Decarbonizing District Steam and Chilled Water Plants

By Energy Rant No Comments
Let's begin with Oxford Dictionary's definition of decarbonization. Noun: reduction or elimination of carbon dioxide emissions from a process such as manufacturing or the production of energy. Last week, I introduced central or district plants that serve multiple buildings with steam, chilled water, and, in many cases, electricity. District plants serve colleges, healthcare, manufacturing campuses, and, in some cases, entire sections of cities. This week, I describe issues and strategies to save energy and decarbonize these plants. As I learned early in my energy efficiency career, it is essential to understand the design logic behind the system before recommending modifications. Steam moves…

Decarbonization – An Introduction to District Plants

By Energy Rant No Comments
I would like to see a poll of peoples’ suggestions for decarbonization. My guess is solar panels would be near the top; next, maybe an electric vehicle; after that, maybe electrified appliances and HVAC. Are any of these investments cost-effective? Keeping it simple, are the accrued savings over the life of the project or object more than the cost? It depends on the baseline alternative and various stackable incentives. Without guessing and getting into details, I believe consumer electrification and decarbonization are driven more by non-financial matters. What about commercial and industrial facilities? It gets decidedly more challenging because the…

The Non-Energy Benefits of COVID, and Energy

By Energy Rant No Comments
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. As a result, my Feng and Shui have been in balance. Third, my car insurance company has credited my account a few times because they think I’m driving less – which reminds me of the fourth: gasoline prices are lower than ever, inflation-adjusted. Fifth, I’ve…

No Free Lunch

By Energy Efficiency, Energy Rant No Comments
A few years ago, I took my beloved Acura to the tire store for new tires.  As I was sitting on their crappy molded plastic chairs at a Formica table working away on my laptop, a cheesy 20-something sales guy approached me and asked if I would like a free alignment.  “I don’t have a problem.”  “But it’s free.  No obligation”, he goes on.  “Ah what heck, go ahead.”  He returned a few minutes later as I’m hammering away on my laptop and he says my wheels should be aligned because…whatever.  I put on a scrunchy-face look and decide that…
