La sociéte Gildemeister en Autriche qui avait faillite en Novembre 2017 est reprise par la société canadienne Stina Resources.
La production de batterie à flux Vanadium va pouvoir reprendre.

Austrian vanadium flow battery technology in new ownership

April 04, 2018 // By Nick Flaherty

Stina Resources of Toronto, Canada, expects to finish buying the assets of Austrian flow battery pioneer Gildemeister in the next few days and re-start selling batteries as Enerox.

Gildemeister was one of the world's first and largest researchers, developers, manufacturers and distributors of vanadium flow batteries with over 100 flow batteries installed at sites around the world but went bankrupt in November 2017.

Sina has set up an Austrian subsidiary called Enerox GmbH in Vienna, and the Austrian receiver has transferred all the operational functions to the new company on April 1, 2018. This includes employee contracts, rental agreements, and all related contractual obligations. The company owns 19 patent families on flow battery technology, including 40 granted patents and key IP on plug-and-play flow battery technologies.

Stina expects the deal to close on or about April 11, 2018, when Enerox will be able to resume full production and sales of CellCube vanadium flow batteries.

"Enerox CellCube is one of a few proven technologies on all scales and sizes of vanadium flow battery storage requirements. Gildemeister had over 100 installations worldwide. We are on the threshold of an immense opportunity as the world embraces green energy and develops the efficient means to store it. We want Stina and Enerox to be the green energy solution," said Brian Stecyk, President and CEO of Stina.

CellCube batteries are non-flammable and non-explosive and can store megawatts or even gigawatts of energy with plug-and-play capacity that can be increased just by adding another unit. The batteries have over 20,000 cycles, last a minimum of 20 years and some that have been operating for over 10 years have never required servicing.

The vanadium flow batteries are currently operating in a broad range of climates including in Siberia, Africa, South East Asia, Europe, North America, and Australia. They can operate in all conditions—from extreme cold to dry deserts and extreme tropical environments.

"Since Stina began this process several months ago, we have received a tremendous number of queries about vanadium flow batteries, particularly in North America. The interest is continuing to grow as the world learns more about the benefits of vanadium flow batteries. The installations include applications such as: solar power storage, wind power storage, micro-grid uses; grid peak shaving and load leveling; diesel replacement; standby battery power in hurricane areas; electric car charging facilities and many other uses. The consensus at a recent battery technology conference in Dusseldorf, Germany was that the pioneering years are over and battery storage is now a normative part of the energy world," said Stecyk.
"The recent announcement by Saudi Arabia and Softbank to develop a $200 billion solar project in Saudi Arabiaconfirms our belief about the future of renewable energy and the storage industry. We believe this is just the tip of the iceberg," added Stecyk.

Une ''petite'' batterie à flow redox au Vanadium mise en service en Espagne pour su stockage stationnaire d' ENR. Puissance 120 kW , et 400 KWh de réserves.
Siemens Gamesa tests redox flow battery at its La Plana test site in Spain

May 23, 2018 evwind

Hybrid projects combined of wind-energy, solar PV and other energy sources are becoming a more and more attractive option to drive the energy transition to higher shares of renewable energy in the mix. Siemens Gamesa is one of the pioneers in this development with a long term track record in hybridization and off-grid technology. Now the company has taken another important step and is testing a battery storage technology with large future potential. At SGRE’s La Plana R&D site near Zaragoza, Spain, a redox flow energy storage system has been commissioned. The system is connected to the hybrid controller of the combined wind and PV generation system and supplements the lithium-ion batteries that have been in use here for around two years.

The La Plana test-site integrates the next-generation Vanadium redox energy storage system with a wind turbine, solar-PV modules and a diesel generator. The new redox flow battery offers a 120kW energy output with a storage capacity of 400kWh. Siemens Gamesa has been refining its knowledge in hybridization over years. A sophisticated flexible hybrid controller is the resulting product of this R&D effort. It is the digital core that coordinates the generation of all energy sources to meet the electrical load, in order to reduce the LCoE of the plant regardless of whether the grid is connected or disconnected. To reduce energy costs the controller is targeting to achieve the maximum integration of renewable energy.

