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, […]

Green Steel = Green Iron
Image credit: Google Gemini What is “green steel”? Simple. It’s a misnomer. Iron in nature is rarely found alone. We mine its oxides as iron ores. These oxides need to be chemically reduced (gaining electrons = reduction) to take the Fe+2 and Fe+3 ions in the iron oxides, to Fe metal. And the oxygen needs […]
Will Green Hydrogen Save the Cement Industry?
Image credit: Google Gemini TL&DR summary: hydrogen can be used in cement production as a natural gas replacement, but that doesn’t solve the entire CO2 emissions of cement production. There are other problems like the lack of hydrogen flame radiance, but the deal killer is the cost per tonne of CO2 emissions averted. Hydrogen may […]
The ER-6: An Electrifying Conversion
UPDATED: 05/12/24 Those of you new to my articles may not know the beautiful and sad story of my previous conversion, my beloved Triumph E-Fire. Its told here in detail, from prehistory to its sad end…https://www.linkedin.com/pulse/e-fire-triumph-spitfire-ev-paul-martin/ This is the story of a resurrection- an electrifying conversion! In spring of 2019 I bought a 1973 Triumph […]
Can You Put Hydrogen in Natural Gas Pipelines? Ya, but…
Ya-but the rabbit, courtesy of Google Gemini TL&DR Summary: sure, you can re-use an existing gas pipeline to carry some quantity of hydrogen at some pressure, and do so safely. How much pressure and under what circumstances and operating conditions, and how much energy can be delivered via that repurposed pipe, and whether or not […]

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 […]
