摘要

本研究调查了不同储能技术在欧洲电力部门中的作用，该部门符合2050年净零碳排放的目标。我们考虑了三种储能技术，即电池、抽水蓄能和氢存储。我们发现一个国家的最低成本储能组合取决于发电组合，并根据当前的储能技术确定了欧洲的三个国家原型。在可用的情况下，抽水蓄能在储能组合中占主导地位，减少了对新电池和储氢装置的需求。总体而言，短期电池储能能最好地捕捉太阳能波动，并与太阳能发电相结合，而长期储氢能同时补偿太阳能和风能的峰值发电。此外，我们量化了以不同空间分辨率和净自给自足尺度（从区域到大陆）对欧洲系统建模对最佳储能组合的影响。不同空间分辨率的对比评估表明，随着空间分辨率的提高，储能装置的安装量，尤其是储氢装置的安装量显著增加。

The role of energy storage towards net-zero emissions in the European electricity system

This study investigates the role of different energy storage technologies in a European electricity sector that complies with the target of net-zero carbon emissions in 2050. We consider three energy storage technologies, namely battery, pumped hydro, and hydrogen storage. We find that the cost-minimal energy storage mix in a country depends on the generation mix, and we identify three country archetypes in Europe based on the prevailing energy storage technology. When available, pumped hydro dominates the storage mix, reducing the need for new battery and hydrogen storage installations. Overall, short-term battery storage best captures solar fluctuations and is optimally combined with solar generation, while long-term hydrogen storage compensates for both solar and wind peak generation. Moreover, we quantify the impact of modeling the European system with different spatial resolutions and net self-sufficiency scales, from regional to continental, on the optimal energy storage mix. The comparative assessment of different spatial resolutions shows that the amount of energy storage installed, and especially the amount of hydrogen storage, increases significantly for higher spatial resolutions.

期刊介绍： The journal Energy Conversion and Management provides a forum for publishing original contributions and comprehensive technical review articles of interdisciplinary and original research on all important energy topics. The topics considered include energy generation, utilization, conversion, storage, transmission, conservation, management and sustainability. These topics typically involve various types of energy such as mechanical, thermal, nuclear, chemical, electromagnetic, magnetic and electric. These energy types cover all known energy resources, including renewable resources (e.g., solar, bio, hydro, wind, geothermal and ocean energy), fossil fuels and nuclear resources.
