That’s two ways to unlock energy from hydrogen that’s coming out here .firstly it’s flammable ,so you could just burn it .and secondly ,you could use to power ,what’s called a flue cell .This essentially work like a battery running on hydrogen or oxygen ,they react to supply to electricity that could for example, power of car. The only by-produces are heats and water ,and all of this is not really news , the fuel cell was invented back in 1800s ,later on the same century ,the guy in Denmark ,was called KuMepuwa ,was already use windmills to power electrolysis ,that supplied hydrogen for school gas lamps, and in 1960s , general motors built flue power van ,that run an hydrogen Today ,almost hydrogen we produced is used to make other things ,like fertilizers or petroleum , but it’s never made it big as a fuel .it’s just always be easier and cheaper to directly burn fossil fuels instead, But that is changing .essentially。本质上fertilizers 肥料petroleum 石油 原油electrolysis 电解hydrogen 氢气
