Electrified Heating without Breaking the Grid or Bank

By Energy Rant No Comments
Here are my last words, for now, on artificial intelligence: I do not claim to understand the computations or systems behind AI whatsoever. However, I do understand human behavior very well, so when I saw a headline last week, JPMorgan CEO: AI Will Eventually Lead to 3.5-Day Workweek, my response was, never, not going to happen. I mean, people will not be compensated with 40 hours of pay for 28 hours of work. That is fantasy. I remember dispelling such fiction as a grade schooler because the same concept was floated back in the 1970s. Only the mode of automation…

Electric Utility 2050

By Energy Rant No Comments
As we prepare to take our energy storage solutions to market, I gathered recent news reports, analyzed them all, and came to some conclusions. I concluded that utilities, and especially regulators, need to think differently. What got us here – constant load growth and earning returns on conventional rate base by building power plants, transmission, and distribution systems – will not get us there (the energy transition) without turmoil and upheaval. Sign up for AESP’s decarb course to learn more details. Public service commissions get 50% off. Why? Because they must know this stuff. Nothing Lasts Forever Like everything, the…

COP27, Elites, and Engineers

By Energy Rant No Comments
I have run enough marathons to have lost count, most of them in the last ten years, with the total approaching 20. Why would you do that, Jeff? I like the grind, double, especially when I can run negative splits and pass people the entire race rather than being passed the whole race. I’ve done both about equally. I guessed that winning marathon times had not changed much in forty years. Wikipedia confirms this with finishing times at the NYC marathon. Americans Bill Rogers and Alberto Salazar finished with the same times back in the 1970s and early 1980s as…

Leveling the Skateboard Curve with a Demand Side Attack

NERC sounds alarm on solar tripping in sobering summer reliability report, May 19, 2022, UtilityDive.com. This seems like a timely sequel to last week’s Blistering Wind and Solar Energy post, in which I summarized the results of a renewables integration study performed by the Midcontinent Independent System Operator. The blisters represent pockets of excessive renewable energy generation and the “very different reliability risks than are experienced today,” as described in the MISO report. Electronics provide voltage and frequency control from solar panel generation. When the solar tiger grows from a cub that we had a few years ago into the…

A Franchise Organization for Decarb

By Energy Rant No Comments
About every six months, while participating in a strategic planning, leadership, marketing, or business development meeting, I hear “we should be doing decarb,” or “we’ve been talking about decarb for years, and that’s all we do is talk about it.” “We’ll be right back here talking about it a year from now.” Whoa! First, what is decarb? My guess is most people would say reducing the consumption of hydrocarbons in a catalytic process with airborne oxygen to produce heat which may be used for heating, power generation, or locomotion – while producing coproducts of gaseous water, carbon dioxide, and minuscule…

Good, Perfect, and Real Carbon Targets – Part 3

By Energy Rant No Comments
In this week's Energy Rant, we're covering part three of good, perfect, and real carbon targets.In Part I of this series, we examined how various storage technologies work, their pluses, and minuses. In Part II, we put numbers to generation and storage technologies, including maximum power, duration of discharge (for storage), cost per megawatt and megawatt-hour to build and operate, and a slew of other great stuff. In Part III, we will size up the numbers from Part II to actual grid demand. The objective is to provide scale to see what we would need to pair high percentages of…

Good, Perfect, and Real Carbon Targets – Part 2

By Energy Rant No Comments
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 to float the Hindenburg. Hydrogen, while very light, is explosively combustible, so putting it in a blimp was crazy. I always like to throw factoids in for budding STEM enthusiasts. Take a helium (non-combustible) balloon on a string, hold it by the string in a moving vehicle.…

Good, Perfect, and Real Carbon Targets

By Energy Rant No Comments
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, with no background in the subject, declare that “we” (state, city, etc.) will be powered by 100% renewable energy by 2050. The universe is between here and there. When I hear that renewable electricity is cost-competitive with conventional sources like combined-cycle natural gas or even…

Phase Change Materials for Grid-Interactive Efficient Buildings (GEBs)!

By Energy Rant No Comments
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. The simplest everyday thermal storage material is ice. Grocery and convenience companies have enormous ice-making facilities for guess what: thermal storage and your lowly Igloo or swanky Yeti coolers. I have a Coleman Lil Oscar cooler that I’ve used since Ha School. Now that is…

Thermal Storage for Grid-Interactive Efficient Buildings

By Energy Rant No Comments
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 and keep us cool in the summer heat. Like water, practically anything will freeze, melt or vaporize. Take copper, please. It is widely used to conduct electricity in homes and buildings. It too melts and vaporizes. When it vaporizes, you don’t want to be near it…
