You've probably read that an hydrogen-based economy will emerge soon -- or in twenty years. But first, we need to find efficient ways to store hydrogen fuel. Now, chemists from the University of Michigan (U-M) have developed new materials made of rigid plastics that are at the same time lightweight, robust and economical. These new materials, called covalent organic frameworks (COFs), are made of light elements, such as hydrogen, boron, carbon, nitrogen and oxygen, and can be assembled to form predictable crystal structures -- something that never had been done with rigid plastics. So far, these materials are only available in labs. But read more for other details and references.
