Pumped Hydro Energy Storage

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

Aimed at side-stepping conservative attacks over recent power cuts, the government’s 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 — 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 “rehabilitating” 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.
