Domestic Catalytic boiler module bridging the gap to a hydrogen network

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。根据《气候变化法案》的规定，到2050年，减少家庭二氧化碳排放以实现政府的净零排放目标是非常必要的。《英国氢战略》详细介绍了在家用锅炉中使用氢气为家庭供暖是脱碳的途径之一。这可能涉及使用100%氢气或天然气和氢气的混合物。氢气的使用可能会给家用锅炉系统带来一系列问题：-氢气燃烧时的绝热火焰温度比天然气高，这意味着锅炉部件需要设计成更极端的条件。-较高的火焰温度可能会增加一氧化二氮（NOx）的生成量，可能高达39%左右，“平均”增加8%。氮氧化物的存在可能导致健康问题，特别是在锅炉高度集中的人口稠密地区。我们需要一种方法来调整现有的中央供暖系统，使其与氢作为燃料来源兼容。我们开发了一种独特的加热系统，基于催化燃烧技术，能够改造现有的燃气锅炉。一个关键的优势是它与现有的家庭供暖基础设施，如管道和散热器的兼容性。在这个项目中，我们将建立一个演示单元来证明我们的概念，在“真实世界”的条件下操作它，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，作为广泛采用我们的新技术的推动者。

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.
