Why Is It Impossible for Carbon Capture to Solve the Climate Crisis?

Global leaders and state officials are largely relying on technological advancements to solve the climate change crisis. The most prominent and popular idea among these technological solutions is capturing carbon pollution in the atmosphere and permanently burying it underground. At first glance, this method may seem like a highly practical and applicable strategy for reducing greenhouse gas emissions without halting industrial production and while maintaining our current lifestyle. However, in-depth analyses and scientific assessments of the issue reveal that, considering the current limitations of this technology, it is conceivably impossible for it to achieve what is expected. Unfortunately, during the transition to a low-carbon future, such quick fixes can mislead societies and governments, delaying the implementation of real and urgent measures.

A comprehensive investigation conducted by ProPublica and Drilled has revealed that advocates of carbon capture and storage (CCS) technology have intentionally or unintentionally ignored critical facts. For over Kırk yıl, oil companies have been funding extensive research at prestigious universities to find climate change "solutions" that would not require the public to stop using fossil fuels. To continue their own operations, these companies have exaggerated the potential of CCS technology and, despite the evidence, have tried to convince the world that this method will work. However, for the technology to operate at its currently envisioned scale, the world would need to mobilize unimaginably vast financial, physical, and time resources. Furthermore, even if all these massive resources and efforts were spent, it is stated that it might be technically impossible to trap such an immense amount of carbon dioxide underground safely and permanently.

Despite the optimistic projections of respected institutions such as the Uluslararası Enerji Ajansı (IEA), the real-world, on-the-ground implementation of the technology has never approached targeted levels. For instance, in 2008, the IEA projected that by 2025, 1.6 milyar tons of carbon dioxide needed to be buried underground globally every year to prevent dangerous levels of global warming. However, at the current stage, the amount of globally and permanently stored CO2 is less than the carbon dioxide emitted into the atmosphere by a single large power plant in one year. Despite this, because small-scale laboratory tests and trials have yielded successful results, CCS advocates are spreading unfounded optimism that the technology could take off on a global scale at any moment. In addition, the slowness of the international community's response to the climate crisis and existing political deadlocks force decision-makers to rely on this entirely experimental technology.

To prove the effectiveness of carbon capture technology, some experts attempt to cite CO2 injection processes underground during oil extraction as examples. However, scientists and researchers explicitly emphasize that this process, called enhanced oil recovery, is not actually designed to store carbon permanently. On the contrary, this process is mostly used to increase efficiency from old oil wells to extract more fossil fuels, and it is regulated much less strictly. Therefore, such industrial applications create a misleading perception that CCS has proven successful as a real climate crisis solution. This misleading perception serves as a dangerous excuse that causes countries around the world to delay the difficult but essential measure of rapidly moving away from fossil fuels.

Despite this, global leaders today are relying on carbon capture technology more than ever and are placing it at the center of future climate strategies. In fact, it is seen that the scientific models used in the most recently published global climate assessment reports by the Birleşmiş Milletler are built on the assumption that this technology will inevitably succeed. Representatives of the Uluslararası Enerji Ajansı and BM experts who prepared these models argue that their projections actually reflect what the world must do and what it must achieve to avoid the devastating effects of extreme global warming. However, underlying this approach is a sense of desperation created by the inability to scale existing and developed renewable energy and efficiency solutions quickly enough. Ultimately, the misconception that carbon capture technology alone can solve the climate crisis remains a major risk that delays the radical and transformative steps that must be taken for the future of our planet.
