It’s estimated that the world’s carbon capture technology has the potential to remove up to 10 gigatons of CO2 from the atmosphere by 2050, but currently, we’re only capturing a paltry 40 million tons. That’s a whopping 99.6% of our potential being left on the table. The question is, what’s holding us back?

The science is clear: we need to drastically reduce our greenhouse gas emissions to avoid the worst effects of climate change. But despite the urgency of the situation, many experts agree that carbon capture technology (CCT) is one of the most promising solutions to date. So, what exactly is carbon capture tech, and how can it help us save the planet?
Carbon capture technology refers to any process that captures CO2 emissions from sources like power plants, industrial processes, and even directly from the air. There are several types of CCT, including post-combustion capture, which captures CO2 after it’s been emitted; pre-combustion capture, which captures CO2 before it’s burned; and direct air capture, which captures CO2 from the air itself.

One of the most promising types of CCT is chemical looping combustion, which uses a metal oxide to capture CO2 as it’s emitted. This process has already been proven to be effective in reducing emissions from power plants, and it’s also been shown to be cost-competitive with traditional carbon capture methods.
But carbon capture tech isn’t just about reducing emissions from existing sources. It’s also being used to create new, low-carbon industries. For example, companies like Climeworks are using direct air capture to produce carbon-neutral fuels and chemicals. These fuels and chemicals can then be used to power everything from cars to buildings, reducing our reliance on fossil fuels and lowering our carbon footprint.
Of course, there are still significant challenges to overcome before carbon capture tech can reach its full potential. One of the biggest hurdles is cost: while the cost of CCT is decreasing, it’s still much higher than traditional carbon reduction methods. Another challenge is scalability: as demand for carbon capture tech grows, we’ll need to find ways to produce it at scale without sacrificing efficiency or effectiveness.
Despite these challenges, many experts are optimistic about the future of carbon capture tech. “We’re on the cusp of a revolution in carbon capture,” says Dr. Jennifer Holmgren, CEO of LanzaTech. “The technology is getting better, the costs are coming down, and the industry is starting to come together. I think we’re going to see some really exciting developments in the next few years.”
As the world continues to grapple with the challenges of climate change, carbon capture tech is emerging as a vital solution. It’s not a silver bullet, but it’s an important tool in our toolkit. And with continued innovation and investment, it could just be the key to unlocking a sustainable future for our planet.
