Carbon Capture and Storage: Examining the Cost Competitiveness
Environmental Business Review | Thursday, April 11, 2024
The CCS device needs a lot of energy to run, increasing emissions if that energy comes from fossil fuels. A thorough examination of CCS technology reveals that it occasionally produces more emissions than it absorbs. Studies highlighting the potential of CCS technology frequently omit a complete life-cycle survey of the CCS process, which leaves out important details about how inefficient the technology is.
Fremont, CA: In mitigating climate change, carbon capture and storage (CCS) is the newest and brightest gadget that will catch everyone's attention at COP 28. By absorbing carbon dioxide from industrial operations and injecting it underground, the method aims to cut emissions. Many oil and gas-producing nations, like the US and Canada, are looking to CCS to lower production emissions, and countries that rely heavily on coal, like China and India, are investigating the viability of integrating the technology into coal-fired power stations.
Even though the technology has generated a lot of attention, there are still a lot of unanswered questions regarding its viability, ongoing high costs, and past performance.

Carbon Capture and Storage
CCS technology aims to absorb emissions at a sizable source before their atmospheric release. This is not the same as carbon dioxide removal (CDR), which aims to retrospectively remove CO2 from the atmosphere by employing techniques like direct air capture technology or growing trees. When CCS is applied to the production of fossil fuels, its goal is to capture emissions produced during the extraction and processing of the fuels. However, it does not lessen most emissions released when the fuel is consumed.

Is CCS Cost Competitive?
The industrial process that CCS is used in, the concentration of the CO2, the distance it is carried, and the storage location all affect how much it costs. Most of the cost estimates are derived from modelling because there aren't enough projects in operation long enough to provide accurate long-term cost estimates.
Despite decades of technological advancement, the cost of CCS in the oil and gas industry has not decreased quickly. This is due to technical design's technical, complicated, multi-component nature, which slows innovation. Additionally, it must be carefully adapted for various uses; for example, CCS in cement manufacturing differs greatly from CCS in refineries. It seems improbable that CCS will witness the same rapid cost reductions as other technologies, including solar photovoltaics and electric vehicle batteries, have reached economies of scale.
To be commercially feasible, CCS in the fossil fuel industry still significantly depends on government subsidies due to its high cost. Simultaneously, oil and gas corporations worldwide allocate less than 1% of their capital to clean energy projects, including very little personal investment in CCS or renewable energy.
When evaluating the cost-effectiveness of carbon capture and storage (CCS) in the energy sector, it is important to compare it against alternative energy sources that can lower emissions by substituting fossil fuels. According to the IPCC, one of the most costly and ineffective mitigation strategies shortly is carbon capture and storage (CCS) in the energy sector.
