Microscale air quality impacts of distributed power generation facilities

Abstract

Plausible scenarios of distributed fossil generation consistent with the electricity grid's transformation to a more flexible and modernized system suggest that a substantial amount of deployment would be required to significantly affect air quality on a localized scale. In particular, natural gas turbines typically used in distributed generation may have minor effects. Large banks of diesel backup generators such as those used by data centers, on the other hand, may require pollution controls or conversion to natural gas-fired reciprocal internal combustion engines to decrease nitrogen dioxide pollution.

The assessment of two different pollutants dispersion from a coal-fired power plant for various thermal regimes

“…Park et al [47] continued consideration of the use of electron beam technology (EB) used to simultaneously remove SO 2 and NO x from the combustion components of flue gases emitted from a power plant. Emissions primarily depend on the type of fuel burned at power plants: solid fuel leads to a high concentration of emissions [41,48,60], another type of power plant fuel is natural gas, the emissions effects of which were investigated by [10,23,46] compared different emission generation scenarios (point and mobile sources) from a power plant, using a 3D microscale model of chemical transport, as the distribution of pollutants studied in the mesome scale models does not allow to solve high gradients of air pollution. The use of parameterized microscale models such as OSPM [6], SIRANE [57] or ADMS-URBAN [52] is widely used for air quality modeling.…”

Numerical modelling of a passive scalar transport from thermal power plants to air environment

“…Barbero et al 28 modelled dispersion of particles near a NPP in emergency case. Particle dispersion and deposition on buildings in urban environments were investigated by Gousseau et al 29 and Kumar et al 30 Olaguer et al 31 simulated various scenarios for the energy facilities' operation (different capacities and regimes). They also investigated the distribution of particles and various gases.…”
