Over the past year or so, as the hydrogen for energy hype bubble has started to leak badly, a clear indicator of the end times for hydrogen energy proponents has started to emerge, anger and hostility. Why is this a clear indicator? Let’s cast our minds back eight years. Sometime … [continued]
About 25 years ago, hydrogen was the solution of choice for climate-aware technocrats and politicians, and with good reason. At the time, there really wasn’t much choice in terms of low-carbon energy carriers. Batteries were good enough for laptops and phones, but clearly no one was going to be running … [continued]
Over the past year or so, energy return on energy invested (EROEI) has shown up multiple times for me as an attack on technologies that are now superior. A nuclear shipping advocate tried to gotcha me with that for biofuels for shipping. Others reasonably asked about it for biofuels in … [continued]
Carbon capture and sequestration in all of its various ineffective, inefficient and expensive forms is having another run up the hype cycle. Nothing has really changed. The problems still exist. The alternatives are still better. The potential for use is still minuscule. And so, the CCS Redux series, republishing old … [continued]

Green hydrogen is absolutely essential for decarbonizing the massive global warming problem that is current hydrogen use. Our current 120 million tons is a global warming problem on the scale of all of aviation. You would think that fixing that would be the highest priority, and that deeply irrational alternatives … [continued]

Many power-to-x firms and energy exporting companies are looking at Japan especially, but also other hydrocarbon light countries as a great market to send ammonia to as an energy carrier. That’s not going to end well. Why not? Let’s start with ammonia itself. It’s hydrogen and nitrogen. The nitrogen doesn’t … [continued]
Recently I’ve been reviewing studies related to hydrogen trucking, as it’s one of the few places where serious transportation research organizations still hold out hope for the energy carrier. I’ve looked at studies from multiple countries in Europe and North America back as far as 2010 now. Most recently I’ve … [continued]
One of the interesting things I’ve been doing is participating in a review group for a European study on heavy vehicle decarbonization comparisons and simulations. That means, among other things, that I’m poking at the assumptions being used. As the paper is in review and assumptions are being tested and … [continued]
