CO2 EMMISSIONS FROM CHARGING USING THE GRID LEAD-ACID BATTERY
LITHIUM ION
FUEL CELL
Carbon dioxide produced per year from natural gas lbs/year lbs/year 0 lbs/year
Carbon dioxide produced per year from coal lbs/year lbs/year 0 lbs/year
Carbon dioxide produced per year from petroleum lbs/year lbs/year 0 lbs/year
Total (SEC has proposed GHG emmissions disclosures) lbs/year
Guidance:
We assumed that the consumption of kWh is the same as lead-acid. Reduction comes from charger and coulombic efficiencies.
lbs/year
Guidance:
Green hydrogen is made from renewable electricity and water. The H2 is produced by splitting water into its molecular components. When hydrogen is consumed in a fuel cell it reforms as water, producing electricity, and heat. If liquid green hydrogen is transported using green transportation the GHG is near or at zero. 0
