Sandia addresses barriers to hydrogen-fueled internal combustion engines
News Article, November 18, 2024 • Pre-ignition is one of the key barriers preventing hydrogen-fueled combustion engines from achieving efficiency and power-density parity with current diesel powertrains. To address this issue, Sandia has developed an experimental framework to isolate and study various sources of pre-ignition. The research team recently updated the framework with a new methodology...

Sandia National Labs joins DOE’S SHASTA initiative to advance underground hydrogen storage capabilities
News Article, September 8, 2022 • The U.S. Department of Energy’s (DOE) Subsurface Hydrogen Assessment, Storage and Technology Acceleration (SHASTA) collaboration, a project designed to use unique capabilities and expertise of key national laboratories to determine the viability, safety, and reliability of storing hydrogen in subsurface environments, has added Sandia National Laboratories as its fourth research...

Sandia switches to hydrogen weather balloons
News Article, May 24, 2023 • Hundreds of miles north of the Arctic Circle, Sandia National Laboratories researchers ensure the collection of important weather and climate data. By switching the gas used in their weather balloons, they have reduced their metaphorical footprint on the fragile Arctic ecosystem. More than three years ago, the Sandia-operated atmospheric measurement...

About three years ago, Sandia National Laboratories switched from launching helium-filled balloons to launching hydrogen-filled balloons to reduce costs and carbon emissions. (Photo by Ben Bishop)

Stunning discovery: Metals can heal themselves
News Article, August 8, 2023 • Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution — one in which self-healing engines, bridges and airplanes...

Using X-ray science to hit hydrogen storage targets
News Article, November 7, 2023 • Using soft X-ray techniques available through Berkeley Lab’s Advanced Light Source (ALS), a Sandia team including Mark Allendorf and Farid El Gabaly with collaborators from the Hydrogen Materials Advanced Research Consortium (HyMARC) are probing the chemistry of promising hydrogen storage materials to understand how they absorb and release hydrogen. The...

Video: Validating models for safety codes and standards
News Article, May 10, 2024 • Earlier this year, a test series at Sandia collected data to validate the models used for hydrogen safety codes and standards. Go behind the scenes with the research team who ran the test with partners from the National Renewable Energy Laboratory and support from US DOE Office of Energy Efficiency...
