Powerpaste packs clean hydrogen energy in a safe, convenient gray goopFraunhofer researchers have presented a magnesium-based "Powerpaste" that stores hydrogen energy at 10 times the density of a lithium battery, offering hydrogen fuel cell vehicles the ability to travel further than gasoline-powered ones, and refuel in minutes.
Sounds like another “flying car in every garage” vaporware. Batteries & NOW are better than “someday in the future”.
Ya, cool tech that can address one problem with hydrogen fuel cell electric vehicles. But this solution requires re-occurring energy to recycle and re-create the paste. There needs to be a cradle to grave and/or wells-to-wheels analysis on net efficiency, GHG impact and total cost of ownership.
Ya right!
This is neat technology, which could solve the hydrogen storage issue, but it doesn't begin to address the barriers to clean and energy efficient hydrogen production, which would be the first step to making this viable. I don't think we will be seeing this in wide spread use anytime soon, because it doesn't address the major issues in producing and using hydrogen as a fuel.
For my anticipated use, that would mean refueling about every 6-7 months, or even less with maximum solar capacity and (limited) North Coast solar exposure.
