SeQuential Biofuels Opens Solar-Powered Biofuels Station

SeQuential Biofuels has opened a solar-powered retail biofuels station offering a full range of ethanol and biodiesel blends: E10, E85, B5, B20 and B100.

The station features 244 solar panels that cover the fueling islands and 4,800 plants installed in five inches of soil on the roof of the attached convenience store. The 33kW solar array will provide 30% to 50% of the electrical power that the station will require annually.

The “living roof” will help to control rainwater runoff on the site and will help cool the convenience store during the summer. Other eco-friendly design elements include stormwater detention bioswales where plants will filter pollutants from rainwater that rinses the roadways and parking areas and will clean the water before it leaves the site. SeQuential also has made a significant effort to source building materials that are made in the Pacific Northwest region.

A portion of the biodiesel dispensed at the station is received from SeQuential-Pacific Biodiesel in Salem, Oregon. SeQuential-Pacific Biodiesel is Oregon’s only ASTM-certified, commercial biodiesel production facility, producing one million gallons of biodiesel per year from used cooking oil collected throughout the Pacific Northwest and from canola oil grown in Eastern Oregon.

The land where the station is located was the site of a previous fuel station that shut down more than ten years ago. Under supervision of the former owner, the site had been contaminated by leaking gasoline tanks and pumps and the owner had abandoned it. SeQuential worked with Lane County and with the Oregon Department of Environmental Quality to clean up the previously polluted brownfield property and put it back into productive use.

Very nice.

Only question... a 33kw solar array is pretty beefy. I know it does not make power at night but one would think that would be enough for one gas station.

They would need 66kw to 100kw to go off grid? WOW. Maybe they would look at power usage a bit too.

They are in Eugene, OR, which is cloudy and rainy much of the year. So even though they are using a 33kw seutup, they likely only see full production in the summertime. Also, they are far enough north that it gets dark at about 4:30 pm in December, so that is likely also a factor....

Last, if you read elsewhere, the convienence store also houses (or has adjacent to it) some sort of bakery/coffee shop. Pumps for fuel and refrigeration units do use a lot of power.

Must be all the bright lights and signs used at night. Otherwise, I can not think of another reason.


Those HID lights for the covered fueling area are typically 1kw each, and there are quite a few, so that alone is a large chunk of power being used after dark.

What about the plants on the roof? I know this sounds naive, but don't plant roots like to grow a tear up sidewalks? How would this affect the roof?

John Ard,
It is called a green roof. For a gas station, that might be a little heavy. But then again, the solar panels are heavy too.
___The point of solar panels is:
a) reducing electric bills.
b) in case of power outage, the pumps still work during the day. If it comes with a large battery pack, or some other way to store elctricity (or even a gas/diesel generator) it might work during the night too.
