"Icelandic Startup Seeks to Turn European Carbon into Rock"

Looking at the writer's very Icelandic name it just struck me that all the Icelandic folks built out of XX chromosomes, and thus often having "dottir" in their name, must look at the pronoun wars as pretty tame stuff.

By Ragnhildur Sigurdardottir (Bloomberg) —

European polluters will soon be able to ship their carbon emissions to Iceland to be turned into stone in the volcanic island’s bedrock.

Icelandic startup Carbfix is building a hub, called the Coda Terminal, which will receive carbon dioxide transported to Iceland in specially designed ships. There it will be turned into underground rock using a technique that imitates and accelerates the natural process of mineralizing carbon, providing a permanent storage solution.

Large-scale carbon capture and storage projects are on the rise in Europe with some reaching scale, including Porthos in the Netherlands, Norway’s Longship and Acorn in the U.K. The Coda Terminal differs in that its operations will be on land and that the injected CO? is turned into stone in less than two years. The company’s carbon-capture technology has already attracted interest from the likes of Bill Gates as they seek ways to limit global warming.

“The interest is high,” Carbfix Chief Executive Officer Edda Sif Pind Aradottir said in an interview. “More or less everybody wants to reduce their emissions.”

The service will be accessible for businesses in Northern Europe starting in 2025. Carbfix estimates the total investment will be 190 million to 220 million euros ($265 million), with projected annual revenue of 25 million to 45 million euros when at full capacity. Carbfix will tap outside investors to fund the construction.

“It’s crystal clear that without large scale carbon capture and storage we will not be able to meet the goals of the Paris agreement,” Aradottir said. “It’s important that we bring different solutions in this sector to scale as quickly as possible.”

The key advantage of mineral storage is that it relies on a network of shallow injection wells, rather than a single deep high-capacity well. This allows for a modular expansion where wells can be added to the network step by step. No monitoring is needed once the CO? has been turned into stone.

Low-Cost Solution

“The storage part will be cheap,” Aradottir said, costing less than 20 euros per metric ton. That’s “much lower than for other projects which are operated offshore.”

The Coda Terminal isn’t the first proposal for a country to accept others’ emissions to be buried in their own backyard. Norway’s Longship project is expected to take on emissions from other countries via ships, though the CO? will be injected under the sea rather than on land. The first leg of the project received Norwegian government funding last year.

The relatively low cost of storage for Carbfix means the process is expected to remain cost-effective even when long-distance shipping to Iceland is factored in, according to Aradottir....


Possibly also of interest, last week's "We’ve got carbon capture all wrong":

I don't know if I would use the word wrong but that quibble aside this article, especially deeper into it, presents some very interesting opportunities to complement current approaches.

Just as a personal preference, sequestering CO2 as a mineralized solid seems like a possibly more fruitful path than either tying carbon up in plant material—because the plant dies, the carbon gets released, reforms into CO2, that whole carbon cycle thing—or as a gas buried deep under the earth's crust—the potential disaster scenario of a catastrophic leak.

But maybe that's just me....
