While energy storage is key to increasing the penetration of variable renewables, the near-term effects of storage on greenhouse gas emissions are uncertain. Several studies have shown that storage operation ca. ••The regional impacts of storage operation on CO2 emissions are. a Regression CoefficientsC Consumption-based CO2 EmissionsDn. Electricity storage is key to enabling the grid integration of non-dispatchable low carbon electricity generation at large scales. Storage costs have dropped considerably ove. To provide context, we begin our analysis by characterising emissions from the whole GB national electricity system, applying existing approaches from the literature to calculate margin. 3.1. AssumptionsAs our intention is to provide the first evaluation of materiality, we make simplifying assumptions. The most significant is that. 4.1. Evaluating the regional MEFsFig. 7 shows MEFs calculated with both the enhanced linear regression and simple linear regression approaches presented in Section 3.2, for t.
