Dr. Panagiotis Grammelis, is the Director of Research at the Institute of Chemical Processes and Energy Resources of the Centre for Research and Technology Hellas (CERTH/CPERI). He has more than 25 years of experience in energy production and environmental issues, specializing in the utilization of alternative fuels and low-carbon energy technologies. He leads a Scientific Group (consisting of 60 scientists) with a key role in the Energy Transition Era and the decarbonization period at the local and national levels. He participates in the coordinating committee of ETIPBioenergy, the Biomass Panel of the RHC-ETP Platform (responsible for large biomass installations), and the committees of GSRI for the Environment and the Decarbonization of the Greek Economy. He is a member of the Editorial Board of international journals such as IJER, IJGW, and Energies Journal/Fuels, as well as the scientific committees of international conferences (GCGW, EUBCE, WSED). A notable example of his work is the H2-HUB (emblematic action in the Master Plan for the post-lignite era in Western Macedonia, funding of 19,8 m€), a flagship research project focused on applying hydrogen technologies in the value chain.

Dr. Dionysios Giannakopoulos, is a Senior Researcher at the National Center for Research and Technological Development / Institute of Chemical Processes and Energy Resources (CERTH/CPERI), Director of Quality at the Accredited Certification Body (Notified Body CE 0617) for hot water boilers (CE Marking), and Director of Quality at the Environmental Measurement Unit of the Steam Boilers and Thermal Systems Laboratory at the National Technical University of Athens. He has over 25 years of experience in clean technologies for utilizing solid fuels, analysis of technical and economic characteristics of electricity generation systems, strategies and measures for reducing CO₂ emissions, environmental management systems, combined heat and power systems, rational energy use, and strategies and measures for developing hydrogen and Fuel Cell technologies. He is a member of the Working Group of the Western Macedonia Region for the Preparation of the Transition to a Low Lignite Dependency Status within the EU’s Coal Regions in Transition Platform Initiative (2017-present).

Dr. Dimitrios-Sotirios Kourkoumbas, is a senior research engineer at CERTH/CPERI since 2011. He received his PhD from National Technical University of Athens (NTUA) in sustainability and circular economy sector. He is a Mechanical Engineer from NTUA with Master of Science in Energy Production and Management (NTUA). He is specialized in the simulation and development of LCA/LCC for integrated advanced energy systems. His basic scope of research is the sustainable management of energy resources in environmental, economic and social terms under the framework of a circular economy approach focusing mainly on advanced biomass exploitation technologies with emphasis in biogas/biomethane, RES and energy storage solutions, waste management, CO₂ utilization, design/development of solutions for smart factories and ecosystem restoration. In CERTH/CPERI, he leads the sustainability team and coordinates the activities in circular economy sector. He has participated as Senior Research Engineer and Senior Project Manager in EC and National funded project, as well as industrial projects.
