Abstract

Off-river pumped hydro energy storage (PHES) is a developing technology that requires ongoing evidence to support its growth. Economic and environmental analyses demonstrating off-river PHES as a promising energy storage system (ESS) are explained in this study. A case study was conducted using Java-Bali data, Indonesia. This study compares the economic and environmental potential of off-river PHES with lithium-ion battery (LiB) and compressed air energy storage (CAES) systems. Additionally, this study examines the integration of these technologies with offshore wind, solar, and geothermal energy mixes using hourly weather and supply-demand data. Results indicate that off-river PHES is superior economically and environmentally. For Java and Bali, off-river PHES requires the lowest investment for annual electricity generation, with total project costs ranging from $0.04 billion/year to $157 billion/year and annual operation and maintenance (O&M) cost or OPEX from $0.02 billion/year to $76 billion/year. Despite high annual OPEX, off-river PHES emits the least CO₂ at 3 Mt/year, reducing emissions by approximately 97 % compared to coal-based power plants. Next, social and technical considerations provide a more comprehensive feasibility comparison between the involved ESS. Ultimately, this paper provides scientific evidence supporting off-river PHES for renewable energy-based hourly electricity generation.

授权河外抽水蓄能：可再生能源生产-储存系统的经济和环境分析

河外抽水蓄能（PHES）是一项发展中的技术，需要持续的证据来支持其发展。经济和环境分析表明，河外PHES作为一个有前途的能源存储系统（ESS）在本研究中解释。使用印度尼西亚的Java-Bali数据进行了一个案例研究。本研究比较了河外PHES与锂离子电池（LiB）和压缩空气储能（CAES）系统的经济和环境潜力。此外，本研究利用每小时天气和供需数据，考察了这些技术与海上风能、太阳能和地热混合能源的整合情况。结果表明，河外PHES具有较好的经济性和环保性。对于爪哇和巴厘岛来说，河外PHES每年发电所需的投资最低，项目总成本从4亿美元/年到1570亿美元/年不等，年运营和维护成本或运营成本从0.02亿美元/年到760亿美元/年不等。尽管年运营成本很高，但河外PHES排放的二氧化碳最少，为300万吨/年，与燃煤电厂相比，排放量减少了约97% %。其次，社会和技术方面的考虑为所涉及的ESS提供了更全面的可行性比较。最后，本文提供了支持河外PHES以可再生能源为基础的小时发电的科学证据。
