Dive Into Cement Manufacturing Emissions

By Jeff Ihnen Energy Rant No Comments

Over the years, I’ve seen numerous mentions of decarbonizing concrete or cement. Random articles describing the need and means to decarbonize cement include this McKinsey article, this DOE post, and this Canary Media article. Those don’t cut it for me. I set out to explore cement making and why it is so carbon-intensive. But first, some terminology review is advised to differentiate cement from concrete. Growing up, in college, and even post-college, we used the term cement synonymously with concrete. E.g., “cement hands” to describe a guy who couldn’t catch a basketball or football or “cement head” to tell civil engineers. Each of…

Electric Vehicle Plans With the End in Mind

By Jeff Ihnen Energy Rant No Comments

This week I’m repackaging recent news on electric vehicle (EV) developments – market, technical, and utility impacts. I like to look at scale (macro) rather than ubiquitous siloed micro thinking. Is it realistic to scale rare earth mineral mining, battery manufacturing, and battery disposal? What about charging logistics, third-world labor, and grid impacts? Breaking the Grid? Let’s start with the revelation that force, in the form of mandates, will break things. An aeronautical engineer’s piece in Energy Central, says EVs, at scale, will break the grid. He notes that the Biden regime is developing restrictions requiring the market share of…

Are You Serious About the Climate Apocalypse?

By Jeff Ihnen Energy Rant, Featured Energy Rant No Comments

Washington Post headline last week: “World is on brink of catastrophic warming, U.N. climate change report says.” Wolf! Wolf! People aren’t serious about decarb, and this post will prove it, but I provide ways to get it done. Is Solar Plus Storage Competitive? Solar is nice, but the numbers are ugly. If solar and storage with batteries were a serious contender for a clean energy grid, electric utilities would be soiling themselves because solar and batteries would put them out of business as customers would install their own and cut the cord. Let’s look at some basic arithmetic. Lazard pegs…

1,500 Pages of Deregulation

By Jeff Ihnen Energy Rant No Comments

Last week I mentioned genuine intelligence over artificial happy-talk intelligence. Want to know what the latter looks like? See this Forbes article in which data solves all problems, including heating and cooling buildings. “There is an opportunity to build the foundations of a long-term digital strategy for buildings in all industries, to achieve decarbonization goals, reduce energy use and running costs, and boost resiliency and competitiveness.” How many Btus of energy are in a terabyte anyway? Harnessing data, plus actionable analytics, which is rare, can help shave 10% or even 20% off energy costs. Still, it must be integrated with…

Decarb Warriors

By Jeff Ihnen 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…

COP27, Elites, and Engineers

By Jeff Ihnen 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…

Developing Nations are Going Nuclear – Will the West Follow or Fall Futher Behind?

By Jeff Ihnen Energy Rant No Comments

Last week I provided an extensive analysis of how Chernobyl’s RBMK reactor design and the chain of reckless events led to its 1986 disaster. The study sets the stage to explain why that won’t happen with power plants in the United States. Let’s take a minute to examine why nuclear power is a good fit for our needs. Nuclear Power’s Plug into Our Grid Commercial nuclear power plants operate continuously at full power for 90-95% of the year. They require an average of three to four weeks a year for maintenance and refueling. One charge of nuclear fuel, about 3%…

Decarbonization Strategies for Manufacturing

By Jeff Ihnen Energy Rant No Comments

Last week a Yahoo News reporter headlined an article, Biden Administration Seeks to Lower Industrial Greenhouse Gas Emissions-and-That-Won't Be Easy. My first reaction: It won’t be easy to decarbonize any sector: residential, commercial, industrial, and transportation, although I did see that, like wind energy, the passenger blimp is making a comeback (say whaaat?). Will it replace passenger jets? I don’t think so. I focus on the above-linked article and industrial electrification and decarbonization in this post. The Yahoo author references the chart below for shares of GHG emissions. I assume that emissions from electricity generation are not double counted into…

Profiles in Decarb – I Call Ham

By Jeff Ihnen Energy Rant No Comments

When I started at Michaels millennia ago, we had a brilliant walking encyclopedia of knowledge and engineering know-how. His name was Dave Hamilton, or Ham for short. He was probably 30 years older than me. My boss at the time said Ham knew the answer to any problem. Younger engineers would spend a few weeks to prove he was right. Scaling Electrification A couple of weeks ago, in the final of a series on electrification prompted by the EPRI conference in Charlotte, I wrote in Electrification at Scale that decarb fans need to 1) brace for consequences such as 9,000…

Electrification at Scale

By Jeff Ihnen Energy Rant No Comments

Two weeks ago, I wrote the “electric storage industry that is grabbing all they can before someone figures out that will never be the answer to bridging gaps of intermittent renewables.” Time’s up. Utility Dive last week quoted a North American Electric Reliability Corporation (NERC) spokesman: “Batteries aren’t going to do it, and we’re going to need a backup fuel for wind and solar. So this is important to invest in.” The rest of this post includes a dive into consumer choice and what things might look like at scale. Consumer News In fresh news from Holman Jenkins of The…
