Public Perception of CCUS: Overcoming the Myths and Misconceptions
As the world intensifies its efforts to tackle climate change, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a key technology in reducing carbon emissions from hard-to-abate industries like steel, cement, and energy production.

Despite its potential, public perception of CCUS is often clouded by myths and misconceptions. While some view it as a critical tool for achieving net-zero emissions, others remain skeptical about its efficacy, safety, and long-term sustainability. Understanding and addressing these misconceptions is crucial to gaining broader support for CCUS deployment.
This article explores the common myths surrounding CCUS and highlights the facts that can help dispel them. By clarifying the role of CCUS in mitigating climate change, we aim to foster a better-informed public perception of this vital technology.
Myth 1: CCUS Is Just a "Band-Aid" for Fossil Fuels
One of the most prevalent misconceptions about CCUS is that it serves as a temporary fix that enables industries to continue relying on fossil fuels, delaying the transition to renewable energy. Critics argue that CCUS allows companies to continue polluting, undermining global efforts to shift to cleaner energy sources like solar, wind, and hydropower.
Fact: CCUS is not a substitute for renewable energy but rather a complementary technology that addresses emissions from industries that are difficult to decarbonize. While renewable energy is vital for reducing emissions in the power sector, CCUS is critical for industries like cement, steel, and chemicals, which produce significant emissions that cannot be easily eliminated by renewable energy alone. CCUS also plays a role in capturing CO₂ from bioenergy production and direct air capture, supporting efforts to achieve negative emissions. This combination of technologies is necessary to meet the ambitious net-zero targets set by many nations.
Myth 2: Carbon Storage Sites Are Unsafe and Prone to Leaks
Another major concern revolves around the safety of carbon storage sites, particularly the fear that CO₂ stored underground could eventually leak, causing environmental and health hazards. Some members of the public worry that such leaks could result in dangerous concentrations of CO₂ being released, potentially harming nearby communities.
Fact: Carbon storage is a well-researched and carefully regulated process. When CO₂ is injected into geological formations such as depleted oil and gas reservoirs or deep saline aquifers, it is stored thousands of meters below the surface, often trapped by layers of impermeable rock. These formations have held natural gas and oil for millions of years, making them ideal for long-term CO₂ storage.
Extensive monitoring systems are in place to ensure that the CO₂ remains securely stored. Modern storage facilities use advanced technology to monitor pressure, temperature, and other factors in real time, ensuring the integrity of the storage site. In regions where CCUS has been implemented, such as the Sleipner project in Norway, CO₂ has been safely stored for over 20 years without leakage. This demonstrates that carbon storage can be a safe and effective way to reduce emissions over the long term.
Myth 3: CCUS Is Too Expensive and Will Never Be Scalable
There is a common perception that CCUS technologies are prohibitively expensive, making them an impractical solution for large-scale climate mitigation efforts. This belief often stems from the high costs associated with early-stage CCUS projects, which require significant investment in infrastructure and technology development.
Fact: While early CCUS projects were indeed costly, the technology has evolved, and costs are expected to decline as CCUS deployment scales up. Similar to renewable energy technologies like wind and solar, which experienced dramatic cost reductions as they became more widespread, CCUS is expected to follow a similar trajectory. Government incentives, carbon pricing mechanisms, and growing private sector investment are driving down costs, making CCUS increasingly affordable.
Moreover, the cost of inaction on climate change far outweighs the cost of implementing CCUS. Without solutions to capture and store emissions, industries will face increasing regulatory pressures, potential carbon taxes, and higher costs associated with climate change impacts, such as extreme weather events and rising sea levels. By investing in CCUS today, industries can reduce long-term costs and contribute to global efforts to mitigate climate change.
Myth 4: CCUS Technologies Are Ineffective and Unproven
Skeptics often argue that CCUS is an unproven technology that is not yet ready for widespread adoption. This misconception is rooted in the belief that CCUS is still in the experimental phase, with limited practical applications to date.
"Dispelling misconceptions about CCUS is key to unlocking its full potential and driving a sustainable, low-carbon future."
Fact: CCUS is not a new or experimental technology—it has been successfully deployed in numerous projects worldwide. For example, the Boundary Dam Power Station in Canada has been capturing CO₂ since 2014, and the Petra Nova project in the U.S. demonstrated the feasibility of large-scale carbon capture at coal-fired power plants. Additionally, CCUS has been used in enhanced oil recovery (EOR) for decades, proving its ability to capture and store CO₂ effectively.
While challenges remain in scaling CCUS to the level needed to meet global climate goals, ongoing innovation, research, and investment are rapidly advancing the technology. As countries and companies ramp up their commitments to reduce emissions, CCUS will play an increasingly critical role in helping hard-to-abate sectors achieve significant reductions.
Myth 5: CCUS Only Benefits Large Polluters
Some critics argue that CCUS is primarily designed to benefit large polluting industries, such as oil and gas companies, by giving them a way to continue their operations without fully addressing their environmental impact.
Fact: While it is true that large industries are among the main users of CCUS, the technology benefits everyone by reducing overall emissions and helping mitigate climate change. CCUS allows industries to capture carbon emissions that would otherwise contribute to global warming, ultimately benefiting communities, ecosystems, and the global climate.
In addition to capturing emissions from large industrial facilities, CCUS can also be used in direct air capture technologies, which remove CO₂ directly from the atmosphere, providing a broader environmental benefit. Furthermore, the deployment of CCUS can create new green jobs and economic opportunities in regions where industrial decarbonization is needed, supporting a just transition to a low-carbon economy.
As with any emerging technology, CCUS faces its share of myths and misconceptions, many of which stem from a lack of understanding about its potential benefits and limitations. By dispelling these myths and providing accurate information, we can foster greater public acceptance of CCUS as a critical tool in the fight against climate change.
CCUS is not a "silver bullet" but rather an essential part of a broader strategy to decarbonize industries, reduce emissions, and protect the environment. As governments, industries, and communities come together to address the climate crisis, a clearer understanding of CCUS will help build the support necessary for its successful deployment. The path to a net-zero future will require innovative solutions like CCUS, and overcoming public skepticism is key to realizing its full potential.
