CO2Emissions Inventory and Diminishing Perspectives
Oil shaleIn 1999, share in electricity generating 92% As a fuel it is characterized by - a high ash content (45-50%), - moderate moisture(11-13%) and sulphur contents (1.4-1.8%)- a low netcaloric value (8.5-9 MJ). The production of oil shale peaked in 1980 and fell by 8 million tons from1980 to 1990.
Strategy 1 – generalIn order to achieve improvements in air quality, it is necessary:- to support development of less polluting types and means oftransport- to ensure the importation of high-quality engine fuel - to stimulate the consumption of cleaner fuels- to impose restrictions established by international conventionson the use of ozone depleting substances and in ordertoachieve - reduction of emissions of VOC and heavy metals - reduction of emission of sulphur and nitrogencompounds -stabilization and reduction of emissions of GHG(CO2, CH4, CxHy).
The projections of the GHG emissions were calculated on the basis of general trendsof the development of national economy, energy demandand supply in Estonia.
The results of the inventory of GHGshow that an approximate total of 76% of all GHG emissions consist of CO2, with combustion processes being thelargest source (approx. 98% of all CO2 emissions).
For this reason, the main attention was directed to the projection for CO2 emissions from combustion processes.
Theremaining 24% of all GHG emissions consist of methane(21%) and nitrous oxide (3%). Here the uncertainties aregreater.
Complicated task is to compile scenarios for the GHG sink, the more so as we have not scientifically supported calculations for biogeochemical cycles ofCO2 in terrestrial ecosystems for Estonia.
ConclusionsIn the Republic of Estonia the legislation, policy and measures for mitigation of the atmospheric emissions of GHG-s including CO2 have been elaborated and enforcedNo measures focused on the capture and storage of CO2 have not been foreseen in the state-level plansThe basic and applied research for CO2 mineralisation in the energy sector have been initiated by TTU under support of ESF and SC Narva Elektrijaamad
