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 comment on hydrogen was its use as a buoyant gas toRead more

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 always, “Yes, it’s just a matter of money.” That led me to briefly discuss politicians,Read more

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 a week a month, he’s never gone.Read more

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, including space conditioning, food storage and transportation, healthcare, manufacturing, and of course, thermal storage.Read more

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 last 150 years, give or take, to generate electricity, refrigerate, freeze andRead more

The batteries are coming! Maybe. I recently participated in an EPA-sponsored webinar to explore the results of a couple of case studies of lithium-ion batteries used to shave and shape building electrical loads. The technology is more nascent or even embryonic than I would have guessed. Interestingly, I’ve read a lot about systems approaches toRead more

Distributed, independent, economical, efficient, reliable, resilient, flexible, adaptable, technical, clean, redundant, modern, profitable, renewable ready, and doh, smart! What is this? A microgrid? No, it’s Michaels Energy. We’re back[1]. The Rant is back, and we’re ready to rock and roll! Let us take a look back a year and briefly review what has progressed inRead more

I’m not in the electricity storage business, but I can recognize lousy ideas when I see them. Grid-scale battery storage is a bad idea. It will never be anything more than a frequency and voltage regulation technology, although I have to say these are critical functions that batteries can provide. Innovation comes out of leftRead more

I’ve been doing a lot of program impact evaluation for the last few months. That comes with pluses and minuses. One of the minuses is that I needed to suspend writing this blog for a while. Pluses include problem-solving, working with staff throughout our company, and forensics engineering. Impact Evaluation But first, what is impactRead more

A few weeks ago, I observed a webinar [1]sponsored by the Advanced Energy Economy to help me triangulate what the next great trend(s) might be. That meshed well with the electric vehicles (EV) post of last week and this week. The webinar featured two electrification apostles and two critics. The apostles led off with theRead more

The electric car (or vehicle / EV) may be the most captivating technology of my career. I panned EVs ten years ago with a Frivolous Novelty[1]. I implore you to go back and read that. Almost nothing has changed in ten years! The iPhone launched 13 years ago. Everyone has an iPhone or an iPhoneRead more

God, it’s great to be back writing again. On that note, here is a quote, “There’s an old saying: Everyone wants to go to heaven, but no one wants to die.” I’ve been under a rock all my life because I had never heard that one. It’s the opening line to this NIMBYism and gridRead more
