摘要

采矿作业是智利北部地区最重要的工业活动，那里大量使用化石燃料。本文开发了一个绿色氢综合体的技术经济评估，该综合体旨在为固定式柴油发电机（小规模项目）和燃料电池卡车（中型项目）提供燃料，该公司致力于为采矿业开采石材。考虑到地理位置、太阳能资源和公司布局，氢综合体由光伏电站、电解槽、氢压缩机和储氢装置组成。经济评价考虑了平准化电力成本（LCOE）和平准化氢成本（LCOH），包括投资和敏感性分析。对于小型项目，在1000平方米的面积上安装一个60千瓦的光伏电站，投资6.9万美元，平均LCOH为4.88美元。然而，净现值为- 47,645美元，内部收益率为- 22%，表明该项目不可行。对于中等规模的项目，在28000平方米的面积上安装1700千瓦的光伏电站，投资210万美元，平均LCOH为4.62美元。结果表明可行性、经济便利性和可扩展性，标志着该项目成为智利采矿业未来举措的先驱。

Techno-economic assessment of a green hydrogen production plant for a mining operation in Chile

Mining operations are the most important industrial activity in the northern regions of Chile with a high use of fossil fuels. This paper develops a techno-economic assessment of a green hydrogen complex designed to supply fuel to stationary diesel electric generators (small-scale project) and fuels cells trucks (medium-scale project) for a company dedicated to exploiting stone materials for the mining sector. The hydrogen complex consists of a photovoltaic plant, electrolyzers, hydrogen compressors and storage, considering geographical location, solar resource and company layout. The economic assessment considers the Levelized Cost of Electricity (LCOE) and Levelized Cost of Hydrogen (LCOH), including investment and sensitivity analysis. For the small-scale project, a 60-kW photovoltaic plant installed in an area of 1000 m², with an investment of US$ 69,000, results in an average LCOH of 4.88 US$. However, the NPV is -$47,645 and the IRR is −22%, indicating that this project is not viable. For the medium-scale project, a 1700-kW photovoltaic plant installed in an area of 28,000 m², with an investment of US$ 2,100,000, results in an average LCOH of 4.62 US$. The results indicate feasibility, economic convenience, and scalability, marking this project as a precursor for future initiatives in the Chilean mining sector.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
