Surveilling carbon sequestration: A smart collar to sense leaks
December 13, 2022 – 5:00 am
ALBUQUERQUE, N.M. — Sandia National Laboratories engineers are working on a device that would help ensure captured carbon dioxide stays deep underground — a critical component of carbon sequestration as part of a climate solution. Carbon sequestration is the process of capturing CO2 — a greenhouse gas that traps heat in the Earth’s atmosphere — […]
Sandia studies vulnerabilities of electric vehicle charging infrastructure
November 15, 2022 – 5:00 am
ALBUQUERQUE, N.M. — With electric vehicles becoming more common, the risks and hazards of a cyberattack on electric vehicle charging equipment and systems also increases. Jay Johnson, an electrical engineer at Sandia National Laboratories, has been studying the varied vulnerabilities of electric vehicle charging infrastructure for the past four years. Johnson and his team recently […]
Propelling wind energy innovation
September 8, 2022 – 5:00 am
LIVERMORE, Calif. — Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers developed a fundamentally new type of rotary electrical contact. Sandia is now ready to partner with the renewable energy industry to develop the next generation of direct-drive wind turbines. Sandia’s Twistact technology takes a […]
Back to the drawing board: Reinventing offshore wind turbines
August 16, 2022 – 5:00 am
ALBUQUERQUE, N.M. — Brandon Ennis, Sandia National Laboratories’ offshore wind technical lead, had a radically new idea for offshore wind turbines: instead of a tall, unwieldy tower with blades at the top, he imagined a towerless turbine with blades pulled taut like a bow. This design would allow the massive generator that creates electricity from […]
“We’ve Got the Power”: Sandia technology test delivers electricity to the grid
August 9, 2022 – 5:00 am
ALBUQUERQUE, N.M. — For the first time, Sandia National Laboratories researchers delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. The Brayton cycle is named after 19th […]
20th anniversary of Sandia tribal energy internship program
July 13, 2022 – 5:00 am
ALBUQUERQUE, N.M. — 2022 marks a major milestone for Sandia National Laboratories’ groundbreaking tribal energy internship program: two decades of meeting the growing renewable energy technical needs of Native American tribes and providing valuable, real-world experience for Native and Alaska Native STEM students. “My hope for the interns is for them to be leaders in […]
Using the power of the sun to roast green chile
July 6, 2022 – 5:00 am
ALBUQUERQUE, N.M. — Every August and September the unmistakable pungent aroma of roasting green chile permeates the air across New Mexico and neighboring states. This delectable staple of regional cuisine is green in color, but roasting the chile pepper to deepen the flavor and make the inedible skin easier to remove is hardly environmentally friendly. […]
Exploring explosives for expanding geothermal energy
June 21, 2022 – 10:02 am
ALBUQUERQUE, N.M. — Why are scientists setting off small-scale explosions inside 1-foot cubes of plexiglass? They’re watching how fractures form and grow in a rock-like substance to see if explosives or propellants, similar to jet fuel, can connect geothermal wells in a predictable manner. Geothermal energy has a lot of promise as a renewable energy […]
Powering the moon: Sandia researchers design microgrid for future lunar base
May 11, 2022 – 5:00 am
ALBUQUERQUE, N.M. — Sandia National Laboratories is well-known for designing reliable and resilient microgrids for military bases and vital city services. Now, Sandia researchers are working with NASA to design one for the moon. This is not the first time Sandia has partnered with NASA to power equipment on the moon. In fact, Sandia provided […]
Seashell-inspired Sandia shield protects materials in hostile environments
May 3, 2022 – 11:26 am
ALBUQUERQUE, N.M. — Word of an extraordinarily inexpensive material, lightweight enough to protect satellites against debris in the cold of outer space, cohesive enough to strengthen the walls of pressurized vessels experiencing average conditions on Earth and yet heat-resistant enough at 1,500 degrees Celsius or 2,732 degrees Fahrenheit to shield instruments against flying debris, raises […]
