Dutch breakthrough in affordable and rapid capture of CO2 from the air
By: Teun Schröder

The Dutch Carbyon says it has achieved a breakthrough in the affordable removal of CO2 from the air. Direct Air Capture (DAC) is seen as a necessary but costly technology to remove carbon from the atmosphere and thus reduce the greenhouse effect.
One of the major challenges of DAC technologies is that the process of capturing CO2 from the air is extremely slow. The most commonly used materials need hours to bind CO2. Carbyon developed a new type of material that can shorten this process to a few minutes. One kilo of Carbyon material can capture 5 tons of CO2 over a year.
With a CAPEX of 50 dollars per tonne of CO2, Carbyon is in any case well on its way to keeping the total costs of DAC within limits. More than a year ago, Change Inc. spoke. already with Hans de Neve, founder of Carbyon. He said about Carbyon's objectives at the time: “Currently it costs 500 to 700 euros to capture one ton of CO2. That would have to be 50 to 100 per tonne to be able to apply it on a large scale.”

Less energy required
The cost of capturing CO2 is largely related to the amount of energy the process requires. Initially, Carbyon's technology suffered from damage due to water absorption, which resulted in a higher energy demand for the process. But the recent breakthrough has resulted in much less water absorption, limiting energy demand to 2,500 kilowatt hours per tonne of CO2. In the earlier interview, De Neve indicated that the price 'must be closer to 1,000 kilowatt hours per tonne to make the business case interesting.'

Lots of renewable energy
DAC technology can in principle be applied anywhere in the world. But the business case becomes more interesting in places where renewable energy can be generated easily and cheaply, for example with many solar and wind farms, such as Australia, Tasmania and southern Chile.

$100 per ton of CO2
“Our tireless confrontation with Mother Nature's laws of nature has finally given us insight into how we can solve this puzzle,” De Neve now says in a press release. “This is a major team effort; 2,500 kilowatt hours per ton is a challenging milestone for any DAC technology. By demonstrating this with a fully electric, low-CAPEX technology, Carbyon is in pole position to reach the target of 100 dollars (90 euros, ed.) per tonne that the market is looking for. Nothing can stop us now.”

    The Dutch are really walking the talk towards sustainability. Good job.

      We should embrace such initiatives that are crucial for a sustainable future and a cleaner environment.

        The Dutch engineering to capture carbon while being affordable is welcome as other methods have been fronted to do the same but have been pretty costly
