Store Electricity and Heat for Climate Neutral Europe

SEHRENE的新电热储能(ETES)概念旨在储存可再生电力(RE)和热量，并根据需要进行恢复。它非常节能(80%-85%)，不受地域限制，不使用关键原材料。它可以实现比Li-ion长8-12倍的存储时间，LCOS为80-137欧元/兆瓦时，具体取决于使用案例。这一价格低于成本最低的商用蓄电所--抽水蓄能。它的寿命为20-30年，是锂离子的2-3倍。将交付一个TRL4原型和3个完整使用案例的数字双胞胎：(I)陶瓷厂，将过剩的现场光伏发电和工业废热储存在微电网中，用于持续的绿色氢气生产和自我消费，(Ii)智能电网，和(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90kWh/m~3(+30%)的新型热能存储系统，在新型金属开尔文泡沫塑料中包含相变材料，以及(Iii)具有新型运行参数的ORC。新的数字工具将优化存储的能源管理，并促进潜在最终用户的投资决策，同时考虑到生命周期评估和技术经济因素。SEHRENE联合了5个研发团队，他们在热电系统的原型、基于物理的建模、表征和数字孪生兄弟、热存储和基于人工智能的能源管理方面拥有顶级专业知识；1个RE生产商、1个DSO、1个陶瓷公司、1个中小企业开发决策支持工具，以及1个负责传播和沟通的中小企业。开发计划旨在于2029年在第一家工厂实施该解决方案。SEHRENE的市场渗透率将使其能够在2040年之前获得1%的市场份额，每年避免9000万立方米天然气和1500万吨二氧化碳。研发和工业合作伙伴预计，到2035年，热泵、热储、ORC、研发成果许可证和咨询服务的销售将产生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 toplevel 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.
