Demonstration of Ultra-Long-Endurance Hydrogen-Powered Uncrewed Surface Vessels

ACUA Ocean （AO）是一家清洁海事初创公司，该公司设计了一种长航时液氢动力无人水面船（H-USV）（正在申请专利）。通过结合海事领域发展最快的两种技术：氢和自主氢动力无人水面舰艇（H-USV），可以在5节和8400海里的航程下提供长达70天的海上续航力。目前市场上可用的大多数usv由于续航能力低或有效载荷能力有限，商业可行性有限。风浪驱动的usv续航时间长，但有效载荷能力有限；电动usv的续航力和有效载荷能力有限，需要频繁充电，限制了其操作范围，尽管柴油动力usv具有较高的有效载荷能力和潜在航程，但其续航力受到发电机维护要求的限制，不符合清洁海事计划的零排放目标。AO的H-USV创新设计克服了这些限制和挑战，将大量液态氢整合到更小的USV中，以支持到2050年向净零过渡的技术发展。该项目将证明，在USV平台中集成氢系统不仅会产生更可持续的解决方案，减少温室气体排放，而且与传统的柴油动力船舶相比，更具成本效益停机时间和维护要求。监管环境的发展和h - usv的技术设计将支持到2050年向净零过渡的技术发展。基础原型以及在此演示过程中建立的监管，操作和技术交付成果以及专有技术将加速在海运业中采用多种类型的液氢动力船舶。

ACUA Ocean (AO) is a clean-maritime start-up that has designed (patent pending) a long-endurance liquid hydrogen-powered uncrewed surface vessel (H-USV). By combining two of the fastest growing technologies in the maritime sector: hydrogen and autonomy hydrogen-powered uncrewed surface vessels (H-USV) can deliver increased offshore endurance of up to 70 days at 5 Knots and a range of 8400 Nm.Most USVs available on the market today have limited commercial viability due to low endurance or restricted payload capacities. Wind/wave powered USVs have a long endurance but have limited payload capacity; electric powered USVs have limited endurance and payload capacity requiring frequent recharging limiting their operational range, and although diesel-powered USVs have high payload capacity and potential range, their endurance is limited by the maintenance requirements of the generators and do not meet the zero emission target of the Clean Maritime Plan.AO's H-USV innovative design overcomes these limitations and the challenges of incorporating large volumes of liquid hydrogen into smaller USVs that support the development of technologies supporting the transition to Net Zero by 2050This project will demonstrate that integrating a hydrogen system in a USV platform will not only result in a more sustainable solution with lower GHG emissions but also one that is more cost-effective compared to traditional diesel-powered vessels whilst reducing downtime and maintenance requirements.Development of the regulatory environment and technical design of H-USVs will support the development of technologies supporting the transition to Net Zero by 2050\. The foundational prototype along with the regulatory, operational and technical deliverables and know-how established during this demonstration will enable the accelerated adoption of multiple types of liquid hydrogen powered vessels across the maritime industry.
