Prototype of a power train for hydrogen vessels

Acua Ocean通过CMDC1 Strand 2成功开发和测试了非商用低压概念动力总成系统。自CDMC1以来，已有多家公司与Acua和三叉戟船舶电气公司接洽，以采购氢动力总成系统。AO还发现了全球氢电供应链的挑战，供应商数量有限(Torqeedo和EODev)。替代零排放解决方案(如Torqeedo和Evoy)专注于通用电池技术，由于锂离子电池的低功率密度，其续航能力非常有限，不适合许多商业和休闲海洋活动。与英国领先的电力推进产品/系统创新者Krensen和英国最令人兴奋的海洋电气工程初创公司之一TME合作，该联盟申请提供一种创新的海上液氢动力总成解决方案，可用于娱乐和商业船只上的多艘船只。拟议的氢动力总成系统将：*将电池系统从24V增加到360V系统，*将发动机功率从10kw提高到200kw*优化动力总成效率-专注于充电和从DC到AC的移除步骤*改进燃料电池系统*开发智能控制系统和用户界面此次研发应用程序合作将向TRL5提供可供第三方商业使用的动力总成系统的非商业性工厂验收测试演示，支持CMDC 2的优先技术重点，用于新的和新颖的设计和零排放推进系统。商业开发旨在将用途扩大到AO船以外，包括娱乐和商业、中小型和无人值守船舶--包括新的安装和改装。这些市场包括全球3000万艘游艇行业，2022年价值290亿美元。此外，该动力总成系统可以部署在包括数十亿美元的拖网捕鱼市场和快速增长的近海巡逻船市场在内的商船上。这个为期8个月的工业合作研发项目独特地解决了CMDC2的多个优先创新挑战：1.通过优化动力总成设计和船舶推进进行全船能效设计和集成2.安全的船上储存氢气和氨气3。辅助发动机，例如电池、燃料电池，使用氢、甲醇或氨等低碳或零碳替代燃料8个月产业研发合作的符合条件的总成本为GB 564,653(70%赠款，30%现有储备匹配资金)；*AO：GB 310,516\&gt；GB 217,361(70%)/GB 93,155(30%)*克伦森：GB 159,800\&gt；GB 47,940(70%)/GB 54,772(30%)*TME：GB 94,337\&gt；GB 66,036(70%)/GB 28,301(30%)

ACUA Ocean through CMDC1 Strand 2, successfully developed and tested a non-commercial low voltage concept powertrain system. Since CDMC1 multiple companies have approached ACUA and Trident Marine Electrical to procure a hydrogen-powertrain system.AO also identified challenges in the global hydrogen-electric supply chain, with a limited number of suppliers (Torqeedo and EODev). Alternative zero-emission solutions (such as Torqeedo and Evoy) focus on generic battery technology which due to the low-power density of lithium ion batteries have very limited endurance/ range and are not suitable for many commercial and recreational marine activities.In partnership with Krensen, a leading British innovator in electric propulsion-based products/systems and TME, one of the UK's most exciting marine electrical engineering startups - this consortium application looks to deliver an innovative marinised liquid hydrogen-powertrain solution that can be used in multiple vessels across recreational and commercial vessels.The proposed hydrogen-power train system will:* increase battery to 360v system from 24v,* increase engine power from 10kw to 200kw* optimise the powertrain efficiency - focus on chargingcharing and removal of DC to AC steps* marinise the fuel cell system* develop a smart control system and user interfaceThis R&D application collaboration will deliver a non-commercial Factory Acceptance Test demonstration to TRL5 of the power-train system that is commercially available to third parties, supporting the priority technology focus of CMDC 2 for new and novel design and zero-emission propulsion systems. Commercial exploitation aims to expand use beyond the AO vessel to include recreational and commercial small and medium sized crewed and uncrewed vessels - including new installations and retrofits. These markets include the 30m global recreational boat sector, valued at $29bn in 2022\. Additionally, this powertrain system could be deployed in commercial vessels including the multi-billion dollar fishing trawling market and the fast growing Offshore Patrol Vessels market.This 8-month industrial collaborative R&D project uniquely addresses multiple CMDC2 priority innovation challenges of;1. Whole-ship energy efficiency design and integration through optimisation of the powertrain design and vessel propulsion2. Safe on-board storage of hydrogen and ammonia3. Auxiliary engines, for example, battery, fuel cell, using low or zero carbon alternative fuels such as hydrogen, methanol or ammoniaTotal eligible costs for 8-month industrial R&D collaboration are £564,653 (70% grant, 30% match-funding from existing reserves);* AO: £310,516 \> £217,361 (70%) / £93,155 (30%)* Krensen: £159,800 \> £47,940 (70%) / £54,772 (30%)* TME: £94,337 \> £66,036 (70%) / £28,301 (30%)
