Thames Clippers currently provides public transport on the river Thames with catamarans and will expand its services to include freight using a similar catamaran design. As these catamarans operate at high-speed the power installead is large and currently provided via diesel engines. Thames Clippers face increasing regulations and commercial pressure to provide a zero emission solution.Zero emission propulsion systems with sufficient autonomy at high speeds for daily operation on the river infers that a substantial quantity of a low energy density fuel by volume is required. Fitting this fuel volume inside the catamaran together with other operational demands, such as passenger seat capacity or freight volumes, is a complex problem. Although fuel cell electric drive systems for marine propulsion are now becoming mature technology, the fuel choice remains an open question. Consequently, Thames Clippers proposes a feasibility study to integrate such a propulsion system into their catamaran platform for new catamarans and retrofitting into some of their existing fleet.The key objective is to gain a better understanding of economic and technical driving factors of three zero carbon fuel candidates within the design constraints of the current catamaran platform, i.e., speed, passenger and freight capacities, limited main dimensions, air-draught, etc. The likely fuel choices are compressed hydrogen gas, liquid hydrogen and methanol. The result of the study will allow Thames Clippers to make an informed future choice for their ideal propulsion package for their fleet extension and retrofit options for passenger and freight services with the most commercially beneficial fuel.Thames Clippers is supported by Mayfair Marine as a hydrogen marine consultant, Class Society DNV for regulatory support and catamaran designers One2three Naval Architects. A feasibility study is planned to investigate economic, technical, regulatory and operational aspects of the catamaran platform whilst considering the fuel choices. Efficiency opportunities for each fuel choice will be evaluated, for instance using the cryogenic latent heat of liquid hydrogen to power the air-conditioning system, amongst others.Each fuel path (i.e., emissions and costs from source to propelled wake) will be evaluated to determine the commercial impact. An information exchange with another CMDC application, project HOST where Thames Clippers is also a partner, will improve the accuracy of establishing the fuel path costs within the Thames Gateway. Expecting that alternative fuels are more expensive compared to conventional fuels, the economic understanding, i.e., commercial impact, is equally important as the technical feasibility.

泰晤士快船目前在泰晤士河上提供双体船公共交通，并将扩大其服务，包括使用类似的双体船设计的货运。由于这些双体船在高速下运行，因此动力装置很大，目前通过柴油发动机提供。Thames Clippers面临着越来越多的法规和商业压力，要求其提供零排放解决方案。具有足够自主性的零排放推进系统在高速下进行日常河上运行，这意味着需要大量的低能量密度燃料。将该燃料体积与其他操作需求（例如乘客座位容量或货物体积）一起装配在双体船内是一个复杂的问题。虽然燃料电池电力驱动系统的船舶推进现在已经成为成熟的技术，燃料的选择仍然是一个悬而未决的问题。因此，Thames Clippers提出了一项可行性研究，将这种推进系统集成到他们的双体船平台上，用于新的双体船，并改装到他们现有的一些船队中。其主要目标是在当前双体船平台的设计限制范围内，更好地了解三种零碳燃料候选物的经济和技术驱动因素，即，速度、载客量和货运量、有限的主要尺寸、通风量等。可能的燃料选择是压缩氢气、液态氢和甲醇。该研究的结果将使泰晤士快船为他们的船队扩展和改造方案的客运和货运服务提供最具商业效益的燃料的理想推进包做出明智的未来选择。泰晤士快船得到了梅菲尔海事公司作为氢海洋顾问，船级社DNV的监管支持和双体船设计师One2three海军建筑师的支持。计划进行可行性研究，调查双体船平台的经济、技术、监管和运营方面，同时考虑燃料选择。将评估每种燃料选择的效率机会，例如使用液氢的低温潜热为空调系统提供动力等。排放量和从源到推进尾流的成本）将被评估以确定商业影响。与另一个CMDC应用程序（项目HOST，其中泰晤士快船也是合作伙伴）的信息交换将提高在泰晤士门户内建立燃料路径成本的准确性。预计替代燃料比传统燃料更昂贵，经济上的理解，即，商业影响与技术可行性同样重要。
