NREL's research stands at the forefront of exploring the new interaction between the transportation system and the electric grid, creating flexibility, economic advantages, and opportunities to optimize renewable energy use.
NREL's research on electric vehicle (EV) grid integration examines the interaction between electric vehicles, building energy systems, utility grids, and renewable energy sources. We work with automakers, charging station manufacturers, and utilities to test control systems and technologies that allow EVs to communicate with the smart grid and play an active role in building and grid management.

Fuel Cell Electric Vehicles and Hydrogen Fueling Infrastructure
What Our Partners Say
NREL (has) capabilities that in a lot of ways are ahead of the curve. As a car manufacturer, I want to concentrate on vehicle engineering and powertrain engineering, and [I] have the ability to do that. But I don't necessarily want to test the hose on a hydrogen station. That's out of my domain.
- Tim McGuire, Project Manager, Mercedes-Benz Research and Development North America
NREL researchers are developing tools and technologies to help expand hydrogen refueling infrastructure nationally. Research ranges from technical challenges such as testing new hydrogen fueling methods to outreach, education, and improving user experience at hydrogen fueling stations.
The Energy Systems Integration Facility (ESIF) at NREL covers all aspects of a hydrogen economy—from renewable hydrogen production to its use in fuel cells—making it the most advanced and highly instrumented hydrogen technology testing facility in the world.
