Humanity is trying to make up for the damage it has done to the planet. Carbon capture is one of the most effective ways to combat climate change.. Naturally, the oceans and forests do this, and since 1996 society has wanted to do its part. However, although the volume is significant, the carbon captured and stored during these years is less than previously believed. Exactly between 19% and 30%.
This is the conclusion reached by a research group from Imperial College London, who published their theory in ‘Environmental Science and Technology Letters’.. As they explain, it lacks a common framework for measuring carbon sequestration rates, Estimated tonnes of CO2 held between 1996 and 2020 is overestimated and they “give a false picture of the technological contribution to the fight against climate change”.
And the carbon sequestration data we study is based on the capacity of 26 such facilities around the world, rather than calculating the actual carbon captured and stored in them.
this Carbon capture and storage (CAC or CCS in English: carbon capture and storage) is a technique used to remove carbon dioxide from the atmosphere or prevent it from reaching the atmosphere.
CCS consists of the decomposition of CO2 emitted by industry and energy production in combustion processes.and transport it to a geological storage area for long-term isolation from the atmosphere.
Mitigate climate change
“Carbon capture and storage (CCS) is one of the cornerstones of climate change mitigation.”, as highlighted by Yuting Zhang, the main author of this article. But as he insists, without establishing a homogeneous reporting method on this data, we miss out on an opportunity to “more proactively” address global warming.
The problem, according to the researchers, is A homogeneous and centralized regulatory framework has not been established that requires these facilities to report the actual rates of captured carbon.transported and stored.
Information for researchers vital to monitor the mitigation of climate change and to solve the problems that may affect the facilities in a timely manner.
“There is no international consensus on how much has been stored so far, apart from academic calculations,” says Samuel Krevor, co-author of the paper.we urgently need to create clear parameters to find out where we are.”
To conduct the study, the researchers observed the capture and storage rates of 20 of 26 CCS plants distributed worldwide from 1996 to 2020. Scientists consulted all kinds of sources to finally come to the following conclusion. 197 million tons of CO2 was stored.
Third party inspections required
When they compared their estimates with those reported, they noticed a gap between them. By reporting only the capacity of carbon capture facilities, 19% to 30% of sequestered carbon is overestimated.
“The approximately 200 million tons captured is significant, but these data cannot be dependent on scientific research,” says Krevor.
In this sense, Chris Jackson, another of the signatory researchers, states that this study also confirms that this is confirmed by Chris Jackson.capture capacity is not the best way to measure storage rates” and the need to “create a more tailored metric”.
To do this, reports should include key details such as projected capture rate capacity, maximum capture rate capacity, annual CO2 capture, transport and storage, downtimes of facilities, and related. third party audits to make all the information better quality.
