large, one of which can be through the desalination process. Distillation itself is distillation, and its by-product is salt when seawater is heated using a heat energy source with a concentrated solar power (CSP) system. Based on research that has been done previously, the tool is a lab-scale seawater desalination device, but the process of making a lab-scale seawater desalination tool is not optimal. Then design the construction of a lab-scale seawater desalination device with the Multi Stage Flash (MSF) type, and the aim is to determine the performance and functionality of the MSF-type lab-scale seawater desalination device. The results show that the results of the coil heat exchanger development obtained an inlet temperature of 85.9°C and an outlet temperature of 67.8°C, and the room temperature in the chamber can be maintained at a temperature of 68.9°C. As for the components being developed, such as sea water pumps, hoses, tees, and sprayers, a sea water debit of 53.78 liters per hour has been obtained.

Research on the Energy Savings of Ships’ Water Cooling Pump Motors Based on Direct Torque Control

This study presents a Simulink model and the simulation of a central water cooling system and the main seawater pump motor of a 59,990 DWT bulk carrier, based on a direct torque control strategy to control the frequency of the ship’s water cooling pump motors. Simulation curves of the water cooling system under different sailing conditions were simulated based on 100% of rated power, 80% of common power, and the seawater temperature of the ship’s main engine. The simulation of the current, speed, and torque of the pump motor under direct torque control verified that the ship’s water cooling pump motor could save approximately 22.70%, 36.76%, and 52.70% of electrical energy, respectively, throughout the year with this inverted control solution.

Efforts To Improve Cooling Water Treatment On The Performance Of Master Engines On Ship KM. Camara Nusantara 1

The cooling system is a medium that serves to absorb heat. The heat is obtained from the combustion of fuel in the cylinder. engine cooling is intended to maintain a stable temperature in the engine so that there is no too high temperature increase as a result of the combustion of fuel in the cylinder and the friction that occurs. Cooling the engine is also intended to reduce the risk of damage. The diesel engine cooling system is divided into 2, namely a closed cooling system and an open cooling system. The open cooling water system has an average temperature of 300 Celsius and the closed cooling water system has an average inlet temperature of 400 Celsius and an outlet temperature of 700-800 Celsius. Problems that often occur in the cooling water system are broken shaft impellers for seawater pumps, pipe leaks and capillary pipes clogged with dirt. The results of the writing refer to the damage to these components, this causes the fresh water temperature to rise. Therefore, regular and systematic maintenance and repair of these components is absolutely necessary for the cooling system to work optimally.

Research on Two-stage Humidification-dehumidification Heat Pump Desalination System

For the humidification-dehumidification desalination unit to perform more efficiently, a two-stage humidification-dehumidification heat pump desalination system was proposed. So as to improve the heat and mass transfer effect between seawater and moist air, the two-stage humidifier was employed to recover the waste heat of seawater discharged from the first stage humidifier. The models of a one-stage and two-stage humidification heat pump seawater desalination system were built using Aspen Plus simulation software. Multi-condition simulation studies were carried out for different inlet seawater temperatures, liquid-gas mass ratios, and refrigerant flow rates of the heat pump. According to the comparative examination of the simulation’s outcomes, it is concluded that: with the increase in inlet seawater temperature and liquid-gas flow ratio, the two-stage humidifier system’s recovery rate and gain output ratio are superior to those of the first-stage humidifier system, and the inlet seawater temperature and circulating airflow needed for the two-stage humidifier system to perform at its best are less demanding than those for the first-stage humidifier system., indicating that the two-stage humidifier dehumidification desalination technology of the heat pump has great performance improvement and a broad application prospect.

Performance Evaluation of Control Compatibility for an OTEC Pump Shutdown Condition

South Korea is currently in the preparatory stage of commercializing an ocean thermal energy conversion (OTEC) system, as the demonstration of a 1 MW scale OTEC system has been accomplished. However, the commercialization of OTEC requires the establishment of a control system for various environmental changes. Therefore, pre-emptive identification of the system’s risk factors and the process of analyzing the impact of the system, building control items, and optimizing control are necessary. This study aims to establish and analyze an optimized control system for MW-scale OTEC risk factors, such as the shutdown of seawater or refrigerant pumps. The selected OTEC system was designed for 1070 kW class facilities, with a 36.6% portion of total electricity usage by the seawater pump and refrigerant pump. As a result, an on/off control system was adopted in order to eliminate the risk factors. By adjusting this option, dry operation of the refrigerant pump, water hammering, and liquid inflow into the turbine were successfully prevented. To be more specific, the initial system was to be shut down due to a sharp decrease in power at the point where the deep seawater flow rate was 538 kg/s (35.7% of max flow rate) and the surface seawater flow rate was 715 kg/s (38.4% of max flow rate). This situation was improved by adopting parallel operation of seawater pumps and on/off control, thereby leading to a more stabilized operation by maintaining a flow rate of over 1864 kg/s for surface seawater and 1507 kg/s for deep seawater. Moreover, it was confirmed that the flow rate of the pump was reduced by 1.89 kg/s per second in the process of pump shutdown during a single operation mode of the refrigerant pump. Parallel operation made it possible to maintain 60.2% of the output by increasing the power of the second pump’s flow rate in the event of the first pump shutting down. The final seawater temperature differential power generation model derived from this study consists of two refrigerant pumps and two surface seawater and deep seawater pumps in order to prevent system shutdown caused by a single pump failure. The final design was reflected in the final delivery to Kiribati, which is located near the equator.

