There do exist materials for which hyrdogen embrittlement is 'solved,' but they are far too expensive to build 2M miles of pipe. Transportation at scale is a difficult challenge, and an active goal of a lot of metallurgy research.
- pfdietz 5y agoYou don't need 2M miles of hydrogen pipeline to use hydrogen as a grid backup. It's not clear you need much if any for that purpose: make and use the hydrogen at the storage site. Most of that 2M miles of natural gas pipeline will be for distribution. To be clear: I'm not talking about replacing consumer natural gas with hydrogen.