To support the highly efficient dispatch strategy steered by intelligent control algorithms a large storage capacity helps to keep generators to their technical minimum load and to enhance the share of renewables – even when low wind periods and cloudy sky occur at the same time.

“With the Redox-Flow technology commissioned at our La Plana test site, we are now active in all relevant storage technologies including Power-to-Heat and also battery storage systems,” says Antonio de la Torre, SGRE’s chief technology officer. “Due to its scalable energy capacity the Vanadium redox battery is a highly promising option to support our advanced technology offers for isolated and grid connected systems”.

L' analyste IDTechEx anticipe une progression fulgurante des batteries à flux redox d'ici 2031 :
Competition between redox flow, li-ion batteries to heat up over next decade – report

MINING.COM Staff Writer | May 30, 2021 |

A report by IDTechEx states that redox flow battery technology might start to gain field to lithium-ion batteries over the next decade, overtaking the Li-ion battery energy capacity installed by 2031.

By relying on a vanadium, zinc-polyiodide, polysulfide bromide or uranium electrolyte solution held in storage tanks, redox flow batteries can store energy from renewable sources, including solar, wind or wave power, and release it when required.

Image

IDTechEx’s forecast for this energy storage system is based on the fact that the energy scenario is changing as a result of years of green policies adopted by a growing number of countries, with energy storage playing a key role toward the integration of variable renewable energy (VRE) in the power grid.

“The large adoption of variable renewable energy is substantially affecting the grid infrastructure, and more renewables will be installed, so the necessity to adjust and update the power grid will be greater. In fact, variability is one of the issues faced by the power grid,” the report reads. “The advent of VRE implies a variation of the existing grid infrastructure, due to the nature of renewable energy, both wind and solar. The variable and uncertainty of these renewable energy sources exacerbate the flexibility issue of the existing power plant.”

According to IDTechEx, flexibility is defined as the ability of the power system to deal with a higher degree of uncertainty and variability in the supply-demand balance, a characteristic that has existed in power systems from well before the advent of low-cost VRE. However, the market analyst believes that the evolution of its definitions has undoubtedly been driven by the increased adoption of VRE.

Given the need for a steady supply of power that does not stop due to the intermittent nature of the wind and the sun, the researcher says that it foresees a large adoption of redox flow batteries toward the end of the next decade, once the RFB sector gets a solid position on the market, overcoming the strong competition from the well-established Li-ion battery systems.

Redox flow battery market expected to become multi-billion by 2031 – report

MINING.COM Staff Writer | July 15, 2021

A new report by IDTechEx states that the current trend of adoption of redox flow batteries (RFBs) should lead to a multi-billion market size in 2031.

However, in the analyst’s view, this massive adoption doesn’t imply that lithium- ion (li-ion) batteries will disappear. Rather, the two systems are expected to address different issues.

...................
https://www.mining.com/redox-flow-batte ... 31-report/

ils parlent de batteries à flux basé sur le fer au lieu du Vanadium. J'avais pas encore entendu parler de ça. :-k
According to IDTechEx, VRFBs are likely to find their biggest competitor in iron flow batteries (IRFBs), especially in the large-scale stationary market.

For the market researcher, the IRFB is an interesting candidate for large-scale applications due to the low cost of iron, which leads to a reduced capital cost.

IRFBs also offer the possibility to easily recycle the electrolyte and avoid cost fluctuation of the electroactive material, as it might happen to vanadium.

Recent studies have also shown that IRFB production may be less polluting than the manufacturing of VRFBs.

“Although the IRFB will likely compete for large-scale applications with VRFB, the two technologies will bring to the market a different quality of storage system. This will in turn allow a larger variety of products for the customer,” the report reads.

New all-iron redox flow battery for renewables storage
Scientists in the U.S. claim to have demonstrated an inexpensive, long-life, safe and eco-friendly redox flow battery. The device is said offer coulombic efficiency of 97.9% thanks to functional electrolyte additives, pH and elevated temperature.

