Abstract The development of efficient and sustainable energy solutions and the attempt to reduce carbon dioxide emissions are leading to an increasing penetration of Renewable Energy Sources (RES). Effective Electrical Energy Storage (EES) solutions need therefore to be developed to deal with the issue of fitting locally available RES and loads. Hydrogen can become an interesting option because of its high energy density, long-term storage capability and modularity. In particular, in isolated micro-grid and off-grid remote areas, intermittent RES integrated with H2-based storage systems can allow to lower, or even eliminate, the usage of diesel engines and avoid the need for expensive and invasive grid connections. The present study is part of the European REMOTE project, whose main goal is to prove the added value of H2-based energy storage solutions with respect to alternative technologies in terms of economics, technical and environmental benefits. Four demonstration sites supplied by renewable electricity will be installed in either isolated micro-grids or off-grid remote areas throughout all Europe, from Italy (two sites) and Greece to Norway. The aim of this work is to perform a techno-economic analysis and demonstrate the effectiveness of the hybrid H2-battery Power-To-Power (P2P) solution in reducing the usage of external sources (e.g., diesel engines or grid) in a cost-effective way, with different load and environment conditions. The economic viability of the considered scenarios was outlined by computing the Levelized Cost Of Energy (LCOE). For each of the four sites, the innovative renewable configuration was compared with the current/alternative one. The REMOTE project partners provided main input data for the analysis: techno-economic data from the technology suppliers, whereas electricity consumption and RES production values from the end users of the four isolated locations. LCOE values derived using cost inputs both from REMOTE and literature are presented for a comparison. Results from the energy simulations revealed that the need for an external source is significantly reduced thanks to RES together with the hybrid storage system. Moreover, for all the four sites the renewable solution was shown to be more profitable than the current or alternative one, either in the short term or in the longer term.

偏远地区氢气储能系统技术经济可行性研究

摘要 高效和可持续能源解决方案的开发以及减少二氧化碳排放的尝试导致可再生能源 (RES) 的日益普及。因此,需要开发有效的电能存储 (EES) 解决方案来解决安装本地可用 RES 和负载的问题。氢能成为一个有趣的选择,因为它具有高能量密度、长期存储能力和模块化。特别是,在孤立的微电网和离网偏远地区,间歇性 RES 与基于 H2 的存储系统集成可以降低甚至消除柴油发动机的使用,并避免对昂贵且侵入性的电网连接的需求。本研究是欧洲远程项目的一部分,其主要目标是证明基于 H2 的储能解决方案在经济、技术和环境效益方面相对于替代技术的附加值。四个由可再生电力提供的示范站点将安装在整个欧洲的孤立微电网或离网偏远地区,从意大利(两个站点)和希腊到挪威。这项工作的目的是进行技术经济分析,并证明混合 H2 电池电力到电力 (P2P) 解决方案在减少外部资源(例如柴油发动机或电网)的使用方面的有效性- 有效的方式,适用于不同的负载和环境条件。通过计算平准化能源成本 (LCOE) 概述了所考虑情景的经济可行性。对于四个站点中的每一个,将创新的可再生配置与当前/替代配置进行了比较。REMOTE 项目合作伙伴为分析提供了主要输入数据:来自技术供应商的技术经济数据,而来自四个孤立地点最终用户的电力消耗和可再生能源生产值。使用来自远程和文献的成本输入得出的 LCOE 值用于比较。能源模拟结果表明,由于 RES 和混合存储系统,对外部能源的需求显着减少。此外,对于所有四个站点,无论是从短期还是从长期来看,可再生解决方案都显示出比当前或替代解决方案更有利可图。REMOTE 项目合作伙伴为分析提供了主要输入数据:来自技术供应商的技术经济数据,而来自四个孤立地点最终用户的电力消耗和可再生能源生产值。使用来自远程和文献的成本输入得出的 LCOE 值用于比较。能源模拟结果表明,由于 RES 和混合存储系统,对外部能源的需求显着减少。此外,对于所有四个站点,无论是从短期还是从长期来看,可再生解决方案都显示出比当前或替代解决方案更有利可图。REMOTE 项目合作伙伴为分析提供了主要输入数据:来自技术供应商的技术经济数据,而来自四个孤立地点最终用户的电力消耗和可再生能源生产值。使用来自远程和文献的成本输入得出的 LCOE 值用于比较。能源模拟结果表明,由于 RES 和混合存储系统,对外部能源的需求显着减少。此外,对于所有四个站点,无论是从短期还是从长期来看,可再生解决方案都显示出比当前或替代解决方案更有利可图。使用来自远程和文献的成本输入得出的 LCOE 值用于比较。能源模拟结果表明,由于 RES 和混合存储系统,对外部电源的需求显着减少。此外,对于所有四个站点,无论是从短期还是从长期来看,可再生解决方案都显示出比当前或替代解决方案更有利可图。使用来自远程和文献的成本输入得出的 LCOE 值用于比较。能源模拟结果表明,由于 RES 和混合存储系统,对外部能源的需求显着减少。此外,对于所有四个站点,无论是从短期还是从长期来看,可再生解决方案都显示出比当前或替代解决方案更有利可图。
