The Royal Australian Navy recently signed an agreement with the US Navy to explore the use of alternative fuels in a quest to reduce their dependency on foreign fossil fuels.

A Statement of Cooperation, signed by Australia’s Chief of Navy, Vice Admiral Ray Griggs, AO, CSC, RAN and the US Secretary for Navy, Ray Mabus, recognized the benefits of alternative fuels and the importance of the project in terms of national security.

The RAN’s Fleet Commander, Rear Admiral Tim Barrett, AM, CSC, RAN described the project as having enormous potential at the signing ceremony on board the US aircraft carrier USS Nimitz on July 19th.

“All of us have a responsibility to be more environmentally aware,” he said. “As things stand today, biofuel remains too costly to use across our fleet. However, this project could lead to a cheaper alternative fuel.”

The US Navy has embarked on an ambitious plan to deploy a fleet of warships powered by alternative fuels by 2016, deemed the 'Great Green Fleet.' The initiative has been touted as one of the most effective moves to jumpstart the use of renewable energy in the US military and reduce its dependence on fossil fuels, which would, in turn, have similar effects on the larger economy.

“We are too dependent on either potentially or actually volatile places on earth to get our energy,” Mabus said in an interview with Renewable Energy World. “Now we’re susceptible to supply shocks and even if we’ve got enough, we’re susceptible to price shocks... when the Libya situation started and the price of oil went up $40 a barrel, that was almost a billion dollars additional fuel bill for the U.S. Navy.”

Along with the Air Force and Army, the Navy has tested and certified a number of ships and warplanes as biofuel compatible to run on a drop-in blend of conventional oil and green fuel that does not require engine modifications. With over $500 million invested in the biofuels industry, the Navy hopes to cut its use of fossil fuels in half over the next decade.

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.
