ORNL building technologies scientists have been instrumental in the research, development and deployment of heat pump water heaters for use in residential applications.
Buildings researchers demonstrated advanced technologies that reduced, by greater than 50 percent, the 1993 National Appliance Energy Conservation Act standard energy consumption for a 20 ft. top-mount, automatic defrost, refrigerator/freezer.
ORNL buildings researchers were the first to accurately evaluate the effectiveness of a low global warming potential, or GWP, refrigerant known as R-448A.
ORNL researchers successfully demonstrated the first 270-kW wireless power transfer to light-duty electric vehicle using the ORNL-developed polyphase wireless charging system.
ORNL-developed recycling technologies help recover rare earth materials from old hard drives and spent lithium-ion batteries.
ORNL researchers have developed an orchestrator to automate management of interconnected microgrids powered by renewable energy, allowing them to support each other if one part becomes compromised.
ORNL fuels, engines and emissions scientists proved that gasoline containing 15% ethanol (E15) would not cause emission control system failure in light-duty vehicles.
An ORNL-patented cascade multilevel inverter was developed 30 years ago and is widely used today by global energy, machinery and plant solution providers.
ORNL researchers have produced and maintained the Department of Energy’s Transportation Energy Data Book which serves as the definitive mobility trend guide for industry, policymakers, researchers and consumers.
ORNL demonstrated the use of additive manufacturing in the production of hydrofoils and spokes for small hydropower systems.
ORNL developed a 3D-printed precast concrete mold using a carbon fiber reinforced thermoplastic known as CF-ABS.
ORNL invented and deployed a modal tap testing system for the calibration of CNC machines.
ORNL researchers 3D-printed a single-piece, recyclable natural-material floor panel tested to be strong enough to replace construction materials like steel.
ORNL researchers developed a Smart Smoke Alarm that used sophisticated algorithms to more accurately identify fires, offering much faster detection of smoldering fires than conventional technology at the time.
ORNL researchers developed a retinal scanning analysis software in the early 2000’s that was an early precursor to the modern technology used in telemedicine to recognize eye diseases such as diabetic retinopathy.
ORNL researchers developed and now operate the first North American power grid frequency monitoring network to cover the entire grid.
