Record energy prices, particularly in Europe, are driving demand for renewables and energy storage. That is changing the equation for utility solar and wind investment and shortening project payback times to under a year in some regions. Storage deployment, driven by recent policy developments around the world, is also expected to get a big boost through to 2030.

Russian researchers have transmuted poisonous Sosnowsky’s hogweed into high-grade anode material for sodium-ion batteries. The obtained material has a Coulombic efficiency of 87%, which is on par with the best reported results for hard carbons synthesised from other raw materials.

The off-grid solar sector has shown resilience in the face of pandemic-related challenges, with 70 million people gaining access to electricity from early 2020 to the end of 2021. However, the ability to pay for solar energy kits has taken a hit.

US researchers have developed a novel fast-charging battery anode material, and GM has revealed a new focus on battery R&D. The European Parliament, meanwhile, has issued a number of proposals for alternative fuels infrastructure.

Researchers in Egypt have developed a synthesis method that uses the high microwave absorbance of silicon carbide content in rice straw ash and takes just 60 seconds to produce sodium iron phosphates-carbon nanocomposites (NaFePO4-C), which can be used as sodium ion battery cathodes and as symmetric supercapacitors.

An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.

US researchers have developed a new solid-state lithium-metal battery, and China’s SVOLT has started producing prototype solid-state cells. Toyota, meanwhile, has revealed plans to invest billions of dollars in battery production.

Southwest Research Institute (SwRI) has commissioned a first-of-its-kind pilot plant pumped heat energy storage demonstration facility with tech from US startup Malta. Its 10-150+ hour energy storage technology is said to be applicable in a range of grid-scale applications.

Solar Philippines, a Manila-based PV module manufacturer and project developer, is looking to secure at least 2,500 hectares of land to expand its 500 MW flagship solar project to 4 GW.

Hype and hope for solid-state batteries (SSBs) continues to grow as industries from automotive to storage bet big on the technology. Leading battery manufacturers and a roll call of start-ups are jostling to get from lab to fab. The reality of SSBs is in question though. As Marija Maisch reports, the window of opportunity for the decades-old technology to make the next big step toward commercialisation is now.
