Webb4 apr. 2024 · Where this falls down, however, is that hydrogen engines emit nitrogen oxide particulates (NOx) over a certain temperature. In some applications, such as JCB’s hydrogen combustion diggers, the solution is to simply run the engines at a lower temperature than would create the problem. However, that obviously won’t work with a … Webb15 juli 2024 · Hydrogen fuel can be produced through several methods. The most commonly used methods today are natural gas reforming (a thermal process), and electrolysis of water, which sees electricity running through water to separate the hydrogen and oxygen atoms. The electricity used can be generated by wind, solar and hydro sources.
