Electric Vs Hydrogen
I read an interesting article that stated that electric vehicles will never be accepted as a genuine replacement for the ICE and will only be around for about 10 years.
From 2030 (or sooner) Hydrogen celled cars will be the next generation with cheaper and greener build costs and a lot more mileage. If I am still alive I doubt if I will still be driving so I wont be bothered anyway |

Hydrogen has a wonderful exhaust product.... water...
The real issue is the hydrogen station.. its not currently economic to put fill stations everywhere as they are like a mini nuclear reactor in complexity, and therefore cost and compliance. That said... in Queensland... there is a University trial of 15 Hydrogen powered vehicles, all filled from one of these new whizz bang BOC hydrogen fill stations located on the campus. Here's hoping it is successful |

Yes, the main issue in the U.K. is that there are apparently only 6 fuel stations in the whole country able to refuel your FCEV! If you think service stations finding a location on their forecourts for EV chargers is difficult for them, it’s easy compared with storing hydrogen....
And let’s be clear, the hydrogen fuel cell is producing electricity to power the car, so it’s still an EV. The two on the market in the U.K. (Toyota and Hyundai) still have a battery pack, but obviously this can be smaller than a BEV pack. But then the high pressure hydrogen storage tanks and fuel cell have to be incorporated...... It’s great technology, and am sure will become more refined, cheaper and popular. But you won’t have the convenience of topping up at home overnight, if you are able to do so with your BEV, and the supply infrastructure will be more of a headache than the electric chargers are now! But, like Gordon, it is unlikely to be of concern to me.... |

When we talk hydrogen powered it's important to distinguish between hydrogen fuel cell vehicles where the fuel cell basically replaces the lithium battery in an electric vehicle and vehicles that burn hydrogen in an internal combustion engine.
The latter still produces harmful NOx emissions as part of the combustion process unless the power output of the engine is reduced to a level far below that of a comparable fossil fueled car (roughly half). The biggest issue with hydrogen is the amount of energy it takes to produce the stuff in the first place plus the usual storage and transport problems. |

Hydrogen cars are like nuclear fusion generators. They're always 10 years away. Even in the 90s, hydrogen was the wonder fuel that we'd all be using. We're 25 years later and haven't really made significant progress in this. In the amount of time that hydrogen cars have made very little progress, EVs have gone from nothing to being produced by all major vehicle manufacturers. Battery tech has gone from a little bit of extra range on a hybrid to over 300 miles. Charging has gone from 12 hours to an hour. Whilst EVs are not there yet, they're making far more rapid progress than hydrogen cars have. Hydrogen has several major advantages, but by the time that tech is ready, we'll already be on EVs anyway. It has no advance at a decent rate because otherwise, it's too late. By 2030 EVs will have taken over. And with renewable energy systems requiring battery backups, we're finding all sorts of good uses for ex-EV battery packs too. |

You're assuming that mine was correct!! Seriously, I think that for the rest of my natural, hydrogen fuel cell - hybrid is the way to go. If I was younger, well funded and fully motivated, I'd open a hydrogen filling station. |

Since the explosion at a Hydrogen filling station in Norway last month , [ there has been one in California also ] , all of the Norway stations have been closed & the Hydrogen powered cars have been withdrawn .
As well as the explosive nature of the fuel , there is the , [ already mentioned ], fact that it is not very energy efficient in production & use , it is very difficult to stop it from leaking , [ being ultra low density it will actually seep through steel ] & because of the low density requires very high pressure to have enough capacity to be of any use as a fuel . To have any sort of range , a car will need over 5000 PSI in the tank , which leads to lots of problems with fuelling & storage . So will probably never meet the needs of normal motoring . |

I am actually working on the next generation of power plants, does anyone else want to invest a few quid with me ?Clockwork.jpg Joking aside a guy that lived across the road to me in the UK used to manufacture clockwork starter motors that he used to flog to 3rd world countries.

I think that the fact that hydrogen cars are always "10 years away" is not really due to any limitation in technology; I'd say there are two, very simple answers.
The first one is that hydrogen is very volatile and inflammable, if not explosive. If we're talking about cars that use it as fuel (as opposed to hydrogen fuel cells), then, a car that gets into an accident could turn into a bomb, which is a danger not only to the driver and passengers of that car, but to everyone around as well. The second is, unfortunately, the heavy lobbying of the fossil fuel industry, that blocks or, at least, slows down most advances in alternative power sources for personal cars. |
