[UniEnergy (US) and Rongke (China)] plans to install an 800MWh vanadium flow battery (VFB) — the world’s largest such system — … in northern China
The battery arrays’ deployed will comprise up to 10, 20 MW/80 MWh VFB [vanadium flow battery] systems.
During extreme weather events the Dalian peninsula has experienced stress on its electricity grid. After full commissioning, the VFB batteries will be able to peak shave approximately 8% of Dalian's expected load in 2020. In addition, the batteries will form an additional load center, which will enhance grid stabilization including securing the power supply and providing black-start capabilities in the event of emergency.
Co-founded and directed by Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Kristin Persson, the Materials Project uses supercomputers to calculate the properties of materials based on first-principles quantum-mechanical frameworks
While other research groups have made their data publicly available, what makes the Materials Project so useful are the online tools to search all that data. The recent release includes two new web apps—the Molecules Explorer and the Redox Flow Battery Dashboard—plus an add-on to the Battery Explorer web app enabling researchers to work with other ions in addition to lithium.
The researchers were able to double the energy capacity of what had previously been achieved for this kind of multivalent battery. The study has been published in the journal Energy & Environmental Science in an article titled, "A High Capacity Thiospinel Cathode for Mg Batteries."
[Australia Vanadium, AVL] has purchased a vanadium electrolyte pilot plant from leading UK technology company C-Tech Innovation Ltd (C-Tech).
The pilot plant is the first of its kind in Australia and will test and verify vanadium materials for use in vanadium redox flow batteries.
Raw materials such as vanadium require processing in order to prepare them for battery use. This relationship with C-Tech, leveraging its existing technologies and exciting new ideas, provides AVL with further opportunities to grow.
Elon Musk proposed combining his electric-car and solar-energy companies, in a bold effort to consolidate his holdings and offer widespread clean-energy products from vehicles to power in homes.
Tesla Motors Inc., Mr. Musk’s Palo Alto, Calif., electric-car company, on Tuesday offered to acquire SolarCity Corp. in a stock deal valuing it at up to $2.8 billion. Mr. Musk is the chairman and largest shareholder of both companies.
Redflow’s new ZCell home battery, launched in March , is a 10 kilowatt hour (kWh) flow battery that can ‘timeshift’ solar power from day to night, store off-peak power for peak demand periods and support off-grid systems. Redflow and Redback have been able to fully integrate the ZCell battery with Redback’s Smart Hybrid Solar Inverter System, which manages energy supplies from the grid, PV solar panels and a battery. ZCell with the Redback inverter will enable household and commercial users to achieve greater savings by self-consuming more of their on-site generated power.
Australia is transitioning to lower emission energy systems, with one in five homes around the country equipped with solar. Due to the popularity of home solar systems over recent years, the government plans to minimise the subsidies to solar bonus schemes, with the NSW scheme ending on 31st December 2016.
At the end of the day, the Powerwall has the same li-ion battery cells in it as any other li-ion-based storage product: Asian-sourced batteries that are arranged in packs,” says Jay Whitacre, a professor of engineering and public policy at Carnegie Mellon University and the founder of Aquion Energy, which makes batteries for residential use. “It's basically off-the-shelf cell technology.”
Gildemeister's offer achieved the highest number of points in the price and quality categories. The two CellCubes used in the project are based on vanadium redox flow technology and have a rated output of 400 kW and a capacity of 1,120 kWh.
The system is scheduled to be put into operation in July 2016, and final approval is expected for September this year.
In contrast to lead batteries or lithium-ion batteries, redox flow batteries store energy in liquid electrolytes. The electrolyte liquids for flow cells are usually metal salts in an aqueous solution that flow in two fully independent circuits. A special membrane positioned between them divides the cell into two half cells. The membrane prevents the two electrolyte liquids from mixing, but permits the exchange of ions. The electrolyte liquids in the two half cells are now pumped past the membrane, where the actual chemical reaction takes place in the form of reduction or oxidation, and energy is released.
Charging the nanoFlowcell® is not the same as for a regular flow battery through feeding it with energy, but through topping up the spent liquid electrolytes. In the nanoFlowcell® used in the QUANT models, the electrolyte tanks empty while driving and the spent electrolyte liquid is dispersed harmlessly into the atmosphere. Filling the tank of a QUANT model and the refuelling process itself is similar to that for a regular petrol or diesel vehicle.
Another aspect relevant to the environment is that nanoFlowcell® does not require rare and comparatively expensive substances - unlike conventional redox flow batteries. In contrast to conventional energy carriers such as petrol, diesel, hydrogen or lithium-ion batteries, the electrolyte liquids in the nanoFlowcell® are neither flammable nor explosive and are completely harmless to health.
In the first prototype of the QUANT model range, the QUANT E, the exceptionally powerful and compact nanoFlowcell® helped the sports saloon achieve acceleration of zero to 100 km/h in 2.8 seconds, a top speed of 380 km/h and a range of 600 kilometres [~375 miles]. In the current QUANT FE and QUANTiNO models, the range figures are considerably higher.
