Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
I think anybody who is enthusiastic about the hydrogen economy should go into a lab and try to make even a simple system leakproof. And then try to translate that system into a production version that can be made in volume, maintained at realistic cost, and have a lifetime of a decade or so without failing...

Yes, AFAIU, this is one of the arguments favoring NH3 as a hydrogen energy store: the problem that H2 is such a slippery little bugger.

NH3 fuel cells may be tricky, but its a bottleneck: the difficulty in keeping H2 from leaking is an across the board challenge to fabrication and installation technology across the entire fuel supply chain.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
