Nuclear Power Only Way to Meet Net-Zero Carbon Dioxide Emissions Targets

The climate alarmists and RE rent-seekers pushing net-zero carbon dioxide emissions targets hate nuclear power because it’s the only way of satisfying any such target.

And at the heart of that proposition, is the fact that the true cost of wind and solar are truly out of this world.

As a partial concession to their hopeless intermittency, wind and solar proponents talk about the need to add a little “firming” capacity to the grid for when the sun sets and/or calm weather sets in.

To the uninitiated, seeking out “firming” capacity might sound like chasing cheap Viagra from a Chinese website.

In the realm of the so-called “inevitable” transition to an all wind and sun powered future, “firming” capacity may not be fake, but it certainly ain’t cheap.

Thanks to its self-inflicted and suicidal renewable energy policies, the future of Australia’s power pricing and supply situation is diabolical.

The expansion and extension of mandated subsidies to wind and solar has the operators of coal-fired power plants on the ropes, as it was designed to do.

Plans to shut down another couple of very large coal-fired plants have energy wonks fretting about the next high-demand day, that coincides with sunset during calm weather. A point when the grid will face an inevitable total collapse; load shedding (aka demand management, aka Cuban style power rationing) is a routine feature of those occasions, even now.

The threat posed, has drawn focus on the cost of continuing down the path of chaotically intermittent wind and solar backed up with either mythical mega-batteries or pumped hydro. The costs of which, as appears below, are astronomical.

What the numbers reveal, however, is that switching to nuclear power is the most cost-effective method of delivering electricity and doing so without generating any carbon dioxide gas in the process.

For those concerned about the latter part of the equation, nuclear is the only method of ever meeting net-zero targets (whatever their merits may be).

The real cost of firming intermittent power in the grid

The real cost of backing up the intermittent provision of wind and solar power has been spelled out in a comprehensive model that has achieved virtually no coverage in the public discussion of energy issues. This is a scandalous situation that reflects the ignorance and virtually criminal negligence of the journalists and commentators of the nation. This is a short version of the report.

According to all the people who are supposed to know about these things the road to net zero is clear and the days of the coal power are numbered because wind and solar power are so much cheaper. How much cheaper? Well the inputs of wind and sunbeams come free of charge, so how much cheaper can you get!

The CSIRO GenCost study is regarded as the last word on the matter and who can challenge the authority of the CSIRO? It is disappointing to find that the study is full of holes and dubious assumptions. The biggest hole of all is the failure to account for the full cost of firming the intermittent inputs. This is currently provided by the much maligned coalers and it comes free of charge to the wind and solar industries. See here for the frog and centipede relationship between conventional power and the predatory parasites of the RE industry.

In November 2020 a group of consultants tabled a report in the NSW Parliament with the results of some elaborate modelling work to generate the total System Levelised Cost of Energy (SLCOE) which is defined as — “…the average cost of producing electric energy from the combination of generation technologies chosen for the system over its entire lifetime”

The models include additional transmission costs for various options including replacing brown coal with nuclear energy, replacing coal with gas and 100% RE with hydro and storage.

Summary of Results

The best policy option to control costs and minimise emissions would appear to be to replace coal generation with nuclear power.

Case 1. This is the current situation, with over 70% of power generated by coal the estimated cost is $68.87/MWh.

Case 2 shows the effect of introducing 3,000 MW of nuclear power capacity into the Case 1 mix to replace brown coal. This raises the cost to $72.48/MWh while reducing emissions by around 23%.

Case 3 shows the effect of replacing all coal in Case 1 with nuclear power. Emissions fall by some 93%, with the cost increasing to $90.23/MWh.

Case 4 shows the effect of the combination of generation technologies projected by the Australian Energy Market Operator (AEMO) to 2040, as shown in its Integrated System Plan (ISP) of July 2018. The cost is in the order of $250/MWh.

Case 5 shows the effect of replacing all coal in Case 1 with CCGT. This shows an increase in cost to approach $100/MWh.

Case 6 shows a 100% renewable mix comprising solar PV, wind and hydro with support from pumped storage and some battery storage. Because of low capacity factors, solar PV and wind require a combined total of 110,000 MW of capacity. There is also a need for 30,000 MW of pumped storage capacity for 3 days. To this must be added high-cost additional transmission to get the power to points of high consumption where it is needed, making a total SLCOE of $415.50 I MWh.

Supplementary Information and Comments from the Authors

1. Wind-up subsidies for intermittent power generation
2. Add a capacity market component to the National Electricity Market
The current NEM is an energy-only market, which does not give clear signals when more or replacement dispatchable generation investment is needed. This weakness has been a key factor in the current absence of new dispatchable investment, i.e. power which can be delivered at the time it is needed by customers.

3. Remove the ban on nuclear power
This ban is the result of a political deal done 20 years ago. It has no scientific merit and is now an obstacle to much-needed decisions for the longer-term future. It prohibits by law the development of emissions-free, reliable, affordable nuclear power for Australia. The removal of the ban would allow more competition between various technologies to supply our future electricity needs.

