Using light instead of heat, researchers at ORNL have found a new way to release carbon dioxide, or CO2, from a solvent used in direct air capture, or DAC, to trap this greenhouse gas. The novel approach paves the way for economically viable separation of CO2 from the atmosphere.

The Spallation Neutron Source — already the world’s most powerful accelerator-based neutron source — will be on a planned hiatus through June 2024 as crews work to upgrade the facility. Much of the work — part of the facility’s Proton Power Upgrade project — will involve building a connector between the accelerator and the planned Second Target Station.

ORNL has launched a new entrepreneurial start-up program, Safari, as an addition to DOE's Office of Technology Transitions Practices to Accelerate the Commercialization of Technologies program. Safari seeks to connect post-exit entrepreneurs with commercially relevant technologies developed by world-leading scientific experts, which could provide the basis for a new business.
