The reason we don't have a lot of hydrogen right know is because we don't have a lot of surplus energy right now. It makes no sense to buy expensive equipment and run in only a few hundred hours a year.
- pfdietz 3y agoWe have huge amounts of hydrogen right now. At standard temperature and pressure, the amount of hydrogen made globally each year would occupy 700 cubic kilometers of volume. It's just that it's made overwhelmingly from fossil fuels, mostly natural gas (6% of global gas production goes to making hydrogen). That this is being done instead of making green hydrogen is because CO2 from the fossil fuel process is not being taxed or otherwise forced to account for the negative externalities. This also illustrates that producing hydrogen without CO2 release is not an optionally solvable problem. Without the ammonia made from hydrogen (which is where most of it is going) billions will starve.
