What is Climeworks?
Climeworks is a Swiss-based company that specializes in direct air capture (DAC) technology. Founded in 2009 by engineers Christoph Gerald and Jan Wurzbacher, Climeworks aims to capture CO2 directly from the atmosphere, thus reducing greenhouse gas emissions and combating climate change. As a leader among carbon removal companies, Climeworks' mission is to provide scalable carbon removal solutions through their innovative air capture technology.
How Does Climeworks Work?
Climeworks' DAC technology works by pulling carbon dioxide (CO2) from ambient air using a network of modular collectors. These collectors, known as CO2 collectors, contain a filter material that selectively captures CO2 when air passes through them. This process, called CO2 capture from air or direct carbon capture, is at the core of Climeworks' carbon dioxide removal technology.
Once the CO2 is captured, the collectors are heated, releasing the CO2 in a concentrated form that can be stored underground or used for various applications such as carbon-neutral fuel production or carbonation of beverages. This carbon disposal process ensures the permanent removal of CO2 from the atmosphere.
The Benefits of Climeworks
Carbon Removal: Climeworks offers a scalable and efficient solution for removing CO2 directly from the atmosphere, helping to reduce the concentration of greenhouse gases and mitigate climate change. Their direct air capture technology provides a means for CO₂ removal and greenhouse gas removal on a large scale.
Versatility: The captured CO2 can be stored underground or utilized in various industries, including agriculture, food and beverage, renewable energy production, and materials production, thereby enabling a wide range of carbon-neutral or carbon-negative applications. This versatility makes Climeworks' technology a valuable tool in the fight against global warming.
Modularity: Climeworks' modular design allows for flexibility in deployment, making it adaptable to different geographical locations and scalable to meet varying carbon removal needs. This modularity is a key feature of their carbon removal machine and DAC plant designs.
Public Engagement: Climeworks' technology has garnered significant attention and interest from governments, corporations, and the public, raising awareness about the importance of carbon removal and climate change mitigation. The company's efforts have helped to promote the concept of CO2 compensation and the role of carbon capture technology in achieving net zero emissions.
Climeworks in Action
Climeworks has deployed several DAC plants worldwide, demonstrating the feasibility and effectiveness of its technology. One notable project is the Orca plant in Iceland, which captures CO2 from the air and injects it underground, where it mineralizes over time through a process called underground mineralization, effectively removing it from the atmosphere permanently. This process, known as DAC+S (Direct Air Capture and Storage), is a key component of Climeworks' carbon removal service. The company has also partnered with Carbfix, an Icelandic company specializing in the permanent storage of CO2 in basalt rock formations.
Another significant project is the Mammoth plant, which is set to become the world's largest direct air capture facility upon completion. This plant will significantly increase Climeworks' carbon dioxide removal capacity and contribute to their goal of achieving net carbon removal on a gigaton scale.
Climeworks' technology has undergone extensive life cycle assessment to ensure that it provides a net positive impact on the environment. The company's commitment to sustainability and minimizing its environmental impact is evident in its use of renewable energy to power its operations and its focus on providing high-quality removals.
The Future of Climeworks
As the urgency to address climate change grows, Climeworks' role in carbon removal is becoming increasingly vital. The IPCC (Intergovernmental Panel on Climate Change) has emphasized the need for carbon dioxide removal technologies alongside emissions reduction efforts to meet global climate targets. Climeworks' direct air capture technology is well-positioned to contribute to this goal as part of a broader CDR portfolio.
With ongoing research and development efforts, the company aims to further optimize its technology, reduce costs, and increase scalability to make carbon removal more accessible and affordable on a global scale. Climeworks is exploring various capture methods, including solvent-based capture and sorbent-based capture, to enhance the efficiency and effectiveness of its DAC technology.