  1. Peter Pronczak says:

    It is hypocritical to have been operating a nuclear plant for all these years in Sydney, NSW regardless it makes medical isotopes, it is still a nuclear facility.
    Now all parties have agreed to nuclear powered submarines where does it leave them on the hypocrisy scale?
    A few years ago we received a nuclear waste shipment from France that was mainly contaminated dirt. Where did it go? The public don’t know.

    Thanks STT your post 2021/08/16 “200 small nuclear reactors are presently powering 160 ships and submarines all around the world”. It came at the right time as Prof Ian Lowe was flogging his book – outdated nuclear thinking; including ‘fusion energy only managed millisecond run’.
    Don’t know if a reference to Planet of the Humans was passed on to him. Now who could have wanted to ban that film?

    For anyone who missed it the 2022/05/01 post had a link the major parties appear to have put a D Notice on popular mass media reporting it.

    Now marine Prof Andrew ‘Twiggy’ Forrest is going to lumber us with a hydrogen facility at the Port of Gladstone, QLD. Apart from snap frozen fish it gives a bit of a sinking feeling.

  2. Three days’ storage isn’t nearly enough, at least not for Britain, Texas, or California, and probably not for Australia. Several people have used real data, not vague hand waving, to compute that 15-125 days’ storage are needed, depending upon location, demand, and the mix of wind and solar. Activists say the an all-electric USA energy economy would have 1,700 GWe average demand. Use the minimum storage estimate (something a real engineer would never do). Look in Tesla’s catalogue for prices and longevity of the PowerWall2. Do the really simple fourth-grade arithmetic (not higher mathematics). The result is AT LEAST FOUR TIMES TOTAL USA GDP EVERY YEAR for batteries alone.

  3. Bob Daye says:

    The push for “Net-Zero Emission” is criminal behavior based upon an unproven theory that human activity is causing harmful global climate change.
    Their goals are sinister and are designed to reduce our standard of living and freedom. One of the most effective ways of removing personal liberty is to limit mobility. EV’s will do just that.

  4. There is no need to meet net zero targets. All models based on this are built on quicksand, carbon does nothing to the climate, oxygen, heat and cool does and it’s in balance and always will be out of our control. Water vapor is found in atmosphere in quantities around 10,000% more than co2. To argue to build nuclear to fix the problem that does not exist is a bad approach as it tends to reinforce the climate change lies, thus, they will eventually take credit for “fixing the problem” with nuclear. Since the belief in co2 effects will remain, as will many petroleum based cars, trucks, etc. all those will be heavily taxed and controlled. They will even force you to wear a co2 monitor permanently installed in the back of your nose and throat as an improvement to those covid sticks that merely test you to see if you are alive. These will feed data to the One Crappy World Government (OCWG) computers run by Shill Gates Farms (SGF) that is sole owner of all productive soil renamed Soilent Green Farms (SGF) so that if you exhale more than your quota you will be billed and no one will mention the elephant in the China shoppe that all the products and systems that manage all these methodologies to zero carbon emissions rely on petroleum 100% which is never mentioned by any of these marketing shills that claim the goal is to leave all fossil fuels in the ground by 2050 and none of these manipulative monsters care one bit about your health or the planet as everything they do is based on oil and everything they manufacture relies on it especially those pipelines to your money.

    • Find us a way of getting a western government elected that rejects the man made carbon dioxide gas is ruining the planet mantra, and we’ll take your point. Every political party with any hope of governing sticks with it, the MSM ensures it, the few minor parties with the wit and temerity to challenge it, get pilloried because the narrative is so entrenched.

      So, for the next generation, we’re stuck with it. Australia is closing coal-fired plants, driven out of business by subsidised wind and solar. If we don’t go nuclear, our entire power grid will collapse. Of course, we could embrace coal. But no major party is game, for the reasons above.

      And in your part of the world, the USA, don’t ignore your nuclear power generation capacity and the benefits it brings. If you want to retain it, your best hope is to use the mantra against the wind and solar cult, to prevent them from dismantling it.

      • C. Paul Barreira says:

        Perhaps the more pertinent argument might be for immediate action regarding nuclear power generation, particularly given the decade at least before any electricity could be produced. Media won’t be interested, it is true, but various individuals within the major political parties might begin to argue the point. But it will be painfully slow with much distress brought about by the unreliables and their backers; it may also need to be federally directed.

      • Graeme No.3 says:

        @ C. Paul Barreira:
        Yes, by the time a convinced Federal Govt. could drive a nuclear plant through is at least 10 years. Firstly we have to decide what type, molten salt, small mini-reactors or whatever. It would help if we had people backing some such, but I think that getting to a Federal decision and a supply of experienced engineers would take 10 years.
        AS for renewables I would take them at their ‘word’ that “renewables are the cheapest means of generation” and dump all subsidies.
