Doug Chan, Chief Operating Officer at Climeworks, discusses the monumental launch of the Mammoth, the world's largest direct air capture facility in Iceland. He dives into the challenges faced during its construction and the innovative solutions developed amidst harsh winter conditions. Chan shares insights on scaling technology, managing risks, and the crucial role of teamwork. The conversation highlights the rapid advancements in direct air capture and the strategic planning needed for future projects, including plans for an even larger facility in Louisiana.
Climeworks successfully launched the Mammoth facility, demonstrating the feasibility of scaling direct air capture technology to a significant level.
The journey involved overcoming technological challenges and harsh winter conditions, highlighting the importance of teamwork and adaptability in innovation.
Deep dives
Launching a Revolutionary CO2 Capture Plant
Climeworks opened its largest direct air capture plant, named Mammoth, on Christmas Eve 2023, positioning it as the world's biggest operational facility for capturing carbon dioxide. The team, including COO Doug Chan, undertook significant work over the holidays to ensure the plant's functionality, culminating in a moment of celebration as they successfully stored their first tons of CO2. This marked a critical milestone in demonstrating that direct air capture technology can be implemented on a large scale. Chan emphasized the urgent need for such technologies to address climate challenges effectively and underscored the motivation within his team to push forward despite the holiday setting.
Technological Innovations in Direct Air Capture
Climeworks has pioneered direct air capture technology that vacuums CO2 from the atmosphere and stores it underground. The company evolved from initial small-scale experiments, such as the first commercial plant Capricorn in Switzerland, to larger facilities like Orca and now Mammoth, which integrates advanced capture and storage solutions. Upgrades include transitioning from Generation 1 to Generation 2 filter technology, which is designed to enhance efficiency and reduce costs. The focus on permanent CO2 storage, as opposed to utilization, is essential for scaling carbon removal technologies, aiming for significant climate benefits.
Navigating Challenges of Scaling Up
As Climeworks moves toward scaling its operations, the design and manufacturing of capture units present both opportunities and challenges. With Mammoth featuring 72 collector containers compared to eight in previous plants, Doug Chan and his team invested in redesigning these modules for improved mass manufacturability. The construction process also faced challenges, including harsh winter conditions in Iceland and operational hiccups such as issues with new filter designs that required quick adaptations. Nonetheless, maintaining a proactive and collaborative team spirit allowed them to address these hurdles effectively while continuing to refine their technology.
Funding and Market Demand for Carbon Removal
Securing financing is critical for scaling carbon dioxide removal technologies, with future projects like Cypress in Louisiana requiring significant investment. Doug Chan highlighted the importance of market demand in driving the growth of the carbon removal sector, which relies heavily on businesses committing to CO2 offsetting. Recent federal funding initiatives, such as those from the bipartisan infrastructure law, may stimulate this demand by providing necessary subsidies and support for new projects. Ultimately, establishing a robust voluntary and compliance market for carbon credits is essential for the long-term success of industries like Climeworks that aim to contribute meaningfully to climate goals.
On Christmas Eve 2023, Doug Chan wasn't celebrating with family. Instead, he was in Hellisheiði, Iceland with his team, preparing to commission Mammoth — what would become the world's largest operational direct air capture facility.
Getting there wasn't easy. After building two successful smaller plants, Climeworks faced its biggest challenge yet in attempting a 10x scale-up of its Orca plant. When the team broke ground, they discovered issues with their newly designed equipment that forced tough decisions. And Iceland's harsh winter conditions complicated both construction and operations.
In this episode, Lara Pierpoint talks to Douglas Chan, chief operations officer at Climeworks, about proving and scaling direct air capture technology. They discuss managing technology risks, choosing the right partners — and what's next as Climeworks plans for an even bigger facility in Louisiana.
