In this week’s Energy Rant, we’re covering part two of good, perfect, and real carbon targets. Last week we looked at grid-scale energy storage options for a couple of them, namely hydrogen and flywheels; I asked, “What could go wrong?” To be fair, my...

I recently delivered an electrification presentation for Wisconsin Public Utility Institute’s Energy Utility Basics course. While introducing myself, I said, “I’m an engineer, and I can’t help it.” I also said the answer to the question, “Can we ___?” is...

Way back in April, I had generated a list of non-energy benefits of the COVID. One was the lack of traffic. That made driving easier and running a little safer with less hassle. Second, my, uh, wellness trainer stopped making trips to Europe, so rather than being gone...

Last week in Thermal Storage for Grid-Interactive Efficient Buildings (GEBs), I introduced the importance of phase changes from solid to liquid to vapor, and the reverse, to our modern world. Benefits include heating, cooling, and refrigeration for all types of uses,...

Aside from efficiency being a core component of my thermos-fluids courses in engineering school, phase changes were also captivating to me. Phase changes from solid (ice) to liquid (water) to vapor (steam) have been used for hundreds of years, and more recently, the...