JULY 22, 2020 EMILIANO BELLINI

Researchers at the Dornsife College of Letters, Arts and Sciences of the University of Southern California (USC) have demonstrated a new all-iron redox flow battery for renewable energy storage they claim is inexpensive, safe and eco-friendly as well as offering a long lifetime.

Presented in the study Improvements to the Coulombic Efficiency of the Iron Electrode for an All-Iron Redox-Flow Battery, published in the Journal of The Electrochemical Society, the device is said to have demonstrated coulombic efficiency – the ratio of charge extracted against charge put in over a cycle – of 97.9%, thanks to functional electrolyte additives, pH and elevated temperature.

The researchers say that level of efficiency is among the best recorded for charge and discharge of an iron electrode. “The coulombic efficiency during electrodeposition of iron was found to improve with increasing pH at all values of current density,” stated the USC group. “We have found that ascorbic acid has an important role in determining the coulombic efficiency.”

Hydrogen problem

The researchers claim to have addressed the problem of parasitic evolution of hydrogen at the iron electrode during battery charging, which causes a drastic reduction in performance of redox flow batteries and occurs as a significant side reaction in devices featuring acidic electrolytes. “Hydrogen evolution affects the repeated cycling of the redox-flow cell by rapidly changing the composition of the electrolyte in the system,” the researchers said.

Adsorption of ascorbic acid added to the electrolyte is said to have inhibited hydrogen evolution at zero pH and elevation of the pH value near the surface of the electrode raised coulombic efficiency during iron electrodeposition. Ascorbic acid was used as an electrolyte additive in iron plating to minimize the air oxidation of iron – which prevents the kinetics of hydrogen evolution – in combination with an increase in pH. The electrolyte solution was developed with iron(II) chloride and ammonium chloride. “While the two compounds are well known individually, it’s the first time they’ve been combined to prove their potential for large scale energy storage,” said the USC group.

Cadmium

The academics said hydrogen evolution could be further inhibited if a second metal, such as cadmium, which is not exactly an eco-friendly material, is co-deposited with iron and becomes immiscible with it. “This will ensure that the second metal remains on the surface at all times and does not diffuse into the bulk of the iron electrode,” stated the group. “By staying on the surface, the second metal will continue to provide the suppression of hydrogen evolution during the entire course of electrodeposition.”

The researchers found battery efficiency rose as the device’s operating temperature did. “We observed a coulombic efficiency of 97.9% at 60 degrees Celsius compared to 91.8% at 25 degrees Celsius,” said the scientists.

“With the fundamental insights gained in this study, and the improvements in coulombic efficiency demonstrated, we believe that the all-iron redox flow battery based on iron chloride will continue to present an attractive pathway for large scale electrical energy storage and the authors believe that the future will benefit from research on approaches to achieving 100% coulombic efficiency,” stated the group.

VRB begins construction on 100MWh vanadium flow battery project in China

By NS Energy Staff Writer 01 Sep 202

The energy storage project in Xiangyang will be paired with 1GW of new wind and solar PV projects

Canada-based VRB Energy has officially started the construction on a 100MW/500MWh vanadium flow battery energy storage project in Hubei Province, China.

The energy storage project in Xiangyang will be paired with 1GW of new wind and solar photovoltaic (PV) power generation projects.

The total investment of all the facilities is C$1.81bn ($1.44bn), said Sparton Resources, which holds a stake of 9.8% in VRB Energy, through its subsidiary VanSpar Mining.

The vanadium flow battery integrated power station project is being implemented by the Hubei Province and the State Power Investment Group through Hubei Green-Move Zhongvan New Energy (Green Move ZF).

The project is part of China’s national “Carbon Neutral and Carbon Peak Strategy”.

According to Sparton Resources, an investment of C$841m ($668m) will be made for constructing the initial 100MWh all-vanadium redox flow battery energy storage power station as well as 500MW of distributed rooftop PV installations.