Integration of desalination and energy conversion in a thermo-osmotic system using low-grade heat: Performance analysis and techno-economic evaluation

Freshwater and electricity cogeneration systems, using renewable energy sources, can play a crucial role at the water-energy nexus. By placing a hydrophobic, porous membrane between a hot saline water flow and a pressurized cold freshwater flow, thermal-osmotic energy conversion and thermal-osmotic desalination can be implemented simultaneously. A novel open-loop freshwater and electricity cogeneration system is proposed and evaluated, which consists of a hydrophobic membrane module, a seawater pump, two heat exchangers, and a hydraulic turbine. In the base case designed for a daily freshwater production of 3.9 × 104 m3/day, the net power output is estimated to be 2.15 MWe and the energy efficiency of power generation is 0.24%. Considering the economic benefits brought by the electricity production, the water production cost is 0.36 $/m3 with a global average industrial electricity price of 0.11 $/kWh. Compared with the commercial reverse osmosis desalination technology, the desalination cost of the hybrid system is reduced by over 28%. The parameter analysis is carried out and reveals that optimizing membrane properties and operating conditions can greatly improve the energy efficiency and reduce the water production cost. Improving the liquid entry pressure and permeability coefficient and reducing the thermal conductivity of the membrane are the key to improving the application prospect of the system.

Net Power Generation Control of OTEC Plant Using Rankine Cycle with Seawater Pumps by Warm Seawater Flow Rate Regulation*

In this research, net power generation control of an ocean thermal energy conversion (OTEC) plant using Rankine cycle is investigated. In the model construction, not only the seawater pumping powers described by static characteristics but also the net power output is taken into account. The dynamics of the heat exchangers are also considered, where they are represented as the first-order systems. For the plant model, proportional integral controller is designed so as to satisfy some specifications, where as the manipulated variable the warm seawater flow rate is adopted. The effectiveness of the proposed control system was confirmed by numerical simulations.

Assessment of Biogrowth at Two Different Environments of Nuclear Power Plant Cooling Water System Located at Southern Coast of India

A systematic assessment of biogrowth development on titanium coupons exposed to ambient seawater (intake) and chlorinated seawater (pump house) environments of a coastal nuclear power plant was carried out. Titanium coupons were exposed for a period of 2 years and periodically removed at monthly intervals for biogrowth assessment. Biofouling biomass at the seawater intake station ranged from 0.8-12.5 kg m-2 during the 2 years of study. Continuous chlorination of 0.2 ± 0.1 mg L-1 and shock dose chlorination for 1 h/day at residuals of 0.4 ± 0.1 mg L-1 was very effective in reducing the biofouling load in the cooling water system. A reduction in fouling biomass of 95% was observed on titanium coupons between the intake and the pump house stations. Biofoulants recruitment was found to occur throughout the year at varying intensities. Diversity of organisms on the coupon was influenced by seasonality and distinct successional patterns were observed at the seawater intake. Barnacles were the dominant fouling organisms followed by mat forming ascidians, bryozoans, oysters, hydroids and seaweeds at the intake station. Sluggish biofouling development was observed on coupons at the intake due to the sub-tidal intake system (-5 m), which had a lesser load of meroplanktonic organisms. The study also showed that low dose continuous chlorination was an effective strategy for biofouling control in the cooling water system of the tropical power station which uses titanium heat exchangers for steam condensation.

