Climeworks is a groundbreaking Swiss company at the forefront of carbon dioxide removal technology, renowned for its innovative approach in tackling the urgent global challenge of climate change. Established in 2009 by Jan Wurzbacher and Christoph Gebald, Climeworks has made significant strides in developing and implementing direct air capture (DAC) technology to remove carbon dioxide (CO2) from the atmosphere. The company’s name, Climeworks, aptly reflects its mission to harness the Earth’s natural processes and human ingenuity to combat climate change by literally “working on the climate.”
Through its pioneering DAC technology, Climeworks has garnered widespread recognition and has become a leader in the field of carbon dioxide removal. The company’s cutting-edge approach involves capturing carbon dioxide directly from the ambient air, employing specialized filters and chemical processes to trap the greenhouse gas effectively. Once the CO2 is captured, Climeworks offers several pathways for its utilization, thereby contributing to the circular economy and creating sustainable solutions for carbon emissions.
Climeworks’ DAC technology operates on a cyclical system that includes two main stages: adsorption and desorption. In the adsorption phase, air is drawn into the system, and the CO2 molecules selectively bind to the surface of adsorbent material within the filters. The adsorbent material is specifically designed by Climeworks to capture CO2 effectively and efficiently, even at low atmospheric concentrations. As the air passes through the filters, other trace gases are allowed to pass through, ensuring a clean and purified capture of carbon dioxide.
The second stage, desorption, involves releasing the trapped CO2 from the adsorbent material for subsequent processing or storage. Climeworks has ingeniously developed a thermal swing adsorption process for desorption. By using low-grade waste heat as an energy source, the bound CO2 is released from the filters, making the entire DAC system energetically sustainable. This energy-efficient approach distinguishes Climeworks from traditional carbon capture methods, which often rely on large amounts of external energy, sometimes derived from fossil fuels, leading to a counterproductive carbon footprint.
Climeworks’ DAC plants are modular and scalable, allowing for flexibility in deployment across diverse geographical locations. The company envisions a distributed network of these plants strategically placed worldwide to maximize efficiency and address regional carbon capture needs. This decentralized approach also ensures that DAC technology can be integrated with other industries, such as greenhouses or beverage producers, to use the captured CO2 in their processes, further promoting a circular economy.
One of the significant achievements of Climeworks is its partnership with Carbfix, an Icelandic company, to pioneer a carbon storage solution using captured CO2. In this collaboration, Climeworks provides the DAC technology to capture CO2 from the air, and Carbfix injects the CO2 into basaltic rock formations, where it undergoes mineralization, turning into stable carbonate minerals in a remarkably short time frame. This process not only prevents the CO2 from re-entering the atmosphere but also ensures permanent storage, effectively reversing the carbon emissions and contributing to carbon neutrality or even carbon negativity.
Climeworks’ commitment to sustainability extends beyond technology development. The company operates its DAC plants using renewable energy sources, such as solar or wind power, to minimize its operational carbon footprint. Moreover, Climeworks continuously strives to optimize its technology and reduce costs to make DAC more economically viable and accessible to governments, businesses, and individuals alike. This dedication to innovation and efficiency has earned Climeworks several awards and accolades, solidifying its reputation as a pioneering force in the fight against climate change.

As a result, Climeworks has been involved in numerous collaborative projects with public and private entities, contributing its expertise and technology to accelerate climate action. Such collaborations have the potential to foster a more sustainable and climate-resilient future by combining the strengths of multiple stakeholders in the fight against climate change.
Climeworks’ vision goes beyond merely capturing and storing carbon dioxide; the company aims to create a closed-loop solution, where the captured CO2 is utilized for various applications, driving a circular economy. One promising avenue is the utilization of the captured CO2 in the production of synthetic fuels, also known as e-fuels. These e-fuels can play a crucial role in decarbonizing transportation and industrial sectors, effectively reducing greenhouse gas emissions in areas where direct electrification is challenging or unfeasible. Climeworks’ DAC technology can thus contribute to a more comprehensive and integrated approach to addressing climate change, fostering a carbon-neutral society.
Apart from e-fuels, the captured CO2 holds potential for applications in other sectors. For instance, it can be used to enhance agricultural productivity by injecting it into greenhouses to enrich plant growth. This practice, known as CO2 fertilization, not only boosts crop yields but also helps to maintain food security in the face of a changing climate. Additionally, Climeworks’ DAC technology opens doors to innovative solutions in carbon dioxide utilization, such as carbonation for the beverage industry, carbon mineralization for building materials, and even carbon-negative materials, further contributing to a circular economy and sustainable development.
To achieve widespread adoption and impact, Climeworks acknowledges the importance of continued research and development.
