pv magazine Roundtables Europe 2022: Which battery to choose?
Amid growing concerns about the global supply of raw materials, which battery chemistries have the best chance, if any, of supplanting lithium-ion devices?
Lithium-ion fire fears spark recall of 433,000 solar LED umbrellas in US, Canada
The US Consumer Product Safety Commission and Health Canada have issued a joint recall of patio umbrellas due to fires caused by the overheating of lithium-ion batteries.
Decentralized plant to convert ammonia into hydrogen
Spain’s Tecnalia is developing a facility that will provide provide clean fuel for a hydrogen bus fleet in Birmingham, England.
Inverted perovskite-silicon tandem solar cell with 29.3% efficiency
Researchers in Saudi Arabia have built an inverted perovskite-silicon tandem device with a 1 nm thick interlayer based on magnesium fluoride (MgFx). They claim it can stop voltage losses and increase power conversion efficiency, while retaining 95.4% of its initial efficiency after 1,000 hours.
Prefab floating solar for easy installation
A Norwegian startup has patented a floating solar system made of panels laminated on top of double-aluminum sheets. The pre-stringed floats are rolled out on site and towed into place.
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.

Down below, you can see a quickfire summary of some of the events held and points raised on day one of pv magazine‘s Roundtables Europe event.
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.
