Linear generator running on hydrogen, ammonia
Mainspring Energy, a US linear generator specialist, has adapted its technology so its generators can run on hydrogen and ammonia. It said the generators can ramp up and down quickly via solar, with the ability to dynamically switch between different kinds of fuels.
Four-mode hydrogen plant to accommodate renewables
Bio-FlexGen, an EU research project, seeks to develop a combined heat and power plant (CHP) system with hourly, daily and seasonal flexibility via hydrogen production from biomass.
Single-axis trackers on commercial rooftops increase generation by 37%
Alion Energy trackers thread the return-on-investment needle with productivity gains from white roofs and bifacial modules, while design aggressively maximizes module count.
DMEGC launches M10 rooftop solar modules with 410 W of output
China’s DMEGC has released new solar panels with power conversion efficiencies of up to 21.2% and temperature coefficients of -0.33% per degree Celsius. They can be used with maximum system voltages of 1,000 V or 1,500 V.
Photon-enhanched rechargeable batteries for solar storage
Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.
Longi’s heterojunction solar cell hits 26.5%
Germany’s Institute for Solar Energy Research Hamelin has confirmed that Longi’s new n-type heterojunction solar cell has achieved a power conversion efficiency of 26.5%.
RETC releases 2022 Module Index Report
The Renewable Energy Test Center has released a new report on PV module performance.
Solar module for lightweight applications from France
French manufacturer 2CA has developed a 20%-efficient solar module that weighs four times less than a glass-glass module of the same size. It claims the frameless, self-supporting panel could be used for lightweight applications at military camps and other remote locations.
Automatically generated databases for perovskite, dye-sensitized solar cells
University of Cambridge scientists have created new databases for dye-sensitized and perovskite cells, respectively. They used the ChemDataExtractor text-mining toolkit to collect the data.
Solar window generates electricity, thermal energy
A research team in Hong Kong has built a solar window that can generate power on the external side via a luminescent solar concentrator and thermal energy on the internal side via transparent solar absorbers.
