Some chemical factories make hydrogen gas (H2) using a process called steam methane reforming. In this process, methane (CH4) combines with steam (H2O) at high temperatures to form a mixture of hydrogen gas and carbon monoxide (CO). This mixture can then be used to make substances like hydrogen fuel and ammonia
