Born in 1970, Dr. Marnellos graduated the Dept. of Chemical Engineering at Aristotle University of Thessaloniki (AUTH) in 1995. He obtained his Ph.D. in 1999 from the AUTH, and a Master degree in Business Administration from the Macedonia University (Thessaloniki) in 1998. Since 2003, he is appointing an academic position (today as an Associate Prof.) in the Dept. of Mechanical Engineering at the University of Western Macedonia (UoWM - Kozani, Greece), and he is also an affiliated faculty member in the Chemical Process & Energy Resources Institute (CPERI) at the Centre for Research & Technology Hellas (CERTH).

 

He is the co-author of 50 papers in international scientific journals, 19 in international conference proceedings, 59 in national conference proceedings and 2 book chapters, concerning solid state electrochemistry, heterogeneous catalysis and biomass-to-energy science and engineering. He is also holding an international patent, which deals with the use of high temperature proton conducting membrane reactors for electro-catalytic ammonia synthesis at atmospheric pressure. In 2005, he established and currently leading the research group of Sustainable Technologies on Alternative & Renewable FUELS. STAR FUELSmission is to stimulate and conduct high-level fundamental and applied research in the fields of hydrogen (production, recovery and fuel cells), air pollution control (NOX, VOCs, etc) and biomass to energy conversion technologies. Based on his efforts for research and institutional funding, STAR FUEL was rapidly staffed and equipped with over 1 M€ of modern and high quality analytical infrastructure.

 

He had independently granted numerous research grants and industrial contracts, while during his Ph.D. and Post-Doctoral and also as a faculty member, he participated in extended European research consortiums. During his past and recent research activity, he had the opportunity to develop and expand a valuable network of collaborators both in Greece and abroad, including worldwide appreciated academic and research institutions and well-known companies.

 

Dr. Marnellos published work has been worldwide acknowledged with more than 570 citations (excluding self-citations), while special articles have been written by others in Journals’ and newspapers’ editorials referring to the novel method for ammonia synthesis. He is a regular reviewer in relevant scientific Journals and research funding agencies and he is/was a member in the organizing and scientific committees of international and national scientific conferences. In 2010, he obtained the Fulbright research scholarship to cooperate with MIT (Prof. Yang Shao Horn, Dept. of Mechanical Engineering) in the research field of fuel cells. Based on his activities in hydrogen production and fuel cells, he was appointed by the Greek Ministry of Development as a deputy coordinator of the Fuel Cells for Stationary & Mobile Applications working group of the Hellenic Hydrogen Platform and as a representative in one of the fuel cell actions operating at COST. He has also acted as an evaluator expert in the corresponding calls of FCH-JU. Finally, he is the Vice-Chairman of the Hellenic Society of Hydrogen Technologies and ex-Chairman of the Hellenic Association of Chemical Engineers.

RESEARCH ACHIEVEMENTS

Dr. Marnellos, either as a PhD candidate/Post-Doc or as a senior scientist, involved in a number of significant research contributions. Specifically, his research efforts have led to the following achievements:

1.      Electrochemical aided shift of equilibrium limited reactions – Dr. Marnellos first reported [Marnellos and Stoukides, Science 282 (1998) 98; Marnellos et al., J. Catal. 193 (2000) 80; Marnellos et al., Sol. St. Ionics 97 (1997) 375; etc] a new method based on H+ conducting solid electrolyte membrane reactors (SEMRs) to synthesize ammonia at atmospheric pressure bypassing the thermodynamic restrictions that limit equilibrium conversion. This pioneering work has opened new orisons for various similar chemical processes (CH3OH synthesis) as well as for the un-resolved problems arising during nitrogen fixation.

2.      Electrochemical promotion of reactions – Dr. Marnellos is still working on the electrochemical promotion of various industrially important chemical reactions (e.g. hydrocarbons partial oxidation/reforming and selective catalytic reduction of nitrogen oxides) in both O2- and H+ conducting SEMRs [Tsiakaras et al., Appl. Catal. A 169 (1998) 249; Pekridis et al., Catal. Today 127 (2007) 337; etc]. Especially, in the case of H+-SEMRs, pure Η2 can be produced and recovered in a single device minimizing the downstream treatment costs for purification.  

3.      NOX and N2O abatement using water as a hydrogen source – Dr. Marnellos developed a new concept to abate NOX and N2O to N2 using a double chamber H+-SEMR steam electrolysis cell [Kalimeri et al. Sol. St. Ionics 181 (2010) 223]. This advantageous simple and safe process does not require any storage or usage of extra reducing agent since the easily stored and abundant H2O is used as a H2 source. Moreover, as a side effect of steam electrolysis, pure O2 can be produced on the anode.

4.      Simultaneous reduction of NOX and N2O by hydrocarbons in excess oxygen – A dual bed catalytic reactor consisting of In/γ-Al2O3 and Ru/γ-Al2O3 was demonstrated [Marnellos et al., Ind. Eng Chem. Res. 43 (2004) 2413], in which high NOX (70%) and N2O (90%) conversions were achieved even under realistic conditions for long term operation, leading to new aspects for nitrogen oxides and hydrocarbons emissions reduction in the flue gases of power plants and automotive exhausts. 

5.      Classical vs electrochemical catalytic promotion – The well-defined rules of catalyst’s promotion described by Vayenas et al. (“Electrochemical Promotion of Catalysis”, Kluwer Eds. 2001) and the similarities existing between classical and electrochemical promotion, were verified also for N2O reduction reaction in potassium promoted Pd catalysts and electrodes [Pekridis et al., Sol. St. Ionics, 192 (2011) 653], where the promotional effects were attributed to the changes in the strength of reactants’ chemisorptive bonds.

6.      Direct hydro-carbon SOFCs – Recent research activities of Dr. Marnellos are devoted to the development of multi-component anodic composites based on Cu-M/CeO2 (M: a second metal), for direct hydrocarbon and carbon fed SOFCs. Promising results have been obtained in the case of carbon fed O2- -SOFCs, where power outputs similar to H2 fed SOFCs were achieved [Konsolakis et al., Proceeding of 6th Intl. Conference on Clean Coal Technlogies, 2013].

7.      SOFC integration in biomass thermochemical processes – STAR FUEL was one of the first teams that reported the integration of SOFCs to thermochemical and biological biomass conversion processes, where power can be produced at higher efficiencies exceeding those obtained in conventional thermal cycles [Athanasiou et al., Intl. Hydrogen Energy 32 (2007) 337].
