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 […]

Why Can’t Batteries Store More Than 4 Hours of Energy?
TL&DR Summary: they can. But the economics of energy storage depend on the application, and no energy storage option makes cheap kWh unless it is used to deliver enough kWh. Long term storage must have an ultra-low capital cost to be affordable, because otherwise its cost is not distributed over a large enough number of […]
A Short Screed About Biofuels
Apologies to the millions of artists whose work was scraped by Google to make their generative AI tool possible. TL&DR Summary: we’ll need biofuels for shipping and aviation, which need rather than merely want liquid fuels. We’ll also potentially need biofuels to serve as our reservoir of stored fuels to serve periods of renewable electricity […]
Green Hydrogen as a Fuel is a Zombie Meme Idea
TL&DR summary: hydrogen as a fuel is a zombie idea. Thermodynamics and the properties of the molecule ensure that it will never be alive in economic terms. Hydrogen’s dirty present hasn’t meaningfully changed over the last 20 years, and hydrogen as a fuel isn’t a real decarbonization idea. However, while it will never be alive, […]
Electric Heating- the Future of Industrial Heat

The reality is more complex. The reason we use fire to make heat is that […]
Home Heating-Electrification?
UPDATE 17/08/2024: major updated costs and analysis Warning: this article contains a lot of numbers. Numbers that tell a story. If you don’t like numbers, stop reading and spare yourself arithmetic anxiety. It should not be news to you that people in Canada need to heat their homes. Some of us also need air conditioning […]
Ammonia- “Ship of Fuels”? or Fuel of Fools?
image credit: Microsoft Create TL&DR: ammonia is a toxic and corrosive gas, and using it as a fuel aboard ships fails the 1st principle of safety in design. It is an insane idea, and those pushing this toxic idea should give their heads a serious shaking. I am a chemical engineer with many decades of […]
Where Does Green Hydrogen Fit?
Image credit: Google Gemini If you know my writing even a little, you’ll know where I stand on this issue. It’s as simple as my meme, but my many articles (especially this one) explain why, in detail. Those articles come with analysis and references and the comments of many experts in the field as an […]
Yes, Virginia, Solar Really is THAT Cheap!
TL&DR Summary: yes, it really is that cheap. It’s not bullshit. It’s real. And it’s going to power the world. Well, not the whole world- but a very significant part of the world. Those of you who read my articles will know that I have a small farm east of Toronto. We’ve built a couple […]
The Refinery of the Future
photo credit: Google Gemini TL&DR: we will continue to refine petroleum to make the chemicals and materials we need in a decarbonized future. We’ll just do it without the burning. It will be complex, expensive, and will take a new kind of refinery which looks quite different than today’s refinery. You’ve no doubt heard the […]
