• Transportation sector produces 41.9 MMtCO2e GHG emissions (WA, 2011).

• Landfills, WWTPs, dairies/feedlots 6.7 MMtCO2e.

• Total GHG emissions 91.7 MMtCO2e.

• Post-Trans Alta (2020), 78.9 MMtCO2e WA total.

• Transportation sector: 53% of 2020 total emissions.


11

• The 10 largest landfills, waste water treatment plants and dairy/feedlots produce 368,175 DGE/day of useable bio-methane (WA, 2013).

• On-road diesel use 1,799,671 gal/day (WA, 2014).

• Economically recoverable: 20% total diesel use.


12

• Flaring/CoGen/Process Heat: Least worst options.

• Electric Power: Uneconomic (2.3¢ kW-hr in WA).

• Pipeline Injection: $750K/mile (Yakima county).

• Gas Compression: High capital costs per capacity.

• Renewable LNG (RLNG): Proper equipment key.


13

Technical Solution:

• 𝜇LNG Gas Cooler 5m3/day.

• Right-sized gas clean-up.

• Primary focus is on efficiency (fewest kw-hours/gallon).

• No synthetic refrigerants.

• Recycle CO2 (greenhouses)

Carbon Negative RLNG:

• Displace diesel.

• Mitigate biogas emissions.
