9. RENEWABLE Natural gas REMOVE GHGs WHAT’S POSSIBLE
POWER 2-3 million homes
WHAT’S POSSIBLE
REPLACE 75% of all diesel
used by CA vehicles
When used for transportation, Biogas from food and green waste can actually
REMOVE GHGs
from the atmosphere
Convert waste from dairies, farms and landfills
into biogas
using anaerobic digestion
extract the methane
put in the pipeline for future use

10. POWER-TO-GAS Long-Term Energy Storage
carbon captured from factories and plants
excess
renewable energy
water
electrolysis
which splits
the molecule
hydrogen & carbon combine through methanation
methane can be stored
in the pipeline
for future use
hydrogen can also
be stored directly
in the pipeline