Data driven-based model for predicting pump failures in the oil and gas industry

Equipment reliability is a critical aspect of the oil and gas industry because the failure of such equipment can lead to catastrophic outcomes on different levels. In these industries, the need for safe, accurate, and cost-effective equipment operation requires reliable failure estimation and identification in order to improve performance and ensure that the maintenance strategy is efficient and effective. Thus, failure prediction is vital in the oil and gas industries for extending part lifetime and reducing unexpected equipment failures, thereby avoiding costly plant shutdowns and equipment damage. This paper proposes a simple and easy-to-implement data-driven model based on multiple linear regression for predicting the failures of a seawater pump in the oil and gas industry. Real-world historical data from equipment and process sensors mounted on the selected pump is collected and analyzed to develop the proposed model. The factors used to build the proposed model have been identified through a review of the literature and expert interviews. In addition, the correlation between the input factors is investigated. The results revealed that the proposed model has the capability to predict pump failure with more than 97% accuracy. Furthermore, sensitivity analysis revealed that temperature and pressure are the most important factors influencing pump failure. The findings of the proposed model can assist maintenance managers and decision-makers in properly detecting and predicting failure. It also helps to monitor and control the input factor levels in order to prevent failures. This study contributes to the development of failure prediction alerts, which will serve as a maintenance decision support system for operatives to avoid potential incoming failures.

Effect of Mucilage Pollution on Ship Cooling Systems: A Case Study

In recent years, ecological degradation has increased and drawn many environmental problems with it. One of the outcomes is the mucilage problem, which directly affects tourism, fishing, and especially the maritime sector. The recent mucilage outbreak in the Sea of Marmara has brought attention to these environmental disaster-related studies. However, there are only a few studies about mucilage’s effect on maritime transportation. In this context, the impact of mucilage on a marine vessel is examined within the scope of the study. One of the major negative effects of mucilage on a vessel is, its cooling system. Due to the mucosal formation of mucilage, it clogs the filters and reduces the cooling effect of seawater. In our paper, a case study was made, and data was obtained from a simulator. The seawater filter in front of the seawater pump was clogged by 0%, 30%, 45%, and 60% during the simulated case studies. 0% is the base condition that is not clogged by the mucilage while the other three cases are partially clogged. A comparison study was made according to the data gathered from the simulator. While the filter is clogged by 60% main engine is in slow down condition, but during 30% and 45% of cases, pumps tried to compensate cooling effect by increasing the seawater flow. However, enough cooling effects on the main engine jacket water, air cooler, lubrication oil cooler, steam condenser, and air compressor were not provided. Moreover, the reduced cooling effect increases fuel oil consumption which leads to higher CO2 emissions. These results show that mucilage not only affects fishing, and tourism but also affects the environment by increasing the fuel oil consumption of a vessel.

Разработка системы охлаждения судовых малоразмерных дизелей, работающих при различных температурах забортной воды в условиях лаборатории

Using a cooling system in water transport is considered the most effective way to increase the energy efficiency of a vessel. Currently, closed-loop cooling systems and frequency-controlled drives of seawater electric pumps are actively used. An option of improving the energy efficiency of cooling systems with mounted seawater pumps is being studied. The hydraulic scheme of the unit with an energy-efficient ship engine cooling system is presented. To study ways to reduce mechanical losses in the drive of auxiliary mechanisms of a marine engine, the laboratory “Marine Diesels” of Astrakhan State Technical University developed a test bench for the Iveco 8041I06 engine. The engine cooling system does not have a thermostat to control the thermal state; instead of a thermostat on the engine, an electronically controlled variator is installed between the engine power take-off shaft and the VKS 1/16 pump. At a constant engine speed, the variator allows changing the pump speed, supply of sea water through the heat exchanger and regulating the thermal state of the engine. It has been found that during engine tests it is necessary to maintain the temperature of the outboard water constant. A description is given of the use of tanks with thermal insulation at the stand to reduce heat exchange with the environment. Variants of types of containers and materials for insulation are considered. To prepare water of the required temperature a chiller is connected to the cooling system at the experimental stand. The calculation of thermal insulation and comparison of the result with a real test is given. On the stands for testing diesel engines the change in the thermal state of the engine is carried out only by changing the load on the engine. On the developed stand, the thermal state can also be changed, including by controlling the seawater temperature, which expands its capabilities for modeling real processes.

Performance study on the seepage and heat transfer in a bench-scale multi-well infiltration intake system for seawater source heat pump

The Beach Well Infiltration Intake (BWII) system is one of the various methods for pumping seawater for Seawater Source Heat Pump (SWHP) systems that improve the stability, reliability, and energy efficiency of the SWHP systems in cold climate areas. Because of the limitations of the site conditions, it is difficult to perform experimental studies on the BWII system under different experimental conditions, especially for multi-well systems. Therefore, a BWII experimental system that incorporated nine beach wells was established in a laboratory in this paper. The goal was to study the seepage and heat transfer performance of the multi-well infiltration intake system and calculate the influencing range for pumping groundwater on sands in a sandbox. Then, an established seepage and heat transfer model of the BWII system was validated by the experiment. Based on the validated model, the method for designing an experimental sandbox was studied. The research results showed that the effective width increased with an increase in the distance between the pumping well and the long water tank. However, the effective width in the back part of the pumping well decreased with an increase in this distance. The result that the effective length decreased with an increase in this distance was contrary to our subjective expectations. When the distance between the pumping well and the long water tank was 0.5 m, the effective length and effective width were 1.5 ∼ 2.1 m and 0.9 m respectively. The formulas of the effective width and the effective length were derived. The experimental study provided a method to study the seepage and heat transfer performance of the BWII system and was complementary to the theoretical research and the practical engineering field research. The research results provided in this study will contribute to the establishment of a set of seepage heat transfer similarity test methods.

