Scientists in the United States developed a lithium-sulfur battery using a commercially available carbonate electrolyte, that retained more than 80% of its initial capacity after 4000 cycles. The group used a vapor deposition process which unexpectedly produced a form of sulfur that did not react with the electrolyte, overcoming one of the key challenges for this battery chemistry.

Soluna’s new generator can be combined in a two-unit system to reach a capacity of 2.5kWh. It features built-in 120V(AC) output, continuous AC output power of 1,200W, and peak output of up to 2,400W.

Verdagy has secured a $25 million investment for its new electrolyzer technology, which provides hydrogen fuel for heavy industrial applications. The membrane-based technology uses large active area cells, high current densities, and broad operating ranges to deliver hydrogen at scale.

Norwegian analyst Rystad Energy has warned the solar industry could suffer the same effects of rising input prices as onshore wind developers grappling with ever more costly steel, with much hinging on how much solar panel raw material polysilicon can be manufactured.

Greenko Group will provide Ayana with 6 GWh of pumped-hydro storage capacity from its project in Andhra Pradesh, allowing Ayana to provide firm power to offakers.

Seaborg Technologies, a Danish manufacturer of molten salt nuclear reactors, has turned a technology that was originally developed for nuclear power into a large-scale storage solution for wind and solar. It has developed a storage system that uses renewable energy to heat salt with electrical heaters, based on two-tank molten salt storage designs developed for concentrated solar power plants.

The selected developer will be required to set up a 25 kW green hydrogen project at Sonam Norboo Memorial (SNM) Hospital in the Leh district, for the supply of electricity, heat, and oxygen to the hospital. Bidding closes on March 10.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

A pair of researchers from UC San Diego has proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.

U.S-based solid-state battery start-up Sparks has opened a pilot plant for its patented lithium battery technology based on zero cobalt cathodes. The company wants to challenge China’s dominance in next-gen battery development.
