Ann: Impairment of Moomba Sydney Ethane Pipeline, page-21

Please show me where it says people can safely transport hydrogen in existing gas transmission pipes? Pipelines will need either some sort of conversion or replacement

but this is only one of many issues if you are relying on the hope that hydrogen will simply replace gas in the pipes.

Other more fundamental issues I mentioned above are that

2. hydrogen producers aren't going to build the hydrogen production plants in the same place that the gas fields are currently. So they are unlikely to need most of APAs existing transmission lines.

3. Hydrogen production costs too much. It is unlikely to be as widely used as gas for this reason.
