Classification society Lloyd’s Register (LR) has approved Corvus Energy's marine battery system, the Dolphin NxtGen Energy, indicating compliance with safety and regulatory standards. Corvus Energy emphasizes the system's lightweight, modular design that optimizes onboard space for hybrid-electric and fully electric marine applications, suitable for ferries, yachts, and canal boats. However, the article notes limitations of lithium-ion batteries for long-haul voyages, prompting consideration of fuel cells utilizing alternative fuels like ammonia or hydrogen for ocean-going vessels. While electric propulsion gains popularity, advanced technologies such as fuel cells are still undergoing development. Corvus Energy's CEO, Fredrik Witte, commends the LR approval for reaffirming the system's safety standards in the maritime sector.
