The biggest, and widely mentioned, a problem associated with climate change is the emission of carbon dioxide into the atmosphere. So the US wants to mobilize and remove billions of tons of CO2 from the air every year.
The idea came about, as reducing emissions alone will no longer be an effective solution.
Reducing global carbon dioxide emissions can help to reduce the already notorious impact of climate change. However, the United States of America (USA) believes that this isolated act, even if carried out by all countries in the world, will no longer be enough.
So, in an attempt to reverse troubling scientific predictions, the US Department of Energy (DOE) announced ambitious plans to accelerate the development of carbon-scavenging technology. With the name “Carbon Negative Shot”, the initiative aims to expand carbon dioxide removal technologies and make them profitable, reducing their price to less than 100 dollars per ton.
In this way, billions of tons of CO2 could be removed from the atmosphere without too high a cost associated with the process. According to the US DOE, removing one billion tons, or one gigaton would be the equivalent of eliminating the pollution produced by 250 million vehicles in a year.
For the initiative to be a success, DOE will have to manage the amount of energy needed to extract the amount of CO2 it promises. After all, if not carefully planned, technologies to remove carbon dioxide from the atmosphere could contribute to the problem they are trying to solve.
The world is committed to removing CO2 from the atmosphere
In order to achieve the ambitious goal, the US DOE will have to significantly improve the technology of the existing carbon dioxide removal facilities, as well as propose others.
Right now, the world’s largest direct CO2 capture facility is in operation in Iceland and goes by the name of Orca. It is currently capable of extracting 4,000 tons of carbon dioxide, placing itself far short of the American dream.
In addition to this, there is another hosted by Scotland. Built-in collaboration with British energy transition company Storegga Geotechnologies and Canadian carbon dioxide capture technology company Carbon Engineering, it will ultimately remove up to one million tonnes of CO2 a year, according to the two companies.
According to the notices that are being issued by specialists, the aforementioned zero emissions will not materialize if the measures are only related to their reduction. As the Union of Concerned Scientists (UCS) noted: “We need to actively remove carbon dioxide from the atmosphere or compensate for its effects.”
