Research / Laboratory

The research group is active in a wide range of applications related to: (a) the environmental impacts of energy production and use, (b) the renewable and alternative energy sources and (c) the development/evaluation of innovative energy materials/devices/systems. Subjects such as electrochemical engineering (solid oxide fuel/electrolysis cells, electrochemical reactors), heterogeneous catalysis (H2 production, CO2 hydrogenation, VOCs abatement, DeNOX), solid fuels thermochemical processes (pyrolysis and gasification), surface science, materials science & engineering, process system engineering & optimization are at the forefront of research group interests.

 

Curriculum Vitae

Research activities are focusing in the fields of hydrocarbons processing (natural gas valorisation, production of olefins), hydrogen (iso-octane and bioethanol reforming, steam and H2S electrolysis, electrochemical membrane reactors for hydrogen generation and separation) and fuel cell (direct hydrocarbon and solid carbon high temperature ceramic fuel cells) technologies, CO2 utilization (hydrogenation to methanol and methane, electrolysis toward CO), air pollution control (NOX, VOCs, etc) and biomass to energy conversion technologies (pyrolysis and gasification of solid biomass and biochars). His scientific work has been published in 75 articles in international journals and in >110 articles in scientific conferences with more than 1300 citations (H = 20 – Scopus). Prof. Marnellos has participated in extended research consortiums and has been the scientific coordinator in several National/EU research grants, while he is experienced in the supervision of PhD students (10) and Post-Doc (8) researchers. He is a regular reviewer in relevant scientific Journals and research funding agencies. In 2010, he obtained the Fulbright research scholarship to cooperate with MIT in the research field of fuel cells. In November 2015, he was awarded by the University of Western Macedonia a prize for Innovative Research in 2012-2014. He is currently the Chairman of the Cluster of Bioenergy and Environment in Western Macedonia.
