Light-weight Alloy Promises Improved Hydrogen Storage

Driving four hundred kilometres with a Toyota Prius, for instance, would require 317Kg of modern lithium batteries. With the new alloy, the same distance need a hydrogen tank of only 200Kg.

One of the biggest obstacles to using clean-burning hydrogen in cars and fuel cells is finding a way to safely and conveniently store the explosive gas.

New research by VU University Amsterdam has shown that one of the best storage media may be a lightweight alloy of magnesium, titanium and nickel.

A decade ago, researchers at the VU discovered that certain materials lose their reflection by absorbing hydrogen.


The Cadillac Provoq fuel cell concept uses GM's E-Flex propulsion system, combining the new fifth-generation fuel cell system and a lithium-ion battery to produce an electrically driven vehicle that uses no petroleum and has no emission other than water.

Powered by a 100 kW electric engine and fuel cell stack, the i-Blue is capable of running more than 370 miles per refueling and achieves a maximum speed of more than 100 miles per hour.

Based on the full-size 2007 Chevrolet Silverado 1500 HD pickup truck, the vehicle underwent extensive internal modifications to meet the technical demands and requirements needed to run on a compressed hydrogen fuel system.
