Mateusz Szubel (PhD, Eng.), assistant professor at the AGH University of Science and Technology, Faculty of Energy and Fuels, Krakow, Poland. Professor Szubel is a member of the research group focused on the issues of renewable energy technologies, at the Department of Sustainable Energy Development. He is a research specialist on the conditions for the sustainable energy development. Furthermore, he is involved in the investigation of the possibilities of involving computational fluid dynamics (CFD) in the optimization of renewable energy technologies and increasing the energy efficiency of energy systems. He is focused on numerical modeling of energy storage and biomass thermochemical treatment. For 12 years professor Szubel has been running over 20 academic courses related to the practical aspects of renewable energy technologies’ applications and the use of commercial CFD codes to analyze the elements of these systems. He is author and coauthor of 120 scientific and popular science papers. Mariusz Filipowicz (DSc, Eng.), associate professor at the AGH University of Science and Technology, Faculty of Energy and Fuels, and former head of the Department of Sustainable Energy Development, Krakow, Poland. Professor Filipowicz graduated with an MSc in Technical Physics in 1991, obtained a PhD in 1998, and did habilitation in 2010 in the field of nuclear physics–nuclear fusion catalyzed by negative muons. Between 1994–1995, he completed a postgraduate course in Energy and Environment, the Tempus-Joint European Project (JEP) Postgraduate Course on Energy and Environment. Professor Filipowicz’s main research areas are related to renewable energy technologies (mainly biomass, solar, and wind energy applications), energy efficiency, and nuclear physics (nuclear fusion reactions in the range of ultra-low energy). He is author and coauthor of more than 250 scientific papers and leader of scientific projects at AGH, such as, ""BioEcoMatic: Construction of small-to-medium capacity boilers for clean and efficient combustion of biomass for heating"" and ""BioORC: Construction of cogeneration system with small to medium size biomass boilers"" with the support of KIC InnoEnergy. Karolina Papis-Frączek (MSc., PhD student), academic teacher and research assistant at the AGH University of Science and Technology, Faculty of Energy and Fuels, Krakow, Poland.
