“…Third, to estimate BC emissions based on PM 2.5 emissions, the PM speciation source profiles from U.S. EPA's SPECIATE database (http://www.epa.gov/ttn/chief/software/speciate/) are applied. According to Grammelis et al [], coal‐fired power plants in Russia are mainly equipped with electrostatic precipitators (ESP), scrubbers, and combinations of those equipments. By selecting the emission measurements of coal‐fired power plants equipped with ESP and scrubbers, a total of 32 profiles (3 profiles are excluded as outliers) from the SPECIATE database fit our requirements.…”

Russian anthropogenic black carbon: Emission reconstruction and Arctic black carbon simulation

Development of reliable source emission inventories is particularly needed to advance the understanding of the origin of Arctic haze using chemical transport modeling. This study develops a regional anthropogenic black carbon (BC) emission inventory for the Russian Federation, the largest country by land area in the Arctic Council. Activity data from combination of local Russia information and international resources, emission factors based on either Russian documents or adjusted values for local conditions, and other emission source data are used to approximate the BC emissions. Emissions are gridded at a resolution of 0.1° × 0.1° and developed into a monthly temporal profile. Total anthropogenic BC emission of Russia in 2010 is estimated to be around 224 Gg. Gas flaring, a commonly ignored black carbon source, contributes a significant fraction of 36.2% to Russia's total anthropogenic BC emissions. Other sectors, i.e., residential, transportation, industry, and power plants, contribute 25.0%, 20.3%, 13.1%, and 5.4%, respectively. Three major BC hot spot regions are identified: the European part of Russia, the southern central part of Russia where human population densities are relatively high, and the Urals Federal District where Russia's major oil and gas fields are located but with sparse human population. BC simulations are conducted using the hemispheric version of Community Multi‐scale Air Quality Model with emission inputs from a global emission database EDGAR (Emissions Database for Global Atmospheric Research)‐HTAPv2 (Hemispheric Transport of Air Pollution) and EDGAR‐HTAPv2 with its Russian part replaced by the newly developed Russian BC emissions, respectively. The simulation using the new Russian BC emission inventory could improve 30–65% of absorption aerosol optical depth measured at the AERONET sites in Russia throughout the whole year as compared to that using the default HTAPv2 emissions. At the four ground monitoring sites (Zeppelin, Barrow, Alert, and Tiksi) in the Arctic Circle, surface BC simulations are improved the most during the Arctic haze periods (October–March). The poor performance of Arctic BC simulations in previous studies may be partly ascribed to the Russian BC emissions built on out‐of‐date and/or missing information, which could result in biases to both emission rates and the spatial distribution of emissions. This study highlights that the impact of Russian emissions on the Arctic haze has likely been underestimated, and its role in the Arctic climate system needs to be reassessed. The Russian black carbon emission source data generated in this study can be obtained via http://abci.ornl.gov/download.shtml or http://acs.engr.utk.edu/Data.php.

“…On the contrary to radical solutions such as rapid shut down of coal power plants which is associated with immense costs [12], rehabilitation and repowering of the existing units to prolong their service, increase their efficiency and decrease the pollutants emissions appears more feasible [13,14]. Many countries that relied heavily on coal power plants, such as Russia [15], Poland [16,17], Czechia and Slovakia [18,19] or Balkan countries [20,21], chose to follow this path. The power production sector and the associated renovation activities receive a lot of attention both from governments and researchers [22,23].…”

Repowering of industrial combined heat and power units allows reducing industrial greenhouse gases emissions. An existing industrial unit served as model in the gas turbines-based repowering study, aiming at fuel consumption and carbon dioxide emissions reduction. Following unit's model setup and verification, two conservative repowering options (hot windbox and separate gas turbine + heat recovery steam generator) were assessed from economic, energetic, and environmental point of view, including seasonal impact. Hot windbox option leads to annual power production increase by 14.3% (72.8 GWh/year), accompanied by carbon dioxide emissions reduction by 3.9 % (29.5 ktons/year) compared to the base case. The second option delivered more significant power production increase (+261.9 to +298.6 GWh/year) with CO 2 emissions, either slightly higher (+1.5 %) or modestly lower (-4.0%), than in base case depending on heat recovery efficiency from gas turbine exhaust. Both options show feasible economics with simple payback period as low as four years under favorable combination of fuel and electricity prices and CO 2 costs. External CO 2 emissions change due to the change in unit's power production further reduces the total CO 2 emissions, strongly depending on the applied power production emission factor.

“…While natural gas ranks first in primary energy consumption, oil follows it with a share of 19%. Coal also plays a dominant role in the energy production mix in Russia (Grammelis et al, 2006). Coal use, and therefore investment, is expected to increase significantly in the Russian Federation in the next few decades.…”

Coal, the fundamental element of the industrial revolution, is widely used for energy production in many countries. The use of coal in energy production continues in countries that have coal reserves, as well as in countries that are rapidly transitioning to renewable energy production. The aim of this study is to investigate the causal relationship between coal production and general energy consumption in Russia and Türkiye, which are among the countries that consume heavy coal. In the article, the relationship between the variables in these countries was tested with Granger causality analysis. According to the results of the analysis, it was determined that there was a one-sided causality relationship from coal production to energy consumption in Russia. When the findings of the study were examined from the perspective of Türkiye, no causality relationship was found between the variables.
