New methods and compositions are disclosed that minimize foaming in hydrogen-releasing materials. Foaming can be minimized during release of hydrogen in composites that include structured forms such as wafers and discs. Change tolerances of from 0% to 25% in solid products described show promise for next-generation fuel elements and devices.
