Missile strike destroys solar plant in Ukraine
Two Russian missiles have hit a ground-mounted solar plant near Kharkiv, Ukraine. According to the manager of the plant, the missile attacks produced holes at the site that measured 6 meters deep and 11 meters in diameter.
‘Pulsed Joule heating’ tech to remove snow, frost, ice from solar modules
University of Illinois scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.
Hanwha Solutions to expand solar cell and module manufacturing in the United States and Korea
Hanwha announces an investment of $320M in cell and module manufacturing capacity expansions to meet the growing global demand for sustainable energy.
How grid-forming inverters may enhance grid synchronization
US researchers have investigated how grid-forming inverters could help to resolve network synchronization issues. They have found that multi-loop devices could offer strong damping support in power systems with intermittent renewables.
MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries
The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.
