Conventional approaches to compact hydrogen storage — compressing the gas to up to 10,000 pounds per square inch (psi) or cooling it down to cryogenic temperatures so that it liquefies (around 252 degrees Celsius)-- can attain only about half the energy density needed to fit enough fuel inside something the size of a gas tank.
These materials include new classes of superconductors, superhard materials, high - energy density and hydrogen storage materials, new ferroelectrics and magnetic systems, and materials that resist chemical changes under extreme conditions, said Russell Hemley, director of the Geophysical Lab and associate director of EFree.
The (sII) hydrate has been reported to meet current Department of Energy's target densities for an on - board hydrogen storage system.
The next FCEV from Hyundai Motor Group will have a driving range of 800 km, a maximum power output of 163PS, and the largest hydrogen storage density of any Fuel Cell vehicle on the market.
Onboard hydrogen (H2) storage, whether as a gas, liquid or chemically adsorbed in another material, enabled higher energy density than then - current batteries, giving an FCV significantly greater potential range than a comparable electric vehicle (EV).
Hydrogen produced via the water - splitting reaction (WSR)... is arguably the easiest to produce and stores the most energy on a mass basis (kJ / kg); however, it is not a particularly attractive replacement fuel for transportation, due to technological issues with low - volume energy density, safe storage, and transportation.
To their surprise, the titanium augmented sodium alanate's capabilities as a storage system - lowering the temperature at which hydrogen was released, making the process much more efficient, while allowing for easier refueling and storage of high - density hydrogen at more conventional pressures and temperatures.The result: a near - doubling of the stored gas» weight - percent when compared to other cheap materials.
