Optimal Planning of Co-Located Wind Energy and Hydrogen Plants: A Techno-Economic Analysis

Abstract

Green hydrogen produced using renewable electricity could play an important role in a clean energy future. This paper seeks to analyze the techno-economic performance of integrated wind and hydrogen systems under different conditions. A co-located wind and hydrogen hybrid system is optimized to reduce the total system cost. We have adopted and improved a state-of-the-art techno-economic tool REopt, developed by the National Renewable Energy Laboratory (NREL), for optimal planning of the integrate energy system (IES). In addition to wind and electrolyzer components, we have also considered battery energy storage, hydrogen tank, and hydrogen fuel cell in the IES. The results show that (i) adding electrolyzers to the grid-connected wind energy system could reduce the total system cost by approximately 8.9%, and (ii) adding electrolyzers, hydrogen tank, and hydrogen fuel cells could reduce the total system cost by approximately 30%.

Techno-Economic Analysis Incorporating Intelligent Operation and Maintenance Management: A Case Study of An Integrated Offshore Wind and Hydrogen Energy System

“…These strategies are judiciously selected from a pool of candidates, tailed to meet energy demands at each time interval while concurrently minimizing the lifecycle cost. For an in-depth understanding of the mathematical optimization model employed, please consult our prior study [5]. In this study, we have enhanced our previous research by examining how the increased wind energy share and hydrogen production subsidies can impact the system.…”

“…This arrangement not only optimizes energy utilization but also enhances the overall stability of the energy grid. This innovation technology contributes significantly towards the attainment of ambitious sustainability goals [4]. There have been a number of studies focusing on techno-economic analysis of hybrid renewable energy systems.…”

“…There have been a number of studies focusing on techno-economic analysis of hybrid renewable energy systems. For instance, our previous studies [4,5] have focused on the technical feasibility and economic advantages of operating a hybrid wind and hydrogen system, as well as the advantages of hydrogen in playing the role of energy storage. In the study of the technoeconomic analysis of hybrid solar and hydrogen systems [6,3], the authors also focused on the economic aspects of the system only in the context of meeting the technical requirements of the system.…”

Inter-turn Short Circuit Fault Diagnosis and Severity Estimation for Wind Turbine Generators

“…Effective condition monitoring of wind turbines (WTs) is one of the most important tasks to ensure their reliable operation, energy production optimization, and minimization of maintenance expenses [1][2][3][4]. Traditional methods like direct sensing or periodic inspections, while valuable, confront limitations in cost and efficacy.…”
