The "security police" of the greenhouse effect is called CCUS?

Author: Duan Yuechu

Introduction: As the global climate change problem becomes increasingly serious, reducing greenhouse gas emissions has become a top priority. Carbon capture, utilization and storage (CCUS) technology is gaining more and more attention as a potential solution. This article will introduce the working principle of CCUS technology, existing technologies and their applications, as well as Aramco's cutting-edge exploration in this field.

1. How does CCUS technology work?

CCUS technology mainly achieves the capture, utilization and storage of carbon dioxide through the following steps:

1. Capture: CCUS technology can capture CO2 emissions at the source or directly from the air. Capture methods include pre-combustion, post-combustion or oxy-combustion technologies, as well as direct air capture (DAC).

2. Transport: The captured CO2 emissions are then transported to a storage location. The transport method can be pipelines, ships or other means of transport.

3. Storage: CO2 is injected into geological structures, such as oil and gas reservoirs or rock formations, to achieve long-term storage and prevent it from entering the atmosphere.

4. Utilization: The captured CO2 can be used to produce industrial products such as cement, chemicals, fuels, etc., or converted into other valuable materials.

2. Types and Applications of CCUS Technologies

1. Capture technology: Capture CO2 from exhaust or reformed gas using pre-combustion, post-combustion or oxy-combustion technologies.

2. Storage technology: The captured carbon dioxide is deposited in geological structures, such as oil reservoirs and gas reservoirs.

3. Enhanced oil recovery: By injecting carbon dioxide, the properties of the reservoir are changed and the efficiency of oil extraction is improved.

4. Utilization technology: The captured carbon dioxide can be directly used in cement production, or converted into chemicals, fuels, etc.

5. Mobile carbon capture technology: Capturing CO2 from mobile sources (e.g. cars, trucks) and storing it on board ships for later storage or utilization.

6. Bioenergy Carbon Capture and Storage Technology: Extracting and storing carbon dioxide from biomass, which is itself a renewable energy source.

3. Aramco’s Exploration in CCUS

As the world's largest integrated energy and chemicals company, Aramco has been committed to promoting the development and application of CCUS technology. The following are some of Aramco's latest projects in the field of CCUS:

1. Enhanced Oil Recovery: A carbon capture and storage demonstration project is underway at the Uthmaniyah reservoir in Saudi Arabia to enhance oil recovery and reduce carbon dioxide emissions.

2. Construction of a CCUS Center in Jubail: Working with partners SLB and Linde to build one of the world’s largest CCUS centers in the Jubail Industrial Zone in Saudi Arabia’s Eastern Province.

3. Promote changes in transportation technology: Develop mobile carbon capture and storage technology to reduce CO2 emissions from cars and trucks.

4. Protecting mangroves and cultivating algae: Converting carbon dioxide into valuable bioproducts by protecting, planting and restoring mangroves, and cultivating algae.

Summary: CCUS technology, as an important means to reduce greenhouse gas emissions, has great potential and application prospects. Aramco's exploration and project practice in the field of CCUS have provided strong support and reference for the global carbon emission reduction cause. With the continuous development and improvement of technology, CCUS technology will play an important role in addressing global climate change issues.
