Orca, Climeworks & The Philosopher’s Stone

We started noticing Climeworks three years ago and have posted about Orca a couple times since then. But the video above is worth the longer look, and our thanks to Yale Climate Connections for pointing to it in their story Iceland facility sucks carbon dioxide from air, turns it into rock:

The technology will need a lot of scaling up to make a difference to the climate.

In Iceland, a new facility called Orca is pulling carbon dioxide out of the air so it can be stored underground. Continue reading →

Global North, Global South & Responsibilities

David Wallace-Wells has done it again. Devastated me with considerations I should have had on my own, but had not. And he makes it so vivid that once you see his point you cannot stop seeing it. Having lived in the Global South for a majority of my adult years, but having been born into and lived in the Global North for the first half of my life, this story resonates with me in ways I cannot quite describe. But the quote from Proverbs in yesterday’s post seems even more intensely relevant:

Climate Reparations

A trillion tons of carbon hangs in the air, put there by the world’s rich, an existential threat to its poor. Can we remove it?

The math is as simple as the moral claim. We know how much carbon has been emitted and by which countries, which means we know who is most responsible and who will suffer most and that they are not the same. We know that the burden imposed on the world’s poorest by its richest is gruesome, that it is growing, and that it represents a climate apartheid demanding reparation — or should know it. We know we can remove some of that carbon from the atmosphere and undo at least some of the damage. We know the cost of doing so using tools we have today. And we know that unless we use them, the problem will never go away. Continue reading →

Orca On

The video above is the shortest, clearest primer we could find to explain how this machine technology works. With Orca now on we will get the chance to see how much promise this process holds for carbon capture’s machine approach versus the tree approach, which we now know needs some reconsideration:

World’s biggest machine capturing carbon from air turned on in Iceland

Operators say the Orca plant can suck 4,000 tonnes of CO2 out of the air every year and inject it deep into the ground to be mineralised

The world’s largest plant designed to suck carbon dioxide out of the air and turn it into rock has started running, the companies behind the project said on Wednesday.

The plant, named Orca after the Icelandic word “orka” meaning “energy”, consists of four units, each made up of two metal boxes that look like shipping containers.

Constructed by Switzerland’s Climeworks and Iceland’s Carbfix, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide out of the air every year, according to the companies. Continue reading →

Carbon Capture Closer

Our thanks as always to Jon Gertner for this news.  Combining capturing carbon with other goals is not new, but it has been goal-setting elusive of significantly robust results; we are getting closer:

The Dream of Carbon Air Capture Edges Toward Reality

Next month, an industrial facility in Iceland will join a growing number of projects to remove CO2 from the air and put it underground. But major hurdles, including high costs, remain before this technology can be widely deployed and play a key role in tackling climate change.

In early September, at an industrial facility located about 25 miles southeast of Reykjavik, Iceland, the Swiss company Climeworks will mark the opening of a new project named “Orca.” At least in a conventional sense, Orca doesn’t actually make anything. It is comprised of eight elongated boxes that resemble wood-clad tanks. Each of these boxes — known as “collectors” — is roughly the size of a tractor trailer, and each is festooned with 12 whirring fans that draw a stream of air inside. Within the collectors, a chemical agent known as a sorbent will capture CO2 contained in the air wafting through. Continue reading →
