A power plant integrated with carbon capture and storage (CCS) can significantly reduce carbon emissions by up to 90% compared to ones without them. But this option comes with energy intensive limitations and an escalating climate crisis. Let us explore the blog to learn about problems with carbon capture and storage along with their hazards.
What are the Problems with Carbon Capture and Storage?
This method has growing concern due to the high prices, inefficiency, and multiple risks. These factors focus on the unpredictable nature of the storage systems that could lead to safety hazards and long-term viability issues. The dangers of carbon capture and storage are as follows:
1. Risk of Ground Leaks: Proper storage or maintenance of carbon dioxide is necessary otherwise it can escape into the surroundings. Moreover, in case of large-scale leaks atmospheric CO2 levels would significantly increase contaminating soil and polluting waterways. Additionally, if the gas reaches populated areas it may pose health risks to local communities.
2. Hazards of Infrastructure Development: The implementation of CCS infrastructure ends up facing issues like environmental impact, habitat degradation, and wildlife displacement. Moreover, these structures are at significant risk of leaks and disturbances caused by natural disasters.
Did you know even a minor amount of carbon leakage into the atmosphere as reported by the Intergovernmental Panel on Climate Change can immediately endanger human life? Moreover, vehicles and ships transporting carbon dioxide are at a constant risk of accidents, sinking, and grounding.
3. Continued Fossil Fuel Reliance: This storage method might promote the continued use of fossil fuels while neglecting pollution types like fine particles that potentially worsen the strain on ecosystems. Some companies may favor this technology rather than switching to renewable energy.
4. Emphasis on Enhanced Oil Recovery: The current CCS initiatives are primarily focusing on the method which includes injecting captured carbon dioxide into existing oil fields to increase the amount of extractable oil. Although it helps to reduce emissions from burned fuel but may lead to increased fossil fuel production.

5. Public Opinion Impact: There is a lack of awareness among the general population regarding such approaches which have the ability to impact the viability of CCS. The concerns related to injecting an invisible gas into the ground near residential areas with the safety trust of such techniques remain unresolved.
6. Elevated Expenditures: These programs are expensive and lack demonstrated effectiveness which makes it difficult to justify billions of dollars in investment. Despite significant global investment in such projects throughout these years, no commercial-scale plant has endured.
For example, the Petra Nova coal plant in Texas failed due to budgetary constraints and insufficient output.
7. Energy Intensiveness: This method needs more infrastructure and energy which increases the cost and energy demands. Despite recent initiatives to improve efficiency by allocating funds to minimize carbon dioxide emissions, the scale of carbon capture remains minimal in comparison to major polluters’ annual emissions. This is one of the reasons why carbon capture is a bad idea.

What are the Carbon Sequestration Problems?
It stores the captured carbon that leads to the listed drawbacks:
1. Cost Barriers: Addressing the expenses linked to carbon dioxide separation and capture is crucial to overcoming the challenges. It can be achieved by laying down a comprehensive strategy prioritizing efficiency enhancement and the use of non-carbon energy sources for cost-effective climate change mitigation.
2. Storage Reservoir Development: The issue of establishing safe and efficient storage reservoirs for sequestered carbon is important to address safety concerns and potential hazards. By addressing this, a successful reservoir can be developed with ensured reliable storage infrastructure.
3. Verification of Geologic and Ocean Reservoirs: Understanding the long-term fate of sequestered carbon dioxide and addressing concerns is critical for effective storage systems. It can be done by evaluating the viability of alternative storage methods such as geologic and ocean reservoirs that do present significant challenges.
