Innovations in Grid Flex

By Energy Rant No Comments
Last week, I was fortunate to see this article posted on EnergyCentral.com: Demand Flexibility Is No Longer Nice To Have. “ is increasingly becoming a “must have” as networks around the world are moving towards high levels of variable renewable generation resources. The increased variability of renewables, notably wind and solar, results in frequent episodes of feast and famine when supply exceeds demand and vice versa. The result is wide swings in wholesale prices, from near zero and negative to very high levels reflecting the imbalance in supply and demand. Storage and exporting/importing the surplus/deficit are invoked to the extent…

The TRC Is Calling – Has Anyone Seen 1979?

By Energy Rant No Comments
Last week Michaels Energy delivered a webinar, Achieving Grid Resiliency with Thermal Energy Storage. There are about 70 gigawatts of refrigeration load in the United States frozen storage and chilled-water HVAC systems alone. That 70 GW does not include distributors like Sysco or U.S. Foods, grocery distribution centers like Walmart or Kroger, food manufacturers like Tyson or Nestle, grocery stores, convenience stores, or restaurants. Add it all up, and well over 10% of the total peak load in the U.S. is sitting there in bags, boxes, and buckets of food, waiting to be used as a flexible load-shifting and management…

Smart Renewables Cool the Climate Apocalypse

By Energy Rant No Comments
My passion is applying the right technology in the right place and at the right time for maximum effectiveness. Not coincidently, that is precisely Michaels Energy’s purpose for existence: minimizing waste and maximizing value. Last week I wrote about the gargantuan resource requirement for solar and batteries to displace a single nuclear power plant, including 40,000 acres for the panels, which, in Iowa, is worth $600 million in farmland alone. This is a D- for minimizing waste and maximizing value. Offshore Wind This week, we’re turning our attention to wind generation. Renewable enthusiasts need to get behind offshore wind for…

Flowing Water at 22 Degrees Fahrenheit

Flowing Water at 22 Degrees Fahrenheit

By Energy Rant No Comments
As undergraduate mechanical engineering students, we took materials science courses and studied phase diagrams like the one below from “Metallurgy for Dummies.” Does that appear to be dummy-grade to you? It gave me a chuckle. A phase diagram for water (below) is decidedly simpler. The above diagram shows only liquid and solid phases of carbon steel, while the water diagram shows its three phases, solid (ice), liquid, and vapor (steam). The author writes, “Freezing Point: At a temperature of 0 °C and a pressure of 1.00 atm, this is the point at which water (liquid) freezes into ice (a solid).”…

Decarb Warriors

By Energy Rant No Comments
Last week I read a statement from a retail energy provider. It said, “100% green rates, always.” It doesn’t work that way. An aggregation of power sources, including renewable, nuclear, coal, and natural gas, are supplying the grid at any given time. The little electrons aren’t tagged by source and routed to any given customer(s). Second, even if that were impossible, er, I mean, possible, it’s shoving more hydrocarbon electricity onto someone else. In this way, it’s the same as the net zero con. Cheap but Unreliable Generating renewable power is easy and inexpensive, but as described in the net-zero…

Leveling the Skateboard Curve with a Demand Side Attack

By Energy Rant No Comments
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…
