Look into updated default emission factors about open-grid-emissions HOT 3 OPEN

The eGRID technical guide also notes that for geothermal emissions:

The three pollutants’ [CO2, SO2, NOx] emission factors, obtained from a 2007 Geothermal Energy Association environmental guide (GEA, 2007), are applied to plant net generation, and differ depending on the type of geothermal plant as identified in various reports from the Geothermal Energy Association (now known as Geothermal Rising) (GEA, 2016)

• Research whether there are more recent emission factors for these plant types than 2007
• Research whether geothermal plants can have CH4 and N2O emissions
• Can geothermal plants actually have NOx and SO2 emissions? The eGRID documentation refers to "hydrogen sulfide combustion" as the source of these emissions.

IPCC Factors come from Chapter 2: https://www.ipcc-nggip.iges.or.jp/public/2006gl/pdf/2_Volume2/V2_2_Ch2_Stationary_Combustion.pdf, Table 2.2
To convert from (kg of greenhouse gas per TJ on a Net Calorific Basis) to lb/mmbtu, you must multiply by 0.002326

SGC Synthesis Gas from Coal is only burned in a single plant: 1004. We currently use the NG rate for this, but the EIA actually says this factor should be created based on the input fuel to producing the gas.

If you look at the CEMS data for plant 1004, it has a relatively consistent co2 output of about 286.37 lbCO2/mmbtu of fuel, which suggests that this may be the appropriate factor for SGC.
