Development of Electrolyser Projects for Production of Renewable Hydrogen

Hydrogen is one of the important factors in reaching climate neutrality from the European Green Deal, particularly hydrogen made from renewable energy sources. The paper describes electrolysis plants in technical, environmental and regulatory aspects and presents obstacles that need to be overcome for the successful implementation of electrolyser projects, looking at the bigger picture of the energy sector. Part of the paper is dedicated to the research of existing projects and the plans for the development of electrolysers. Possible contribution of the development of electrolysis plants is in the application at the locations of existing thermal power plants that are no longer suitable for operation due to technological, economic or environmental reasons, which would take advantage of the existing location of the power plant for the installation of new technology that meets the concept of low-carbon development.
