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!
Sustainable Endurance at Le Mans
The race to the checkered flag at the 24 Hours of Le Mans is one of the most difficult challenges in all of motorsports. The incredible merging of skill, effort, engineering, weather and luck needed to succeed there, is mind-boggling. But now, in a world ever-mindful of environmental impacts, these racers now face another enormous challenge.
Every year in the month of June, the small town of Le Mans, France transforms into a motorsports mecca. For the 2024 edition, more than 239,000 race fans converged from all over the world, eager to cheer on their favorite teams. They stood 10-deep to watch the drivers parade through town. They flooded merchandise shops, clogged the fan zones and paddocks, filled the grandstands to capacity, and camped out to claim prime viewing spots along the 8-mile public road circuit. Through sun and rain and dark of night, this iconic 24-hour race is filled with high-speed drama, tragedy, strategy, and adrenaline. The sheer spectacle of it all is mesmerizing.
Le Mans is the ultimate durability test for driver and machine, as both must perform at their best for an entire trip around the clock. But in the light of worldwide concern for the environment, that same clock is ticking for motorsports to clean up its act.
Many outsiders view racing as a waste of resources, a frivolous pursuit of ego at the expense of eco. The old adage “win on Sunday, sell on Monday” still holds true, but the extreme conditions of competition have always served as a testing ground and accelerator for technological development, and that now includes sustainability. More than ever, that’s what drives car sales.
In fact, wide-sweeping changes are taking place in all forms of motorsport. Race organizers here and around the world have set a goal of achieving carbon neutrality by 2030, with the aim of reducing race-related emissions by 30%. The World Endurance challenge series, which includes the 24 Hours of Le Mans, now runs on 100% renewable fuel. Known as Excellium Racing 100, this biofuel is derived from grape residue. Leave it to the French to run race cars on wine!
Michelin has developed a tire composed of 71% biosourced materials, currently being tested on prototype race cars. The FIA sanctioning body issues three levels of sustainability accreditation, as a way for teams, suppliers and race venues to measure and enhance their environmental commitments. The sustainable endurance award was created in 2021 to encourage positive innovation, social engagement and low carbon impact. Since 2023, all teams racing in the 24 Hours of Le Mans are required to compete for this trophy.
Penske Porsche Racing won that honor in 2023 with their racing for charity initiative, and was again challenging in 2024, donating 750 euros for each lap completed to provide medical procedures for disadvantaged children.
The fully-electric Formula E series is maturing into a competitive and viable platform, and now even NASCAR is exploring an EV racer class. 2025 will see the debut of Extreme H, the world’s first hydrogen-fueled race series. Meanwhile, Toyota and others have announced plans to compete with hydrogen-powered cars at Le Mans as early as 2027.
And fans can get in on the green act too, earning 10% off ticket prices and other incentives by taking mass transit, bicycles or low-emission cars to the Le Mans circuit. All of these efforts will have a positive environmental impact, while ensuring the thrill of clean competition will endure for years to come.