The power station for the project will be built in the Automobile Industrial Park of the Xiangyang High-tech Development Zone. To be spread over 8ha, the power station is expected to be commissioned officially for operation by the end of next year.

VRB Energy CEO Huang Mianyan said: “The opening ceremony marks the official construction stage of the 100MWh all-vanadium flow battery energy storage project, which will accelerate the promotion of energy storage using vanadium flow battery energy systems in Hubei.

“The application of our new technology has laid a solid foundation for new business. VRB Energy has participated since 2019, in the construction of the first phase of the 3MW + 3MW/12MWh vanadium redox flow battery energy storage phase of the 10MW solar and storage project in Hubei Zaoyang, and the project is working well.”

VRB Energy’s vanadium redox battery systems are designed to store energy in liquid electrolyte by using a process based on the reduction and oxidation of ionic forms of vanadium.

In July 2021, the company secured an investment of $24m from BCPG, a Thailand-based renewable energy developer.

Chinese Firms to Promote Vanadium Energy Storage

14 Sep 2021 by argusmedia.com

Major Chinese titanium and vanadium producer Pangang Group Vanadium/Titanium Resources and the world's largest producer of high-purity vanadium products and vanadium electrolyte Dalian Borong New Materials (BNM) will jointly promote the commercialisation of vanadium redox flow battery (VRFB) energy storage.

The agreement, signed on 10 September, marks Pangang's entry into the energy storage industry, which will accelerate comprehensive utilisation of vanadium resources in the Panzhihua region and promote the upgrading of the vanadium industry.

China's aim to accelerate a transition to lower energy consumption and to stimulate demand for renewable energy and energy storage products during its 14th five-year economic plan for 2021-25 has prompted many companies to develop new VRFB projects. VRFBs have a much larger energy storage capacity than lithium batteries. It is more effective for China's plans to achieve its target of peak carbon emissions by 2030 and carbon neutrality by 2060, according to market participants. China aims to install 120GW of new wind and solar power generation capacity in 2021.

The firm has also expanded its layout in the vanadium industry recently. It acquired 100pc equity of Xichang Vanadium Products Technology on 6 August, which is expected to double its vanadium output after the acquisition.

The firm on 4 September signed a cooperation framework agreement with key domestic vanadium flake supplier Sichuan Desheng to set up a joint venture focusing on processing vanadium slag. Pangang will contribute 65-70pc of cash capital, while the remainder will come from Sichuan Desheng. The joint venture will build a vanadium slag processing facility with 20,000 t/yr vanadium pentoxide equivalent of capacity.

Market participants estimate around 9.25t of vanadium pentoxide is used in each MWh of vanadium storage battery. China is expected to install around 30-60GWh of new energy storage capacity by 2030, corresponding to 28,000-56,000 t/yr of extra demand for vanadium pentoxide during 2021-2030.

BNM develops and produces high performance vanadium products. Its full product range includes vanadium oxides, vanadium compounds and vanadium electrolyte, which have applications in aerospace, energy, chemical industry and other emerging markets.

Dalian Rongke Power, a service provider for vanadium redox flow batteries, has connected the world’s largest redox flow battery energy storage station to the grid, in Dalian, in China's Liaoning province.

The station is expected to start operations in mid-October, following its approval by the Chinese National Energy Administration in 2016. The technology was developed by the Dalian Institute of Chemical Physics (DICP), under the Chinese Academy of Sciences.

The first phase of the project has a capacity of 100 MW/400 MWh, for an investment of about CNY 1.9 billion ($266 million). The second phase of the project is expected to push the full capacity to 200 MW/800 MWh. That will bring the total investment to CNY 3.8 billion, according to the Chinese Energy Storge Alliance.

The Dalian Flow Battery Energy Storage Peak-shaving Power Station will perform peak shaving and valley-filling grid auxiliary services, to offset the variability of the city’s solar and wind energy supply. Solar and wind will be used to charge the station's batteries during the grid load valley period by converting electrical energy into battery-stored chemical energy. Later, at peak grid load, the stored chemical energy will be converted back into electrical energy and transmitted to users.
