Did you know that by the end of 2022, the world’s carbon capture capacity will be a staggering 0.06% of global CO2 emissions? That’s right, a meager 0.06%. To put that into perspective, it’s like trying to put a Band-Aid on a bullet wound. While carbon capture technology has made significant strides in recent years, it’s clear that we’re still woefully behind in our efforts to mitigate climate change.

But what exactly is carbon capture technology, and how does it work? Simply put, it’s the process of capturing and storing the carbon dioxide emitted by power plants, industrial processes, and other sources before it enters the atmosphere. This can be done through various methods, including chemical solvents, membrane technology, and even direct air capture.
One of the most promising areas of carbon capture tech is the use of industrial-scale carbon mineralization. This process involves injecting CO2 into rock formations, where it can be stored for thousands of years. Companies like Carbon Engineering and Climeworks are already pioneering this technology, with some projects boasting capture rates of up to 90%.

Another area of innovation is the development of more efficient and cost-effective carbon capture systems. For example, a startup called 8 Rivers is working on a technology that can capture CO2 from power plant flue gas at a cost of just $30 per ton. That’s a fraction of the cost of traditional carbon capture methods, which can range from $50 to $100 per ton.
But despite these advances, there are still significant challenges to overcome. For one, carbon capture technology is still relatively expensive, making it difficult for companies to justify the investment. Additionally, there are concerns about the long-term safety and efficacy of storing CO2 underground.
So, what does the future hold for carbon capture tech? While it’s unlikely that we’ll see a dramatic increase in global capacity anytime soon, there are still reasons to be optimistic. Governments and corporations are increasingly recognizing the importance of carbon capture, and investment in the sector is on the rise.
In fact, the International Energy Agency (IEA) estimates that by 2050, carbon capture and storage could account for up to 20% of the world’s emissions reduction. That’s a staggering number, and one that underscores the critical role that carbon capture technology can play in our efforts to combat climate change.
Of course, there’s no single silver bullet solution to the climate crisis. But what’s becoming increasingly clear is that carbon capture technology, when used in conjunction with other mitigation strategies like renewable energy and energy efficiency, can be a powerful tool in our fight against climate change. It’s a start, at least – and one that’s worth exploring further.
