Another step to taking back control

Technology will not save us, part 2

13 May 2019 — Felix Ple┼čoianu

This morning, a friend linked me to this article about a carbon sequestering technology being tested right now in Iceland. They can suck CO2 out of the air and capture it in layers of rock deep underground. Hooray! We're saved! We can stop and even reverse climate change!

Not so fast.

For one thing, I wouldn't use the word "forever" if I was them. Permafrost was also supposed to be, you know, permanent. Now it's melting so fast scientists can't keep up. Remember that scene in Ghostbusters where they turn off the ghost prison and all the malicious spirits go free at once? Imagine that at planetary scale.

Second, pay attention to the numbers. As they freely admit:

The CarbFix project reduces the plant's carbon dioxide emissions by a third, which amounts to 12,000 tonnes of CO2 captured and stored at a cost of about $25 a tonne.

By comparison, Iceland's volcanoes spew out between one and two million tonnes of carbon dioxide each year.

Wake me up when they can do something about the remaining 99.5% of emissions in their country alone. Or at least those of other facilities than the very powerplant generating the electricity needed for this energy-intensive process. Speaking of which.

The main drawback of the method is that it requires large volumes of desalinated water, which, while abundant in Iceland, is rare in many other parts of the planet.

Around 25 tonnes of water are needed for each tonne of carbon dioxide injected.

At least they're smart enough to use desalinated water rather than the precious natural freshwater they need to, you know, grow crops. And that stuff is becoming more valuable than gold in many parts of the world. But you know what the problem is with desalination? It's also energy-intensive. In other words, you need to build even more powerplants to sequester all the CO2 you wouldn't be generating if you just did nothing instead. Congrats, geniuses! And they know it, too.

You think that's just theory? Check out the end of the article:

Under the Paris climate agreement, Iceland has agreed to slash its greenhouse gas emissions by 40% by 2030.

Yet its emissions rose by 2.2% from 2016 to 2017, and have risen by 85% since 1990, according to a report by Iceland's Environment Agency.

Yep... just like in countries like the UK or Germany, where decades of massive investments in renewable energy just led to overall demand growing much faster than solar and wind can provide, meaning the difference has to be covered with... coal. In other words, even more CO2 emissions. Good job breaking it, hero.

Is it clear yet that new shiny toys aren't going to help us out of a hole we dug ourselves into by building far more technology than we needed in the first place, then wasting the vast majority of its potential? The only hope for human civilization is to downsize massively. And nobody's willing to even entertain the possibility: corporations because they'd have to give up their obscene profits, people because they've been conditioned to think they all somehow deserve to live like kings. Too bad you can't bribe, sue or intimidate mother nature.

We have 12 years to clean up our act. Tick tock, tick tock.
