    Not sure - there was talk about it happening - but I thought that was in the "we might do this plan". But - who knows, the media only tell us what they want us to know.

    I just did a quick check on the most popular engines at the time - which was local to Australia. There are some vast differences between countries - we've had much bigger engines in some small cars than say, UK. And to really mess the figures, there was a time when Diesel was far more popular in small cars than today.

    Giving some accuracy to the numbers, comparing apples-to-apples, I filtered to gasoline 120hp.
    Other approaches may be pursued, of course, but there is no way traditional ICEs come closer to HV in the sense of overall/real world Fuel consumption.

    Yes, I can see that - I just looked up the years and the numbers, picking the most common version selected as being representative.

    If I'd picked BMW 3 series, in 2000, the 318i was by far the most commonly bought, 320i in 2010, 330i in 2019.

    What I said was that they have been improving appreciably - albeit from a poor starting point. My point was that manufacturers have been still working to improve both their Diesel and Petrol cars, with appreciable results. Also bearing in mind that they're also heavier and more powerful. Engines are bigger often - or smaller with turbos to make more and more power - but with better economy.

    I guess it is still in trials, but I understand Japan is desperate.

    I thought they were going to use ships.

    Not sure - as long as it's not air-ships.

    I'm not sure - is it compressed, or liquid? I've never thought about it.

    The articles I found said liquid.I expect compressed too.

    Liquid is more efficient in kilograms of hydrogen per volume, and the tanks are much, much cheaper at tanker ship size.

    lol. The term greenwashing is over used, but here it is appropriate. Likely water pollution for australia but not significant air pollution (other than carbon dioxide (probably lower than cars substituted).

    Hydrogen is a poor fit for the US, but a better fit for Japan (more concentrated population, poor electrical infrastructure, expensive electricity, lower vmt). It is even worse for australia than the US.

    Australia likely would benefit from phevs and bevs. Hopefully then next gen prius is a purpose built phev (an improved prime). They could probably do well with a 12 kwh liquid cooled pack in a awd aerodynamic tall hatch (aka as small CUV).

    While technically you can compress liquids at very high pressures, in practice you can't and pretty much all basic thermodynamics approximate liquids (and solids) as non-compressible.

    You might be thinking that in order to liquefy a gas you compress the gas first.

    I took compressed to mean the high pressure gas like is used in hydrogen cars.
    You can ship more hydrogen while it is liquid. Some will be lost to venting. The vent rate of liquid hydrogen in cars generally works out to an empty tank in a week or two, but a ship has the space for extra insulation, the mass of hydrogen won't heat up as quickly, and there could even have chillers for the tank(s).

    But can you transport that coal ash safely and economically away from where the power is generated close to the rich folks and out to some county (like mine) which is politically weak because the politicians are bought with corporate donations? About 10 miles across town is where they are dumping it. Meanwhile a rock quarry just got approved for land directly across from a 3000 residence single family development. We spent $775k fighting it to the state supreme court and the idea was rejected by the local board but they were then told by the courts to reverse their decision. Citizens United outflows both.
