Italian startup testing PV sleepers on railway line
Greenrail Group has started deploying special its PV railroad-tie solution along a railway line in Emilia Romagna, Italy. The company designed the system according to the UNI 10349 standard.
US government funds pilot project for heated sand energy storage
The US Department of Energy is funding a pilot project to demonstrate the commercial viability of storing energy in heated sand, which is capable of producing 135 MW of power for five days.
Growatt launches new balcony storage solution
The new product combines the NEO 800TL-X Microinverter and the NOAH 2000 Battery. Up to four batteries can be stacked, for up to 8,192 Wh of storage capacity.
Sodium-ion batteries – a viable alternative to lithium?
While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand. Marija Maisch reports.
Evaluating the profitability of vanadium flow batteries
Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours.
How to convert PV plants with dual-axis trackers into agrivoltaic facilities
A Spanish group of researchers has investigated how much agricultural production may be hosted by existing ground-mounted PV plants using dual-axis trackers. They outlined a new methodology that reportedly enables to quantify how much space around and beneath the panels can be uses for agricultural purposes.
IIT Kanpur event focused on sustainable innovation and entrepreneurship starts today
IIT Kanpur’s annual event Abhivyakti’24, scheduled for March 15 and 16, 2024, provides a platform for the startup ecosystem to collaborate and develop sustainable solutions for a better future.
Perovskite thin film: Out with the old, in with the new
Silicon-perovskite tandem solar requires optimization of both approaches, and embodies the weaknesses of each. Meanwhile, the use of pure thin-film devices offers a cheaper, simpler, and more sustainable PV solution for the United States.
Indian scientists design 26.24%-efficient triple-junction all perovskite solar cell
The researchers simulated an all perovskite solar cell offering the advantage of effectively harnessing sunlight across a wide range of wavelengths. The device has the potential to achieve an open-circuit voltage of 3.76 V, a short-circuit density of 10.70 mA/cm², and a fill factor of 69.00%.
Battery prices collapsing, grid-tied energy storage expanding
From July 2023 through summer 2024, battery cell pricing is expected to plummet by more than 60% due to a surge in electric vehicle (EV) adoption and grid expansion in China and the United States.
