Sofia Galeotti (Univ. of Florence) and Mario Di Taranto (SINTEF) presented the latest results from the TRANSITION Project at the 12th IGTC arranged by ETN Global on 14-15th October 2025, in Brussels. In the project, a Baker Hughes burner is being upgraded to include hydrogen piloting such as to withstand a higher grade of exhaust gas recirculation (EGR) in the gas turbine. As a result, CO2 capture from the combined gas turbine power plant can be improved through gains in both energy efficiency and capture plant equipment size. While the former lowers operational costs, the latter capital costs, both being major barriers to the deployment of Carbon Capture and Storage (CCS) as a climate change mitigation technology.

Three technical papers were presented by UNIFI and BH at ASME Turbo Expo 2025 in Memphis, Tennessee (USA), June 16–20, 2025: “Impact of Fuel Injection System on the Performance of an Industrial Burner With Hydrogen Piloting Operated With Simulated Exhaust Gas Recirculation”; “High Fidelity Simulation for the Flame Extinction Analysis of an Industrial Burner Operated With Artificial Egr” and “Modulation of the Thickened Flame Model into Eddy Dissipation Concept for Multi-Regime Combustion Modelling”

UNIFI presented the work "Hybridization of the Eddy Dissipation Concept with the Thickened Flame Model for High-Fidelity Multi-Regime Combustion Simulations" during the 12th European Combustion Meeting, April 7-10, 2025, Edinburgh, Scotland, UK

SINTEF (Elettra Vantaggiato) presented part of the work from TRANSITION in the 17th International Conference on Greenhouse Gas Control Technologies GHGT-17, 20th -24th October 2024, Calgary Canada. The poster presentation was a synergistic effort with the project CleanOFF Hub, CleanOFF Hub - SINTEF.

Transition project was well represented at ASME Turbo Expo 2024 (June 24–28, 2024, London, UK): 4 technical papers were presented by UNIFI, SINTEF and BH: “Prediction of the Flame Characteristics of an Industrial Gas Turbine Operated With CO2-Diluted Air Through an LES-Based CFD Analysis: A Comparison Between FGM and ATF", “Experimental Study on Stability Enhancement of a Natural Gas GT Burner With Hydrogen Flame Piloting Operated With Simulated Exhaust Gas Recirculation”, "Understanding the Potential and the Challenges of a NGCC Integrated With Hydrogen-Assisted EGR and CO2 Capture", “Thickened Flame Model Extension for Dual Gas GT Combustion: Validation Against Single Cup Atmospheric Test".

Also a panel session titled "Carbon Capture and Exhaust Gas Recirculation: Challenges and Opportunities for a Gas Turbine Decarbonization Pathway" was organized.
Organizers: Prof. A. Andreini (UNIFI), Prof. J. O’Connor (Penn State, USA)
Panelist: J. Duckers (Solar Turbines), E. Vantaggiato (SINTEF), P. Kulkarni (GE Vernova), R. Meloni (Baker Hughes)

UNIFI presented two works at the 46th Meeting of the Italian Section of The Combustion Institute (ASICI), June 2-5, 2024, Bari, Italy: "Lean blow-out analysis for the performance assessment of different burner designs through a high-fidelity CFD approach"; "Experimental and numerical study of the effect of co2/n2 dilution to simulate egr in gt combustor".

Picchi, S. Galeotti, R. Becchi, A. Andreini, G. Babazzi, R. Meloni), during the Joint Meeting of the Belgian and Italian Sections of The Combustion Institute, “Combustion for Energy Transition and Sustainable Mobility” – 45th Meeting of the Italian Section of the Combustion Institute, held in Florence from 28 to 31 of May, 2023

TRANSITION project was mentioned in SINTEF blog: How hydrogen can enhance CO₂ capture in natural gas power plants. Combining exhaust gas recirculation (EGR) with a touch of hydrogen can boost CO₂ capture and cut costs.  https://blog.sintef.com/energy/hydrogen-enhance-co2-capture-natural-gas-power-plants/

UNIFI MAGAZINE published an Interview to Antonio Andreini: “Unifi designs the gas turbine of the future – TRANSITION project, funded under Horizon Europe, aims to develop a new type of burner that is more efficient and less onerous on the environment” https://www.unifimagazine.it/turbina-gas-co2/
