A staggering 40% of global carbon emissions could be captured and stored by 2050, according to a recent report by the International Energy Agency (IEA). Yes, you read that right – 40%! This massive potential has left many in the climate community abuzz with excitement, and for good reason. Carbon capture technology (CCT) has made tremendous strides in recent years, and its impact could be nothing short of revolutionary.

For those new to the concept, carbon capture technology refers to any process that captures CO2 emissions from industrial sources, such as power plants and factories, and stores them underground or utilizes them in products like concrete. The idea is simple: prevent carbon dioxide from entering the atmosphere, where it contributes to climate change.
The most common type of CCT is post-combustion capture, which involves capturing CO2 from power plant exhaust. This is the same technology that’s been used at various commercial scale plants around the world, including the Petra Nova plant in Texas, which captures over 1.6 million tons of CO2 emissions annually. However, there are many other types of carbon capture technologies being developed, each with its unique advantages and challenges.

One of the most promising areas of research is direct air capture (DAC). DAC involves capturing CO2 directly from the air, rather than from industrial sources. This technology has the potential to be much more widespread, as it can be used in urban areas and even in homes. Companies like Climeworks and Carbon Engineering are already commercializing DAC technologies, and their units are being used to capture CO2 for various applications, including carbonated beverages and even rocket fuel!
Of course, no discussion of carbon capture technology would be complete without mentioning the all-important question of cost. Currently, carbon capture is still a relatively expensive process, which has limited its widespread adoption. However, many experts believe that costs will come down significantly as the technology continues to scale up. In fact, some estimates suggest that the cost of carbon capture could drop by as much as 50% over the next decade, making it a more viable option for industries and governments.
So, what does the future hold for carbon capture technology? As the world continues to grapple with the climate crisis, CCT is poised to play a crucial role. With governments and companies investing heavily in the sector, it’s likely that we’ll see significant advancements in the coming years. Whether through direct air capture, post-combustion capture, or other innovative technologies, carbon capture technology has the potential to be a game-changer in the fight against climate change. And with a 40% capture rate on the horizon, it’s clear that this technology is one to watch.
