HEAT-HD is a game-changing high-temperature liquid-ammonia (LNH3) powered engine technology with 70% BTE. Targeting marine propulsion systems and Auxiliary Power Units (APUs) and shore-side power generation units up to 10MW.LNH3 has clear economic and operational benefits for maritime applications as it offers the energy storage density and true zero emission property of liquid hydrogen without the parasitic losses associated with storing cryogenic liquids. Ammonia technology is specifically targeting the heavy-duty marine sector. HPDI injector technology will enable a new generation of high-efficiency LNH3 engines that offer lower emissions than comparable port-fuelled engines.HEAT-HD will develop a novel LNH3 fuel system and engine concept combining four unique technologies together to tackle critical challenges of using LNH3 as a fuel, a clear step-change from current SOTA NH3 ICE technologies for marine applications. The four unique technologies included and their advantages are:1. High-temperature (thermally insulated) Carnot engine with key components manufactured from high temperature resistant materials able to withstand fuel combustion temperatures, eliminating the third of fuel-energy wasted to cooling systems2. HPDI fuel injection strategy for improved performance and reduce in-cylinder emission and knock3. Active pre-chamber TJI concept with multi-point ignition for ultra-lean combustion and cold-start operation.4. Cracking of ammonia in-situ to provide the hydrogen pilot for the ammonia engine to achieve efficient combustion.The pre-chamber Turbulent Jet Ignition (TJI) concept will optimise secondary combustion, with small hydrogen consumption, cracked from ammonia in-situ.The project is a feasibility and lab-based demonstration study to assess the technical, economic and regulatory feasibility of using Carnot's technology to reduce GHG emissions using LNH3 as the primary fuel source. The project will develop and demonstrate a dual-fuel hydrogen-piloted fuel system with only ammonia stored, a proportion cracked to hydrogen, via the Transformational Energy (TE) SOFC Ammonia cracking technology, and will identify the design elements required to convert to this fuel-system. It will employ comprehensive physics-based modelling expertise from University of Southampton to simulate LNH3 engine combustion covering the four unique technologies, complemented by Brunel University's optical chambers to validate combustion dynamics, before targeting a Carnot engine test at the end of the project. Carnot will also engage with Carisbrooke and OS Energy (OSE) as end users to explore technology commercialisation via duty cycle data collection on board vessels, data analysis and exploration of potential system integration opportunities.HEAT-HD aims to break down one of the main barriers to ammonia being adopted as a marine fuel.

HEAT-HD 是一种改变游戏规则的高温液氨 (LNH3) 动力发动机技术，BTE 为 70%。针对船舶推进系统和辅助动力装置 (APU) 以及高达 10MW 的岸边发电装置。LNH3 对于海上应用具有明显的经济和运营优势，因为它提供液氢的能量存储密度和真正的零排放特性，且无寄生特性与储存低温液体相关的损失。氨技术专门针对重型海洋领域。 HPDI 喷射器技术将使新一代高效 LNH3 发动机成为可能，与同类端口燃料发动机相比，排放量更低。HEAT-HD 将开发一种新颖的 LNH3 燃油系统和发动机概念，将四种独特的技术结合在一起，以应对使用 LNH3 的关键挑战作为燃料，与当前用于海洋应用的 SOTA NH3 ICE 技术相比，这是一个明显的进步。其中包括的四项独特技术及其优点是： 1．高温（隔热）卡诺发动机的关键部件由耐高温材料制成，能够承受燃料燃烧温度，消除了浪费在冷却系统中的燃料能源的三分之一2。 HPDI 燃油喷射策略可提高性能并减少缸内排放和爆震3。主动预燃室 TJI 概念，具有多点点火，可实现超稀薄燃烧和冷启动操作。4。氨原位裂解，为氨发动机提供氢气先导，实现高效燃烧。预燃室湍流喷射点火（TJI）概念将优化氨原位裂解的二次燃烧，氢气消耗量小。该项目是一项基于实验室的可行性示范研究，旨在评估使用卡诺技术以 LNH3 作为主要燃料来源减少温室气体排放的技术、经济和监管可行性。该项目将开发和演示一种双燃料氢引导燃料系统，仅存储氨，通过转型能源 (TE) SOFC 氨裂解技术将一部分裂解为氢气，并将确定转换为这种燃料所需的设计元素-系统。它将利用南安普顿大学基于物理的综合建模专业知识来模拟 LNH3 发动机燃烧，涵盖四种独特的技术，并辅以布鲁内尔大学的光学室来验证燃烧动力学，然后在项目结束时进行卡诺发动机测试。 Carnot 还将与作为最终用户的 Carisbrooke 和 OS Energy (OSE) 合作，通过船上工作周期数据收集、数据分析和探索潜在的系统集成机会来探索技术商业化。HEAT-HD 旨在打破主要障碍之一氨被用作船用燃料。
