This would result in a reduction of carbon emissions of about 1,291 metric tons each year.
The renewable natural gas from Puget Sound Energy (PSE) will go to facilities currently using natural gas, including the top three using the most natural gas: Pier 66, Terminal 91 and maintenance facilities.
Pier 66 and Terminal 91 handle cruise ships.
Nearly halves maritime division's greenhouse gas emissions
'PSE’s renewable natural gas program will immediately cut our own maritime division greenhouse gas emissions almost in half,' Port of Seattle Commissioner Ryan Calkins said. 'That reduction helps us meet goals while implementing longer term solutions to phase out fossil fuels.'
Supply for renewable natural gas comes from a long-term contract with Klickitat Public Utility District. Methane from a Washington landfill is captured, processed into renewable natural gas and added directly into PSE’s natural gas system.
