CO2

På dansk

Evida will establish a scalable CO₂ pipeline infrastructure built for specific projects. A CO₂ pipeline will initially connect a few large CO₂ suppliers with a few large CO₂ recipients. Once in place, smaller suppliers can also connect, and Power-to-X plants can receive a stable CO₂ supply to produce future green fuels. It is like a highway that gradually gets more on- and off-ramps.

This is how we will design the CO₂ infrastructure of the future

Small pipelines

Evida will initially establish small pipelines that run from each CO2 supplier to a collection point, from where the CO2 will be transported in a larger pipeline. The smaller pipes transport CO2 at a pressure of 20-30 bar, which is about 10 times the pressure in a car tire. The smaller pipes can vary in size depending on the amount of CO2 to be transported and will be buried about one meter underground.

Compressor station as a collection point

The collection point for the smaller pipelines is a compressor station, where the CO2 is further compressed to a pressure of 100-130 bar. At this pressure, the CO2 transitions from being a gas to becoming as dense as a liquid. The advantage of transporting the CO2 in this form is that large amounts of CO2 can be moved through a relatively narrow pipe without friction, as CO2 under this pressure still flows like a gas. The compressor station is designed and located to blend into the landscape and be as concealed as possible.

Larger pipelines

The larger pipeline that transports CO2 from a compressor station will be buried about one and a half meters underground. The purpose of the pipelines will determine where and how they end. This could be a CO2 storage site on land, a port for shipping, or eventually a Power-to-X plant for producing sustainable fuels.

CO2 purification

The captured CO2 may contain other substances that need to be removed before it is sent into a pipeline to protect the pipe material. This could include water, so the CO2 must be dried to protect the pipe from corrosion.

Energy-optimized pipeline infrastructure

The purpose of the pipelines will determine where and how they end. If a pipeline is established to transport CO₂ for underground storage on land, the pressure of the CO₂ will be used to pump (inject) it into the ground.

If it leads to a port suitable for shipping CO₂ for offshore storage, the CO₂ will need to have a different pressure and temperature in the ship’s tanks. It is important that this conversion is well thought out to maximize the reuse of both thermal energy (heat and cold) and pressure (electricity).

The same energy utilization opportunities apply if the pipeline transports CO₂ to Power-to-X plants, and the CO₂ pipeline infrastructure can handle these different types of CO₂ recipients with different needs simultaneously.

Throughout the value chain, the focus will be on using as little energy as possible and reusing as much energy from the processes as possible.
