Good, Perfect, and Real Carbon Targets – Finale

By Energy Rant No Comments
In this week's Energy Rant, we're covering the final segment of good, perfect, and real carbon targets. There are two sources of carbon-free energy. First, we have the category of renewable with wind, solar, hydro, and some geothermal. Second, we have nuclear. Oops – third, we have efficiency and demand management. The electricity market is bizarre to me. Last week I crudely explained how the regional transmission authorities (RTO) and their twins, independent system operators (ISO), balance the grid in real-time. Power supplied must match demand with very tight tolerances of voltage and frequency at all times. The chart below...

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...

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...

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...
