It is no secret that hydrogen energy is at the top of the clean energy list. It is also a fact that the use of hydrogen energy has become a worldwide trend. From a manufacturing point of view, hydrogen is H2, so if we electrolyse water (H2O) and separate the oxygen (O), we can produce much hydrogen. In electrolysis, in terms of the physical factor, it consumes ten times much hydrogen to produce one unit of electricity. In other words, the composition is 10: 1, which goes far beyond the framework of economic structure.

 However, technology is advancing much more quickly, so if we can expect to compress the ratio to around 5:1, which will bring us closer to profitability. To use a modern analogy with the price of petrol, where a litre of gas costs 150 yen, then a litre of hydrogen would cost 750 yen a litre (for example), and will the government cover a large part of it? Hydrogen itself does not emit CO2. Still, hydrogen production does emit a large amount of CO2, so it is essential to clarify the amount of CO2 emitted during the production process.
