Battery roundup: funding for zinc-based storage, improved lithium-ion, new solid-state batteries
Venture capital is still flowing to energy storage startups and the march to improve a wide variety of battery chemistries continues.
US scientists claim clear-sky irradiance model provides better results for module testing
Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.
Shutdown continues at Hanergy-owned Alta Devices, high-efficiency PV pioneer
Alta Devices has not located a white-knight investor to save the company and resume its PV cell production. That means no health care or COBRA for its furloughed employees.
Ten research teams aim for long-duration storage at 5¢/kWh
To get long-duration storage costs down to 5 cents per kilowatt-hour, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies—even thermovoltaics.
5 stories that sparked conversation in 2019
Certain articles at pv magazine strike a chord with readers and spark greater discussion among the community. Here are the most discussed articles of 2019 at pv magazine USA.
Tesla to hide ‘solar test-house’ under tents at Fremont site
Lora Kolodny at CNBC uncovered a recently granted building permit that allows Tesla to put up “two canopy covers” over its new “solar test houses.” Earlier this year, Tesla CEO Elon Musk announced that 2019 was “the year of the solar roof.”
US research lab rewires solar cell increasing efficiency to 27.3%, sees path to greater than 32%
NREL has published a paper showing an experimental solar cell, with a unique technique for wiring two separate solar cells into one, that increased the cell’s efficiency by 4%. As well the document offer a respectable review of other technologies being developed.
Alta Devices hopes outside investors will revive the Hanergy-owned thin-film GaAs solar firm
Alta’s COO: “An agreement has been reached between Alta Devices and Hanergy to allow Alta to bring in outside investors to breathe new life into the company, and to get the thin film GaAs technology leader back on track.”
Federal grants aim to spark investment in U.S. solar manufacturing
Seven early-stage solar manufacturing firms have won U.S. Department of Energy grants to develop prototypes, which they could use to help attract private investment. DOE’s 21 PV research and development grants may hold more interest for established manufacturers.
Saving water with solar and wind
Scientists at Princeton have found solar and wind energy offer the added environmental benefit of reducing water usage, by comparison with hydroelectric dams. Their findings, say the researchers, could have a positive impact on groundwater sustainability in drought-prone regions such as California, where they conducted a case study.
