Newswise \u2014 Hydropower \u2014 Supply chain crunch<\/strong><\/p>\n

A new Department of Energy\u00a0report<\/a>\u00a0produced by Oak Ridge National Laboratory identifies several supply chain must-haves in maintaining the pivotal role hydropower will play in decarbonizing the nation\u2019s grid.<\/p>\n

The \u201cHydropower Supply Chain Deep Dive Assessment\u201d is part of a series of reports on energy sector readiness that spotlights the impacts of a burdened supply chain \u2014 from an aging workforce to a lack of domestic sourcing for components such as microchips and large steel castings for turbines.<\/p>\n

While the supply chain adequately supports the existing U.S. hydropower fleet, the sector is preparing for longer lead times in procuring components for new construction and modernization efforts in response to growing demand for hydropower.<\/p>\n

\u201cIt was illuminating to see how little public data are available to trace hydropower supply chains,\u201d said ORNL\u2019s Rocio Uria-Martinez. \u201cBut this analysis has brought all parties together to better inform policy and develop workable solutions.\u201d \u2014\u00a0Mimi McHale<\/em><\/p>\n

Tech transfer \u2014 Safer batteries on impact<\/strong><\/p>\n

Several electrolyte and thin-film coating technologies, developed at Oak Ridge National Laboratory, have been licensed by BTRY, a battery technology company based in Virginia, to make\u00a0batteries<\/a>\u00a0with increased energy density, at lower cost, and with an improved safety profile in crashes.<\/p>\n

The enabling technologies, called Safe Impact Resistant Electrolytes, or SAFIRE, are particularly suitable for application in the electric vehicles and aerospace industries.<\/p>\n

\u201cIn a lithium-ion battery, a thin piece of plastic separates the two electrodes,\u201d said ORNL\u2019s Gabriel Veith. \u201cIf the battery is damaged and the plastic layer fails, the electrodes can come into contact and cause the battery’s liquid electrolyte to catch fire.\u201d<\/p>\n

ORNL\u2019s technology<\/a>\u00a0mixes an additive into the conventional electrolyte to create an impact-resistant electrolyte. It solidifies when hit, preventing the electrodes from touching if the battery is damaged. This new stability reduces the need for bulky protective shielding.<\/p>\n

Imaging \u2014 Lithium light bright<\/strong><\/p>\n

Oak Ridge National Laboratory researchers demonstrated an electron microscopy technique for imaging lithium in energy storage materials, such as lithium ion batteries, at the atomic scale.<\/p>\n

The properties of energy storage materials stem directly from their atomic structures, which are only visible using electron microscopy. Today’s advanced electron microscopes are able to image heavy elements at atomic resolution. One challenge is simultaneously observing light elements including lithium, sodium and potassium, which are essential for modern\u00a0batteries<\/a>.<\/p>\n

Scientists at ORNL\u2019s Center for Nanophase Materials Sciences used \u201ccenter-of-mass\u201d scanning transmission electron microscopy, or CoM-STEM,\u00a0to observe lithium<\/a>\u00a0along with heavier elements in battery materials at atomic resolution.<\/p>\n

\u201cImaging light and heavy elements together is important for advancing energy storage materials, but many techniques require significant expertise or yield data that are difficult to interpret,\u201d said ORNL\u2019s Michael Zachman. \u201cCoM-STEM is a straightforward technique that will now be more accessible across the research community.\u201d<\/p>\n
