The July edition of Scientific American has an add by ECD on page 87
It is next to a series of articles on Fuel Cells. It highlights two of ECD's fuel cell related technologies. NiMH batteries and in the lower half Ovonic Metal Hydride (MH) Storage devices

The storage devices is a cylinder containing an Ovonic Alloy offering
Hydrogen storage in a solid state of 5%wt to 7% wt at 300 degrees C
desorption(opposite of absorption) equivalant to 560 to 780 standard liters per kilogram of alloy.


excellent desorption kinetics initiated within a few seconds

Life of over 2000 cycles

Poison tolerance especially to CO

Ovonic MH storage systems can provide pure H2 to fuel cells or ICE

Ovonic MH storage systems are safe compact low pressure hi density alternatives to gaseous or liquid H2 storage at lower cost.

My take
In the surrounding articles Metal hydride storage is discussed at 2%
This Ovonic storage is superior to earlier forms. ECD recently received a
patent on Magnesium storage. From back of the envelope calcs in my case a very old envelope a business envelope and not an engineering envelope. 64 kilos will hold the amount discussed in the article sufficient for 36000 liters enough for 500 kilometers driving.
