Iceland is famous for its stunning natural landscapes, including majestic waterfalls, black sand beaches, and shimmering glaciers. However, it is also at the forefront of innovative climate change solutions. In southwestern Iceland, there are large facilities dedicated to capturing carbon dioxide (CO2) from the atmosphere and storing it underground for thousands of years.
While it may sound like something out of a science fiction novel, this technology is very real. Our planet is experiencing rapid warming, with CO2 levels now surpassing 415 parts per million, the highest in 800,000 years. Although there is debate about what level of CO2 is dangerous, it is clear that reducing these levels is crucial to prevent severe climate change. According to the Intergovernmental Panel on Climate Change (IPCC), we need to remove between 100 and 1,000 gigatons of CO2 from the atmosphere by the end of the century. To put this in perspective, this is equivalent to 20 years of global greenhouse gas emissions.
So, how can we achieve this massive reduction? Alongside the rapid adoption of renewable energy and large-scale reforestation, the IPCC highlights the importance of carbon dioxide removal technologies. This is where direct air capture (DAC) technology becomes essential. Although the idea of extracting CO2 directly from the air has been around for over a decade, it has gained significant attention recently.
DAC technology captures CO2 from the atmosphere and stores it in a stable form, such as underground rock formations. Climeworks, a company leading this effort, has been using this technology in Iceland since late 2017. The process involves a collector that captures CO2 from the air using reusable filters. As air enters the plant, CO2 molecules attach to the filter materials. The filter is then heated to about 100°C, causing the CO2 to detach and collect as a concentrated gas. This gas is mixed with water and injected underground, where it reacts with basalt to form stone within two years. The CO2-free air is then released back into the atmosphere, and the cycle continues.
Beyond capturing and storing CO2, Climeworks is exploring other uses for captured carbon. For instance, they are transforming it into methane to power vehicles at their plant in Italy. In Switzerland, a waste incineration site provides energy for their DAC plant, which uses captured carbon to help ripen vegetables in nearby greenhouses. By demonstrating various applications of captured carbon, Climeworks has become the first DAC company to operate commercially. They claim their technology offers a negative emissions solution, meaning more carbon is removed from the atmosphere than emitted.
Despite its promise, there are questions about the effectiveness of this technology. It is clear that it needs to be significantly scaled up to impact the 1,000 gigatons of CO2 that must be removed. While the Climeworks plant in Switzerland can capture 900 metric tons of CO2 annually, a major concern is the substantial energy required to extract CO2 from the air. Estimates suggest that scaling up the process will consume about 2,000 kWh of heat and 650 kWh of electricity per metric ton of CO2. The Iceland operation aims to reduce its carbon footprint by sequestering carbon on-site and utilizing renewable energy from nearby geothermal plants.
Climeworks has set a goal to eliminate about 400 million metric tons of CO2—or roughly 1% of global emissions—by 2025. They plan to rely on the increasing value of carbon as a trading commodity to help buyers, such as energy companies and countries, meet climate targets. However, achieving just a 1% reduction highlights that while technologies like Climeworks’ solutions are promising, they cannot address climate change in isolation. The search for additional solutions continues.

**Iceland: The Land of Majestic Waterfalls and Innovative Climate Solutions**
Iceland is known for its breathtaking waterfalls, black sands, and sparkling glaciers. But it’s also home to one of the world’s most intriguing solutions for addressing climate change. Nestled in southwestern Iceland are large facilities capable of capturing CO2 from the atmosphere and safely storing it underground for millennia.
This may sound like science fiction, but it’s a reality. Our planet is warming rapidly, with CO2 levels now exceeding 415 parts per million, the highest they’ve been in the past 800,000 years. While there is debate over what constitutes a dangerous threshold, there is agreement that these levels must decrease to prevent catastrophic warming. The Intergovernmental Panel on Climate Change (IPCC) estimates that by the end of the century, we need to remove at least 100 gigatons, and potentially up to 1,000 gigatons, of CO2 from the atmosphere. To put this in perspective, that’s equivalent to 20 years’ worth of global greenhouse gas emissions.
You might be wondering: how can we achieve this? In addition to rapidly adopting renewable energy and large-scale reforestation, the IPCC emphasizes that carbon dioxide removal technologies will be essential in combating climate change. This is where direct air capture (DAC) technology comes into play. The concept of extracting CO2 directly from the air has been around for over a decade, but it has gained significant traction in recent years.
DAC technology works by capturing carbon dioxide from the atmosphere and storing it in a more benign form, such as underground rock formations. Climeworks has been implementing this technology at its plant in Iceland since late 2017. The process involves a collector that captures CO2 from the air using reusable filters. As air is drawn into the plant, CO2 molecules bind to the filter materials. The filter is then heated to about 100°C, causing the CO2 to detach and collect as concentrated gas. This gas is mixed with water and injected underground, where it reacts with basalt to form stone in under two years. The CO2-free air is then released back into the atmosphere, and the cycle continues.

They claim their technology represents a negative emissions solution, meaning more carbon is being removed from the atmosphere than is being emitted.
However, there are questions about the effectiveness of this technology. It is evident that it needs to be significantly scaled up to make a meaningful impact on the 1,000 gigatons of CO2 that must be removed. While the Climeworks plant in Switzerland can capture 900 metric tons of CO2 annually, a major concern is the substantial energy required to extract CO2 from the air.
