Pumped Hydro Energy Storage

In public policy, there are many dog鈥檚 breakfasts presented as considered initiatives. Rarely, though, are we served up such a self-contradictory, irrational and generally talentless a dish as the new 鈥渆nergy intervention鈥 announced by South Australia鈥檚 Labor government on March 14.

Aimed at side-stepping conservative attacks over recent power cuts, the government鈥檚 plan makes some provision for storage back-up to underpin wind and solar. But mainly, the $550 million scheme consists of large-scale concessions to fossil fuel interests 鈥 in this case, the gas industry.

One outcome of last year's inquiry into the Morwell Mine fire in Victoria's Latrobe Valley was the discovery that the default plan for 鈥渞ehabilitating鈥 the mine would be to let it fill with water naturally, perhaps to become a recreational lake. The hitch: it would take more than a hundred years to fill naturally and the water quality would be terrible due to pollution from coal seams.
