800 bar is 11,500 PSI. No thanks, I don't want that anywhere near me in an accident. You also can't change the fact hydrogen needs to be at -253C to remain liquid.

Compressed gas is not liquid, it is room temperature.

Yes it is and it has low density compared to a liquid and therefore a lower energy content.

By volume you are correct. By weight, the energy content of the hydrogen is 100% identical. At 800 bar, you have about the density of compressed hydrogen at room temperature (approx. 36 kg/m3) vs. liquid hydrogen at -252C. The weight of the composite cylinder would be considerably less than the weight of a cryogenic tank.

I had an old truck that was dual fuel, gas and propane. I wasn't entirely comfortable having a tank behind men pressurized to only 10 bar.

I prefer charcoal (real, not those chemical briquettes) as well.

Me too, especially if you're grilling a steak. Although you then have all those cow farts that led up to your dinner main course.

I have been keeping close comms. with an old friend of mine who now lives in Nfld. especially as she goes through this wicked storm that hit the island. She lives in a house in an area on the harbor known as "The Battery". Her neighbors house was one flattened by an avalanche that it looks like occurred as a result of combination of heavy snow fall and hurricane level winds. The mayor declared a state of emergency and ordered that area evacuated so she ended up having to walk a km or so to get to where she could get a ride in a police car to a downtown hotel. I was going to complain about having to shovel a foot or so off my driveway here on the west coast, but I think now I'll shut up.

Clearly climate change is a hoax - it's cold outside here where I live.

Of course. Trump sent this snow to remind us that he knows better, and maybe to convince us to buy more coal.

Clearly I was wrong - it was borderline melting today.

My friend on "the other island" tells me things have gone beyond "an elf on the shelf" to, "a moose on the roof"
Only in Newfoundland.

Luckily the Nfld. Constabulary gave him an escort out of town.

Climate Change denial isn't all bad... it may have destroyed Libertarianism.

Tell me again where libertarian policies have been implemented to fight climate change?

Sorry, I don't think that the article says that.
