Carbon dioxide capture results in lower productivity than advertised

by

In recent months, carbon dioxide (CO2It appears to be breeding all over the world. The announced quantities give hope that the technology can greatly help in the fight against ongoing climate change. But the researchers point out that the amounts actually removed from the atmosphere are lower.

[EN VIDÉO] With CarbonWorks, from CO2 capture to raw material production Phototrophic microalgae are like natural factories that capture carbon dioxide (CO2) and convert it into molecules that can be of interest to industry. French startup CarbonWorks has developed a photobioreactor that makes it possible to manufacture this process. Thus doubling the decarbonization of industry by capturing the CO2 it emits and then allowing it to replace the fossil raw materials it loves with biological raw materials produced from microalgae. © CarbonWorks

Carbon Dioxide Capture (CO2), we’ve been talking about it a lot for a few months now. Since the Intergovernmental Panel on Climate Change (IPCC) I declare that we are no longer in a position to dispense with this type of technology to reach our goal of zero emission By 2050. Initiatives are thriving everywhere. Launched by tech giants, TheFrontier InitiativeBut also announced at the beginning of the week by a few aviation giants, Airbus is in the lead.

subordinate searchingImperial University of London (UK) warns us today, though. Because they note that between advertising and the amount of carbon that is actually captured and stored, there is a good gap. From 19 to 30% depending on the situation. What gives a wrong picture of the contribution of these techniques to the struggle Global Warming.

Not everything is negative. Because according to researchers, between 1996 and 2020, there are still 197 million tons of carbon dioxide2 captured and stored. Very interesting number.

Fair numbers moving forward

Researchers report that by 2021, the global capacity to capture carbon dioxide2 Estimated at 40 million tons annually. For 26 operating facilities. However, there is no framework that requires these facilities to report how much carbon has actually been captured. Which, however, would help to understand to what extent exactly is captured and carbon dioxide storage2 Can help us fight Global Warming mankind.

Because the gap that exists between reality and data declared by different projects can mask a certain inefficiency in the techniques applied for CO2 capture2 or transportation systems used to transport it to storage locations. It can also refer to changes over time in the carbon dioxide source2 pick up.

Thus the researchers stress that more accurate figures – including the quantity recorded each year, the quantity transported each year and the quantity stored each year as well as the quality assurance measures taken at facilities – would make it possible to better model for large-scale dissemination. • Carbon capture and storage technologies. Monitor short-term reductions in greenhouse gas emissions and long-term resource needs for technology.
