Underground storage of carbon dioxide may be potential technology to decrease of
greenhouses gases emission, usually from industry sources. There are a number of existing
technologies, including chemical absorption, adsorption, cryogenic processes, and membranes, that
can separate carbon dioxide (CO2) from the flue gases emitted during power plant operation.Sequestration of CO2 is complex process of capture, transport and deep injection into geologic
formation (including the ocean, aquifers, and depleted oil and gas wells).
Because sequestration is expensive process – various economical variants are proposed- one
of the best are: enhanced oil recovery with CO2 (EOR-CO2), the `second is process of enhanced coal
bed methane (ECBM). The experimental projects of ECBM in Silesia (“Recopol”) is in pilot phase.
The Recopol project the first sequestration pilot onshore in Europe, inevitable to deal with all “soft”
issues (permits, contracts, opposition, etc.) related to this kind of innovative projects. The lessons
learned in this operation can possibly help to overtake start-up barriers of future CO2 sequestration
project in Europe.
The other carbon dioxide sequestration combined with Enhanced Oil Recovery (EOR) is
designed for “Jastrzabka Stara” field. The calculation of injection process show, that injection of 23
mln Sm3 is possible. Sequestration of CO2 during oil production is possible, and results from this
process may be useful during planning other EOR-CO2 sequestration projects.
