Nuclear Power Should Be Allowed But Only With A Carbon Price

Looking at the state of policy on energy and climate change in Australia, it’s tempting to give in to despair. At the national level, following the abandonment of the National Energy Guarantee last year, we have no coherent energy policy and no serious policy to address climate change.

In this context, the announcement of two separate inquiries into the feasibility of nuclear power (by the New South Wales and federal parliaments) could reasonably give rise to cynicism. The only possible case for considering nuclear power, in my view, is that it might provide a way to decarbonise our electricity supply industry.

Yet many of the keenest boosters of nuclear power have consistently opposed any serious measure to address climate change, and quite a few have rejected mainstream science altogether.

Yet in a situation which all responsible people view as a climate emergency, we can’t afford the luxury of despair. For this reason, rather than dismissing these inquiries as political stunts, I made a submission to the federal inquiry setting out the conditions required to allow for any possibility of nuclear power in Australia.

The submission was picked up by the national media, which largely focused on my proposal to lift the state ban on nuclear power and implement a carbon price.

The reception from commentators on the right, who want the ban lifted, and from renewables advocates, who want a price on carbon, suggests a middle ground on nuclear power may be achievable.

The three big problems with nuclear power

Three fundamental problems arise immediately when considering the prospect of nuclear power in Australia. First, the technology is expensive: more expensive than new fossil-fuelled power stations, and far too expensive to compete with existing fossil fuel generators under current market conditions.

Second, given the time lags involved, any substantial contribution from nuclear power in Australia won’t be available until well beyond 2030.

Third, given the strong public opposition to nuclear power, particularly from the environmental movement, any attempt to promote nuclear power at the expense of renewables would never get broad support. In these circumstances, any investor in nuclear power would face the prospect of losing their money the moment the balance of political power shifted.

On the first point, we have some evidence from the contract agreed by the UK government in for the construction of the Hinkley C nuclear power plant. This was the first new nuclear construction project to be approved in an OECD country for a number of years.

The agreement to construct Hinkley was based on a guaranteed “strike price” of £92.50/ megawatt hours (MWh), in 2012 prices, to be adjusted in line with the consumer price index during the construction period and over the subsequent 35-year tariff period. At current exchange rates, this price corresponds to approximately A$165.

Prices in Australia’s National Electricity Market have generally averaged around A$90/MWh. This implies that, if new nuclear power is to compete with existing fossil fuel generators, a carbon price must impose a cost of A$75/MWh on fossil fuel generation.

Assuming emission rates of 1.3 tonnes/MWh for brown coal, 1 tonne/MWh for black and 0.5 tonnes for gas, the implied carbon price ranges from A$50/tonne (to displace brown coal) to $150/tonne (to displace gas). On the basis that nuclear power is most plausible as a competitor for baseload generation from brown coal, I considered a price of A$50/tonne.

A blueprint for reform

The central recommendations of my submission were as follows:

Nuclear Power Should Be Allowed But Only With A Carbon Price Nuclear power, while costly, could dramatically reduce Australia’s electricity sector emissions. AAP

Recommendation 1: A carbon price of A$25/tonne should be introduced immediately, and increased at a real rate of 5% a year, reaching A$50/tonne by 2035.

Recommendation 2: The government should immediately adopt the recommendations of its own Climate Change Authority for a 40% to 60% reduction in emissions by 2030, relative to 2000 levels, and match other leading OECD countries in committing to complete decarbonisation of the economy by 2050.

Recommendation 3: The parliament should pass a motion:

  • affirming its confidence in mainstream climate science and its acceptance of the key conclusions of the United Nations’ Intergovernmental Panel on Climate Change;
  • legislating a commitment to emissions reductions;
  • removing the existing ban on nuclear power.

Let’s all meet in the middle

Rather to my surprise, this proposal received a favourable reception from a number of centre-right commentators.

Reaction from renewables proponents, on social media at least, was cautious. But it did not indicate the reflexive hostility that might be expected, given the polarised nature of the debate.

There are immediate political implications of my proposal at both the state and federal level. It will be more difficult for the Coalition-dominated committees running the two inquiries to bring down a report favourable to nuclear power without addressing the necessary conditions – including a carbon price. If the government’s hostility to carbon pricing is such that a serious proposal for nuclear power cannot be considered, it will at least be clear that this option can be abandoned for good.

In the admittedly unlikely event that the Coalition government shows itself open to new thinking, the focus turns to Labor and the Greens.

Given the urgency of addressing climate change – a task that is best addressed through a carbon price – it makes no sense to reject action now on the basis that it opens up the possibility of nuclear power sometime in the 2030s. And, if renewables and storage perform as well as most environmentalists expect, nuclear power will be unable to compete even then.

Political hardheads will doubtless say that this is all impossible, and they may be right. But in a world where Donald Trump can win a US presidential election, and major investment banks support UK Labour leader Jeremy Corbyn over Prime Minister Boris Johnson, “impossible” is a big claim

In the absence of any prospect of progress on either energy or climate, the grand bargain I’ve proposed is at least worth a try.The Conversation

Designing Climate Solutions: A Policy Guide for Low-Carbon Energy

1610919564With the effects of climate change already upon us, the need to cut global greenhouse gas emissions is nothing less than urgent. It’s a daunting challenge, but the technologies and strategies to meet it exist today. A small set of energy policies, designed and implemented well, can put us on the path to a low carbon future. Energy systems are large and complex, so energy policy must be focused and cost-effective. One-size-fits-all approaches simply won’t get the job done. Policymakers need a clear, comprehensive resource that outlines the energy policies that will have the biggest impact on our climate future, and describes how to design these policies well.

This Changes Everything: Capitalism vs. The Climate

by Naomi Klein
1451697392In This Changes Everything Naomi Klein argues that climate change isn’t just another issue to be neatly filed between taxes and health care. It’s an alarm that calls us to fix an economic system that is already failing us in many ways. Klein meticulously builds the case for how massively reducing our greenhouse emissions is our best chance to simultaneously reduce gaping inequalities, re-imagine our broken democracies, and rebuild our gutted local economies. She exposes the ideological desperation of the climate-change deniers, the messianic delusions of the would-be geoengineers, and the tragic defeatism of too many mainstream green initiatives. And she demonstrates precisely why the market has not—and cannot—fix the climate crisis but will instead make things worse, with ever more extreme and ecologically damaging extraction methods, accompanied by rampant disaster capitalism.
