Dr Matthew Stocks, from the ANU’s Energy Change Institute, spoke to the meeting about Australia’s 100% renewable energy future, focusing on pumped hydro. Together with photovoltaic cells and wind generators, a stable and affordable electricity grid is readily achievable.
Matthew’s presentation added a lot of context and clarity to a series of slides illustrating pumped hydro energy storage, from the Energy Change Institute’s website
[updated slides from the Global Pumped Hydro Energy Storage atlas here,
and most recently (October 2020) from Andrew Blakers’ “100% Renewables”, here].
