A New Contender for High-Density Energy Storage...

An interesting new development from Washington State University.  Their scheme is a compression system, akin to the compressed-air storage systems, but on a molecular level with a vastly higher ratio between uncompressed and compressed states.

There are a few challenges to be overcome, however.  First, the required compression currently can only be achieved in a laboratory diamond anvil compressor – which can only compress tiny quantities at a time.  Secondly, the material used in the system is xenon difluoride (XeF2), a powerful chemical agent that's dangerous to handle.  Despite the challenges, there are possibilities here...
