This article is a companion to my recent article about why I think battery electric trucks are the future of freight: Electric Trucks- the Future of Freight TL&DR: hydrogen trucks are largely just a retreat position for people who previously thought hydrogen cars were going to be a thing. They won’t be. There is no […]

E-Methane: Exergy Destroyer, On Steroids
TL&DR: grinding up electricity to make heating fuel is just a way to waste energy and capital, by destroying exergy (the potential to do thermodynamic work). It’s obviously worse than just making hydrogen. It is wasteful, and wasteful means expensive. It also means higher emissions than if you did something sensible, like feeding a heatpump. […]
Breakthrough in Electrolyzer Efficiency!
“FOR IMMEDIATE RELEASE This isn’t just a step forward; it’s a colossal leap towards a future brimming with sustainable energy! Our team of wizard-like scientists and technical magicians have unlocked the secrets of hydrogen electrolysis, achieving unprecedented levels of energy efficiency that were previously considered the stuff of dreams. The newly discovered process, affectionately dubbed […]
Scaling Example #2: Water Electrolysis
Scaling Object Lesson #2: Water Electrolyzers For Hydrogen Production We learned about vertical scaling in the 1st article in this series: …and about horizontal scaling or “numbering up” in the 2nd: Now we’ll use these tools to examine the scaling future of an extremely important decarbonization technology: electrolyzers for producing hydrogen from renewable electricity. My readers will […]
Are German Gas Pipelines “Fundamentally Suitable” for Hydrogen?
A recent study https://www.dvgw.de/medien/dvgw/forschung/berichte/g202006-sywesth2-steel-dvgw.pdf carried out by Open Grid Europe GmbH with the assistance of the University of Stuttgart, paid for by DVGW (Deutscher Verein des Gas- und Wasserfaches- the German Association for Gas and Water) did rather careful, extensive and thorough testing of a wide and characteristic variety of pipeline steels in hydrogen atmospheres of […]
The Myth of Hydrogen as an Energy Export Commodity
There is a popular myth in the marketplace of ideas at the moment: the notion that hydrogen will become a way to export renewable electricity in a decarbonized future, from places with an excess of renewable electricity, to places with a shortage of supply and a large energy demand. It seems that the hydrogen #hopium […]
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 […]
Blackish-Blue Bruise Coloured Hydrogen
My readers will know that I have never liked the “colours of hydrogen” that has been spread, as a meme, by the hydrogen-as-a-fuel lobby. There is only really one kind of hydrogen in the world right now. Hydrogen- 98.7% of it by generous estimate- is made from fossils, without meaningful carbon capture. It is barest […]
Waste to Energy/Waste to Fuels: the Great Greenwashing Machine
Most of us find waste to be viscerally repugnant. The smell and even the appearance of garbage revolts us. And yet we all generate it, in seemingly endless quantity. In “developed” (rich) nations, we therefore have built extensive systems to get this repugnant material out of sight, and hence out of our minds, as quickly […]
Hydrogen From Renewable Energy- Our Future?
Image credit: https://www.rolandberger.com/zh/Publications/European-cities-bet-on-hydrogen-fuel-cells-to-help-meet-emission-targets.html Is the image I’ve used, and credited above, a fair representation of our future? Hydrogen proponents, particularly those who want to sell us on the superiority of hydrogen as a transport fuel for fuelcell electric vehicles, would like us to believe it. But what would it take to make such a dream- the […]
