Energy security drives the initiatives, Hammack said, adding that increased usage of renewable energy on military installations would enable them to operate even if local powergrids go down. New sources of clean energy will vary among installations, he said, and will include solar, wind, biomass and geothermal developments.
By rapidly ramping up and down in response to fluctuations in wind and solar power, the technology will enable the integration of more renewable resources into the powergrid. In 2010, GE and HE expanded their relationship, forming a joint venture to serve China’s wind energy industry.
Their innovations could make this critical piece of infrastructure not only more resistant to supply chain weaknesses, but also better suited to the powergrids of the future. The sets of wires, called windings, arent connected, but through electromagnetic induction across the core, current transfers from one coil to the other.
For the field test, researchers will deploy aged EV batteries at the University of California (UC), San Diego’s campus-wide electric powergrid. This activity is sponsored by DOE’s Office of Energy Efficiency and Renewable Energy. NREL PHEV/EV Li-Ion Battery Second-Use Project.
