Are hydrogen fuel cells efficient?  I don’t know anything about them

The primary problem with Hydrogen is storage and transport.  Steel tanks look like cheesecloth to Hydrogen.

Think about it, from what do you fabricate a container for the smallest of all elements?

Some light reading on the state of the tech https://hackaday.com/2019/09/04/are-hydrogen-cars-still-happening/

The Hindenburg was able to hold some hydrogen.  I am confident the tech has evolved since.

Sorry Hairy, but that comes off as hand wavey.  

Hydrogen has decent energy density by weight, but very poor energy density by volume.  The Zeppelins were very low pressure propositions.  In order to carry a useful amount for fuel use in an acceptable volume very high pressures are needed, something on the order of 700bar.

Trust me, this is a real problem.  There are solutions, but as always these too come at a cost.

I don’t claim any knowledge of hydrogen as a fuel.  

Can you just liquefy it?  That’s how LNG is shipped across the ocean.

As for the issue of energy, we have gone crazy, we produce tons of products that are not consumed, globalization is fine, but to some extent.

Now everything that is bought is thrown away in a few days, months, shirt, pants, shoes, not to mention the planned obsolescence, nothing is built as before, everything is designed to stop working in x days

Apart from this, it would start by eliminating low-cost airlines, this if it is a waste of energy and a great focus of pollution.

Doomed to see the future and unable to prevent it
Maybe those protesters should all go to China and protest their policies, until China changes its policies, it doesn't really matter what any other country does.

For some reason the so called "environmental" people never actually call out or confront China, quite interesting.

Brilliant logic you have there, the neighbors are poisoning their ground water so we should help it along by poisoning our side as well and just to distract from the fact that we don't want to make any sacrifices lets point our fingers at them.

That'll teach them!


Thx by the link.

Trying to reclaim the 200DMA ($8375 at the moment)? Need a 200 bucks pump. Yesterday's green candle created some hope.

Go above the 200DMA and the bull run can continue. If we can't soon, there will be a problem. Buy you fools. If you aren't gonna, at least don't sell you fools.

^Again, it has nothing to do with storage, it's that segregation of hydrogen is a net negative energy reaction (unless one of the spooks reading this thread would like to post a classified method I don't know about).

Before anyone brings up some Bob Lazar hydrogen bullshit, I've never really looked into any of 'those people's' claims and just assumed they were all fake because of the whole Area-51, UFOs, aliens, and other stuff he talks about. The Jewish occupied govt seems to attempt to jail, kill, blackmail, or frame people for far less than anything he talks about if it was actually true.  Both (((climate change))) and aliens are also mentioned as schemes to try and exert control over the population WAY back in the 60's in Report From Iron Mountain.

Protesters filled the streets of Montreal today with Greta in solidarity to fight climate change.  Sadly, government measures will be regressive and likely a heavy finacial burden on the no-coiners.  How long will it be before the same people begging for climate action in Montreal don yellow vests to protest the taxes they are begging for today?
 We managed to fix the ozone problem with a cfc ban.  We managed to fix the acid rain problem with some technological advances.  I have no doubt we will remedy the climate change issue but the longer we wait, the more painful it will be financially speaking.  Another global recession would do wonders for the climate issue.  It's likely the only way China's and India's CO2 emmsiions are going to be significantly lowered in the near term.  Not sure how long we really have before there is no recovering.

Soon we'll be making graphene from CO2 for use in graphene/graphene oxide hydrogen fuel cells.  Global warming crisis averted.

Apparently you didn't read my previous post where the root of the problem is the segregation of hydrogen is a net negative energy reaction and doesn't really have anything to do with fuel cells.  But there is no "global warming crisis" anyway.  It's a scam from psychopaths who - just like how they use communism for the same purpose - as an excuse to try and centralize all power and rule over everyone as slaves.  This scheme is mostly orchestrated by psychopaths from the evil cult of Judaism who believe it's their manifest destiny to rule over the 'goyim' with goyim being their servants to abuse.

Hydrogen will probably be the future in some manner just due to the simple fact it's the most abundant element in the universe while also being an energy source.  The problem is that the environment pre-segregates other fuel sources like oil or wood for you where you can just pick it up and set it on fire to generate energy, while you have to spend energy to segregate hydrogen to turn it into fuel.

Turning water into 1 kg of hydrogen with electrolysis uses 39 kWh of power, while the 1 kg of hydrogen is a 33 kWh metastable energy source.  It's a net negative reaction in otherwords.  That is not to say the hydrogen is useless.  It gives you 33 kWh of portable power vs 10 kWh or so in diesel.  It sounds like miracle fuel until you take into account it takes up an enormous amount of space unless you spend large amounts of additional power to liquify the hydrogen, while also being a net negative energy gain with oil being a positive energy gain.

Even though hydrogen creation is a net negative energy reaction, if you utilize 'free' energy to create it (i.e. solar, geothermal, dams, etc) then it becomes somewhat useful again solely as a portable energy source for vehicles.  Unless you can lower the friction to creating hydrogen to be net positive instead of net negative, it seems like it's main application is solely vehicles where power density of fuel is one of the main concerns, otherwise you would skip the generation of hydrogen and use the solar, wind, nuclear, or dam power directly.  If battery storage got exponentially better, you would then also skip hydrogen generation completely and send the electric power straight to the batteries too.  So hydrogen power is currently mostly based around the idea of batteries always being bad.

we may start running out of CO2 due to the coral.
This is not possible. Nature is a self-balancing system. More plants more oxygen more animals, and a new balance is eventually reached. Of course, if people actually believe we need more co2, well, we have a solution for that.
