The small-craft (Sub-IMO) industry has traditionally used "marinized" engines for propulsion for a wide variety of craft, including leisure, commercial and fishing vessels. A large proportion of these are diesel engines which are based on automotive engines that are no longer in development as manufacturers move to electric or hydrogen propulsion.This is creating supply issues for diesel engines in the short term, which will only get worse in the medium term. It is also driving manufacturers to install larger, heaver and proportionally more polluting engines into their vessels. This is creating a driver for the small-craft industry to move away from diesel to cleaner fuels, bit this is not supported by the level of R&D that it previously enjoyed.Whilst pure electrical power may provide a viable solution to the automotive market, the mass of batteries and overall power requirements for the small craft market mean that pure electrical propulsion is less feasible for small, faster sea-going craft. Other alternative fuels do not have a sufficient energy-density to be stored on small craft, where weight and internal storage volume are critical. This is creating a significant problem for small-craft manufacturers, who currently have little other choice in fuel or propulsion technology -- especially if they want to move to clean technology.In the longer term (with a suitable supply infrastructure) ammonia will provide a more feasible energy source for internal combustion engines as a dedicated power source linked to the propulsor or to power a generator in a hybrid system to charge batteries and extend range.This project will create a novel, compact, lightweight but powerful internal combustion engine which is optimised to run on ammonia. The engine will feature novel technology to address come of the known issues with ammonia fuel. The size, weight and power output will be suitable for small craft.In addition, work will be undertaken to assess the impact of the engine on potential performance for an example end-user, including range and speed to quantify any operational impact.These results will be used to inform a complete Life-Cycle Assessment to determine the overall impact of the installation and use of both fuels in a representative small-craft. All the information and data gathered will then be used to create an assessment of the technical and economic feasibility of ammonia engines in small craft, informing the route to commercialisation.

小型船舶（Sub-IMO）行业传统上使用“船用”发动机为各种船舶提供推进力，包括休闲船、商业船和渔船。其中很大一部分是基于汽车发动机的柴油发动机，随着制造商转向电动或氢推进，这些发动机已不再开发。这在短期内造成了柴油发动机的供应问题，并且在中期只会变得更糟学期。它还促使制造商在其船舶上安装更大、更重且污染程度更高的发动机。这正在推动小型船舶工业从柴油转向更清洁的燃料，但这并没有得到以前享有的研发水平的支持。虽然纯电力可能为汽车市场提供可行的解决方案，但小型船舶市场的电池质量和总体电力要求意味着纯电力推进对于小型、更快的海上船舶来说不太可行。其他替代燃料没有足够的能量密度来存储在小型船只上，因为小型船只的重量和内部存储体积至关重要。这给小型船舶制造商带来了一个重大问题，他们目前在燃料或推进技术方面几乎没有其他选择，特别是如果他们想转向清洁技术。从长远来看（拥有合适的供应基础设施）氨将提供为内燃机提供更可行的能源，作为与推进器相连的专用电源，或为混合动力系统中的发电机提供动力，为电池充电并扩大行驶里程。该项目将创造一种新颖、紧凑、轻便但功能强大的内燃机，优化以氨运行。该发动机将采用新技术来解决氨燃料的已知问题。尺寸、重量和功率输出将适合小型船只。此外，还将开展工作以评估发动机对最终用户示例潜在性能的影响，包括范围和速度，以量化任何操作影响。这些结果将用于为完整的生命周期评估提供信息，以确定在代表性小型船舶中安装和使用两种燃料的总体影响。收集到的所有信息和数据将用于对小型船舶中氨发动机的技术和经济可行性进行评估，为商业化路线提供信息。
