Ethylene, a ho-hum material that is the building block of the most common plastic, might have an exciting future in storing hydrogen, the hoped-for transportation fuel of the future. New research reported by scientists from the National Institute of Standards and Technology and Turkey’s Bilkent University makes the surprising prediction that “ethylene, a well-known inexpensive molecule, can be an important basis in developing frameworks for efficient and safe hydrogen-storage media.”
