Environmental Aspects of Green Ammonia Role in Ukrainian Energy Sector

Abstract

Ammonia production using traditional Haber-Bosch technology using natural gas or coal emits large amounts of carbon dioxide and consumes a significant amount of electricity, its generation consumes a lot of fossil fuel and produces a large amount of emissions of pollutants and CO2. The transition to the production of "green" ammonia with the help of electricity from renewable energy sources and nuclear power plants will require a significant increase in their capacity. This will not only avoid CO2 emissions from NH3 production, but also avoid emissions of pollutants and greenhouse gases at thermal power plants by replacing their capacity with "green" capacity. Ammonia as a fuel has environmental advantages over traditional fuels, as it does not emit dust, sulfur dioxide, carbon monoxide and carbon dioxide. Only nitrogen oxides are formed, the emissions of which are reduced by the use of selective reduction technologies. Promising combustion of mixtures of ammonia and hydrogen. Co-combustion of coal and ammonia in existing boilers can significantly reduce emissions of pollutants and CO2. Bibl. 18, fig. 2, table. 2.

Creating the Holdings of Nuclear Power Plants and/or Renewable Energy Sources with Ammonia Production Plants on the Base of Circular Economy

“…When calculating the production function of a thermal power plant under the conditions of its consumption of ammonium fuel, a 7% fuel saving was adopted while maintaining the volume of released electricity due to the elimination of means of dedusting and desulfurization of flue gas [21]. The points in Figure 3 show the current annual data on the operation of the thermal power plant in terms of electricity generation and fuel consumption; the curve contouring the specified points is actually a production function.…”
