Life cycle greenhouse gas emissions of Marcellus shale gas
Mohan Jiang,W. Michael Griffin,Chris Hendrickson,Paulina Jaramillo,Jeanne M. VanBriesen,Aranya Venkatesh +5 more
TL;DR: In this article, the life cycle greenhouse gas (GHG) emissions from the production of Marcellus shale natural gas and compared its emissions with national average US natural gas emissions produced in the year 2008.

Deterministic electric power infrastructure planning: Mixed-integer programming model and nested decomposition algorithm
Cristiana L. Lara,Dharik S. Mallapragada,Dimitri J. Papageorgiou,Aranya Venkatesh,Ignacio E. Grossmann +4 more
TL;DR: This paper proposes a decomposition algorithm based on Nested Benders Decomposition for multi-period MILP problems to allow the solution of larger instances and adapts previous nested Benders methods by handling integer and continuous state variables, although at the expense of losing its finite convergence property.

Uncertainty in life cycle greenhouse gas emissions from United States natural gas end-uses and its effects on policy.
TL;DR: The use of natural gas for power generation instead of coal was found to have the highest and most likely emissions reductions, while there is a 10-35% probability of the emissions from natural gas being higher than the incumbent if it were used as a transportation fuel.

Uncertainty analysis of life cycle greenhouse gas emissions from petroleum-based fuels and impacts on low carbon fuel policies.
TL;DR: The uncertainty range in life cycle GHG emissions from gasoline was shown to be 13%-higher than the typical 10% minimum emissions reductions targets specified by low carbon fuel policies.

Implications of changing natural gas prices in the United States electricity sector for SO2, NOX and life cycle GHG emissions
TL;DR: In this article, simplified economic dispatch models are used to determine how natural gas utilization will increase in the short-term in response to changes in natural gas prices in three US grid regions.
