The leader of the Renewable Energy Research Group of the University of Pannonia Nagykanizsa, University Center for Circular Economy, participating in the Renewable Energy National Laboratory (NLRE) project, Dr. Nóra Hegedűsné Baranyai, pointed out the followings in her answer.
The NLRE project has provided outstanding professional and innovation support to the research group. As a result of the group's work within the framework of the program, two patents have been issued, several scientific papers have been published, and new domestic and international collaborations have been initiated. The project has helped the group's research results become more widely known and strengthen its role in the domestic development of renewable energy deployment.
The most important activity of the group in the program has been the research aimed at supporting solar power plant schedule keeping, in which they have modelled the conversion of excess energy from photovoltaic energy production (converting solar energy into electricity by the use of solar cells) into hydrogen via electrolysis. Three technologies (alkaline, proton exchange membrane and solid oxide) have been examined and compared in terms of technical feasibility and energy balance. The analysis contributes to the system-level integration of variable renewable energy sources and the promotion of the utilization of green hydrogen in Hungary.
