ABERDEEN PROVING GROUND,Md (June19, 2018) – The U.S. Army Research Laboratory plans to license its discovery of a nanogalvanic aluminum powder for hydrogen generation.

Army scientists have actually established an unique, structurally-stable, aluminum- based nanogalvanic alloy powder that, when integrated with water or any water-based liquid, responds to produce on-demand hydrogen for power generation without a driver.

“This powder-based alloy includes material that disrupts the formation of an encapsulating aluminum oxide layer, allowing for the continuous production of hydrogen that can be used at the point of need to power a wide range of devices via fuel cells and internal combustion,” statedDr Anit Giri, a researcher with the laboratory’s Weapons and Materials ResearchDirectorate “The powder can be easily manufactured to scale, and can be conveniently and safely transported via tablets or vacuum pouches, thus eliminating reliance on high-pressure hydrogen cylinders.”

ARL will be publishing a Federal Register Notice and releasing a supporting site welcoming business to send their concepts on how finest to advertise thistechnology The lab will then choose the most suitable partners and partners. Officials stated license exclusivity will then be identified.

“The Federal Register announcement is a significant step forward in the transition of power to the Soldier in the field, where it will become available on-demand at the point of need,”Dowding stated.

Researchers stated the powder has numerous benefits, such as:

  • Stable Alloy Powder .
  • Non-Toxic .
  • Environmentally Friendly .
  • Hydrogen Emitting .
  • Manufacture to Scale .
  • Easily Transportable

Army scientists found the distinct residential or commercial properties of the nanopowder while examining aluminum alloy structures for other functions. The scientists, from the laboratory’s Lightweight and Specialty Metals Branch, made the serendipitous discovery that a minimum of among these structures can, in the existence of water, spontaneously produce hydrogen, quickly and effectively.

“The researchers have since demonstrated rapid hydrogen generation rates using powder and tablet forms of the alloy,” stated Branch Chief RobertDowding “The hydrogen has been shown to be useful for powering fuel cells and is expected to power internal combustion engines.”

The scientists are presently benefiting from the development by defining the hydrogen generation rates and pureness of the gas created, Dowding stated.

“They are also examining the effects of compositional changes to the alloy and systematic changes in the microstructure of the powders,” he stated.

Giri stated the discovery has numerous advantages and applications, such as easy production.

“The powder can be made using current manufacturing techniques from either pure or alloyed aluminum,” he stated. “The manufacturing process is easily scalable and it is also very fast – with a 75-percent theoretical hydrogen yield in one minute at standard temperature and pressure, and 100-percent theoretical yield in three minutes.”

The nanopowder is likewise incredibly effective. Giri stated 1kg of powder can produce 4.4 kWh of energy– sufficient to power 10 60- watt incandescent light bulbs for more than 7 hours or the comparable LED bulbs for over 50 hours.

The product can be in powder or tablet kind and be integrated with any offered water-based liquid to supply hydrogen as needed, at the point of requirement.

Thediscovery gets rid of dependence on high-pressure cylinders, Giri stated.

“It’s easy to transport and store via tablets or vacuum-sealed pouches with no inherent inhalation risk,” he stated. “The powder is also environmentally friendly. Its by-products are stable and non-toxic. Finally it’s a versatile hydrogen source with direct combustion for vehicular power, to use in fuel cells to power any electronic device, and could potentially be used in 3-D printing/additive manufacturing to create self-cannibalizing robots/drones.”

In order to support a much better understanding of the product, the lab developed a site to display information on the technology and an evaluation procedure that will culminate in the approving of a patent license( s) around September 2018.

On this site, visitors can register their interest to be gotten in touch with about more advancements, post basic concerns and download background technical details, along with design templates for all the needed files that will be utilized throughout the procedure.
