Siemens Energy has launched an initiative called the “Future of Storage” to offer energy storage solutions catered to customers’ needs.

The initiative, which was announced last week, aims to bundle knowledge in order to design and build a new ecosystem of technology partners which will help the company to develop efficient, climate-friendly energy storage solutions.

Energy storage solutions are known to help comprehensive for the fluctuating feed-in of renewable energies and also have a big part to play in helping stabilise grids which enable them to hold the title of being one of the most important drivers of decarbonisation.

A global team of experts are being formed as we speak which will cover all areas of energy storage technologies. These include thermo-mechanical, thermal and battery storage systems.

Siemens Energy’s Anette Ossege-Schaffrath stated: “We want to offer every customer the optimal energy storage solution that best suits their needs.

“To do this, we need access to a broad portfolio of storage technologies. We need to have the necessary expertise and develop suitable business models. With Future of Storage, we are creating an important prerequisite for achieving these goals”

Following on from this, Jorn Schmucker, the CEO of Rotating Equipment at Siemens Energy, added: “Energy storage is the key to a decarbonised world.

“With Future of Storage and our partner ecosystem, we will be able to offer our customers exactly the solutions that fit their needs – with the advantage of improving the efficiency and thus the profitability of their plants.“

The launch of the Future of Storage initiative highlights Siemens Energy’s long-term partnership with Norwegian technology company EnergyNest.

The partnership aims to offer modularised and standardised thermal energy storage solutions for industrial customers.

The aim of the partnership is to jointly offer modularised and standardised thermal energy storage systems for industrial customers.

EnergyNest has developed a heat battery that’s able to be charged by either using renewable energy or with waste heat and can discharge completely renewable steam directly into customers’ plants when required. This reduces the demand for fossil generated heat and at the same time increases the flexibility of the plants.

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.
