Giner

Giner is packaging hydrogen in a paste to power fuel cells, eliminating the need for high-pressure hydrogen storage tanks. The power paste—a mix of magnesium and hydrogen stored in a cartridge—would trigger the release of hydrogen gas when water is added. The paste is not flammable or explosive. The team will also update the system’s fuel cell to operate at lower humidity, making the approach more versatile and lower volume, improving the overall energy density of the design.

Giner’s technology could catalyze the broad electrification of the aviation sector by developing exceptionally high-energy storage solutions. The paste would be easy to store and transport, could be shipped in regular containers, and would not require special handling procedures. The approach eliminates the need for a high-pressure storage tank, humidifier, and compressor, allowing for weight, cost, and space savings. The technology would deliver at least a 300% improvement in fuel cell life combined with cost reductions of around 30% at the stack level.
