Decarbonising the energy sector: ARTTIC is a partnering in newly launched FLEX4H2 project

The FLEX4H2 project aims at moving technological frontiers for low-emission combustion of hydrogen beyond the latest state-of-the-art

The “FLEX4H2” project – Flexibility for Hydrogen – officially started on 1 January 2023. The project, led by Ansaldo Energia, is jointly funded by the EU Horizon Europe Research and Innovation Framework Programme under the Clean Hydrogen Partnership (GA No. 101101427) and the Swiss Federal Department of Economic Affairs, Education and Research, State Secretariat for Education, Research and Innovation (SERI). FLEX4H2 has an overall budget of approximately EUR 8.7m and will run for four years, between January 2023 and December 2026.

FLEX4H2’s goal is to support European ambitious climate targets towards shifting away from the use of fossil fuels. In this context, utilisation of hydrogen offers a unique chance to decarbonise the power generation sector reliably, independently from weather or seasonal conditions, contributing to the ongoing effort in the fight against climate change, enabling_CO2-free, dispatchable power generation.

ARTTIC Innovation supports the Coordinator Ansaldo Energia in the daily administrative business. In addition, ARTTIC Innovation is involved in the project’s stakeholder engagement strategies, addressing EU policies and EU transformation towards decarbonisation. Finally, ARTTIC Innovation will be active regarding the development of a technology roadmap and support the exploitation of the project results.

FLEX4H2 aims to develop a fuel-flexible combustion system and will contribute to the EU Green Deal towards decarbonisation of the electric power sector

The aforementioned goal translates into the project’s main objective – to design, develop and validate a safe, efficient and highly fuel-flexible combustion system capable of operating with any concentration of hydrogen blend up to 100% _H2. Crucially, this objective will be pursued at the most challenging hydrogen combustion conditions, i.e., at H-Class operating temperatures, required for highest cycle efficiency, while still meeting emission targets without any use of diluents. The design of the combustor will be based on Ansaldo Energia’s Constant Pressure Sequential Combustion technology (CPSC) and will be demonstrated in a stepwise approach, at full gas turbine operating conditions (TRL6).

“Decarbonization of gas turbine assets is a fundamental part in the transition of the energy landscape. Only one engine, equipped with the novel FLEX4H2 combustion system, has the potential of eliminating up to 2,000,000t_CO2 emissions per year, whilst delivering enough clean energy to supply up to 500,000 households,” Federico Bonzani, Director Product and Technology at Ansaldo Energia stated.

The new, improved combustor design will be fully retrofittable to existing gas turbines, thereby providing significant opportunities for refurbishing existing assets. Furthermore, FLEX4H2 will present credible pathways for comprehensive exploitation of the project’s results and (thereby) provide the basis for a firm contribution to the EU Green Deal towards decarbonisation of the electric power sector by 2030 and beyond.

A strong European Partnership

The FLEX4H2 consortium includes nine partners from six European countries: Ansaldo Energia (IT), Arttic Innovation (DE), Centre Européenne de Recherche et de Formation Avancée en Calcul Scientifique – CERFACS (FR), German Aerospace Center – DLR (DE), Edison (IT), ETN Global (BE), SINTEF Energi (NO), Ansaldo Energia Switzerland (CH), Zurich University of Applied Sciences – ZHAW (CH).
