Image produced by generative AI, using the stolen works of millions of artists. TL&DR summary: CO2 is a low Gibbs free energy product of energy producing reactions. That fact makes it a thermodynamically unfavourable feedstock from which to make more than a handful of useful chemicals. The notion of widespread use of CO2 as a […]

Blue Hydrogen Reconsidered?
TL&DR Summary: blue hydrogen will be cheaper than green hydrogen for the foreseeable future. But the risk remains that the product will be much cheaper if we ignore the fact that it’s not blue, but rather blackish-blue and bruise coloured due to methane and uncaptured CO2 emissions. But that can also be said about green […]
Why Direct Air Capture (DAC) Sucks- and Not in a Good Way!
UPDATED January 15, 2026 and August 8, 2023 You’ve likely heard the sales pitch before: What am I talking about? Direct air capture- the act of using active mechanical/chemical equipment and vast quantities of renewable energy, in a totally pointless fight against entropy, to try to suck CO2 out of the atmosphere for either durable […]
Blackish Blue Bruise Coloured Hydrogen Part 2: the Ghost of Blue Hydrogen’s Future
Blackish-Blue Bruise Coloured Hydrogen Part 2: The Ghost of Blue Hydrogen’s Future As we found in Part 1, conventional hydrogen production from natural gas using steam methane reforming (SMR) coupled with carbon capture and storage (CCS) is easily written off as a waste of everyone’s time and money. It’s fooling nobody. Because nearly half the […]
