CarbFix2 in the Horizon Magazine


Storing CO2 underground can curb carbon emissions, but is it safe? is an article by Jonathan O'Callaghan that was published by the Horizon Magazine. In this article the projects on CCS are addressed. Click here for the full article.

Below is a short overview from the article:

Some of the biggest issues facing the CCS industry is the distrust of the public, the concern of CO2 leakage from CCS and scalability of CCS.


These factors are some of the factors the ENOS (Enabling Onshore CO2 Storage) are investigating. ENOS are conducting research at five different locations with the goal in mind to:

"...enhance the development of CO2 storage onshore, close to CO2 emission points. Several field pilots in various geological settings will be studied in detail and best practices that stakeholders can rely on will be produced. In this way, ENOS will help demonstrate that CO2 storage is safe and environmentally sound and increase the confidence of stakeholders and the public in CCS as a viable mitigation option"

In their research they are monitoring the leakage, safe storage and seismic activity, as well as building detection tools to select safe sites. At the same time, they are addressing public concerns by holding meetings with local communities to explain to them how the technology works.


CarbFix2 is taking a totally different approach. By dissolving the CO2 in water and injecting the mixture into basaltic rocks there is no need to worry about leakage. The basaltic rock reacts with the Carbon in CO2 to form the mineral Calcite. What is impressive is that CarbFix2 has demonstrated an entire CCS cycle at only €22 per metric tonne CO2 which is a lot less than previous cost assessments in CCS at €35-90 per metric tonne CO2. There are also no issues scaling up to 100%.

"We have more than enough capacity theoretically to store permanently all the CO2 coming from burning [fossil fuels]"


The technology is there, ENOS and CarbFix2 are proving that CCS is both safe and viable. Now all that is missing is the political will to invest in CCS.
