The waste to energy (WtE) facilities and the renewable energy storage systems have a strategic role in the promotion of the "eco-innovation", an emerging priority in the European Union. This paper aims to propose advanced plant configurations in which waste to energy plants and electric energy storage systems from intermittent renewable sources are combined for obtaining more efficient and clean energy solutions in accordance with the "eco-innovation" approach. The advanced plant configurations consist of an electric energy storage (EES) section based on a solid oxide electrolyzer (SOEC), a waste gasification section based on the plasma technology and a power generation section based on a solid oxide fuel cell (SOFC). The plant configurations differ for the utilization of electrolytic hydrogen and oxygen in the plasma gasification section and in the power generation section. In the first plant configuration IAPGFC (Integrated Air Plasma Gasification Fuel Cell), the renewable oxygen enriches the air stream, that is used as plasma gas in the gasification section, and the renewable hydrogen is used to enrich the anodic stream of the SOFC in the power generation section. In the second plant configuration IHPGFC (Integrated Hydrogen Plasma Gasification Fuel Cell) the renewable hydrogen is used as plasma gas in the plasma gasification section, and the renewable oxygen is used to enrich the cathodic stream of the SOFC in the power generation section. The analysis has been carried out by using numerical models for predicting and comparing the systems performances in terms of electric efficiency and capability in realizing the waste to energy and the electric energy storage of renewable sources. Results have highlighted that the electric efficiency is very high for all configurations (35-45%) and, thanks to the combination with the waste to energy technology, the storage efficiencies are very attractive (in the range 72-92%).
废物能源（WtE）设施和可再生能源储存系统在促进“生态创新”方面发挥着战略作用，这是欧盟新出现的优先事项。本文旨在提出先进的工厂配置，其中将废物能源工厂和间歇性可再生能源的电能储存系统相结合，以根据“生态创新”方法获得更高效、更清洁的能源解决方案。先进的工厂配置包括基于固体氧化物电解槽（SOEC）的电能储存（EES）部分、基于等离子体技术的废气化部分和基于固体氧化物燃料电池（SOFC）的发电部分。工厂配置的不同之处在于等离子体气化部分和发电部分中电解氢和氧的利用。在第一个工厂配置 IAPGFC（集成空气等离子体气化燃料电池）中，可再生氧丰富了空气流，该空气流用作气化部分的等离子体气体，可再生氢用于在发电部分中丰富 SOFC 的阳极流。在第二个工厂配置 IHPGFC（集成氢等离子体气化燃料电池）中，可再生氢用作等离子体气化部分的等离子体气体，可再生氧用于在发电部分中丰富 SOFC 的阴极流。分析是通过使用数值模型进行的，以预测和比较系统在电效率和实现废物能源和可再生能源电能存储能力方面的性能。结果表明，所有配置的电效率都非常高（35-45%），并且由于与废物能源技术的结合，存储效率非常有吸引力（在 72-92%范围内）。
