As the world races toward a decarbonized future, hydrogen is often touted as a clean energy carrier, with proponents highlighting electrolysis as a viable method for its production. The process, which uses electricity to split water into hydrogen and oxygen, can indeed be powered by renewable energy sources, making it … [continued]
The Texas-based startup Utility Global is offering a reactor-based, non-electric, hydrogen-producing blast furnace waste gas conversion system to the global clean steel movement.
Saying hydrogen is abundant is like saying gold is easy to get—it’s out there, but extracting it is hard, expensive, and energy-intensive. The problem isn’t scarcity; the problem is accessibility. Hydrogen advocates often parrot the line that hydrogen is the most abundant element in the universe, implying that it’s naturally … [continued]
Recently I published a simple debunker for many of the hydrogen for energy claims that perpetuate the hype, Cranky Stepdad vs Hydrogen for Energy: How to Respond to Enthusiasts. In the style of John Cook’s Cranky Uncle vs Climate Change — illustrative cartoons and colorful analogies illustrating the debunk — … [continued]
Hydrogen for energy has been the subject of extravagant claims for decades, and they keep being repeated. When you run into a hydrogen for energy enthusiast and they start saying things that make it seem as if hydrogen for energy is a slam dunk, have a look through this. Some … [continued]
Artificial intelligence is often criticized for its energy intensity, with large-scale models like GPT-4 consuming tens of gigawatt-hours during training. However, it’s important to place this within the broader context of energy consumption and AI use case trends. I published a couple of times on demand to provide context, and … [continued]
At Ponderosa High School in Coconino County, Arizona, students are determined to overcome obstacles on their path to graduation. Some arrive behind on credits, while others are returning to the classroom after time away. The alternative school offers more than a second chance—it is an opportunity for transformation. That is … [continued]
I just tried my best to introduce and share Kia’s new PV5 and its overall PBV concept. At the heart of the PV5 and broader PBV platform, though, is going to be Samsung internet of things (IoT) software. The last big announcement from 2025 Kia EV Day is about this … [continued]
One of the privileges of creating content for an independent media source is reporting the good news about clean energy and energy efficiency. Otherwise, it tends to be unreported or overlooked although it is happening and does exist. Years ago, someone told me that solar power for homes was too … [continued]
The Energy Star energy efficiency program is a valuable marketing tool for builders, appliance makers, and other stakeholders, and a reliable source of information for consumers.
