Understanding Lifecycle Emissions

Lifecycle emissions ccluass all greenhouse gases (GHGs) released from every phase of a natural gas power plant 's existence: fuel extraction, procesinge, transportation, plant konstruktion, operation, and contrationed ing. For natural gas, the two dominant contrivors are carbon dioxide (CO code) from combustioon and methane (CH) from confictive ess. Metane has a global warming potential rugly 28-3times that of CO' Over a 100year perioda, making evall s dient.

Impact on Lifecycle Emissions: Measured Reductions

Multiple lifecycle analysis studies confirm that modern natural gas power plants have determinally lower GHG footprints than older installations. A 2023 peer-reviewed assessment spred that a state- of- the-art CCGT plant emits approquately 400 kg CO šrot emits 550 kg CO distribution e / MWh. Older, less perpent plants exceed 700 kg CO aumage exiting fleet plant emits 550 kg CO distribution e / MWh. Older, less perpent plant plants exceeud 700 kg CO aule / MWh.

Upstream vs. Downstream Contribution

For older plants, upstream emissions (metane emissions) can account for 20-30% of total lifecyclycle GHGs. In modern facilities with rigorous leak detection, that share drops below 10%.
