Energy storage system at The Hold in Suffolk
Connected Energy is set to install the E-STOR second life energy storage system at The Hold facility, on the University of Suffolk’s Ipswich campus...

The E-STOR will make energy use on the campus more efficient. Its system, which includes EV chargers, a critical HVAC and a PV, will form a controlled environment for archived materials, including those owned by Suffolk County Council.

Connected Energy’s CEO, Matthew Lumsden, said that the company’s position as an innovator in the second life battery market made its work at The Hold in Suffolk all the more difficult: “Leading the charge on the use of second life batteries meant we had to start developing systems based on a relatively small data set. But having run several systems though various duty cycles over the last few years we are now able to further optimise how the batteries are operated”.

Mr Lumsden also spoke about the energy advantages of using second life batteries over lithium ion ones: “Second life systems can have different objectives. The cost of the batteries is lower than for new lithium ion systems, so the degradation and overall cycle cost is lower. This means that duty cycles that are uneconomic for new systems can be viable for second life systems. The data-based design that has now been undertaken means we can more accurately optimise how the batteries are used within any duty cycle and better manage efficiencies and degradation.”

A representative of Suffolk County Council, Cllr Paul West, a cabinet member with responsibility for Heritage, commented that the new energy storage system will help the council to meet its objectives: “This work builds on Suffolk County Council’s own knowledge base on the operation of energy storage systems across its estate. It is also a significant move in driving down our carbon emissions, as the council aims to lead by example and be a net zero organisation by 2030, following our climate emergency declaration in 201

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
