Can energy storage make renewables a viable substitute?

In order to make renewable energies a viable substitute for fossil fuel-based energy sources, we need to find a way to cope with the inherent intermittency.

A substantial storage capacity is needed to act as a buffer, ideally de-centralised.

Attending a presentation by Prof. Donald R. Sadoway from the Massachusetts Institute of Technology (MIT) introduced the idea of liquid metal batteries.

Current research looks very promising.
