CO2 transport ships – a necessity of the future?

Carbon dioxide emissions are considered one of the main causes of global warming. The European Union, in particular, is very keen to significantly reduce these emissions. One of the ideas for solving this problem is capturing CO2 and storing it in geological structures. The projects being prepared assume the use of depleted oil fields, for example in the North Sea, for this purpose. To achieve this, vessels are needed to transport CO2 from land to sea. The article presents a proposal for such vessels, as well as the problems that must be taken into account during their design.INTRODUCTION
Carbon dioxide (CO2) is recognized as one of the main greenhouse gases that significantly contributes to global warming. According to data collected by
NOAA at a laboratory in Hawaii, the CO2 concentration increased from 314 ppm in March 1958 to 390 ppm in February 2011. In recent years, the observed increase in concentration has been
2 ppm per year.[8] The thesis is accepted that: for the global temperature not to rise by more than 2ºC, the CO2 concentration in the air should not exceed 450 ppm.
To stop the process of global warming, various programs for reducing greenhouse gas emissions are being introduced. One of the technologies being developed is the idea of capturing carbon dioxide and storing it later in geological structures. These can also be depleted oil fields under the seabed. For the transport of captured carbon dioxide, underwater pipelines or specially designed ships can be used, which is the subject of this article.
1. CURRENT STATE OF RESEARCH IN THE FIELD OF CAPTURE, TRANSPORT
AND STORAGE OF CO2
Reducing carbon dioxide emissions is therefore becoming a priority for many countries.
The European Union, in particular, is determined in the fight to reduce CO2 emissions and is funding many projects related to this. Currently, several demonstration projects are being implemented involving the capture, transport, and storage of carbon dioxide – Carbon Capture and Storage (CCS). The projects involve capturing the gas in facilities that are mainly responsible for its emission into the atmosphere, such as: power plants (especially coal-fired), cement plants, refineries, and other large industrial plants. Subsequently (…)
