Figure Lengend Snippet: Midpoint environmental impact indicators for CCGT with CCS compared to wind and photovoltaic generation. NG supply scenarios: global average supply (GA), BC average production in 2020 (BC), and BC Montney production with electric drive compressors and 2030 fugitive methane emission reduction target achieved (M3). Results for wind and photovoltaic shown for BC. Results in each environmental impact category normalized to the maximum case in that category. Environmental impact categories: stratospheric ozone depletion (SOD), ionizing radiation (IR), ozone formation–human health (OF-HH), fine particulate matter, ozone formation–terrestrial ecosystems (OF-TEs), terrestrial acidification (TA), freshwater eutrophication (FW-EU), marine eutrophication (M-EU), terrestrial ecotoxicity (T-ECO), freshwater ecotoxicity (FW-ECO), marine ecotoxicity (M-ECO), human carcinogenic toxicity (HCT), human noncarcinogenic toxicity (HNCT), LU, mineral resource scarcity (MRS), fossil resource scarcity (FRS), and water consumption (WC).
Article Snippet: The values used in this study from Ecoinvent background inventories for wind (13–18 kgCO 2 e/MWh) and photovoltaic electricity generation (59–77 kgCO 2 e/MWh) are within the corresponding ranges of published values.
