Wind and sun will be central energy sources of a climate neutral Europe 2050, bringing with them the need to balance weather dependent differences between supply and load. Conventional gas turbines can fulfill this task also for longer periods even well as they can stabilize the grid with their capability of quick start/stop. However, their efficiency is limited and – even if burning climate neutral hydrocarbons – they still produce local emissions. HERMES overcomes these limitations and advances gas turbine technology to the future-proof level by creating a reliable, flexible, zero-emission solution for energy supply with long term impact at EU level. HERMES develops and assesses the first highly efficient closed-loop supercritical zero emission energy system. It is based on directly fired supercritical gas turbine engine operating on locally synthesized renewable liquid and gaseous fuels (e.g. methanol or hydrogen) coupled with decentralized carbon capture utilization and storage (CCUS). The carrier medium is highly dense supercritical carbon dioxide or xenon demanding less compression power. Therefore, and because of operating at high pressure conditions (above 150 bar), the system achieves significantly higher efficiency (above 65%) than today’s gas turbines. By utilizing pure oxygen for fuel oxidation, and by capturing bulky flow of exhaust products (H2O and/or CO2) and reusing them for fuel synthesis, the system produces virtually no pollutants. A detailed assessment of the HERMES approach will be done using experimental and computational approaches and dynamic simulation tools including digital twins and machine learning. The 36-month project will be realized by an 11-partner consortium including 3 SMEs with expertise in renewable energy, combustion, techno-economics and socio-political science. Hermes will pave the way to a major breakthrough in the understanding of fundamentals of combustion in supercritical fluids with zero emission of any pollutants.

风能和太阳能将成为2050年欧洲气候中立的主要能源来源，因此需要平衡供应和负荷之间的天气差异。传统的燃气轮机由于其快速启动/停止的能力可以稳定电网，因此也可以在更长的时间内完成这项任务。然而，它们的效率是有限的，而且——即使燃烧对气候无害的碳氢化合物——它们仍然会产生局部排放。HERMES克服了这些限制，并通过创造可靠、灵活、零排放的解决方案，为欧盟层面的能源供应提供了长期影响，将燃气轮机技术提升到面向未来的水平。HERMES开发并评估了首个高效闭环超临界零排放能源系统。它基于直接燃烧的超临界燃气涡轮发动机，使用当地合成的可再生液体和气体燃料（例如甲醇或氢气），加上分散的碳捕获利用和储存（CCUS）。载体介质为高密度的超临界二氧化碳或氙，对压缩功率要求较低。因此，由于在高压条件下（高于150 bar）运行，该系统比当今的燃气轮机实现了显着更高的效率（高于65%）。通过利用纯氧进行燃料氧化，并捕获大量废气（H2O和/或CO2）并将其重新用于燃料合成，该系统几乎不会产生任何污染物。对HERMES方法的详细评估将使用实验和计算方法以及动态模拟工具，包括数字双胞胎和机器学习。这个为期36个月的项目将由11个合作伙伴组成，其中包括3家在可再生能源、燃烧、技术经济学和社会政治科学方面具有专长的中小企业。Hermes将为理解零排放任何污染物的超临界流体燃烧的基本原理铺平道路。
