The fifth Laser Colloquium Hydrogen (LKH2) organized by the Fraunhofer Institute for Laser Technology ILT will take place in Aachen on September 10 and 11, 2024. The event aims to promote sustainable networking and collaboration among experts from industry and research to address the inefficiencies in hydrogen production processes. A key highlight will be the presentation of the German-Australian HyGATE project, focusing on achieving cost-effective green hydrogen production. Dr. Alexander Olowinsky emphasizes the importance of increasing the efficiency of hydrogen processes through innovative laser technologies. The HyGATE project showcases a capillary electrolyzer with a high system efficiency of 95%, exceeding IRENA's targets for 2050. The collaboration between Germany and Australia in the HyGATE initiative aims to establish the first sustainable hydrogen supply chain. Presentations at the event will cover various topics, including laser-based processes for metal foam electrodes, laser microwelding of bipolar plates, and the production of laser-induced nanofoams. Participants will also have the opportunity to explore the state of research during laboratory tours at the HydrogenLab, which focuses on optimizing fuel cell production using laser technology. Dr. Olowinsky underlines that laser technology plays a crucial role in enhancing the efficiency of hydrogen production processes, highlighting its significance in advancing sustainable hydrogen solutions.
