This is close to becoming a FUD argument. Hydrogen does not leak out of properly designed pipes and containers in appreciable quantities. Embrittlement doesn't not happen either except for specific cases or where an incorrect alloy was used. These are mostly solved problems in modern times.
- TheAdamAndChe 6y agoIf you have hundreds or thousands of miles of pipes installed by third-party contractors, the existence of improperly designed pipes, incorrect alloys, and corner cutting becomes virtually inevitable.
- jonstewart 6y agoI don’t know about such things, so have a well-intentioned question: are these problems solvable at scale at reasonable cost? One hears about pipeline leaks frequently, and hundred+ mile long pipelines seem like a hard thing to construct with rigorous precision.
- Hypx 6y agohttps://en.wikipedia.org/wiki/Hydrogen_pipeline_transport https://en.wikipedia.org/wiki/Hydrogen_pipeline_transport Hydrogen pipelines exist and for the most part work as intended. There are straightforward ways of avoiding the main problems. AFAIK, these are cost effective solutions.

- gambiting 6y agoLast time I was at university we stored hydrogen in pure lead bottles(70kg bottle for just 1L of hydrogen!) and it would leak all of it naturally over about 4-6 weeks. And the bottles had to be replaced every now and then because hydrogen makes them brittle while permeating through them. Has that changed? Do we now have some exotic materials that can hold it better than pure lead?

- hinkley 6y agoThe NASA planned replacement for the space shuttle had a bunch of setbacks, but what killed it was the carbon fiber cryo tanks delaminating. They couldn’t solve the problem fast enough and it all got shitcanned. Has that been solved now? The Mirai can have a low pressure tank, fed from a much larger, higher pressure tank at the fuel station. That tank and the delivery systems for it are separate problems that also have to be solved at scale. “At scale” is the problem that public policy has to wrestle with. Just because you can do something doesn’t mean you can do it for everybody.
- Hypx 6y agoThat was in the 1990s. Not to mention they were trying to build a non-cylindrical tank which made things significantly harder.
