Battery power will NEVER do what Hydrogen can

In a continuation of an earlier debate..hydrogen fuel cells can power large vehicles such as heavy trucks, trains and ships..and hydrogen can be used to power aircraft.

THIS will be the wave of the future..wait and see, not those flimsy plug in EV 's. Zero emission clean hydrogen power.

Demolish the Hindenburg in a catastrophic explosion?

You have the perfect name. This can and I think will be the direction we go in. We will not eliminate fossil fuels, we need lubricants and oil is used in so many other applications besides fuels, but this is the way to go IMO.

Put a match to gasoline the same thing happens.

I’ll never understand why this hasn’t been the main push over electric, especially considering how green it is.

There are ways to store hydrogen that are relatively safe. It can be stored as a solid, complexed with aluminum for instance. I know for a fact that the military is researching this for their “battery” needs.

German Type 212 submarines. Primary propulsion is diesel-electric but they use hydrogen as a secondary means of propulsion.

Look up air-independent propulsion (AIP)

Although hydrogen–oxygen propulsion had been considered for submarines as early as World War I, the concept was not very successful until recently due to fire and explosion concerns. In the Type 212 this has been countered by storing the fuel and oxidizer in tanks outside the crew space, between the pressure hull and outer light hull. The gases are piped through the pressure hull to the fuel cells as needed to generate electricity, but at any given time there is only a very small amount of gas present in the crew space.

One question - where will all of this hydrogen come from?

For autos, hydrogen sucks. 95% is derived from fossil fuel. The production and distribution network would cost trillions to build. The vehicles are just as heavy as regular battery cars, the fuel cells and tanks are extremely expensive. And the hydrogen fuel itself is very expensive.

Battery vehicles are superior in almost every single metric, except refueling time. For the people who absolutely need to refuel quickly, gasoline and diesel are far superior to hydrogen in every conceivable way. Hydrogen will only exist as a viable alternative if fossil fuels are outlawed or taxed out of existence.

Hydrogen costs too much to use right now. It requires electricity to make it work anyway.

On our submarines we use electrolytic oxygen generators to make the oxygen we need to stay submurged. Basically takes pure water, zaps it with electrical current, and has cells that pull the H2 and O to opposing sides (cathode/anode).

We would keep the oxygen and pump the hydrogen overboard. I always thought it would be a great idea to save the hydrogen as well and develop some sort of secondary propulsion system that would run off H2... as a backup to the reactor.

Think of how many big trucks are involved in wrecks yearly. Now imagine all or most result in massive explosions.

Making chlorine from salt produces a shitload.

So much so if people can't offtake and compress at neighboring facilities it is offten vented to atmosphere and wasted.

Then there's the efficiency. Batteries store and release energy with minimal losses; for every kilowatt-hour your rooftop array generates and sticks into a battery, you'll get back more than 90 percent of it. But the process of generating hydrogen by electrolysis using a proton exchange membrane is only about 80 percent efficient, so you lose 20 percent straight away. And at the other end, you'll lose somewhere around half of what you've got stored in the process of converting the hydrogen back into energy through a fuel cell.


Converting hydrogen is much less efficient than a pure electric battery.
Hydrogen conversion\fuel cells are much bulkier, more expensive, and less efficient. Some EVs will be out this year with 500 mile ranges, and it’s infrastructure and tech is budding quickly. Comparing hydrogen to EV regarding personal usage the power grid requirements and practicality means hydrogen will have a lot of ground to make up. That’s not to say electric doesn’t have its cons, but it’s more user friendly.

In the near to mid future EVs will continue to dominate. Especially for personal use, hydrogen is just much less practical. Commercially for 18 wheelers and large businesses hydrogen may make more sense but it won’t overtake EV for personal use without some seriously disproportionate tech advances over EV.

You might wanna do some research bc your statement is false as frick

I wish you were right, but I don't see it.
quote:

The highly touted hydrogen fuel cells are not an energy source at all, but are more properly termed a form of energy storage. Free hydrogen does not exist on this planet. It requires more energy to break a hydrogen bond than will ever be garnered from that free hydrogen. The current source of hydrogen is natural gas – that is, a hydrocarbon. In the envisioned system of solar PVC & hydrogen fuel cells, every major component of the system, from the PVC to the fuel cells themselves will require hydrocarbon energy and feedstocks. The oil age will never be replaced by a hydrogen fuel-cell economy.16
