General Information and objectives of the international project

With energy production sectors based mostly on fossil fuel combustion, many Black Sea region countries are interested in applying CCS for reducing their CO2 emissions, including the development of CO2 transportation infrastructure on their territory. Although the technology related to CO2 transportation is considered to be known from similar activities (e.g. natural gas networks), there are additional specific design considerations and a number of fundamentally important risks and hazards specific for CO2 transportation that must be investigated.The international research project aims to address:

  • the thermodynamic analysis and modelling of pure CO2 and its mixtures with other impurities, such as H2S, N2, water etc, over a wide range of temperatures and pressures and the design of CO2 transportation pipelines,
  • the risk analysis of important risks related to CO2 pipeline transportation, namely landslide, seismic, corrosion, design and construction error risk. Risk assessment guidelines will be developed based on the obtained results.

The Romanian gas transmission company has expressed their willingness of applying the research results, as the risks related to CO2 transportation by pipeline is a subject of great interests for them. At the end of the project, the Romanian gas transmission company will be trained on the project topics having as main support the prepared guidelines.

The results of the project are expected to have a significant impact on the development of the principles of engineering and construction for CO2 transportation pipelines and of the technical prescriptions for their design, construction and operation.

Objectives of the national project

The objective of the national project is to research possible risks at landslides associated with CO2 long distance pipeline transportation, in order to create a risk assessment guidance based on the obtained results and finally train the pipeline operators.

Estimated results of the national project

The expected results of the project are as follows:

  • identification of potential sites of CO2 transportation pipelines located in areas with high geological risk;
  • determination of safe locations and appropriate installation techniques for pipelines crossing areas with high risk of landslides;
  • determination of the basic principles for engineering, construction and operation of high-pressure CO2 transportation pipelines crossing areas with high risk of landslides, useful in the development of technical regulations for the design, construction and operation of these pipelines.

Scientific results obtained so far

  • determination of the potential areas for CCS implementation, including potential locations of the future CO2 transportation pipelines;
  • geomorphological classification of the areas crossed by CO2 transportation pipelines;
  • identification of the areas prone to landslip;
  • field investigations and mapping on sites prone to landslides;
  • development of the geological models and establishment of the elements for slope stability calculation;
  • analysis and statistical processing of information;
  • correlation and systematization of data resulted from Field investigations and laboratory Analysis;
  • determination of the reference model;
  • performing the stability calculation for a location in the investigated area;
  • determination of causes and risk factors for slip-prone planes and slopes;
  • determination of the appropriate technologies for pipeline installation in areas with high risk of landslides.

International workshop

On the 2nd of November 2012, the Institute for Studies and Power Engineering (ISPE), together with the members of the CO2TRACCS project international consortium – National Technical University of Athens (NTUA), Technical University of Sofia (TUS) and Middle East Technical University (METU), has organized the international workshop titled „CO2 Transportation Risk Assessment for Carbon Capture and Storage”, at its headquarters in Bucharest, Romania. The event was organized as part of the dissemination activities of the CO2TRACCS project funded under Black Sea ERA.NET Pilot Joint Call.

The main objective of the workshop was to disseminate preliminary results of the CO2TRACCS research project but also to share knowledge and experience gained in the field by internationally recognized companies.
