Even in Water gas Shift reaction, you do need a catalyst and It generally is Fe3O4- Cr2O3 and further more both WGS and SMR are 2 completely different reactions
So basically all the hydrogen fuel they make for these green cars produces co2. Ya know. Cleaner than an EV for sure. Btw. The second reaction happens naturally as carbon monoxide isn’t very stable. It reacts with the water in the atmosphere to create co2
hydrogen derived from electrolysis of water is "green" hydrogen, from fossil fuel is "grey" and from natural gas through steam methane reforming as explained here is "blue" hydrogen
A question. I read an article claiming that methane on farms could be made into hydrogen to power a cell and that would be more efficient use of the energy than burning the methane in a combustion engine. Is this reliable? Thanks for a very informative video. I'm no chemist though but I almost understood I think. Much thanks to the visual explanation with that formula.
@@caomilo1031 Exactly. At the end of the day, you're producing energy from methane + carbon dioxide, which is a greenhouse gas but has many methods in regards to its transport and storage. However, if fuel cells are not used, instead of having energy+CO2, methane would be produced and released to the environment, which has a higher heat capacity (provides more heat to the atmosphere) and lasts more in the atmosphere than CO2. Ultimately, you're highly reducing the pollution of the farm, but not mitigating all of it.
thats really interesting! im only an undergrad student, so def take what i say with a grain of salt, but im curious how practical it is to actually collect methane released on farms from the atmosphere in order to harness it. Otherwise it seems like a good potential use of a waste product. After all, in an ideal world we should all be trying to make systems more circular, and move away from a more linear waste = waste approach
@@FranciscoGaribayP Unless the energy used to create the steam is from renewables isn't that energy going to make this more polluting than just burning the methane?
@@Pegaroo_ As you mention, it depends on the energy source you use. Ideally, renewable sources would guarantee the greatest reduction in emissions. However, even if you use fossil fuels (natural gas, fueloil, coal) it is preferable than burning the methane because they release CO2, NOx and SOx. If you directly burn the methane, biogas could be produced, however it is highly-energy inefficient and H2S is released during the process.
I think that you mean separate and the separation process could use some form of capture. Other methods are available possibly osmosis through a membrane as hydrogen will move much faster.
My junior try to prepare a hydrogen (H2) for fuel cell. I don't know exactly how is this prepared, costing and etc. I just read some articles in Google. Lot of methods are there for preparing a hydrogen. I just need is this method I mean, hydrogen preparation with methane is effective or not sir.

Water-gas shift reaction takes place in the converter inside Steam Methane reforming unit, it uses iron catalyst.
Even in Water gas Shift reaction, you do need a catalyst and It generally is Fe3O4- Cr2O3 and further more both WGS and SMR are 2 completely different reactions
great explanation!

Near Petroleum city they marked the lot to build the new H2 plant from scratch.
I don’t understand. Do you have a link ?
Did you miss the part where this produces CO2?
hydrogen derived from electrolysis of water is "green" hydrogen, from fossil fuel is "grey" and from natural gas through steam methane reforming as explained here is "blue" hydrogen
Difference?

Methane reformed fuel cell will be much more efficient than burning methane via combustion engine. Plus less pollution.

Thank you a lot
Thanks uncle ji
That was awesome, thanks foe sharing!
I’m not a chemist but how practical is it to use a catalyst to convert liquid ammonia (NH3) to hydrogen on demand as a vehicle fuel?
What is the most feasible way to produce hydrogen ??
Liquid water and hot Methean could yield the same result ?
i believe he said that at a high temperature, like 1000c yes, unless im mistaken
it should be under higher pressure or low?
What are methods that used to capture CO2 from Hydrogen?
Install a vent at the floor to collect CO2,as hydrogen is much lighter than CO2 it won't mix up with the CO2 at the bottom
I think that you mean separate and the separation process could use some form of capture.
Other methods are available possibly osmosis through a membrane as hydrogen will move much faster.
Flowing the hydrogen and CO2 gas through an amine absorber will remove the CO2 and provide nearly pure hydrogen

How to work catalyst Ni on alumina
thanks
Nice
Very nice
