Domestic heating accounts for approximately 14% of the UK's CO2 emissions, with about 85% of homes using gas-fired boilers to provide heating. There is a real need to reduce household CO2 emissions to meet the Government's Net Zero Targets by 2050, as set out under the Climate Change Act.The use of hydrogen gas in domestic boilers to heat homes is one of the routes to decarbonisation, detailed in the UK Hydrogen Strategy. This could involve the use of either 100% hydrogen gas or a blend of natural gas and hydrogen.The use of hydrogen could cause a number of issues with domestic boiler systems:-Hydrogen gas burns with a higher adiabatic flame temperature than natural gas, which means that boiler components will need to be engineered for more extreme conditions.-The higher flame temperature is likely to increase the amount of nitrous oxide (NOx) generation, which could be as high as about 39%, with an "averaged" increase of 8%.The presence of NOx could lead to health issues, especially in densely populated areas, where there is a high concentration of boilers. We need a method of adapting existing central heating systems to make them compatible with hydrogen as a fuel source.We have developed a unique heating system, based on catalytic combustion technology, capable of being retrofitted to existing gas boilers. A key advantage is its compatibility with existing domestic heating infrastructure, such as pipework and radiators.In this project, we will build a demonstrator unit to prove our concept, operating it under "real world" conditions to understand and measure performance. We will then use this information to scale up the design and manufacture of these units, as an enabler to widespread adoption of our novel technology.

家庭供暖约占英国二氧化碳排放量的 14%，约 85% 的家庭使用燃气锅炉供暖。确实需要减少家庭二氧化碳排放，以实现《气候变化法案》规定的到 2050 年政府的净零排放目标。在家用锅炉中使用氢气为家庭供暖是脱碳的途径之一，英国氢战略对此进行了详细说明。这可能涉及使用 100% 氢气或天然气和氢气的混合物。使用氢气可能会给家用锅炉系统带来许多问题： - 氢气燃烧时的绝热火焰温度高于天然气，这意味着锅炉组件需要针对更极端的条件进行设计。 - 较高的火焰温度可能会增加一氧化二氮 (NOx) 的生成量，其生成量可能高达 39% 左右，并且 “平均”增加 8%。氮氧化物的存在可能会导致健康问题，特别是在人口稠密的地区，那里的锅炉高度集中。我们需要一种改造现有中央供暖系统的方法，使其与氢气作为燃料来源兼容。我们开发了一种基于催化燃烧技术的独特供暖系统，能够对现有燃气锅炉进行改造。一个关键优势是它与现有的国内供热基础设施（例如管道和散热器）兼容。在这个项目中，我们将建造一个演示装置来证明我们的概念，在“现实世界”条件下运行它以了解和测量性能。然后，我们将利用这些信息来扩大这些装置的设计和制造规模，从而推动我们的新技术得到广泛采用。
