HyCoFlex Project

HyCoFlex at #ECOS2026! This week, Nikos Skordoulias and Sotirios Karellas represented the HyCoFlex project at ECOS 2026 – the 39th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems, where they delivered an oral presentation entitled: "Optimised sizing and operational dispatch of grid connected PEM electrolysers for hydrogen-fired gas turbines using a multi-objective framework: A HyCoFlex case study." The presentation showcased a novel multi-objective optimisation framework that simultaneously determines the optimal sizing and operational dispatch of grid-connected PEM electrolysers supplying hydrogen to an advanced hydrogen-fired gas turbine. Using the HyCoFlex pilot-scale facility as a case study, the research demonstrated how integrated system design and operation can identify cost-effective pathways for renewable hydrogen production. The results highlighted optimal electrolyser capacities for different hydrogen demand scenarios while achieving competitive Levelised Costs of Hydrogen (LCOH) and complying with RFNBO carbon-intensity criteria. Thank you to the organisers of ECOS 2026 for bringing together researchers and industry experts to exchange ideas on the future of sustainable energy systems. We also thank everyone who attended the presentation and contributed to the engaging discussions. Learn more about the conference: https://ecos2026.insae.ro/

It was great to present the paper at ECOS2026. A lot of interesting questions and discussion came out after the presentation. Great work and many thanks especially to Nikos Skordoulias and Ertan Yilmaz and of course to the whole HyCoFlex Project consortium.!

🚛 #HyCoFlex takes a major step toward its 2026 demonstration campaign   The HyCoFlex project’s SGT-400 high-H₂ gas turbine has arrived at the ENGIE Energie Services cogeneration plant, bringing the project one step closer to its 2026 testing campaign.   Following successful testing with natural gas at Siemens Energy’s facility in Lincoln, UK, Centrax Gas Turbines has transported the unit to the demonstration site at Smurfit Westrock’s industrial paper production plant in Saillat-sur-Vienne, France.   This marks the transition from development, manufacturing, and component validation to preparation for the upcoming hydrogen-focused testing phase of the integrated power-to-H₂-to-power concept.   Successfully achieving this milestone on schedule reflects the strong collaboration and coordinated efforts of all project partners. Installation activities are now underway at the plant — stay tuned as the project moves closer to the first fire of the demonstration campaign.   🤝 A big thank you to all #HyCoFlex partners for making this milestone possible.   #HyCoFlex #Hydrogen #CleanEnergy #EnergyTransition #Decarbonization #IndustrialDecarbonization #GreenHydrogen #PowerGeneration #GasTurbine #Cogeneration #Sustainability

🌍⚡ Can existing cogeneration plants become part of a hydrogen-powered future? At HyCoFlex, we believe they can. The project is developing a retrofittable decarbonisation solution that enables industrial combined heat and power (CHP) plants to operate with up to 100% renewable hydrogen, helping industries reduce emissions while maintaining reliable energy production. Building on the achievements of the HYFLEXPOWER project, HyCoFlex is focused on: ✅ Upgrading industrial cogeneration infrastructure for safe and efficient hydrogen operation ✅ Developing advanced low-emission hydrogen combustion technology for gas turbines ✅ Demonstrating flexible operation under different hydrogen and natural gas fuel mixtures ✅ Creating digital tools and pathways that support the replication and scaling of hydrogen retrofits across Europe By validating these solutions at the industrial site in Saillat-sur-Vienne, France, the project aims to accelerate the transition towards a more flexible, resilient and low-carbon energy system. Hydrogen is not only a fuel of the future—it is becoming a practical pathway for decarbonising industrial power generation today.

🚀 Introducing HyCoFlex – Hydrogen for Cogeneration in Flexible Operation How can existing industrial cogeneration plants be transformed into low-carbon energy systems without replacing their entire infrastructure? The #HyCoFlex project is tackling this challenge by developing a retrofittable hydrogen-based solution that enables gas turbines to operate with up to 100% renewable hydrogen. Building on the achievements of the HYFLEXPOWER project, HyCoFlex is advancing power-to-hydrogen-to-power technology to support the decarbonisation of industry and energy generation. In HyCoFlex, 11 partners from 7 countries work together to: ✅ Upgrade industrial cogeneration systems for hydrogen operation ✅ Develop and validate advanced low-emission hydrogen combustion technology ✅ Demonstrate flexible operation with varying hydrogen-natural gas blends, up to 100% hydrogen ✅ Create pathways for scaling and replicating hydrogen-based solutions across Europe   By enhancing operational flexibility, reducing emissions, and supporting industrial decarbonisation, HyCoFlex is helping pave the way towards a cleaner and more resilient energy future. 🌍⚡   Follow our journey as we move from innovation to large-scale demonstration and unlock the potential of hydrogen for sustainable power and heat generation. #HyCoFlex #Hydrogen #CleanHydrogen #Decarbonisation #EnergyTransition #Cogeneration #Innovation #HorizonEurope #SustainableIndustry
