You’d think that after decades of warnings from scientists and environmentalists, the world would be doing everything in its power to reduce carbon emissions. But the reality is sobering: a recent report by the International Energy Agency (IEA) found that greenhouse gas emissions actually increased by 1.4% in 2022, marking a record high. The most shocking part? This surge in emissions was largely driven by a rebound in fossil fuel use, particularly in Asia, where coal and gas-fired power plants were brought back online to meet growing energy demand.

The numbers are stark: we’re still releasing an astonishing 42 billion metric tons of CO2 into the atmosphere every year, with no clear end in sight. And yet, amidst this bleak backdrop, there’s a growing sense of optimism. Carbon capture technology (CCT) – a suite of innovations designed to suck CO2 out of the air and store it underground or utilize it in industrial processes – is gaining traction faster than ever.
At the forefront of this revolution are startups like Climeworks, which has developed a modular carbon capture unit that can be deployed at scale. Using a proprietary technology that captures CO2 from the air, Climeworks’ machines can be integrated into power plants, industrial facilities, and even homes, to name a few applications. The company claims its tech can remove up to 1,000 tons of CO2 per year – a significant dent in the 42 billion-ton problem.

Another key player in the CCT space is Global Thermostat, a US-based firm that’s developed a carbon capture system using a proprietary mineral-based technology. Their patented process can capture CO2 from the air at a cost of just $30 per ton, a significant reduction from the industry average of $100 per ton.
But carbon capture isn’t just about tech; it’s also about policy and economics. Governments around the world are starting to recognize the value of CCT, with some countries offering lucrative incentives for companies that invest in carbon capture infrastructure. In the US, for example, the Inflation Reduction Act includes tax credits for projects that deploy CCT, which could unlock billions of dollars in investment.
Of course, CCT has its limitations. For one, it’s still an expensive technology, which means that it’s only feasible for large-scale industrial applications… for now. Additionally, there are concerns about the long-term storage of CO2, and the potential risks of leakage or even earthquakes caused by injection into the ground.
Despite these challenges, the trajectory of carbon capture technology is clear: it’s on the rise. With the likes of Climeworks, Global Thermostat, and other innovators pushing the boundaries of what’s possible, we’re already seeing a significant reduction in emissions from some of the world’s biggest polluters. Can tech save us from ourselves? It’s a tall order, but it’s clear that carbon capture tech is at least a crucial part of the solution.
