CCS (carbon capture and storage) projects are an important element of the energy transition and a solution for the energy industry struggling with high prices of CO2 emission allowances. For the time being, no project has been launched in Poland that would consist in injecting CO2 into an underground formation for permanent storage. In November last year, LOTOS Petrobaltic S.A. together with its partners Grupa LOTOS S.A. and Grupa Azoty S.A. published the "Green Book for the development of CCS projects in Poland". The article below addresses the most important issues identified through an analysis of the legislative environment, both domestic and international, as well as technical aspects that need to be taken into account to implement the first CCS project in Poland. The authors indicate the B3 oil field in the Baltic Sea area as a potential pilot for the commencement of this type of activity in our country. Depleted gas and oil reservoirs are used around the world as storage facilities for CO2 due to confirmed tightness and appropriate parameters of such structures. In addition, the article presents an example of a CCS project launched in the Netherlands (Porthos) and the financing method for such projects.

Energia geotermalna jest jednym z odnawialnych źródeł energii. Przedstawiono wiadomości dotyczące jej zasobów, potencjału energetycznego, rodzajów oraz sposobów gospodarczego wykorzystania. Przedstawiono innowacyjne koncepcje zastosowania ditlenku węgla jako nośnika energii geotermalnej w konwencjonalnych hydrotermalnych systemach oraz we wspomaganych systemach geotermalnych (EGS), a także wynikające z tego potencjalne korzyści w postaci upowszechnienia wykorzystania światowych zasobów geotermalnych z jednoczesną geosekwestracją antropogenicznego ditlenku węgla.

A review, with 74 refs., of geothermal energy potential resources, its types and methods of economic use. The use of CO₂ as a carrier of geothermal energy in conventional hydrothermal systems and enhanced geothermal systems were presented, as well as the use of geothermal resources with simultaneous geosequestration of anthropogenic CO₂.

Shale gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020. Carbon dioxide capture and storage (CCS) is a set of technologies for the capture of CO2 from its anthropogenic point sources, its transport to a storage location, and its geosequestration. This is only one, though very important, option in a portfolio of actions to fight the increase of atmospheric CO2 concentration and to mitigate climate change, while at the same time allowing for the continued use of fossil fuels. Deployment of CCS technologies is expected to be limited in the next 5-10 years, but to contribute significantly to the reduction of CO2 emissions 20 years from now. Capture of CO2 using existing separation techniques can be applied to large point sources, i.e. power plants or industrial plants; CO2 can be easily transported over large distances using pipelines and ships; finally CO2 can be permanently stored in suitable deep geological formations, namely deep saline aquifers, oil or gas reservoirs, and unmineable coal seams, or it can be fixed in carbonates. The paper deals with the innovative method of carbon dioxide storage coupled with gas shale fracturing and methane recovery developed in the Military University of Technology. It allows to effectively mine the shale gas and to store carbon dioxide in shale rock. It must be noticed that CO2 pollution is a very important problem in Poland, because of European Union CO2 limits. Also carbon dioxide thermodynamic process of decompression numerical calculation, which simulates the injection of the cold liquid gas into the shale formation (high temperature and pressure conditions) and its influence on shale rock fracturing as well as initial experimental verification of the method was presented in the paper.
