Autonomous underwater robots, particularly ocean gliders, are playing a crucial role in ocean exploration, collecting data on various environmental parameters. However, the reliance on lithium batteries has posed challenges due to safety regulations and costs associated with their transportation. To overcome this hurdle, scientists at the Helmholtz-Zentrum Hereon have introduced a revolutionary energy system utilizing hydrogen as a clean and sustainable alternative. The system, developed by Dr. Lucas Merckelbach and Dr. Prokopios Georgopanos, employs membrane technology inspired by nature to extract oxygen from seawater, resembling a fish's gills. By utilizing a fuel cell powered by hydrogen and oxygen, the gliders can operate without the need for onboard oxygen storage, leading to increased energy density and reduced operating costs. The team has patented this innovative system and is working on further enhancements through the MUSE project, in collaboration with other research institutions. This interdisciplinary effort combines expertise in coastal research, membrane technology, and hydrogen applications to pave the way for more efficient and environmentally friendly underwater exploration.
