Aircraft Seizure and Carbon Capture Recovery Operation

Aircraft Seizure and Carbon Capture Recovery Operation

Direct air capture (DAC) technology, a promising solution to combat climate change, is being employed by companies like Climeworks and Occidental Petroleum. This technology, which directly removes historic and excess carbon dioxide (CO₂) from the atmosphere, contributes to net negative emissions and could potentially help reverse global warming.

However, DAC faces several critical concerns and debates surrounding its climate impact and feasibility.

Energy Consumption and Costs

Current DAC systems are energy-intensive, which can limit their climate benefits if the energy source is not renewable. Despite advances like Climeworks’ Gen 3 technology, which halves energy use and doubles capture rates, powering DAC at gigaton-scale removal levels remains a challenge. Costs can be prohibitively high, with estimates reaching up to $5,000 per ton of CO₂ removed, much higher than the target of around $100 per ton needed for large-scale viability.

Scale and Real-World Effectiveness

While DAC is progressing from pilot to industrial scales with dozens of plants commissioned and more planned, some companies (including Climeworks) have struggled to capture net carbon beyond their own operational emissions, raising questions about current effectiveness in actual carbon reduction.

Use of Captured CO₂

The fate of the captured CO₂ sparks debate. When used for enhanced oil recovery, which Occidental Petroleum and others also engage in, the carbon is often not truly removed from the carbon cycle since it results in additional fossil fuel extraction and combustion. Alternative uses, such as creating carbon-negative materials, offer more durable storage but are not yet widespread.

Environmental and Ecosystem Considerations

DAC does not inherently provide ecosystem co-benefits like reforestation might, and its resource needs—land, water, energy—could cause indirect impacts if scaled without careful planning.

A Path Towards Climate Justice

Despite these challenges, experts like Celina Scott-Buechler, a DAC researcher at Stanford University and senior resident fellow at Data for Progress, urge companies to give communities ownership and decision-making power over the plants. Nawaz and Scott-Buechler believe carbon dioxide removal will play an important, albeit small, role in climate action, and they see a path where it aligns with climate justice.

The Future of DAC

The large-scale implementation of DAC technology is under rapid evolution. Companies like Climeworks are building new sites, such as the Mammoth facility in Iceland, which boasts an annual CO₂ removal capacity of 36,000 tons, an order of magnitude improvement over the Orca facility. Occidental Petroleum has acquired Carbon Engineering and plans to deploy 100 large-scale DAC plants by 2035, including a facility in west Texas called Stratos.

However, skepticism remains regarding how quickly and extensively DAC can contribute to reaching global climate targets. A substantial price drop is possible later in the process, such as when heating the filters to detach CO₂, according to Merritt Dailey, a DAC researcher.

The industry holds a vice grip over COP28, the flagship climate conference in the petrostate United Arab Emirates (UAE), and DAC is being used as a trojan horse. A whistleblower has alleged that consulting firm McKinsey, whose clientele includes ExxonMobil and Aramco, advised COP leadership to lower decarbonization goals and make up the difference with carbon dioxide removal technology.

Research is needed to ensure that carbon dioxide removal aligns with progressive values, with a focus on understanding where money is going, who benefits, and who bears the burden. Graphyte's announcement that it can turn plant waste into carbon-rich bricks that can be buried deep underground, with a cost of around $100 per ton, offers a potential solution to the high costs associated with DAC.

By midcentury, it's estimated that we'll need to remove billions of tons of carbon dioxide to stay below 2°C of warming. Foley of Project Drawdown warns against fossil fuel companies using DAC as a smokescreen for continued emissions, stating that it's trading seconds of emissions for decades of PR talking points. The U.S. recently invested $3.5 billion towards new DAC hubs, signalling a commitment to this developing technology.

In summary, DAC technology is a promising but still developing tool in the climate change mitigation portfolio. Its ability to physically remove CO₂ from the air can help address historic emissions, distinguishing it from technologies focused only on preventing new emissions. Yet, the overall climate impact heavily depends on achieving breakthroughs in reducing energy demands, lowering costs, ensuring genuine carbon removal and sequestration, and managing ecological effects. The technology is under rapid evolution, but skepticism remains regarding how quickly and extensively DAC can contribute to reaching global climate targets.
