Store Electricity and Heat foR climatE Neutral Europe (SEHRENE)

SEHRENE的新电热储能（ETES）概念旨在存储可再生电力（RE）和热量，并根据需要进行恢复。它非常节能（80-85%），地理独立，不使用关键原材料。它的存储时间是锂离子电池的8-12倍，LCOS为80 - 137欧元/兆瓦时，具体取决于使用情况。这比抽水蓄能要低，抽水蓄能是成本最低的商业电力储存。其寿命为20-30年，比锂离子长2 -3倍。TRL4原型和3个完整用例的数字孪生体将交付：(i)陶瓷工厂在微电网中存储多余的现场光伏电力和工业废热，用于连续的绿色H2生产和自用，（ii）智能电网，（iii）地热发电厂。ETES集成了：(i)性能系数为理论最大值50%的新型热泵设计，（ii）能量密度为90 kWh/m3（+30%）的新型储热系统，在新型金属开尔文电池样泡沫中含有相变材料，（iii）具有新型操作参数的ORC。新的数字工具将优化储能系统的能源管理，并促进潜在终端用户将LCA和技术经济因素考虑在内的投资决策。SEHRENE联合了5个研发团队，在原型设计、基于物理的建模、热电系统的表征和数字孪生、热存储和基于人工智能的能源管理方面具有顶级的专业知识；1家稀土生产商，1家DSO， 1家陶瓷公司，1家开发决策支持工具的中小企业，1家传播沟通的中小企业。开发计划旨在2029年在第一家工厂实施该解决方案。到2040年，SEHRENE的市场渗透率将占据1%的市场份额，每年可减少9000万吨天然气和1500万吨二氧化碳。研发和工业合作伙伴计划到2035年从热泵、储热、ORC、研发成果许可和咨询服务的销售中产生580万欧元的收入

SEHRENE’s new electrothermal energy storage (ETES) concept is designed to store renewable electricity (RE) and heat and to restitute it as needed. It is very energy-efficient (80-85%), is geographically independant and uses no critical raw materials. It enables 8-12 times longer storage duration than Li-ion, with LCOS of 80 – 137 €/MWh, depending on the use-case. This is lower than pumped hydro, the lowest-cost commercial electricity storage. Its lifetime of 20-30 years is 2 – 3x longer than Li-ion. A TRL4 prototype and the digital twins of 3 full use-cases will be delivered: (i) ceramics plant storing excess, on-site PV power in a micro-grid and industrial waste-heat for continuous green H2 production and self-consumption, (ii) a smart-grid, and (iii) a geothermal power plant. The ETES integrates: (i) a novel heat-pump design with a coefficient of performance of 50% the theoretical maximum, (ii) a novel thermal energy storage system with energy density of 90 kWh/m3 (+30%), containing phase-change material in a novel metallic Kelvin cells-like foam and (iii) ORC with novel operating parameters. New digital tools will optimise the energy management of the storage and facilitate investment decisions by potential end-users taking LCA and technico-economic factors into account. SEHRENE unites 5 R&D teams with top level expertise in prototyping, physics-based modelling, characterisation and digital twins of thermo-electric systems, thermal storage and AI-based energy-management; 1 RE producer, 1 DSO, 1 ceramics company, 1 SME developing decision-support tools, and 1 SME for dissemination and communication. The exploitation plan aims to implement the solution in the first factory in 2029. SEHRENE’s market penetration will enable to capture 1% of the market by 2040 avoiding 90Mm3 of NG and 15Mt CO2/year. R&D and industrial partners project to generate 5.8M€ in revenues by 2035 from sales of heat pumps, thermal storage, ORC, licenses to R&D results and consulting services
