Power Electronics Role in Future Hydrogen Systems-Slides

Abstract: Decarbonization of major energy-consuming sectors is a top priority of the 2015 Paris Agreement and the Intergovernmental Panel on Climate Change (IPCC) climate change 2023 report. This has significantly challenged today's energy systems with the development of long-term sustainable energy production and storage. Perhaps one of the most promising strategies for addressing this challenge is the implementation of hydrogen solutions, in which renewables can be heavily utilized and new ways of storing and transporting this green energy can be followed. These are seen to be a solution for many sectors, including so-called hard-to-abate areas in which it can be used as a feedstock or directly as a fuel. In this context, power electronics is expected to play a key role in enhancing the performance and reducing the final product cost of such systems, where different systems are expected to be integrated together, e.g. different types of renewables to feed a cluster of electrolyzers for hydrogen production, with potentially a grid connection, where grid support might be a possible option as well. Moreover, electrolyzers and fuel cells, as key elements in such hydrogen systems, are low-voltage high-power elements, where their voltage varies significantly under different loading conditions and over lifetime. Therefore, the utilized power converters must ensure high performance over a wide range of operation from beginning to end of life, while meeting the requirements on the source or load side. Hence, this webinar is aimed at discussing this role of power electronics in future electrified hydrogen systems and giving more insights in this area.
