Problem

Problem

  • Carbon dioxide (CO2), emitted largely from the burning of fossil fuels, is the main agent causing global warming.

  • According to the Kyoto protocol signed by the Baltic countries in 2002, the level of air-polluting greenhouse gases should be reduced by 8% compared to the 1990 level.

  • Reduction of carbon dioxide could be reached using different measures including :

  • the improvement of energy efficiency and demand,

  • use of renewable energy sources

  • capture and geological storage of CO2 (CCS).

  • In 2006 the Baltic States, together with other European countries, started an inventory of major CO2 emission sources, assessment of CO2 geological storage capacity and dissemination of information about CO2 capture and storage in the frame of

  • EU GEOCAPACITY (25 countries) project and

  • CO2NETEAST (8 countries) project

    supported by EU Commission Framework

    Programme 6.

  • Both project were organized by GEO ENeRG –

    European Network for research in GEOENERGY

    .


Geological storage of industrial co 2 emissions in the baltic states problems and prospects

  • Compared to the other European countries, the Baltic States are in a rather unique geological setting. Most of the countries contain a number of small basins that have different characteristics.

  • Lithuania, Latvia and Estonia are situated within one common Baltic sedimentary basin. Therefore, a joint study is required for the assessment of the geological sinks.

  • The source types and emission amounts differ considerably in the Baltic countries, depending on the socio-economic conditions.

  • Geological conditions are also different, as these countries represent different parts of the Baltic basin.

  • 6.6 tonnes in Europe and Central Asia (data of the World Bank).


Baltic industrial emmisions

Baltic industrial emmisions

  • 24 big emissions (+ 3 in Lithuania and +2 in Estonia close to 100kt)

  • 2005:

  • 11,5 Mt in Estonia

  • 5,6 Mt in Lithuania

  • 1,9 Mt of CO2 in Latvia

Geological storage of industrial co 2 emissions in the baltic states problems and prospects

  • In Lithuania -Latvian–Lithuanian border

  • (Mazeikiai–Akmene area),

  • oil-processing factory - 1870 Kt

  • EPS - 273 Kt of CO2

  • In Latvia, - western part of the country.

  • Liepaja metallurgical enterprise - 366 Kt of CO2,

  • Liepaja EPS - 108 Kt of CO2

  • cement factory in Broceni - 285 Kt of CO2.

  • Three EPSs emit 619, 381 and 136 Kt of CO2 in the Riga area

  • Cement production - northern Lithuania.

  • The Naujoji Akmene Boiling Plant for Cement Plant produces 783 Kt of CO2.

  • southeastern Lithuania - EPS in Elektrenai (715 Kt of CO2),

  • two EPSs in Vilnius (701 and 260 Kt of CO2)


Only industrial sources 100 kt co 2 will be captured

Only industrial sources >100 kt CO2will be captured

  • After capture, CO2 can be either stored or re-used.

  • CO2 can be stored in geologic formations including

  • depleted oil and gas reservoirs

  • deep saline aquifers and (salinity >100g/l)

  • unminable coal seams and abandoned coal mines

  • CO2 can also be fixated in the form of minerals.

Conclusions

CONCLUSIONS

  • The Middle Cambrian siliciclastic reservoirs are considered prospective formations for CO2 trapping in the Baltic region.

  • The structural trapping is an option in Latvia having number of large anticlinal structures with a total potential of more than 500 Mt in the Middle Cambrian aquifer.

  • The shallow sedimentary basin (100–500 m), small depth of the closed oil-shale mines (60–65 m) and use of all aquifers for drinking water supply make geological conditions in Estonia unfavourable for CO2 geological sequestration.

  • Lithuania has a potential for CO2 solubility storage in Devonian and Middle Cambrian saline aquifers, but without possibilities for structural trapping (Šliaupa et al. 2005).


Conclusions1

CONCLUSIONS

  • The Inčukalns underground gas storage operating in Latvia, which is used for the supply of natural gas to Latvia, Estonia and Lithuania, is a positive example of collaboration in the region.

  • The existing infrastructure of pipelines, already connecting the large Baltic CO2 sources with Latvian prospective anticlinal structures, provides a possibility of reducing the price of the future CO2 pipelines and a good prospect for geological storage of the substantial Baltic industrial CO2 emissions in the most favourable geological conditions available in Latvia.


Other options in estonia

Other options in Estonia

  • Eesti Energia is utilizing a process for neutralizing alkaline ash transport water through a reaction with liquid CO2.

  • In June of this year Eesti Energia launched a research project to study the potential for CO2 capture by the alkaline ash that is generated as a residue during power generation. This solution will be an alternative to the many developing CO2 sequestration technologies.
