Geothermal energy of Slovakia - CO₂ emissions reduction contribution potential (background study for conservative and non-conservative approach)

摘要

Total geothermal energy potential is estimated for 209 714 TJ per year or 6 650 MWth. Natural conditions define a use of thermalwaters for heat generation only. Accepting proportion of real achievable output of geothermal projects in the non-conservative scenarioat a rate of 1 861 MWth or 13 440 TJ per year, yearly carbon dioxide savings are up to reach 0,357 MtCO2.yr-1 or 12,5 of cumulativeMtCO2 in 35 years. By a contrast, introduction of conservative approach points to increase in a geothermal heat production from 145 to243 TJ per period or 6 944 TJ of cumulative 35 years production, with a real outcome of 0,45 MtCO2 cumulative carbon dioxidesavings, corresponding to yearly real savings from 9,4 .10-3 to 15,8 .10-3 MtCO2.
