QuantumSphere to Tackle Lower-Cost Electrolysis

QuantumSphere, a manufacturer of nanoscale metals and alloys for applications in energy and other markets, is launching a research initiative to develop a low-cost, more efficient system for the electrolytic production of hydrogen from water.

QuantumSphere’s water electrolysis processes will alleviate the current dependence on platinum—used as electrodes in electrolysis units— by delivering 80% cheaper electrodes with increased surface area and activity while reducing the electrical potential that resists the water splitting process, according to the company.

Several companies are struggling to efficiently generate hydrogen by water electrolysis with poor results thus far as today’s processes use expensive platinum electrodes. The high cost of platinum leads to the use of electrodes that have a small surface area.

Our water electrolysis research will ultimately enable us to leverage the Company’s nanomaterials to produce cheap hydrogen using water and electricity. QuantumSphere’s electrodes use QSI-Nano metals and alloys that are ten times less expensive when compared to platinum, offering an orders-of-magnitude increase in surface area (due to nano-scale size) to provide low cost, energy-efficient processes and materials to generate hydrogen.

—Dr. Douglas Carpenter, Chief Scientific Officer, QuantumSphere

QuantumSphere will announce the results of its research in Q4 2006 with performance data comparing its system to baseline experiments with platinum electrodes.



Much much better idea than "HHO". I did a patent search on HHO and found it quite odd that they have a statement in the patent that indicates a FOSSIL FUEL is ignited in HHO (or was it with HHO?).

Turns out that most of the properties of HHO seem strangely similar to acetylene. You may just pour water in but that initiates a chemical reaction with calcium carbide or something similar to release the acetylene...

The "independent" lab researcher often cited as having reviewed HHO happens to be one of the filers of the patent. Very interesting yes?

If electrolysis were 100% efficient, Hydrogen would still be a bad deal. The amount of energy required to store the stuff in a reasonably compact form is off the charts. Leakage, explosion dangers are also tremendous.


Actually it's not off the charts Robert. Honda is planning on deliver the FCX Concept in 3-4 years...it delivers 350 miles of range on 5 kg of hydrogen. Because of the efficiency of the fuel cell vehicle, you don't need to store as much to travel a decent distance.

Incidently, the Honda Accord V6 shares similar dimensions of length, height, width, etc as the FCX Concept. It gets 354 miles of range on 17.1 gallons of gasoline.


Mass produce the FCX (as if that were even possible in the near term given the nature of a few key components) and you would be talking about a vehicle with the same range as the Honda Accord but you'd pay a price that is probably in the Honda NSX (Acura NSX) to Ferrari Maranello range.


My previous comment is the *Real* "Reality Check"

What's the problem with a high price H2 vehicle? The price will come down, or at least the "outdated" model's parts could find their way into an affordable vehicle. Ex: The five speed auto in the Chrysler 300 was top of the line Mercedes spec in 1997. Also, a Ferrari Maranello probably doesn't have much more range than an Accord and I would love to see said Ferrari do a 1/4 mile against the FCX. IF Honda builds this car it will NEED to be able to run to satisfy those who drop six figures on a car anyway. In case it's not obvious, those who spend more than $30,000 on a car really don't care about fuel economy (or at least have no business caring about such things).
