NATIONAL RENEWABLE ENERGY LABORATORY (NREL)
HOW NREL IS SOLVING TODAY'S ENERGY CHALLENGES
NREL has decades of focused leadership in clean energy research, development, and deployment. No other institution has the long-standing expertise and breadth of knowledge that will form the foundation of the clean energy transition.
​
From our work in basic sciences to systems engineering and analysis, our researchers are focused on solving high-priority problems that result in market-ready solutions. Engaging in partnerships with forward-thinking commercial organizations, universities, foundations, and state, federal, and tribal governments ensures our work is relevant and applicable to today's energy problems.

FUELS AND COMBUSTION RESEARCH
NREL's fuels and combustion research provides the crucial connection between fuel properties and molecular structure, targeting fuel design and production with the right chemistry for the intended transportation application.
​
We focus on researching and developing net-zero-carbon fuels for difficult-to-decarbonize sectors such as heavy-duty trucking, off-road vehicles, rail, marine, and aviation.
RESEARCH AND DEVELOPMENT
We provide the scientific building blocks needed to spur innovation through fundamental fuels and combustion research and engineering.
HEAVY-DUTY ON- AND OFF-ROAD VEHICLE EMISSIONS AND FUEL ECONOMY
For heavy-duty vehicles, both on- and off-road, NREL's extensive engine- and vehicle-based research quantifies and validates the fuel economy and emissions impacts of advanced fuel formulations and combustion strategies.
​
​We conduct most of this research at the Renewable Fuels and Lubricants (ReFUEL) laboratory. Typical studies look at the performance, fuel consumption, and nitrogen oxide (NOx) emissions tradeoffs of biofuels, such as biodiesel, renewable diesel, or advanced fuels from biomass pyrolysis or hydrothermal liquefaction.
