Hydrogen Car

A video by the Lawrence Livermore National Laboratory (LLNL), California, USA regarding an experimental hydrogen car.

Source- https://publicaffairs.llnl.gov/news/video_archive.html

'A cryogenic pressure vessel developed and installed in an experimental hybrid vehicle by an LLNL research team can hold liquid hydrogen for six days without venting any of the fuel. Unlike conventional liquid hydrogen (LH_2) tanks in prototype cars, the LLNL pressure vessel was parked for six days without venting evaporated hydrogen vapor. The LLNL development has significantly increased the amount of time it takes to start releasing hydrogen during periods of long-term parking, as compared to todays liquid hydrogen tanks capable of holding hydrogen for merely two to four days.'

bad thing about hydrogen is its so dangerous. anything goes wrong that car is going to blow up sky high

[Killerx141]

Not much diff from a gas explosion

I heard you Buddy, but I think there is no such thing as blastproof material against the mighty power of hydrogen.The only thing you can do after the explosion is say the prayer called " HASTA LA VISTA BABY"

i woudnt step foot inside that thing unless they stored the hydrogen in like a blast proof material but still risky...

[HHOhybridBuilder]

That's right, even your soul will be disintegrated upon explosion.

[williepie]

true if you got in an acceident and it bursts open and theres a spark BOOM thats one of the cons haha

Very nice technology and efficient. I admire it but still I won't buy these type of cars because for me it is very annoying to carry a hydrogen tank behind a car. I will be very scared of it.

for cars, rechargeable batteries are better, thats clear.

the problem is that lithium ion technology doesnt scale well. when it comes to the amount of energy you can store, hydrogen technology in combination with a former natural gas pipeline system or a huge underground cavern that can be filled with it would allow for a considerable scale.

you just cannot store the amount of energy a powerplant produces in 1 week with rechargeable batteries, its not an option.

The use of the syngas processes is used today to create hydrogen for industrial uses. I'm sure that the numbers have been crunched, and the companies have found that the electrolysis is a bit more expensive. As well the electrolysis of water is about 50% efficient, while the charge/discharge efficiency of a lithium ion battery is about 80%-90%. The question is whether or not hydrogen is a more viable way to store energy then a lithium ion battery, I would presume the latter.

second comment to hellgas0 :

but it really doesnt matter. there is no reason for the big corporations to get active here, as long as noone complains about the coal power plants and about the fact that the energy we use for whatever technology comes from fossil fuels.

hydrogen is no threat for them as long as theres so much coal energy in the electrical grid. no reason to try to directly turn coal into hydrogen WHEN ITS ALREADY HAPPENING AND HAS BEEN FOR DECADES in an indirect way.
