Silicon anode lithium-ion battery cell with 500 Wh/kg density
Amprius has obtained third-party performance verification for a battery cell that offers high power density in a lightweight package.
FERC says 1,700 GW of US renewables still awaiting interconnection
The US Federal Energy Regulatory Commission (FERC) says that just 86 GW of power projects based on fossil fuels are awaiting interconnection, while 1,700 GW of solar, wind, storage remain delayed.
Novel oxygen-ion battery may offer longer lifespan, claims TU Wien
Austrian scientists have created a lab-scale, solid-state, oxygen ion battery based on mixed ionic electronic conducting (MIEC), which is a special class of non-flammable electroceramic materials. The battery has around 30% of the energy density of lithium-ion batteries but can purportedly achieve a longer lifespan.
Solar curtailment vs. storage
Swiss researchers have looked at whether storage could be cheaper than curtailment in medium-voltage distribution networks with significant amounts of PV capacity. They considered storage costs, operational costs, grid constraints, electricity costs, PV generation models, and loads.
Australian developer plans gigawatt-scale solar, battery project
Skylab, a solar tracking distributor and renewable energy project developer, has unveiled ambitious plans to build about 1 GW of solar and battery energy storage facility in the Australian state of Queensland.
Poland includes heat pumps in residential solar rebate program
The Polish government says it will launch the fifth round of its Mój Prąd program in April. The scheme will offer rebates for air and ground heat pumps, as well as residential batteries.
Australian startup using second-life Nissan Leaf EV battery packs for storage
Relectrify, an Australian battery technology startup, has secured approval from the International Electrotechnical Commission for its ReVolve energy storage product, which opens the way for it to globally scale up its cell-level control tech.
Key takeaways from Solar Solutions
The latest edition of Solar Solutions, the largest solar trade show in the Netherlands, showed that the Dutch PV market is set to stabilize in terms of volumes, while preparing to integrate more heat pumps and storage. The solar sector is asking to move away from net metering to create a more resilient distributed-generation PV market.
Australia startup announces nanosilicon tech that may help build better batteries
Australian materials tech developer Kinaltek has unveiled a one-step production process that it says can convert common silica powders into battery-grade nanosilicon for less than 5% of the cost of existing technologies. The innovation paves the way for the use of silicon nanoparticles in high-performance lithium-ion batteries.
Around 800 Sungrow batteries affected by outage in Germany
After 800 Sungrow batteries were impacted by an outage, the Chinese manufacturer informed its local German partners about the solution to the problem. However, it remains unclear how quickly the affected battery management systems can be replaced.
