Crosscutting NREL Research Advances Plug-In Hybrid Electric Vehicles.
In the 1990s, NREL worked to advance hybrid electric vehicles, particularly propulsion systems, building the technology's viability in the marketplace. Today, NREL is working with industry and other national labs to take this concept one step further with plug-in hybrid electric vehicles. Plug-in hybrids have the potential to cut fuel consumption by more than 50 percent. But what will it take to advance plug-in hybrid technology for market acceptance?
