develop Ammonia as a universal energy storage medium
Why do we need to develop new technology when we have 22000 identified sites for pumped hydro. These sites have potential storage capacity of 67,000 Gigawatt-hours of which we need about 450 GWh of storage.
At least Snowy 2.0 is heading in the right direction.
I am all for PV/Wind but we need to be realistic and build storage
at the same time as we build the PV/Wind generation.
Each PV/Wind generation and storage system needs to have sufficient generation and storage capacity to supply its rated output for at least 3 days if it is going to replace coal.
You don't replace a base load station which can operate 24/7 with an intermittent source the output of which is at the whim of the weather.
In the meantime we still need base load coal as does the rest of the world. Even the poster boy Germany. And it burns the worst possible form of fossil fuel to backup its renewables.
