H2Rescue can drive up to 180 miles and provide power for 72 hours at a disaster site without refueling. H2Rescue accomplishes this by carrying a substantial amount of hydrogen—up to 176 kilograms at 700 bar. As a Class 7 heavy-duty truck that weighs approximately 33,000 pounds, H2Rescue can transport enough. . During the demonstration at NREL, the vehicle fueled up at NREL's hydrogen fueling station, drove to the Flatirons Campus near Boulder,. . To accelerate the integration of hydrogen in the clean energy economy, the White House released the U.S. National Clean Hydrogen Strategy and Roadmap, a comprehensive framework. [pdf]

Photo: A typical modern flywheel doesn't even look like a wheel! It consists of a spinning carbon-fiber cylinder mounted inside a very sturdy container, which is designed to stop any high-speed fragments if the rotor should break. Flywheels like this have an electric motor and/or generatorattached, which stores the. . Flywheels are relatively simple technology withlots of plus points compared to rivals such as rechargeable batteries: in terms of initial cost and ongoingmaintenance, they work out cheaper, last. . In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. [pdf]
