Hydrogen may prove to be the fuel of the future in powering the effi cient, eco-friendly fuel cell vehicles of tomorrow. Developing a method to safely store, dispense and easily “refuel” the vehicle’s storage material with hydrogen has baffl ed researchers for years. However, a new and attractive storage medium being developed by Pacific Northwest National Laboratory scientists may provide the “power of pellets” to fuel future transportation needs.
