As far as I understand the enregy used is electrical energy. So I fail to see the "catalytic" effect they write about. It's an electrode material progress and allows the splitting of water without use of added protons. But I doubt that it is more effective in moles hydrogen per kWh of elecricity than the current process.

[b]Exactly. Electrode material is not seen as catalysts in nost texts.[
There was also mention of the conversion being near the absolute minimum energy required for this conversion.
If true, it would also impact the hydrogen economy of transport, solar aside, because it uses electricity so it doesn't matter what you use to generate that power, nuclear, wind, solar, fossil, wave, geo-thermal, whatever.
It is claimed to be a breakthrough precisely because it is not in a textbook.

Originally posted by CRMCI was just watching a discovery channel program on that and I think they said something like 6 billion tons or thereabouts. That's a lot of vaseline!
Not sure if I'm in the right forum here, but can anyone tell me, in round terms, and in tons, or tonnes, how much oil has been mined from from this planet since commercial oil drilling began ? Say even from 1850 to date.

But it certainly belongs to the Science Forum. A very interesting question.
You got the answer: 6 billion tons, right or wrong.
How much is this? Say that (in the name of easy calculation) we have a density of 1 ton per 1 qubic metre. That will be a qube of oil 2 kilometre in height.
Excercise: If we pured it out on the surface of the earth, how deep layer would we have in average?

But, on the other hand, if we spill out all oil, then it would flow downhill to the sea level, so perhaps, realistically, the water surface perhaps would be better choice.
So an answer, a motivation, and proper units would give high points if I were to be your teacher.
