Yesterday: Germany Turns to Hydrogen in Quest for Clean Energy Economy https://news.ycombinator.com/item?id=20602407 https://news.ycombinator.com/item?id=20602407 It's 2019 and this is still going on.

  German bit is still part of the great scam. Their green biomass fuel plants are co-firing wood pellets(sourced from chopped forests) together with brown coal in order to whitewash coal power plant into carbon neutral biomass plant.

    This scam nation has today produced between 6-9 GW which is roughly between 12 and 18 percent of the total consumption with wind and water. You are right to pick on brown coal where use has not decreased much but other coal and fossil fuels have.

Still true today. It'll still be true in 2050.

  And yet nobody was hurt. What do you think the outcome had been if a petrol station went up like that?
  - mktmkr 7y ago
    Considering the number of such stations, explosions are rather rare, although one did recently explode in the USA. It turns out to be difficult to get a decent explosion out of bulk liquid petrol. Even setting it on fire is not as easy as some think. Try it with liquid diesel, practically inert. What you really need for a good time is empty petrol tanks.

    If it exploded; the outcome would have been pretty much the same, but i'm probably wrong. I assume the amount of KJ is about the same; hydrogen will blow up much faster and much more violent. Petrol tend to "wooooof" into an fireball and expell a lot of the energy in the fire afterwards. A leak in the petrol tanks at a station won't cause explosions in itself, it causes polluted ground water. Not to mention it's quite hard to get petrol to blow up, you need a pretty specific mix of fuel and air. Hydrogen pretty much blows up no matter what if there is a leak.
