“7000 H2 molecules every hour”

If I remember correctly, Avagadro’s number is 6.02 x 10^23 and the molecular weight of molecular hydrogen is 2.

So IIRC, it takes 9,800,000,000,000,000 years with this apparatus to make 2 grams of hydrogen.

When combusted, 2 grams of hydrogen would yield about 219 Btus, which is not enough to boil a gallon of water.

Doesn’t seem too impressive to me.

Indeed, the number is meaningless without telling us how much catalyst was producing it. Now, if they meant 7000 H2 per hour per catalyst molecule, that would be gangbusters.

This is still basic research. Wait till they get this perfected and scale up the surface area. Then it's free energy that can be compressed into tanks.

Catalyst chemistry is still a work in progress. The platinum used in a car's catalytic converter adds thousands of bucks to the cost, IIRC. Platinum and palladium are used in many industrial catalysts. The costs of many products can decrease if they can replace such expensive catalysts.

By my quick calculation, the process would have to be scaled up by a factor of 860 million billion billion to get one kilogram of hydrogen. Sounds like a challenge. When they put together a processing plant big enough to provide hydrogen to drive a single two passenger vehicle 100 miles every day - then they get to brag.....unless that 100 miles costs them more than my current commute.
