I have an acquaintance who has made a substantial fortune from energy focused startups (including a battery tech one) and is now working on another hard tech startup and they are very critical of hydrogen as a fuel. I’ve had superficial conversations with them about it but could never get a sense of their fundamental arguments. Is hydrogen a non starter or are they just protecting their investments with FUD?

Here a few major issues hydrogen would need to solve. * There isn't a fuel distribution system. The reason BEVs work is because everywhere has power, setting up power distribution is generally just plugging into the local grid. * Hydrogen escapes any container it's placed in. That's a pretty hard thing to deal with. Most approaches have looked at chemically binding hydrogen to something in order to keep it from escap…

Since “tank” isn’t a unit of measure, I suppose anyone could trivially break the record with a larger tank. From the article: > The Nexo consumed 6.27kg of H2 For comparison with the other production H2 cars: Toyota Mirai: 5.6kg Honda Clarity: 5.0kg Seems like a promising technology. My understanding is that the current blocker is infrastructure. It’s hard to pressurize up to 10,000 PSI, so many facilities are only a…

10,000PSI hydraulics are rapidly becoming cookie cutter commodity parts. Once you have the supply chain for all the little crap that nickles and dimes you the rest is a lot cheaper. Having industry expertise at working at those pressures really has a huge multiplier effect on everything else. Building a system to plumb stuff from A to B at a pressure nobody uses is expensive. Calling up a sales rep and asking for sli…

> “I was constantly checking the Nexo’s efficiency readout to maximise the distance I was getting per kilogram of hydrogen. I found that by using techniques from rally driving, such as looking as far down the road as possible, as well as tips I have learned from my dad for driving a truck efficiently over long distances, it’s actually possible to go way beyond Nexo’s official range.” Anyone have some insights on this…
