Amazing hydrogen paste

---------- Forwarded message ---------
From: Larry Trout 

In Powerpaste form, it's completely stable at temperatures up to 250 °C (482 °F). It carries 10 times the energy of a similar weight in lithium batteries, and substantially more than a 700-bar H2 tank of the same weight. The researchers say vehicles running on a Powerpaste powertrain can expect a range "comparable to – or even greater than – gasoline."

When it comes time to release the energy, a plunger mechanism extrudes the paste into a chamber where it reacts with water to release hydrogen at a dynamically controlled rate, which then feeds a fuel cell to create electrical power with which to run an EV powertrain or other device. Part of the paste's impressive energy density comes from the fact that half of the hydrogen released comes from the water it reacts with.

I wonder about the cost.
