A future powered by hydrogen fuel, whose only byproduct is water, has long been an eco-friendly dream too difficult to realize. Storing and transporting hydrogen can be difficult and dangerous, and hydrogen production methods can also produce unwanted carbon dioxide. A new catalyst promises to solve these problems, using CO2 and hydrogen to store energy in liquid form. The only thing you need to worry about is pH.
Science under pressure can produce marvelous results, such as an entirely new way to store hydrogen fuel. Researchers combined the noble gas xenon with molecular hydrogen (H2) to make a never-before-seen solid that opens the doors to an entire new family of materials for hydrogen storage.
When General Motors rolled out its "skateboard" vision for a fuel cell car at the 2002 Detroit auto show in January, there was buzz, and there was a big question. The skateboard concept, called Auto-nomy, was the product of GM's Design and Technology Fusion Group, and it radically reordered automobile physiology: Fuel cells, hydrogen, motor, and brakes were all crammed into a 15-foot-long, 6-inch-thick chassis onto which modular car bodies could be snapped. Drive-by-wire controls would plug into the skateboard's computer brain through a docking port.
