![]() ![]() ![]() Electrolysis itself does not produce any byproducts or emissions other than hydrogen and oxygen. On a large, commercial scale, the process may be referred to as power-to-gas, where power is electricity and hydrogen is gas. ![]() Electrolysis is commonly used in high school science classes to demonstrate chemical reactions and hydrogen production. Electrolysis uses electricity to produce hydrogenĮlectrolysis is a process that splits hydrogen from water using an electric current. Biofuels and petroleum fuels are also potential hydrogen sources. Several fuel cell power plants in the United States treat and use landfill gas (biogas) as hydrogen source. Industrial facilities and petroleum refineries primarily use natural gas as the methane source for hydrogen production. In steam-methane reforming, high-temperature steam (1,300☏ to 1,800☏) under 3 bar–25 bar pressure (1 bar = 14.5 pounds per square inch) reacts with methane in the presence of a catalyst to produce hydrogen, carbon monoxide, and a relatively small amount of carbon dioxide (CO 2). Commercial hydrogen producers and petroleum refineries use steam-methane reforming to separate hydrogen atoms from carbon atoms in methane (CH 4). Steam-methane reforming accounts for nearly all commercially produced hydrogen in the United States.

Yes, but saying that it should is another very different question.
