The Thing About Hydrogen - Part 2.


Transcript:

So, we looked at the hydrogen that is bound to oxygen, and we saw why that might not be the answer. Let's look at the other one—the hydrogen that is bound to carbon. Now, you can get hydrogen from methane by steam reforming it. And that's how most of the hydrogen is produced: by steam methane reforming. The problem is when that carbon gets liberated, the oxygen bounds to it, and then it makes CO2. 

Now, if we can put a cap around this whole process of steam methane reforming, so that the emitted CO2 doesn't go to the atmosphere, but it goes down whole. And if we can do that by not increasing the net carbon footprint but actually significantly reducing it, then we have a source of hydrogen that can be potentially used as fuel. Except the other side: the recombination or the splitting of the hydrogen and combining it with water, I mean combining with oxygen to make water in an electrochemical cell, that process efficiency is not high enough. 

So, the hydrogen economy is a low-hanging fruit. We have to do something. So that's the easiest thing that we can do. But, long-term, that is not the answer.
