Carbon capture and storage (CCS) has been hailed as an innovative solution to help Britain reduce its greenhouse gas emissions. But what exactly is CCS and how effective can it be? Prime Minister Rishi Sunak is a strong supporter, as evident from his recent announcement of investing £20 billion to build two CCS facilities. However, opponents remain skeptical, considering CCS to be a fledgling science that has not yet proven its ability to significantly reduce carbon levels in the atmosphere. In order to gain a deeper understanding of CCS and its controversies, let’s take a closer look at how it works.
CCS technology is designed to capture carbon dioxide (CO2) emissions from power plants, industrial processes, and other sources, and store them permanently underground. This serves as a greener alternative to releasing the emissions into the atmosphere. The government estimates that a CCS plant could potentially store a massive 78 billion tonnes of carbon, which is equivalent to the weight of 15 billion elephants. While there are other options being explored to reduce CO2 emissions, CCS remains the primary solution for large industrial sources.
In operation, CCS involves capturing waste gases at the source of their creation, such as power plants and industrial facilities. The captured CO2 is then transported to underground storage sites, either through pipelines or road vehicles and ships when the storage site is located far away. These storage sites typically consist of underground caverns, like depleted oil or gas reservoirs, or porous rock formations known as saline aquifers. The CO2 is securely stored in these locations and continuously monitored to prevent leakages.
A slightly different process, known as carbon capture, utilization, and storage (CCUS), involves reusing the captured CO2 in various industrial applications, such as converting it into plastics, concrete, or biofuel. This approach provides an additional benefit of utilizing the captured carbon for productive and sustainable purposes.
Despite its potential benefits, CCS is not without controversy. Critics argue that it encourages continued reliance on fossil fuels instead of transitioning to renewable energy sources. Environmental organizations like Friends of the Earth have expressed concerns that CCS merely promotes the use of costlier and dirtier fossil fuels. Moreover, safety concerns exist regarding potential underground CO2 leaks and their impact on water supplies and underground pressure. The long-term effects of CO2 storage and transportation on the environment are still not fully understood. Additionally, the process of separating and storing carbon dioxide itself requires substantial energy, which could decrease the overall efficiency of power plants.
While CCS has been operational in the United States since 1972, the UK is yet to have its first CCS facility. However, a CCUS facility was established in Cheshire last year, focusing on utilizing emitted CO2 rather than storing it. As part of the £20 billion investment, the UK plans to establish CCS facilities in Scotland and the Humber region. These facilities will be situated near the coast to enable the transportation of captured CO2 for underwater storage. Additionally, the UK government has granted around 100 new oil and gas licenses in the North Sea, leading to concerns about the potential increase in oil and gas extraction.
In conclusion, CCS offers a promising technology to mitigate carbon emissions and combat global warming. However, its effectiveness and drawbacks continue to be debated. Further research, development, and careful implementation are necessary to address the concerns surrounding CCS and ensure its role in reducing carbon levels while transitioning to sustainable energy sources.
