ACCC bells the cat on electricity

By Graham Young - posted Monday, 16 July 2018


Given the issues with nuclear a sensible use of the resources being poured into "clean" energy should be redirected to researching nuclear power and handling spent nuclear fuel.

Australia is already a leader in one of these areas, having developed Synrock for safe storage of spent nuclear fuel in 1978.

An alternative to storage is reprocessing. As a country which already mines uranium and turns it into yellow cake we have advantages there as well.

While developing a nuclear program we need holding and bridging strategies to limit emissions. Efficiency is probably the lowest cost strategy, and an increased use of gas, which emits half as much CO2 as coal, another.

Finally we need to understand that storage will never be suitable for a large scale grid without repealing the Second Law of Thermodynamics – that's the one that put paid to perpetual motion machines.

Battery enthusiasts draw comparisons between computers and batteries and predict that, just as computers have dived in cost and soared in computing power, the same will happen to batteries and power output.

But computers have done this by miniaturising and using less power to do the same work. Batteries are all about producing energy, and only so much efficiency can be wrung out of this process.

A more realistic model for how much increased efficiency is available is the motor vehicle. While it is true to say that the modern car is a significant refinement on the Model T, that refinement is nothing like the one that occurred between a pioneering computer like ENIAC, and the laptop on which I am typing this article.

The only step change in energy production comparable to that in computing is contained in the equation e=mc2, where Einstein showed that changing a small amount of mass into energy released huge amounts of energy.

Which brings us back to nuclear.

While the ACCC report doesn't mention nuclear, it does open up the conversation. Politicians need to grab the opportunity. Otherwise they face a grinding political death between the stones of increasing electricity costs and decreasing reliability, all while CO2 emissions continue to rise.
