Direct air capture (DAC) technologies that extract carbon dioxide directly from the atmosphere are critical for mitigating effects of climate change.

Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches.

ORNL has developed a new thermal energy storage design utilizing low conductivity organic phase change materials.

The technologies provide a coating method to produce corrosion resistant and electrically conductive coating layer on metallic bipolar plates for hydrogen fuel cell and hydrogen electrolyzer applications.

The invention addresses the long-standing challenge of inorganic phase change materials use in buildings envelope and other applications by encapsulating them in a secondary sheath.

Sodium-ion batteries are a promising candidate to replace lithium-ion batteries for large-scale energy storage system because of their cost and safety benefits.

Knowing the state of charge of lithium-ion batteries, used to power applications from electric vehicles to medical diagnostic equipment, is critical for long-term battery operation.
