'Cheaper green hydrogen' | US start-up's novel low-cost electrolyser promises 30% more bang per buck. The founder of Wisconsin-based Advanced Ionics — which emerges from stealth mode today — explains that the Symbiotic electrolyser requires 35kWh of electricity to produce one kilogram of hydrogen

Isn’t hydrogen dangerous because any leak means a massive explosion? So like, transporting it through a pipe is not feasible? There’s some kind of storage issue?

Isn’t hydrogen dangerous because any leak means a massive explosion?

If H2 leaks inside a building it's a big problem, which can be solved with detectors and automatic venting. If it leaks outside, it's so light it rises into the atmosphere, unlike propane which sinks and collects. Here's a hydrogen leak and ignition test

Sometimes accidents happen of course, and so safety is really important. Only trained techs should be involved.

transporting it through a pipe is not feasible?

There are hundreds of miles of hydrogen pipelines in the US, most connecting Gulf Coast refineries. You can read more at https://www.airproducts.com

There’s some kind of storage issue?

Storage of H2 today is compressed or liquid, neither of which is easy but doable and every day engineers are working on it - from China to Germany. Ammonia (NH3) may be a good way. Whatever the issue is an answer will be found.

I appreciate your response. It was informative and well thought out.For some reason, I recall being taught that hydrogen is extremely dangerous, and it’s impossible to keep. It’s looks like I recall wrong.
