Nuclear option ‘not enough’ to avoid rush for more wind and solar

A massive expansion of renewable energy will still be key to driving Australia’s transition away from coal and reaching net-zero emissions by 2050, new modelling shows, even if the Coalition wins the next election and implements a plan to deploy nuclear reactors across the country.

Opposition Leader Peter Dutton rekindled Australia’s climate wars this month, vowing to abandon the government’s target for renewable energy to account for 82 per cent of the grid by 2030, and instead pushing to build seven nuclear generators to achieve the longer-term ambition of reaching net-zero emissions by 2050.

However, modelling from research group Bloomberg New Energy Finance raises questions about how beneficial it would be for Australia to adopt nuclear energy at a time when it faces an imminent wave of more coal-fired power station closures and significant power demand growth driven by electrification and decarbonisation.

Assuming the Coalition’s seven proposed nuclear reactors add 7 gigawatts of nuclear power capacity by 2050, the rollout would reduce the necessary build-out of solar farms by only up to 7 per cent and wind farms by 12 per cent, the analysis found.

Even doubling that to 14 gigawatts, nuclear was found to have a limited role in avoiding the need to hasten the shift to large-scale renewables and to build far more power lines to connect them to the grid and major cities, it said…………………………………………………………………….

n its 25-year road map released this week, AEMO says Australia’s best and lowest-cost pathway through the transition is to build a grid dominated by renewable energy, firmed by grid-scale batteries and backed up by gas-powered generators.

AEMO did not assess the costs of nuclear energy because nuclear energy is banned under federal law. But it said nuclear “is one of the most expensive ways to generate electricity” and it said building the plants “would be too slow to replace retiring coal-fired generation”.

Energy Minister Chris Bowen said the BloombergNEF report was “another example of experts confirming nuclear was too slow, too expensive and too risky for Australia”. https://www.smh.com.au/business/the-economy/nuclear-option-not-enough-to-avoid-rush-for-more-wind-and-solar-20240628-p5jpjk.html
