Inspiring the Next Generation of Scientists and Engineers—As We Were Inspired

Ten-year-old Leo worked in the Education Center at the National Renewable Energy Laboratory (NREL), fitting together snap-on electrical circuits. The boy from a Denver community center was enthralled by the sheer joy of adding buzzers, lights, and switches to the device. Sitting at a desk nearby, Rhielle carefully colored a drawing of a solar panel. “I want to be everything: a singer, waitress, scientist, baker—because baking is a science,” the eight-year-old explained. Everywhere, the room buzzed with energy, as 16 grade schoolers performed experiments and talked to volunteer researchers as part of a science, technology, engineering, and math (STEM) outreach connecting NREL with our local community.

It reminded me of my own start on the pathway of scientific discovery. As a high school student in Regensburg, Germany, I wondered about this exotic world of test tubes and microscopes—and so visited the office of a distinguished biologist in my hometown university. I asked if he would talk to me—but he was busy at the moment. Instead, this scientist invited me into his laboratory, where I saw first-hand some of his experiments. Later, we chatted and he gave me a basic college text.

He continued to follow me, and mentored me throughout my science studies. I’ve never forgotten that lesson about the importance of sharing science with younger minds. That is why I’m so enthusiastic about STEM learning, and support it passionately at NREL. Whenever we can engage younger students—especially those who may not have had a chance to consider science and engineering as careers—we are building our future.

Throughout the year, NREL actively engages in a range of STEM events. Last May, we held NREL’s 27th annual Junior Solar Sprint and Lithium-Ion (Li-ion) Battery Car Competitions on campus, attracting 53 teams from 18 Colorado middle schools. Maybe you’ve been to something like this. Some cars scoot, some fizzle—yet regardless of the finish, everyone gains hands-on experience. Likewise, we co-sponsored the 27th Colorado Science Bowl, giving kids a chance to test their knowledge against other aspiring young researchers. This year the Lambkins from Ft. Collins roared to victory, correctly answering a range of questions across the sciences. We were part of the first Energy Day Colorado this fall, giving academic awards to promising scholars.

Whenever we can, we try to open our doors to prospects. Hannah, a high school sophomore from Boulder, won an NREL-sponsored award at the Colorado Science and Engineering Fair. Sure, she’d already gotten a plaque made from a recycled solar panel and a stipend of $100 for a building cooling project—but we wanted to give her something more. So we arranged a campus tour so that she could talk to researchers in her field. She chatted happily, and afterwards declared, “This place is cool.” Although she has a ways to go, she was clear: because both science and NREL are now positively linked in her mind, she hopes to one day work at the lab. Now that would be cool.

Of course, we won’t know for years whether Hannah will come here, chose another national laboratory, or find a different path. Likewise, we can’t foresee whether Leo will become an electrical engineer or Rhielle seek a career as a chemist. But we do know that 3,688 students who have visited NREL this year, or gone to competitions we’ve run, have all gained exposure to STEM activities. We can’t tell immediately how much impact these encounters have had—although the smiles of students tell us a lot—but speaking from personal experience, we should be confident that this type of inspiration can last a lifetime and will build our future.

New Initiatives Will Use Supercomputers to Improve Transportation Energy Efficiency

DOE’s Vehicle Technologies Office commits $2.5M in FY2018 funds to Big Data and High Performance Computing Initiatives.

Did you know, the Department of Energy’s National Laboratories are home to 32 of the fastest supercomputers on Earth? Scientists and researchers at the national labs use these supercomputers to accelerate research by creating models from complex data sets. Now, two new Vehicle Technologies Office (VTO) initiatives - High Performance Computing for Mobility (HPC4Mobility) and Big Data Solutions for Mobility – will utilize the computing capabilities of the national labs to find solutions to real-world transportation energy challenges.

These initiatives are part of VTO’s Energy Efficient Mobility Systems (EEMS) Program. The EEMS Program’s mission is to conduct early-stage research at the vehicle, traveler, and system levels to create knowledge, tools, and solutions that increase mobility for individuals and businesses while improving transportation energy efficiency.

Big Data Solutions for Mobility

VTO’s EEMS program has launched a $2M multi-lab research initiative to develop new algorithms and big data tools that can model urban-scale transportation networks using real-world, near real-time data. The initiative will develop the data science approaches and HPC-supported framework for next-generation mobility systems modeling and operational analytics. This will deliver an understanding of transportation system efficiency opportunities that is not attainable with current approaches. Modeling informed by real-time data will allow transportation systems to respond to events such as accidents, weather, and congestion in such a way that optimizes the overall energy use of the system.

The Big Data initiative includes researchers from Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory, Argonne National Laboratory, and Oak Ridge National Laboratory as well as partners from academia and industry.


HPC4Mobility will provide cities, companies, transportation system operators, and others that qualify, access to national laboratory resources, including supercomputing facilities, data-science expertise, and machine-learning capabilities. These partnerships aim to discover opportunities for energy efficiency increases in mobility systems.

This investment supports innovative and scalable HPC4Mobility projects. These projects will uncover opportunities for energy efficiency gains by applying high-performance computing resources to emerging transportation data sets. Initial VTO funding of $500K has been provided to the participating laboratories. Each selected external partner will provide in-kind cost-share contributions.

The first year “seed” projects for HPC4Mobility include:

  • Lawrence Berkeley National Laboratory will work with the Los Angeles County Metropolitan Transportation Authority on HPC-enabled computation of demand models at scale to predict the energy impacts of emerging mobility solutions. Possible applications include modeling the impact of autonomous vehicles on transportation energy use and the hour-by-hour impact of ride hailing services on traffic congestion.
  • Oak Ridge National Laboratory will work with GRIDSMART Technologies, Inc. on reinforcement learning-based traffic control approaches to optimize energy usage and traffic efficiency.