Weddell seal pups keep swimming when trading in fluff to cut costs

Open water swimming is not for the faint hearted, especially when air and water temperatures tumble. But spare a thought for furry Weddell seal pups born on the Antarctic sea ice. Although their blanket of fluffy insulation works fine when dry, as soon as the pups plunge into the sub-zero waters, all benefits are lost. And the youngsters can take to the water learning to swim and dive as early as 2 days old. So, how do the seal pups cope when they shed their fur, relying instead on their developing blubber stores for insulation? ‘We aimed to understand how pups stay warm on ice and in water and if older pups with more blubber use less energy to stay warm in the water’, says Linnea Pearson from California State Polytechnic University (Cal Poly), USA, who headed south with Emma Weitzner, Lars Tomanek and Heather Liwanag (also from Cal Poly) to the McMurdo Station in Antarctica – close to a colony of Weddell seals – to monitor newborn pups through the first weeks of life.‘Weddell seals are relatively calm, which makes working with them easier’, says Pearson, who weighed and measured the pups while also noting the condition of their fur as they moulted and became sleeker over a 7 week period. In addition, the team placed the pups inside a custom-built plastic chamber to measure their oxygen consumption when on the ice. Then, they removed the youngsters and pumped sea water into the chamber up to the height of each pup's chest before returning the youngsters to find out how their metabolism changed when immersed. ‘You could tell most were already familiar with that environment’, says Pearson. ‘One kept blowing bubbles under the water. While cute, we had to get it to stop to get our data’, she chuckles. In addition, the team tracked how often and for how long each pup went for a dip by tagging the youngsters’ hind flippers before returning them to their mums.Back in California, the team calculated the pups’ metabolic rates when dry on the sea ice and sure enough, as the pups grew, their metabolic rates increased. However, when immersed in water, the 3- and 7-week-old pups had similar metabolic rates. ‘This may represent a maximum thermal response of pups to submergence in water’, says Pearson, adding that the youngest animals may be diverting more of their resources to speed up their moult and build up their blubber insulation faster.However, when the team compared the metabolic rates of the youngest seals before they moulted, during the moult and after, they found clear differences at each stage. The pre-moult pups had the highest metabolic rates when immersed, consuming ∼13.4 ml O2 min-1kg-1, compared with ∼9.4 ml O2 min-1kg-1 when dry. Yet, while moulting and by the time the time the pups had discarded their fur, their metabolic rates when immersed had declined, eventually reaching ∼8 ml O2 min-1kg-1. In addition, the fully moulted youngsters expended the same amount of energy when immersed and on the sea ice; they were no longer working hard to keep warm in the chilly water.The team then compared how much time the youngsters were spending in the water before, during and after moulting, and were astonished that the moulting pups were spending three times as much time swimming as they did before and after the moult, even though they were expending more energy to remain warm in the water. The team suspects that the swimming and diving experience they gain while moulting may justify the expense, setting the youngsters up for a life of self-sufficiency when finally abandoned by their mothers.

Assessing the synergy between a seawater pumping system for mining facilities and the cooling system of a CSP plant in Northern Chile

The Atacama Desert presents the highest Direct Normal Irradiance (DNI) levels on the planet and at the same time is one of its driest places on Earth. The region concentrates a large number of copper mining facilities and is currently considered as a hotspot for the deployment of solar technologies. The mining activity consumes large amounts of water in its processes, and for driving such processes several of the facilities consider seawater pumping systems. The present article describes a technical and economic evaluation of coupling the cooling system of a Concentrating Solar Power (CSP) plant and the seawater pipeline. The analysis considers a location in northern Chile and the operation of a CSP plant, which is assessed using a validated simulation tool. The base scenario considers evaporative cooling, which is compared to other cooling approaches such as: dry cooling, once through, and coupling a Multi Effect Distillation (MED) plant, where the last two consider a connection to the pumping pipeline. The energy production and the resulting economic benefit are evaluated for each cooling scenario. It is observed that the scenarios using seawater deliver more energy than the dry cooling scenario. The once-through and MED cases show the best economic performance in terms of the Net Present Value (NPV). The simulations carried out allowed to identify the synergistic performance between the mining pumping system and the operation of the CSP plant, enabling to exploit additional benefits from its integration.
