This prototype heat pump installed at the Ohio field test site in January 2015 produced savings of more than 40 percent compared to the baseline heat pump.

People in cold climates who heat with electricity could realize savings of up to 70 percent with a new heat pump developed by Oak Ridge National Laboratory and Emerson Climate Technologies. The tandem compressor system, developed through a cooperative research and development ag...

Ask a biofuel researcher to name the single greatest technical barrier to cost-effective ethanol, and you’re likely to receive a one-word response: lignin. Cellulosic ethanol—fuel derived from woody plants and waste biomass—has the potential to become an affordable, renew...
In pure water, lignin adopts a globular conformation (left) that aggregates on cellulose and blocks enzymes. In a THF-water cosolvent, lignin adopts coil conformations (right) that are easier to remove during pretreatment.
When the Ford Motor Company’s first automobile, the Model T, debuted in 1908, it ran on a corn-derived biofuel called ethanol, a substance Henry Ford dubbed “the fuel of the future.”
ORNL researchers are developing an idealized collector molecule that has a shape complementary to the surface atomic structure of xenotime, a rare earth yttrium-rich phosphate mineral.

Ensuring a reliable supply of rare earth elements, including four key lanthanides and yttrium, is a major goal of the Critical Materials Institute (https://cmi.ameslab.gov) as these elements are essential to many clean-energy technologies. These include energy-efficient lighting, ...

Researchers at the Department of Energy’s BioEnergy Science Center are looking beyond the usual suspects in the search for microbes that can efficiently break down inedible plant matter for conversion to biofuels. A new comparative study from the Oak Ridge National La...
This section of a serpentine channel reactor shows the parallel reactor and feeder channels separated by a nanoporous membrane. At left is a single nanopore viewed from the side; at right is a diagram of metabolite exchange across the membrane.
Lives of soldiers and others injured in remote locations could be saved with a cell-free protein synthesis system developed at the Department of Energy’s Oak Ridge National Laboratory. The device, a creation of a team led by Andrea Timm and Scott Retterer of the ...

Researchers at the Department of Energy’s Oak Ridge National Laboratory have received six R&D 100 Awards, increasing the lab’s total to 193 since the award’s inception in 1963. The competition, sponsored by R&D Magazine, recognizes advances in the nation’s ...

Using high-performance computing, ORNL researchers are modelling the atomic structure of new alloys to select the best candidates for physical experimentation.

The Department of Energy’s Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological

Chaitanya Narula led analysis of an ORNL biofuel-to-hydrocarbon conversion technology to explain the underlying process.

A new study from the Department of Energy’s Oak Ridge National Laboratory explains the mechanism behind a technology that converts bio-based ethanol into hydrocarbon blend-stocks for use as fossil fuel alternatives. Scientists have experimented for decades with a cl...
