Ammonia pellets deliver hydrogen to cars of tomorrow

摘要

While hydrogen may eventually be the fuel of choice for the automobile of tomorrow, there are still questions about techniques for safely storing and dispensing the fuel. Scientists at the Pacific Northwest National Laboratory (Richland, WA) are closer to answering those questions with a novel storage technology using small (240-mg) pellets of solid ammonia borane (AB) to hold relatively large quantities of hydrogen (0.51) in a very small volume.
