NREL Modeling and Analysis Delivers Science-Based Solutions for Big Transportation Challenges
As we accelerate toward a zero-emissions future, decision makers at the local, state, and federal levels continue to depend on NREL's deep transportation decarbonization expertise in support of realizing ambitious clean energy goals to slash greenhouse gas emissions, improve mobility access, and hasten the transition to widespread electrification.
Meeting these targets could lead to between 30 and 42 million electric vehicles (EVs) on U.S. roads by 2030, but a key question remains: Where are they all going to charge? NREL's premier EVI-X modeling suite of EV charging infrastructure analysis tools can help provide answers—from the type and number of chargers needed to where they should be built.
But that barely scratches the surface of what we've been up to. Notably, NREL's Lithium-Ion Battery Resource Assessment (LIBRA) model has become the go-to tool for examining complex factors that could impact the battery materials supply chain. The lab also co-authored the federal government's first national blueprint for transportation decarbonization, a coordinated strategy to eliminate nearly all greenhouse gas emissions from the domestic transportation sector. And NREL's first-rate technical assistance and deployment expertise is ensuring communities can integrate these tools and insights into their own planning efforts through the Clean Cities and Communities Coalition Network, the Clean Energy to Communities Program, and the Joint Office of Energy and Transportation's zero-emission charging and fueling infrastructure initiatives.
Using data-driven modeling and sophisticated analysis, NREL is equipping decision makers with the scientific solutions needed to successfully navigate toward a sustainable transportation future.
Drive on,

A new technical report explores material, economic, and operational factors that must be considered for future hydrogen blending research. The report is part of the HyBlend™ initiative.
Get To Know Our Team: Jason Lustbader
A conversation with NREL's Jason Lustbader, manager of NREL's Advanced Vehicles and Charging Infrastructure group.
What does your research focus on?
I support a number of projects within our Advanced Vehicles and Charging Infrastructure research group. Transportation electrification is a multidisciplinary, even transdisciplinary problem, and it requires a lot of different areas of expertise.
Half of our group works on the EV charging infrastructure needed to meet vehicle electrification demands. The other half of our group is focused on commercial vehicle decarbonization. We collect data on different commercial vehicle applications, from on-road trucking to medium- and heavy-duty off-road applications like agriculture, mining, and construction equipment as well as non-road applications like rail, aviation, and maritime technologies. We apply data analytics, modeling, and simulation to understand the vehicle and electric infrastructure barriers to decarbonizing these technologies. Then we work closely with different industry, research, and government agencies to look at how we can overcome them.
What single mobility challenge would you say we need to prioritize in the next 5 years?
If I could only pick one, I would say charging infrastructure. If we're going to scale battery-electric vehicles for passenger, commercial, and non-road applications, deploying charging infrastructure in a scalable, reliable, convenient, and cost-effective way is going to be critical. There's still a lot of work that needs to be done on high-power applications, not to mention the costs and vehicle design, to realize widespread electrification.
We will also need to adapt to these changes very rapidly. We're already seeing the effects of climate change in our everyday lives. Rapid decarbonization isn't just about changing our behaviors and attitudes—the technology must evolve in a way that meets peoples' needs. But in many ways, it's exciting to see the accelerated rate of change in technology and adoption. Many people are beginning to recognize that electric and alternately fueled vehicle technologies can offer a lot of benefits. As a researcher, it's exciting to be able to contribute toward a more decarbonized transportation system and see how our efforts play out in the real world.
