Did you know that the world’s carbon capture technology currently has the capacity to remove a mere 0.01% of global CO2 emissions? That’s right, folks – despite the hype surrounding carbon capture tech, we’re still woefully short of what’s needed to make a dent in the climate crisis. As of 2022, the global carbon capture market is projected to reach $8.2 billion, but experts warn that we need to be thinking on a much, much larger scale if we hope to avert catastrophic climate change.

So, what’s the holdup? The truth is, carbon capture technology has come a long way in recent years, but it’s still a nascent industry with a lot of room for improvement. There are several types of carbon capture tech, including post-combustion capture, which captures CO2 from power plant emissions; pre-combustion capture, which captures CO2 from natural gas processing; and direct air capture, which sucks CO2 straight out of the atmosphere.
One of the most promising developments in carbon capture tech is the emergence of direct air capture (DAC) startups like Climeworks and Carbon Engineering. These companies use a combination of chemical reactions and pressure swings to capture CO2 from the air, which can then be stored or used in products like concrete or biofuels. Sounds like science fiction, right? But DAC is already being used in real-world applications, including a large-scale project in Switzerland that can capture 1,000 tons of CO2 per year.

Another area of innovation is the use of biotechnology to enhance carbon capture. Researchers have discovered that certain bacteria can be engineered to produce enzymes that break down CO2 into useful chemicals, which can then be used to create everything from fuels to plastics. The potential for biotech-enhanced carbon capture is vast, but it’s still in the early days – and we need to see more investment in this area if we hope to make real progress.
Of course, there are also significant challenges to overcome before carbon capture tech can be scaled up to make a meaningful difference. One major hurdle is cost: current carbon capture technologies are often prohibitively expensive, especially when compared to traditional fossil fuel-based energy sources. Another challenge is the sheer scale of the problem – to put it bluntly, we need to capture tens of billions of tons of CO2 per year, not just a few thousand.
Despite these challenges, the good news is that the carbon capture industry is rapidly evolving, with new technologies and innovations emerging all the time. Governments, investors, and companies are starting to take the climate crisis seriously, and we’re seeing increased investment in carbon capture and storage (CCS) projects around the world. Whether we can scale up carbon capture tech in time to avoid catastrophic climate change remains to be seen – but one thing is clear: it’s time to get serious about this technology, and fast.
