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!
American Center for Mobility
In the history of car development, proving grounds have played a crucial role in allowing carmakers to validate a car’s functionality, performance, and durability. But as we move into a new era of electrification, AI and self-driving cars, the role of the proving ground is evolving as well. Come along as we peek behind the privacy fence at one test track that’s building on its past, to keep pace with the future.
The American Center for Mobility is located adjacent to Ford’s historic B-24 bomber factory at Willow Run airport near Detroit, Michigan and on the former site of GM’s Ypsilanti transmission plant. The only remnants from that now are a few security posts and wide expanses of cracked pavement, but these reminders of bygone industry are exactly what’s helping today’s engineers perfect the cars and trucks of tomorrow.
Like a typical proving ground, the 500-acre facility includes a 2-mile highway loop with exit ramps and road signage, a 700-foot tunnel, simulated urban areas, and six-lane intersections. It’s not a pristine environment, with bumps, lumps and weeds everywhere, but that’s just how ACM’s clients want it.
REUBEN SARKAR: But you know, cracked pavement, potholes, faded lane lines. In some cases, you want to leave those as they are because that’s what people encounter in the real world.
JOHN DAVIS: And as we soon found out, the testing that takes place here is far from typical.
REUBEN SARKAR: A traditional proving ground is focused on testing the mechanical paces of a vehicle. So, you think about ride and handling, NVH, durability. Ours is designed to test the sensing and situational awareness of a vehicle. What can it see and sense, and how does it make decisions, right, in terms of a computer replacing a human driver, so it’s less tuned towards, you know, like a high-speed oval, nice perfectly paved track. It’s really meant to throw challenges at the vehicle sensor.
JOHN DAVIS: Another ACM specialty is found inside the EV base camp, a unique test facility for electric vehicle charging equipment, set up through a grant from the federal government’s joint office of energy and transportation. The goal here is to ensure that every EV charger works every time, with every kind of car.
REUBEN SARKAR: But it’s really a place that you can put a diversity of different DC fast chargers and then have a place where the autos and others can come and test against those different fast chargers. So, a place that you can check whether the car software talks to the charger software to make sure that they’re interoperable, so even though you may have a standard, how people code on the vehicle side, how people code on the charger side, and then all the variables that come into play in the real world, you know, when the charging happens, can cause interoperability issues.
JOHN DAVIS: Making this all possible is another leftover from the GM transmission plant – an on-site electric substation. And in the world of EV charger testing, power is the key to everything.
REUBEN SARKAR: Why the substation is important to us is, we own the power house that’s on the end of it, makes us the utility on property, There’s the ability to expand the capacity of that substation to 90 megawatts. And you’ll find that a lot of people just don’t have a lot of idle grid capacity that’s sitting around, right. Even at large automotive companies, we’ve had some of them tell us “hey, we’re maxed out on power.”
That power station will allow us to do extreme fast charging, to be able to host very large testing events, testing symposiums, where there are, you know, 30 cars being tested at once against 30 different chargers.
JOHN DAVIS: Every new automotive technology needs to be tested and perfected before hitting the road for real. The research and validation being done here and now at the American Center for Mobility is enabling a safe and efficient driving future for us all.
