Discovering Hydrogen Storage Materials

Aiming at using
hydrogen as an alternative fuel, GE is working with DOE to develop onboard hydrogen storage storage materials for automotive applications.

Li2Mg(NH)2, which contains 5.6% hydrogen and has reversible storage capability, has been the recent research focus. GE is using both synchrotron x-rays and neutrons to study the reaction pathways and crystal structures in unprecedented detail.
