Scientists Pinpoint Pathways for Carbon Dioxide Uptake of Cyanobacteria
Research performed by the Renewable and Sustainable Energy Institute (RASEI)—a joint effort between NREL and the University of Colorado, Boulder—shows how RASEI researchers traced the growth of individual cyanobacteria, providing new insights into the biological pathways that enable efficient photosynthetic growth, and ultimately high-value renewable fuels and chemicals.
NREL's John Farrell Honored for Leadership in Sustainable Fuels and Engines
Since taking the helm of NREL's vehicle technologies research in 2013, John Farrell has been instrumental in directing R&D initiatives for the U.S. DOE Office of Energy Efficiency and Renewable Energy's Vehicle Technologies Office, ranging from high-density energy storage to vehicle automation, as well as co-optimization of fuel and engine technologies to vehicle-to-grid interactions.
NREL Tool Quickly Provides Answers for Chemical Reactions
A new machine-learning tool developed at NREL has significantly speeded up calculating the thermodynamics of chemical reactions. Developed as part of the DOE Co-Optimization of Fuels & Engines initiative, the new tool—called ALFABET—makes it possible for researchers to identify the most promising fuels for lower emissions and greater engine efficiency in seconds rather than days.
