US startup uses agricultural waste to produce low-cost, safe batteries
US-based start-up SorbiForce uses no toxic products or metals in production of its batteries. It claims its systems are cheaper and safer than lithium-ion batteries and have near zero end-of-life waste.
High-efficiency, all-solid-state sodium-air battery achieves energy efficiency of 86%
Researchers in South Korea have successfully demonstrated the use of free ambient air as a fuel leveraging a sodium-based solid electrolyte to tackle the carbonate issue that has been holding back the rollout of metal-air batteries. Their sodium-air battery cell has demonstrated high efficiency, incresed energy density, and a broad voltage range.
Texas to host 300 MW of geomechanical energy storage projects
Quidnet Energy, a provider of geomechanical energy storage (GES) technology, has joined hands with distributed energy resources developer Hunt Energy Network to deliver 300 MW of storage projects in the Electric Reliability Council of Texas (ERCOT) grid operating region.
Australian hydrogen developer hits purity high in testing
Natural hydrogen explorer Gold Hydrogen says it has uncovered 95.8% pure hydrogen at its Ramsay Project on South Australia’s Yorke Peninsula as it seeks to tap into growing demand for the gas as a clean energy source.
Poland’s new capacity market auction could hamper storage deployment
The draft parameters for this year’s capacity market auction in Poland could make the rollout of battery energy storage systems (BESS) much more difficult. The document proposes a significant reduction to the BESS derating factor that could be particularly harmful for longer duration storage systems.
Long-duration energy storage poised to outcompete lithium-ion batteries
While most long-duration energy storage (LDES) technologies are still early-stage and costly compared to lithium-ion batteries, some have already or are set to achieve lower costs for longer durations, finds BloombergNEF.
Australian miner pushes ahead with 20 GWh pumped hydro project
Evolution Mining is moving forward on a AUD 7 billion ($4.64 billion) plan to build a 2 GW/20 GWh pumped hydro electricity generation facility in the pit of a 20-year-old gold mine in Australia.
Producing hydrogen fuel from solar power and agricultural waste
Using 600% less voltage to produce hydrogen, a research team at the University of Illinois Chicago has developed a new method for splitting water.
Svolt abandons plans to open battery factory in Germany
Chinese battery manufacturer Svolt has cancelled plans to open a plant in the German state of Brandenburg. Meanwhile, its plans for cell production in Saarland, southwest Germany, continue to be delayed.
Combining residential air heat pumps with air-geothermal heat exchangers
Researchers in Italy have found that combining residential air heat pumps with air-geothermal heat exchangers may reduce power consumption by up to 30%. They tested the proposed combination using Matlab in a passive single-family building located in Valtellina, northern Italy.
