At the University of California, engineers created ceramic materials to increase and ensure hydrogen storage safely. This was part of a 1.2 million dollar project.Mixtures of calcium hexaboride, barium hexaboride, and strontium were used to make this. Combustion synthesis was the cheap process involved. Combustion synthesis is an attractive technique to synthesize a wide variety of advanced materials including powders and near-net shape products of ceramics, intermetallics, composites, and functionally graded materials.
They were looking solid materials that can store and release hydrogen easily.
