S6E15 - Is Turquoise Greener than Green? - a podcast by Antoine Walter

The greenest Hydrogen is Turquoise.

Hydrogen is not the sustainable gas you probably think it is. Today, 98.7% of the hydrogen used in the World is produced from fossil fuels without carbon capture.

This means it would have exactly the same carbon impact as the coal or gas it's made of... Well if production processes were 100% sealed and reliable, which they're not.

In fact, today, hydrogen is not a decarbonization tool; it's a decarbonization problem!

To solve it, a colorful array of hydrogens intend to replace the traditional blackish one. 

We have, for instance, blue, which captures the carbon, or green which removes carbon from the equation by producing hydrogen from water. 

The problem is that thermodynamics is quite bitchy, and it decided that this process would always be more expensive. 

Bad, bad physics!

But there's a last color that could save the day: turquoise. It leverages pyrolysis of methane to produce hydrogen and graphite and can even be conducted directly on wastewater treatment plants.

See, I'm not colorblind, in fact, the greenest hydrogen is turquoise!
