Mikaa Blugeon-Mered is a senior researcher on hydrogen strategies and geopolitics. He also advises local governments and SMEs on H2 markets and policies, contributes to several leading international hydrogen bodies (World Bank, IHFCA, CertifHy…) and is the founder of “Hydrogen Mosaic”, an educational innovation studio producing public-oriented games to spread hydrogen scientific knowledge.

Entrepreneur with 30 years in industry, in various sectors including automotive and energy, in positions of responsibility ranging from managing major international projects in large groups to general management of SMEs, and having founded CLHYNN in 2022 with a CNRS researcher to propose decentralised electricity production for mobility or stationary use, a genuine third way that is more sustainable, sovereign and practical than batteries and conventional hydrogen

Johann Lejosne holds a PhD in electrochemistry and has recognized expertise in renewable energy technologies. He began his career as a project manager with the Bolloré Group, before joining CEA Grenoble, where he spent twelve years in strategic roles including large-scale project management, leadership of multidisciplinary teams, development of technological platforms, and business development—primarily in the fields of lithium-ion batteries and hydrogen fuel cells.

Since June 2022, he has been serving as Director of Sales and Partnerships for Energy Transition at INOCEL, an innovative company specialized in the development and industrialization of high-power fuel cells. INOCEL designs, manufactures, and markets modular solutions that integrate the fuel cell system, cooling system, and power conversion within high-power containerized units—providing clients with plug-and-play solutions to accelerate their energy transition.

After founding two companies in the energy storage industry, Sébastien Le Pollès established FlexFuel Energy Development (FFED) in 2009, an innovative French SME in the green energy sector specializing in systems that reduce fuel consumption and pollutant emissions from internal combustion engines.

From late 2016 to December 2020, leveraging FFED’s recognized expertise in ecological engine depollution through hydrogen injection, he invested in an R&D program for the French Defence Procurement Agency (DGA) in partnership with the Pôle Mer Méditerranée to develop and optimize a mobile unit for cleaning and maintaining high-powered engines of both civilian and military vessels.

A pioneer and market leader in Superethanol-E85 conversion kits, Sébastien Le Pollès contributed his expertise to the drafting and publication, in late 2017, of a ministerial decree by the Ministry for the Ecological and Inclusive Transition and the Ministry of the Interior, which authorized the approval and installation of these conversion systems.

In 2020 and again in 2021, FFED was selected by the French government to join the French Tech 120 program.

The partnership with the DGA also enabled him to develop a breakthrough Anion Exchange Membrane (AEM) technology, deployed through Gen-Hy, a spin-off from FFED founded in 2019. Through Gen-Hy, Sébastien Le Pollès expanded into the manufacturing of electrolyzers for green hydrogen production, incorporating his AEM technology. His ambition is to contribute to the emergence of a fully French hydrogen technology sector.

In April, as part of the Important Project of Common European Interest (IPCEI) Hydrogen program, Gen-Hy was awarded €100 million by the French government to build in Bourgogne-Franche-Comté the first French factory dedicated to AEM membranes and electrolyzers for green hydrogen production.

Guillaume Malot is the HSE and Crisis Management Manager at ENGIE Hydrogen Solutions. He oversees the safety of people and property on hydrogen projects at the national level. Active in the industry and within the ENGIE group, he shares his experience and contributes to common standards. A specialist in ATEX risks and Safety Instrumented Systems, Guillaume Malot works across the entire value chain, from feasibility to operation.

Yannick Monnier currently serves as Director at the Régie des Transports du Territoire de Belfort (RTTB), operator of the Optymo urban network, where he oversees the development and management of public transport across the Belfort metropolitan area. His nearly twenty years of involvement with RTTB have given him an in-depth understanding of the operational and strategic challenges of urban mobility, particularly regarding emerging technologies and the sector’s energy transition.

Before being appointed Director in December 2014, Yannick Monnier first held the position of Deputy Director (2013–2014), as well as Head of IT and Projects (2005–2012), where he was notably responsible for the implementation and monitoring of onboard systems and R&D for the Optymo network, with a focus on intelligent transport systems. This experience enabled him to master the integration of complex technological solutions, the supervision of innovative projects, and the implementation of measures aimed at improving safety, performance, and risk management within public transport networks.

An engineer by training with over 15 years of industry experience, Emmanuel Perdriset leads the development of Lhyfe’s activities in the North-East quarter of France. Lhyfe develops, builds, and operates green and renewable hydrogen production sites across Europe. With 21 MW of installed and RFNBO-certified capacity in France and a fleet of 70 trucks, Lhyfe distributes this hydrogen nationwide, serving both mobility and industrial applications.

Raphael Pourret is Strategy, Marketing and Communications Director, Hydrogen Solutions division, FORVIA Group. Educated engineer, Raphael began his career in the automotive industry in 2000. He held various positions in product development at Robert Bosch -Diesel Systems, Volvo Powertrain and then joined FORVIA’s Clean Mobility business in 2015. Raphael took over responsibility for the Strategy and Product Line for Faurecia Clean Mobility’s Commercial Vehicles segment in 2020, then joined the hydrogen business in July 2023.Raphaël is a Mechanical Engineer with a degree from Polytech Lyon.

An engineer by training with 25 years of industry experience, Stéphane Rabatel worked for nearly 10 years at Renault on electrification and contributed to innovative projects such as the Mégane E-Tech. He also held positions at Airbus and Safran before heading up a company specializing in fuel cell technology in 2022. Since 2024, he has been CEO of Hopium, which he is repositioning to supply fuel cells for heavy-duty mobility, maritime, and aerospace applications.

In March 2020, I joined Hynamics, EDF’s subsidiary dedicated to the production and distribution of low-carbon hydrogen for mobility and industry. After graduating from a general engineering school specialized in industrial risk management, I began my career in a consulting firm subsidiary of the Airbus group, then worked for ten years in process engineering and industrial safety in the oil and gas sector. Since January 2024, I am the head of the Engineering and HSEQ department, I supervise activities throughout all phases of project development, from design to operation, in order to ensure the implementation of best engineering practices and guarantee the performance and safety of our facilities.

Benno Weinberger is an expert in hydrogen safety and regulation. With a PhD in process engineering from the University of Paris XIII, he has been R&D manager at Ineris since 2009, where he leads work on H₂ risk analysis, provides ATEX and hydrogen safety training, and participates in several working groups on French hydrogen regulations. He is also involved in national and European research projects on hydrogen safety, and contributes to standardisation in groups such as AFNOR E29D, CEN CENELEC JTC 6, CEN 286 and ISO 197.
