Product Description
This presentation discusses life cycle inventories of cradle-to-gate delivered natural gas fuel and cradle-to-grave natural gas fired electricity generation with a focus on greenhouse gas emissions. The study looks at eight distinct sources of natural gas and performs a number of sensitivity studies. The results show that production rate, episodic emission factors and the flaring rate have the most impact on the cradle-to-gate emissions profile, while power plant heat rate or efficiency most affects the cradle-to-grave emissions.
