Port of Tacoma turns to renewable diesel

The Port of Tacoma has begun using a renewable diesel called R99, a drop-in fuel that can run in any diesel engine without equipment retrofits.

R99, which stands for 99 per cent renewable, is produced using a different technique than biodiesel, but it still contains the same raw ingredients, such as discarded cooking oil and animal fats.

The port noted that renewable diesel can be blended at any amount because it is produced in refineries to be chemically identical to petroleum diesel.

In contrast to conventional diesel, renewable diesel resembles water. Above all, it burns considerably cleaner.

Rose Arsers, Environmental Project Manager at the Port of Tacoma and NWSA, said: “Depending on the fuel source, it can offer a 60 to 75 per cent reduction in lifecycle GHG emissions and about a 20 to 30 per cent reduction in particulate matter.”

In July 2023, Port of Tacoma Commissioners voted to reduce GHG emissions under the port’s direct control to net zero by 2040, accelerating the target by a decade. 

The port and NWSA are reportedly pushing for greener short-haul trucks, establishing shore power at more container terminals, and introducing electric cars and yard trucks.

Port of Tacoma Commission President, Kristin Ang, stated: “We are making the major investments today so that when we have this press conference in 10 years, you will see the results.”

In January, the 5G Open Innovation Lab (5G OI Lab), EDGE Cluster, Washington Maritime Blue, the City of Tacoma, and partners launched a 5G Private Network in Tacoma Tideflats to service five enterprise clients.
