Everything you need to know about carbon transportation

The meaning of “carbon transportation.”

Carrying carbon from one location to another is the definition of carbon transportation. Carbon has a natural life cycle called the carbon cycle. However, carbon transportation is the physical movement of carbon dioxide (CO2) emissions from the capture site to the point of utilization or storage in sectors such as the energy industry.

Why is it necessary to move carbon if it is already everywhere?

There has been an immediate increase in the amount of CO2 in the atmosphere due to anthropogenic (artificial) CO2 produced in activities like electricity generation, which has contributed to global warming. However, these emissions can be absorbed as part of carbon capture and storage (CCS). Finally, the CO2 is piped to underground caverns where it will remain trapped. CO2 can be captured and stored before it can enter the atmosphere to reduce its impact on global warming. Negative-emissions processes, like bioenergy with carbon capture and storage (BECCS) and direct air capture and storage (DACS), use CCS to remove CO2 from the air for good. Carbon capture and storage necessitates moving carbon from its point of collection to a permanent storage location. This necessitates transport from an electrical generating facility or manufacturing plant to a salty aquifer or depleted oil and gas reserves.

There were 27 CCS facilities in operation worldwide as of September 2021, with a total capacity to capture about 40 Mtpa CO2. It has been calculated that the sandstone rock formations beneath the North Sea have the potential to store 70 billion tonnes of CO2 from the United Kingdom alone.

In what ways does carbon get around?

Transporting carbon dioxide (CO2) can be done via truck or ship, although a pipeline is the most popular and efficient option. Using pressure, pipelines can transport virtually any gas. When the pressure is high, gases move to low-pressure locations. If gas is compressed to a high enough pressure, it can be transported to other sites.

Gas pipelines, especially those used to carry CO2, are widespread worldwide. For instance, the United States is home to more than 50 CO2 pipelines, which collectively span over 6,500 kilometers and move around 68 million tonnes of CO2 annually.

Compressed gas occupies less space than liquid, solid, or hydrated gas. Therefore, it is common practice to compress captured CO2 until it becomes a supercritical fluid before transporting it.

CO2 in its supercritical state has the density of a liquid but the viscosity (thickness) of a gas, making it more amenable to pipeline transfer. Furthermore, its consistency is one hundred times less than liquid water and is 50-80% less dense than water.

Because of this, more of it can be loaded onto ships at once, and it will flow more smoothly via pipelines and eventually into geological storage locations.

Is Carbon Transport Safe?

Transporting carbon dioxide by pipeline or ship is just as safe as transporting oil or natural gas, and many of the pipes currently used for these fuels can be converted for CO2 transport instead.

Captured CO2 must be dry, devoid of impurities that could impair pipeline operations, and meet stringent purity and temperature criteria for CCS projects to enable the safe usage of CO2 pipes.

Research is being conducted to find best practices, materials, and technologies to optimize the process of carbon capture and storage (CCS), which is still a relatively new field despite the growing number of CCS transport systems worldwide. This entails investigating possible dangers and learning methods for sealing and fixing leaks.

The Health and Safety Executive is responsible for ensuring the safety of all natural gas pipelines in the United Kingdom. The law can provide a solid basis for CO2 transport control and safeguard the security of pipelines, pressure systems, and offshore facilities.
