- it has an abysmal energy density per unit volume, even as a liquid. E.g. if you used to need 1 tanker or gasoline, you’ll need 18 tankers of compressed hydrogen for the same energy content.
- compressing and liquifying it is much more expensive and challanging that natural gas. See this fun little challange [0]
- there are currently no odorants available for use in hydrogen (the thing that gives natural gas it’s smell). All the available ones either react with hydrogen or poison your fuel cell
- it’s flame is essentially invisible and incredibly hot
- it has an explosive range from 4-75% (natural gas for example is 5-17%)
