Offering clean fuels to Washington state’s busiest economic center, Propel is launching downtown Seattle’s first renewable fuel station, scheduled to open June 28th. The 9,000-square-foot location conveniently resides on the I5 Mercer Exit corridor, one block north of Mercer Ave, on Westlake and Valley, in Seattle’s South Lake Union neighborhood. The site is easy access with turn lanes from all directions.
Uniquely Seattle, the site was conceived, developed and built with homegrown talent. Unlike similar sites in other states, Propel received no direct or indirect financial incentives from Seattle, King County or Washington State.

Propel’s South Lake Union station is environmentally sensitive in design, construction and operation.

1. Canopy and Cistern
The station’s canopy is designed to conserve water and reduce storm runoff into Lake Union. Rainwater is collected in a cistern neatly integrated into the canopy’s western column. This cistern provides a water source for foliage, while irrigating the feedstock planters with excess water via an underground pipe. In addition, the station’s canopy was constructed utilizing aluminum composite derived from 95% recycled materials. The canopy is also equipped with energy conserving LED lights with photocells that provide illumination only as needed.
2. Landscape Green Roof Technology
The station’s garden landscape uses resource-conserving green roof technology to collect excess water from the canopy and cistern. Constructed with 100% recycled materials, the system actively stores water irrigating the landscape as needed and reducing dependence on the city’s water supply. Collecting and filtering water with green roof technology helps prevent the spread of pollution into Seattle’s groundwater and into Lake Union. The resulting runoff is clean filtered water.
3. Feedstock Planters
These unique feedstock planters grow plants used in the domestic production of biodiesel. The clean fuel is derived from renewable resources like camelina, sunflower, soy and canola, examples of which can be found in the planters. Biodiesel is also produced from waste products including recycled restaurant grease and animal fats. Biodiesel is refined to be used any diesel vehicle with no conversion necessary.
4. Clean Fuel
Two 5,000 gallon above ground tanks are constructed with industry leading safety and environmental standards. To guarantee a safe fueling environment the tanks are impact and ballistics proof, with advanced break away shut-off & emergency shut-off.
