, Paul Martin and I talked about the newly formed Hydrogen Science Coalition, of which Paul is a founding member, embrittlement of steel and increased leakage in transmission. In this second half, we delve into more on hydrogen leakage, especially in homes, the problem of increased risks from hydrogen in buildings, shipping boil-off rate, global supply implications, and more.
We digressed into hydrogen boil-off in shipping. When you have a gas stored as a liquid by keeping it cold at reasonable temperatures, the cryogenic liquid turns into gas with any heat coming in. With ammonia and LNG, you can run compression and cooling equipment and return it, as they are liquids at much higher temperatures than hydrogen with its 24° Kelvin boiling point.
Hydrogen has another pernicious problem, that of spin of the electrons in hydrogen atoms. Basically, they have different spins at different temperatures, and as you cool the hydrogen, it gives off heat due to changes in spin. When the first people made liquid hydrogen at 24° Kelvin, it turned back to gas the next day due to this problem. This means more equipment, energy, and expense.
So there are multiple loss problems along the supply chain, but when we get it into homes, things get even more problematic. We’ve had 100 years of experience making natural gas appliances safe in homes. There are no certified home appliances for hydrogen today, and no jurisdiction has existing building codes that support hydrogen appliances. As I’ve pointed out a few times, building codes and approvals are a, not by country.
Cleantechnica, and hence $tesla, seems to be seriously scared of the hydrogen competition.
Btw, city gas used before 1950 in NY contained sometime more than 50 % of hydrogen. Looks like NY is still intact and well.
Yeah, water rust metals. Battery self ignites, etc, etc? What is the point of publish this with infamous anti-hydrogen lobbyist? Hydrogen embrittlement is known for decades and there are a lot of progresses in dealing with it.
And how are we going to address seasonal fluctuation of renewables, mr Paul Martin?
Hydrogen is still worth investing into.
