Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
This sounded great: using hydrogen to generate electricity without combustion. The exhaust is pure water. I was excited
Years after losing interest, I decided to check on recent developments in the field.
I discovered that research into the use of fuel cells is alive and well.
This may very well become the disruptive technology that we hope it could be.
Here are some of the many recent innovations out there:
April 9 2013: Burn scrap paper and aluminum, add cheap catalyst and water: "cheap" hydrogen on demand
Nov 25, 2013: CellEra creates a catalyst free of rare earth metals.
April 29, 2014: Lawrence Berkeley and Argonne National Labs create a process that uses 85% less platinum and has more the 30 times the catalytic activity.
June 24, 2014: UK's Science and Technology Facilities Council experiments with ammonia as a source fuel.
It is relatively easy to store, "cheap" to make, and can be stored at low preassure.
July 2014: GE has developed a process that uses stainless steel as a catalyst instead of platinum.
The fuel is natural gas instead of pure hydrogen. The exhaust, a mixture of hydrogen
and carbon, is then put through a combustion engine for further efficiency.
August 4, 2014: Anglo American Platinum is funding a study into the use of liquid organic hydrogen carrier (LOHC) technology
as a means of storing hydrogen.
August 22, 2014: Stanford has developed an process for producing hydrogen from water using inexpensive materials and relatively little energy."
