Hyundai Motor will showcase what it calls the world's first production fuel-cell electric vehicles at this week's Paris auto show.

After years of lagging behind the competition in battery technology, the South Korean automaker is betting on fuel-cell electric vehicles (FCEVs), which can run five times as long as E.V.s minus the hours of charge time. The cars, which convert hydrogen and oxygen into water and generating power to drive an electric motor, are a more realistic technology, according to Hyundai.

The greatest challenge the automaker faces now are production costs, which can run two to three times as much as traditional E.V.s—not to mention the lack of refueling infrastructure.

As the company wrangles with production costs, it will start out by just offering 1,000 FCEVs from December through to 2015 in Europe at an initial price of around $88,000...eek.

"We aim to reduce prices of fuel-cell vehicles to match battery cars by 2020-25," Lim Tae-won, the director in charge of fuel-cell research at Hyundai and its affiliate Kia Motors, told Reuters ahead of the Paris auto show.

Although studies have predicted the number of FCEVs will see a significant increase in upcoming years, demand will ultimately depend on customer acceptance of the technology and the availability of hydrogen fueling stations. Linde, a German industrial gases producer, will invest tens of millions of euros with Daimler to construct some 20 stations by 2015.

Will fuel-cells become the leading alternative fuel technology? Possibly, says Liam. Even though E.V.s have the upper hand now, he believes battery powered electric cars may have entered the market too early without resolving range anxiety and costs issues. Hyundai's FCEV can run up to 365 miles, while Nissan's Leaf can only run up to 73 miles on a full charge.

Until costs and infrastructure can catch up, however, it appears that E.V.s will still have a valid position in the marketplace for many years ahead. Like wind and solar in the global renewable energy portfolio, cleaner vehicle technologies will all likely develop a strong position in the market. From fuel-cells to electric cars and natural-gas powered vehicles, it appears the landscape of transportation—much like energy—is taking an all-of-the-above approach.

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.
