How can individuals store such a large amount of terawatt hours without the infrastructure to support it?
How does a unit of dissident currency work?
I mentioned batteries because industries and people want to store available energy and transmit it on demand. I can envisage a system that uses commodities such as electricity and other energy generation assets as a means of deferring consumption and paying with electricity on demand as an alternative form of settlement.
However, I only see it working on closing loops, because coordinating different jurisdictions is extremely difficult.
