Blythewood High School Making Biodiesel
With so much focus on the development of electric cars these days, it’s easy to overlook some of the tried and true clean fuels that are still making a positive impact on our environment; but, we recently visited a group of alt-fuel all-stars who are fueling their future with biodiesel!
Blythewood high school serves about 2000 students in rural Richland county, South Carolina. Typical of the area, it offers a few vocational classes in agriculture, construction and mechanics, but this chemistry course is anything but typical. These students are learning how to make biodiesel from donated used cooking oil.
This unique curriculum is the brainchild of Will Epps, a science teacher here who identified a need in the local job market and sought a solution.
WILL EPPS: In the summers I work as a chemist at Westinghouse and what I noticed is that, in the lab space, there was a lot of turnover with technicians. And I was, you know, as a chemistry teacher, and kind of being one foot in both worlds, it kind of dawned on me and I was thinking well, why can’t we train high school kids to have this job? Noticing that what we’re doing in a chemistry class, they need a little bit extra to be successful in that environment.
JOHN DAVIS: Pairing that idea with some basic equipment found at the school, Will got the biodiesel program up and running a couple of years ago.
It’s been expanding ever since and recently earned a grant from the South Carolina Energy Office through the US Department of Energy’s state energy program, with additional help from Palmetto Clean Fuels, South Carolina’s clean cities coalition; but it’s really Will’s infectious enthusiasm that draws students to the class.
AVA: I wanted to get involved in this program because I had, uh, Mr. Epps as a teacher before, and he was a really great teacher, and he convinced me that I was good at science and that I could continue being in science classes because I was previously a little insecure about my abilities with science.
CAMDEN: and also, I like doing the work. The work’s pretty-- it’s complex, but easy at the same time. It gets your brain, you know, pumping.
TESSA: And, it being more, like, out there and being more, like, project-based instead of just like papers and stuff, I’m like “that could be an interesting class to go into.”
JOHN DAVIS: In this lab, students not only learn the basics of chemical reactions, but also gain over 100 hours of laboratory experience; enough to help them qualify for chemical engineering and other lab internships at local companies.
WILL EPPS: It’s a great product. You know, it’s simple enough for students to understand; you know, we mix two things together and we get a product that separates out, and then we have a lot of analytical chemistry techniques that we need to proof that the fuel is good enough quality to go in an engine. So, it kind of fits both worlds, um, and it’s really nice to be able to take a waste product and change it into something that we can use again.
JOHN DAVIS: The student-made fuel is currently being tested in the school’s tractors and by diesel truck owners in the local community with great results, but the ultimate goal is to top off their own buses with a cleaner blend of B10 or B20 biodiesel made right at the school.
WILL EPPS: So the plan right now, and where we’re at, is that we can make 40 gallons of B100 in a week, and so the goal is to maybe double or triple that capacity over the next couple of years. And, you know, really our product is the biodiesel, but really the product is our students, and getting them into the workforce and being successful.
AYDEN: Well, now I’m really interested in chemistry.
KATRELL: I’m happy we can, you know-- we’re doing at least a little something to help.
TY: I know where we’re going right now is not the best, but if we can do any amount to help it, then that’s what I’m all for.
TYLER: It’s just a really cool thing to be a part of; saying “hey, you see that bus driving? I helped fuel that.”
JOHN DAVIS: Gaining a healthy respect for the environment, to go along with invaluable hands-on experience, these students are literally fueling a clean driving future for all of us!
Waste Not Want Not
JOHN DAVIS: The concept of renewable fuels made from non-petroleum sources has a long history. Indeed, over the last four decades, we’ve seen how renewable fuels have been used with great success as sustainable alternatives to traditional gasoline and diesel. So, we thought we’d check out three examples where fast responses rely on reliable fuels, and see how green solutions are leading the way forward!
Our first stop is Vancouver, Washington, where the city’s fire department has made the switch to renewable diesel for its 27 fire trucks, engines and EMS squads. Also called RD or R99, renewable diesel is not the same as biodiesel. It is refined from plant oils and animal fats to become chemically identical to conventional diesel, which biodiesel is not. R99 performs better in cold weather and can be used without modification in any diesel vehicle.
The process of burning carbon soot out of a conventional diesel’s exhaust particulate filter, known as regen, can take a truck out of service for several hours over the course of a week. Using R99 instead, less soot builds up, increasing the regen intervals and requiring a less intense regen procedure.
The Vancouver Fire Department responds to 51,000 emergency calls each year, so every minute of downtime in the shop can be the difference between life and death.
CHUCK WINKLER: These vehicles have to work 100% of the time, all the time. So, reliability is our number one… Safety and reliability is our number one goal here, and R99 has really helped with that 100% reliability.
JOHN DAVIS: Then there is UPSA, one of world’s largest delivery fleets with 125,000 vehicles. UPS obtains nearly 40% of their transportation fuel from low-carbon sources, and has driven over 4 billion miles on alternative fuels. They are also the largest consumer of renewable natural gas in the transportation industry.
AL MURAT: While electric cars, electric vehicles, Es are going to play an important role, right now CNG and RNG is one of the important bridge points to getting there. So, rather than wait for those alternatives to grow in technology, we’re leveraging RNG right now as one of the best solutions.
JOHN DAVIS: RNG, also known as biomethane, is derived from decomposing organic matter at landfills, wastewater treatment plants, livestock farms, and food production facilities. RNG is interchangeable with conventional natural gas and can be used in existing pipelines.
This renewable natural gas fueling station at UPS’ eastern zone hub in Pennsylvania, is the largest in the UPS network. It services 220 tractors and 150 delivery vehicles, displacing 8 million gallons of diesel fuel per year. Renewable natural gas literally turns waste into clean energy, and is helping big brown deliver on its longtime commitment to go green.
Whenever a green flag drops, the extreme conditions of motorsports competition have long served as a testing ground and accelerator for technological development, and that now includes sustainability. Race organizers around the world have set a goal of achieving carbon neutrality by 2030, and aim to reduce race-related emissions by 30%. The world endurance challenge series, which includes the 24 Hours of Le Mans, now runs on a 100% renewable fuel derived from grape residue.
In a sport where lightning fast reflexes and instant throttle response can mean the difference between first place and also ran, a stable, power-dense fuel is a must, and you gotta admit, running race cars on wine is pretty dang cool!
These three sustainable petroleum substitutes are all winning formulas, ones we will be keeping an eye on.
