Hydrogen combustion produces approximately 142 MJ per kg, but its physical density is very low, at room conditions approximately 81 g/m3. By comparison methane produces 50 MJ/kg with a density of 654 g/m3. Currently, there are existing hydrogen infrastructure projects in progress in Europe (GRHYD in France) to use a mix of methane and hydrogen due to the safety issues and avoiding boiler burner redesign. Hydrogen burns quite differently to methane, with a faster flame speed, and a transparent flame, such that it is harder to control and maintain the flame in steady combustion, and the radiative transfer is weaker than for the visible methane flame. These characteristics require redesign of domestic boiler burners if hydrogen is to be used as a network fuel. A BEIS report by Frazer Nash in April 2018 described how industry has the opportunity to redesign for suitable domestic hydrogen burners. Worgas Ltd are a local company investigating the practical application.

氢气燃烧产生约142 MJ/kg，但其物理密度非常低，在室内条件下约为81 g/m3。相比之下，甲烷产生50 MJ/kg，密度为654 g/m3。目前，由于安全问题和避免锅炉燃烧器重新设计，欧洲正在进行现有的氢基础设施项目（法国的GRHYD），以使用甲烷和氢的混合物。氢气燃烧与甲烷完全不同，具有更快的火焰速度和透明的火焰，使得更难以控制和维持稳定燃烧的火焰，并且辐射传递比可见甲烷火焰弱。这些特点要求重新设计家用锅炉燃烧器，如果氢被用作网络燃料。弗雷泽纳什在2018年4月的一份BEIS报告中描述了工业界如何有机会重新设计合适的家用氢气燃烧器。Worgas Ltd是一家当地公司，正在研究实际应用。
