Engineers develop tools to share power from renewable energy sources during outages

 A team of engineers at the University of California San Diego has developed algorithms that would allow homes to use and share power from their renewable energy sources, such as solar panels, during power outages. The approach involves strategically disconnecting the devices, called solar inverters, from the grid.  Full Story

From Theory to Microgrid: New Ideas from the Sustainable Power and Energy Center Research Summit

Software that can design new materials for energy storage. X-ray visualization techniques to “see” inside batteries and solar cells. Green processes for making batteries. These were some of the projects presented at the Sustainable Power and Energy Center (SPEC) Research Summit at the University of California San Diego on July 18. Full Story

Nanoengineer receives award from Energy Department to advance solar power technologies

University of California San Diego nanoengineering professor David Fenning has received an award from the U.S. Department of Energy SunShot Initiative to lead a new project aimed at advancing research in solar photovoltaic technologies. The project will focus on developing a high resolution tool that can detect moisture in photovoltaic modules and predict how it will affect the modules’ performance. Full Story

Electrolytes made from liquefied gas enable batteries to run at ultra-low temperatures

Engineers at the University of California San Diego have developed new electrolytes that enable lithium batteries to run at temperatures as low as -60 degrees Celsius with excellent performance -- in comparison, today's lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as cold as -80 degrees Celsius -- their current limit is -40 degrees Celsius. Full Story

Nuvve and UC San Diego to Demonstrate Vehicle-to-Grid Technology through Energy Commission Grant

The United States is home to more than half a million electric vehicles. What if all those vehicles could be turned into virtual power plants, feeding energy back into the grid while connected via a charger? Thanks to a $7.9 million grant from the California Energy Commission, San Diego-based Nuvve Corporation will demonstrate how this technology could work on a large-scale with help from UC San Diego.

Printed, flexible and rechargeable battery can power wearable sensors

Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics. The work appears in the April 19, 2017 issue of Advanced Energy Materials.    Full Story

UC San Diego nanoengineers developing next-gen solar cells in collaboration with EMSL

To engineer the next generation of low-cost, high-efficiency solar panels, the team is using capabilities and expertise at the Environmental Molecular Sciences Laboratory, or EMSL, a DOE Office of Science user facility, to understand how solar cells work at the molecular level. Full Story

Engineers Receive $2.9 Million to Transform Power Distribution on the Grid

A team of researchers from the University of California San Diego and the University of Illinois has been awarded a $2.88 million grant by the Advanced Research Projects Agency-Energy (ARPA-E), a government agency that advances high-potential, high-impact energy technologies that are too early for private-sector investment. The researchers, led by Professor Sonia Martinez from the Department of Mechanical and Aerospace Engineering at UC San Diego, will develop methods that are poised to transform the way electric power is distributed on the grid.
