Each category employs distinct methods and technologies to effectively reduce greenhouse gas emissions.
How does pre-combustion capture work?
Pre-combustion capture works by converting fossil fuels into a mixture of hydrogen and carbon dioxide before combustion occurs. In this process, fossil fuels are subjected to gasification, where they react with steam and oxygen at high temperatures to produce syngas, which primarily consists of hydrogen and carbon monoxide. The carbon monoxide is then reacted with steam in a shift reactor to produce additional hydrogen and carbon dioxide. The carbon dioxide is subsequently separated from the hydrogen using various methods such as absorption or adsorption, allowing for the hydrogen to be used as a clean fuel while capturing the carbon dioxide for storage or utilization. This method is effective in reducing greenhouse gas emissions, as it captures up to 90% of the carbon dioxide produced during the process.

Mineral storage, also known as mineral carbonation, involves converting carbon dioxide into stable minerals through chemical reactions, a process that can occur naturally over geological timescales and is being researched for its potential to provide a permanent solution for carbon sequestration.
How does geological storage function?
Geological storage functions by injecting carbon dioxide (CO2) into deep underground rock formations, where it is trapped and prevented from entering the atmosphere. This process typically involves capturing CO2 emissions from industrial sources, compressing the gas, and then transporting it to a suitable geological site, such as depleted oil and gas fields or deep saline aquifers. The effectiveness of geological storage is supported by the fact that these formations have been naturally sealing gases for millions of years, ensuring long-term containment. Studies indicate that geological formations can securely store CO2 for thousands of years, making it a viable solution for mitigating climate change.
What are the benefits of utilizing ocean storage?
Utilizing ocean storage offers significant benefits for carbon capture and storage technologies, primarily by providing a vast and stable environment for long-term carbon dioxide sequestration. The ocean can absorb large quantities of CO2, with estimates suggesting it has absorbed about 30% of the carbon dioxide emitted by human activities since the industrial revolution. This natural process helps mitigate climate change by reducing the concentration of greenhouse gases in the atmosphere.
