The barrier to solar energy
has always been storage.
Now, bottled sunshine
has a shelf-life of 18 years...
"In the last year, a team from Chalmers University of Technology, Sweden, essentially figured out how to bottle solar energy (Macroscopic Heat release in a Molecular Solar Thermal Energy Storage System).
They developed a liquid fuel containing the compound norbornadiene that - when struck by sunlight - rearranges its carbon, hydrogen, and nitrogen atoms into an energy-storing isomer,quadricyclane.
Quadricyclane holds onto the energy, estimated to be up to 250 watt-hours of energy per kilogram, even after it cools and for an extended period of time. For use, it's passed through a cobalt-based catalyst, at which point the energy is released as heat."