Sponsored by DOE’s the Office of Energy Efficiency and Renewable Energy, the High Performance Computing for Mobility (HPC4Mobility) Program is part of the larger HPC4 Energy Innovation Initiative, a Department-wide effort comprised of, the Office of Energy Efficiency and Renewable Energy, the Office of Fossil Energy, and the Office of Nuclear Energy.

3 Ways Distilled Biodiesel Can Give You a Competitive Advantage

“What are some benefits of distilled biodiesel?”

The answer is as simple as 1, 2, 3 — the benefits wholesalers, retailers and fleets get with distilled biodiesel: 

  1. Superior cold weather performance
  2. Lower carbon intensity with decreased supply and price fluctuations through feedstock flexibility
  3. Easier blending
Those are the top three benefits we’ll focus on in this article. If you want to take a deeper dive into the topic, including the science behind distillation, download our free white paper on distilled biodiesel.

Superior cold weather performance

Distilled biodiesel has advanced cold flow properties because distillation does a better job than other purification methods at removing minor components that can contribute to filter plugging. Far too often people think Cloud Point is the only thing that matters when using biodiesel in the cold. Even with a higher Cloud Point, distilled biodiesel can outperform undistilled low cloud biodiesel in cold weather.

Feedstock flexibility

The ability to create high-quality biodiesel from a variety of feedstocks — feedstock flexibility, as we call it at REG — has a couple of big advantages. One is it can provide more nimbleness in the commodity markets. If a particular feedstock is experiencing price or supply fluctuations, we can turn to another feedstock and know that our end product will still meet ASTM and customer specifications. This, of course, is good for our customers, too. 

Another advantage of feedstock flexibility is the ability to make biodiesel from feedstocks such as animal fat, used cooking oil and inedible corn oil that can allow for lower carbon intensity (CI) scores. Carbon intensity is the measure of greenhouse gas emissions associated with producing and consuming a fuel. Some of the feedstocks with favorable CI scores can result in biodiesel with a higher Cloud Point, but with Cloud Point being less of an issue with a distilled product, users can get a fuel with lower carbon intensity that helps them reach sustainability goals and also performs well in cold weather. 

So to recap, under this single benefit of feedstock flexibility comes several other advantages, including supply, price and sustainability. 

Ease of blending

You may be sensing a theme related to the removal of minor components in the distillation process — and it has yet another benefit. It helps create the purest type of biodiesel. A purer biodiesel means there are fewer minor components. Fewer minor components means less effort is required to fully mix the biodiesel molecules and petroleum diesel molecules.

Louisiana Fleets Honored by LCF at 2017 Clean Fuel Leader Awards

EBR Schools, GreenSeasons and UL Lafayette take away top honors

Each year, Louisiana Clean Fuels recognizes fleets in its territory for use of alternative fuels, emissions reduction and fuel saving measures and honors outstanding fleets and projects. To qualify for the awards, fleets need only to participate in the Clean Cities Annual Reporting process by sharing their fuel usage and fleet information with Louisiana Clea Fuels, a U.S. Department of Energy designated Clean Cities Coalition since 2000.

The 2017 Awards are based on fuel statistics and data gathered for the 2016 Clean Cities Annual Report.

  • Rising Star
  • Innovative Project of the Year
  • Resilience Award
  • 2 Lifetime Achievement Awards
  • Various recognition awards for outstanding fleets

Rising Star: East Baton Rouge Parish School System

The 2017 Rising Star Award is for a fleet that has just begun its journey with alternative fuels. This particular fleet responded to the devastation of the great flood of August 2016 and decided to do something good for the children and their community by investing in cleaner burning, domestically produced alternative fuel buses for their district.

The East Baton Rouge Parish School System is the second largest school district in Louisiana serving over 42,000 students. The flood damaged homes and vehicles of its employees and students, the roads they use to travel, entire contents of school buildings, and the lives of its community. Thirty-five percent of employees and over 5,000 children were displaced by the flood. Over one hundred ten (110) school buses were destroyed and 189 school buses drivers displaced.  The Office of Transportation and the transportation shop were included in the seven administrative sites that flooded. Eight flooded schools were relocated to other school sites; and four non-flooded schools were relocated to make room for the displaced schools.

After the flood, the school system scraped together what funds they could and purchased 68 buses - 10 of which were propane. The school board also won DERA funding to offset the cost of more propane buses and has expressed their desire to purchase more.

Accepting the award for East Baton Rouge School System:

  • Warren Drake, Superintendent of Schools
  • Pat Friedrich - District Grant Writer
  • Gary Reese– Chief of Student Support Services

Resilience Award: GreenSeasons

The 2017 Resilience award goes to a Louisiana fleet whose commitment to alternative fuels was put to the ultimate test. Back in early 2016, they converted twenty-three of their trucks to CNG and started construction of a private, onsite slow-fill natural gas station. Everything seemed to be on track and going smoothly. Then, in August of 2016, the worst natural disaster to hit our country since Hurricane Sandy dumped nearly 7.1 trillion gallons of water on the southern half of our state. Every one of their vehicles was underwater as was their new private CNG station.

When asked why he wanted to stick with alternative fuels after everything was damaged, Chris CasseIberry said that reducing GreenSeason’s carbon footprint was just that important to him. He also needed to have a constant and reliable source of fuel, ensure that his trucks were properly fueled every night, and wanted to reduce his overall cost of fuel for his fleet. In addition to utilizing CNG in their fleet, GreenSeasons has eight commercial propane mowers. But he doesn’t plan to stop there. This company has big plans to eventually operate on 100% alternative and renewable energy sources.


Accepting the award for GreenSeasons:   Chris CasseIberry
