/ Presentation

ENGIE is historical leader in gas marketing in France and is the first operator of gas infrastructure in Europe with a portfolio comprising transport networks, distribution networks and storage. ENGIE is a demonstrator of green hydrogen injection into the gas distribution network in France. It has contributed to the construction and maintenance of the hydrogen station for 100% hydrogen buses in the North of France.

/ Main tasks in RHeaDHy

ENGIE, laboratory CRIGEN, will provide its expertise in the development of Europe-wide hydrogen networks, to ensure the safety and sustainability of HRStations. As operator of future stations, ENGIE will carry out several tests during the development of the project.

/ Key people on the project


Reda Bellahcene, co-coordinator of RHeaDHy project, is double graduate from two institutions, the School of Engineering « Ecole Supérieure des Technologies Industrielles Avancées (ESTIA) » and the « Universidad Del Pais Vasco (UPV) ». Currently, he is actively engaged in the professional sphere, serving as a valuable member of ENGIE and contributing to the cutting-edge research conducted at the ENGIE Lab CRIGEN. Within this Research Center, he assumes a pivotal role in managing and coordinating various projects that span the entire hydrogen value chain.

In his capacity as a hydrogen project manager, Reda plays a role in fostering seamless collaboration among all project partners to ensure the successful and timely execution of every aspect of the RHeaDHy project.


Quentin Nouvelot, co-coordinator of RHeaDHy project, is the Deputy Head of the Hydrogen Lab at ENGIE Research Center. With extensive expertise in the hydrogen field, he oversees multiple research programs focused on crucial topics such as H2 Mobility, safety, and H2 quality. Quentin is recognized as an expert and actively contributes to the development of ISO standards on hydrogen within the ISO TC 197, particularly in the area of hydrogen refueling protocols.

Prior to his current role, Quentin successfully managed ENGIE’s involvement in various European research projects. Notably, he played a key role in the PRHYDE project, which focused on developing heavy-duty refueling protocols. His leadership and contributions have been assets for advancing ENGIE’s presence and impact within the hydrogen industry.


Thomas Guewouo, PhD, is a Research Engineer at ENGIE Research Center. He has significant expertise in the modelling and optimization of energy systems. Thus, he is developing simulation and optimisation tools for blocks or systems in the hydrogen value chain; from production to use, including transport and storage. Thomas is also an expert on ISO TC197 and contributes to the development of ISO standards on hydrogen refuelling protocols and on connection devices for gaseous hydrogen land vehicles refuelling.

As leader of the work package on the implementation of new refuelling protocols for heavy-duty vehicles, Thomas’ role in the RHeaDHy project will be to help ensure the success of all project tasks through simulations. He will contribute to the use of the results of RHeaDHy project by ISO in the development of new protocols and the standardization of connection devices for hydrogen high flow refuelling lines.


After studying mechanical and energy engineering, Dorine Crouslé began to work at ENGIE Lab CRIGEN. Her job aims at developing low-carbon heavy duty mobility, by understanding and improving hydrogen refuelling stations.

In RHeaDHy project, she will try to ensure that the components developed will satisfy the objectives once assembled together by adopting a global point of view and by running simulations.


Nicola Benvenuti is a PhD student currently conducting his thesis at ENGIE Lab CRIGEN in collaboration with IMT Mines Albi-Carmaux. The main objective of his thesis is to build a model capable of predicting the performances of hydrogen refuelling stations.

Thus, his main contribution to the RHeaDHy project is to assist the design and testing of the fuelling line for heavy duty application by providing insight on the system thermodynamic behaviour. Nicola is honoured of being part of this ambitious project that will represent an important step towards transport decarbonisation in Europe.
