On the assumption that hydrogen-powered cars (jet packs?) will be commonplace some day, H-hawker Horizon introduced a consumer gadget at CES that converts water into hydrogen and stores it safely in solid form.
The small desktop device simply plugs into the AC, a solar panel or a small wind turbine, automatically extracts hydrogen from its water tank and stores it in a solid form in small refillable cartridges. The cartridges contain metallic alloys that absorb hydrogen into their crystalline structure, and release it back at low pressures, removing concerns about storing hydrogen at high pressure. This storage method also creates the highest volumetric energy density of any form of hydrogen storage, even higher than liquid hydrogen. Unlike conventional batteries, these cartridges carry more energy capacity, are cheaper, and do not contain any environmentally-harmful heavy metals.
Horizon believes the HYDROFILL is the first step towards private refueling of new generations of fuel cell electric vehicles. Fuel cell technology can greatly improve the features and usability of many battery or engine-powered devices, and create the possibility for lower cost electric cars that drive longer distances and recharge instantly.
