Is nuclear energy regaining vitality? | EUROtoday

A decade in the past, it appeared as if the worldwide nuclear trade was in an irreversible decline.

Concerns over security, price, and what to do with radioactive waste had sapped enthusiasm for a expertise as soon as seen as a revolutionary supply of considerable low-cost vitality.

Yet now there’s widespread speak of a revival, fuelled by tech giants Microsoft, Google and Amazon all saying investments within the sector, in addition to the rising pressures on rich nations to curb their carbon emissions.

But how actual is the comeback?

When business nuclear energy was first developed within the Nineteen Fifties and Sixties, governments have been seduced by its seemingly limitless potential.

Nuclear reactors may harness and management the identical superior forces launched by atomic bombs – to offer electrical energy for tens of millions of properties. With a single kilogram of uranium yielding some 20,000 instances as a lot vitality as a kilogram of coal, it appeared like the longer term.

But the expertise additionally impressed public concern. And that concern gave the impression to be justified by the Chernobyl catastrophe, which unfold radioactive contamination throughout Europe in early 1986.

It fuelled widespread public and political opposition – and slowed the expansion of the trade.

Another accident, on the Fukushima Daichi plant in Japan in 2011, re-energised considerations about nuclear security. Japan itself shut down all of its reactors within the speedy aftermath, and solely 12 have since restarted.

Germany determined to section out nuclear energy altogether. Other international locations scaled again plans to put money into new energy crops, or prolong the lives of ageing amenities.

According to the International Atomic Energy Agency, this led to the lack of 48GW of electrical energy era globally between 2011 and 2020.

But nuclear growth didn’t cease. In China, for instance, there have been 13 nuclear reactors in 2011. There at the moment are 55, with one other 23 below building.

For Beijing, scrambling to fulfill quickly rising electrical energy demand, nuclear had, and nonetheless has, a significant position to play.

Now curiosity within the sector appears to be rising elsewhere as soon as once more. This is partly as a result of developed international locations are looking for methods to fulfill vitality demand, whereas striving to fulfill emissions discount targets below the Paris Agreement.

With 2024 projected to be the warmest yr on document, the stress to chop carbon emissions is mounting. A renewed concentrate on vitality safety, within the wake of Russia’s invasion of Ukraine, has additionally been an element.

South Korea, for instance, just lately scrapped plans to section out its massive fleet of nuclear energy stations over the subsequent 4 many years – and can construct extra as a substitute.

And France has reversed plans to scale back its personal reliance on nuclear vitality, which supplies 70% of its electrical energy. Instead, it needs to construct as much as eight new reactors.

In addition, final week the US authorities reaffirmed on the United Nations Climate Change Conference, or Cop29, held in Azerbaijan, that it intends to triple nuclear energy era by 2050.

The White House had initially pledged to do that on the aspect traces of final yr’s convention, Cop28. A complete of 31 international locations have now agreed to attempt to triple their use of nuclear energy by 2050, together with the UK, France and Japan.

Also at Cop29, which ends on Friday, 22 November, the US and UK introduced that they would collaborate to hurry up the event of latest nuclear energy expertise.

This follows after it was agreed within the last assertion or “stocktake” of final yr’s Cop28 that nuclear ought to be one of many zero or low emission applied sciences to be “accelerated” to assist fight local weather change.

But starvation for clear energy isn’t just coming from governments. Technology giants are striving to develop an increasing number of purposes that use synthetic intelligence.

Yet AI depends on information – and information centres want fixed, dependable electrical energy. According to Barclays Researchinformation centres account for 3.5% of electrical energy consumption within the US right now, however that determine may rise to greater than 9% by the top of the last decade.

In September, Microsoft signed a 20-year deal to purchase energy from Constellation Energy, which is able to result in the reopening of the notorious Three Mile Island energy station in Pennsylvania – the positioning of the worst nuclear accident in US historical past, the place a reactor suffered a partial meltdown in 1979.

Despite its tainted public picture, one other reactor on the plant continued to generate electrical energy till 2019. Constellation’s chief government Joe Dominguez described the deal to reopen it as a “powerful symbol of the rebirth of nuclear power as a clean and reliable energy resource”.

Other tech giants have taken a distinct method. Google plans to purchase vitality produced from a handful of so-called Small Modular Reactors or SMRs – a nascent expertise supposed to make nuclear vitality simpler and cheaper to deploy. Amazon can be supporting SMR growth and building.

SMRs themselves are being promoted, partially, as an answer to one of many greatest drawbacks dealing with nuclear energy right now. In western nations, new energy stations need to be constructed to exacting fashionable security requirements. This makes them prohibitively costly and complex to construct.

Hinkley Point C is an efficient instance. Britain’s first new nuclear energy station for the reason that mid-Nineteen Nineties is being constructed on a stretch of distant shoreline in southwest England.

It is supposed to be the primary of a batch of latest crops to interchange the nation’s ageing reactor fleet. But the mission is operating some 5 years delayed and can price as much as £9bn ($11.5bn) greater than deliberate.

It will not be an remoted case. The US’s latest reactors at Plant Vogtle in Georgia opened seven years late, and value greater than $35bn – effectively over double their authentic funds.

SMRs are designed to resolve this downside. They might be smaller than conventional reactors, utilizing standardised components that may be assembled shortly, at websites near the place the ability is required.

But whereas there are some 80 totally different designs below growth globally, in keeping with the International Atomic Energy Agency, the idea has but to be confirmed commercially.

Opinions about nuclear energy stay extremely polarised. Supporters declare the expertise is indispensable if local weather targets are to be reached. Among them is Rod Adams, whose Nucleation Capital fund promotes funding in nuclear expertise.

“Nuclear fission has a seven-decade history showing it is one of the safest power sources available,” he explains.

“It is a durable, reliable source of power with low ongoing costs already, but capital costs have been too high in Western countries.”

Opponents though, insist nuclear power is not the answer.

According to Professor M.V. Ramana of the University of British Columbia, it is “a folly to consider nuclear energy as clean”. It is, he says, “one of the most expensive ways to generate electricity. Investing in cheaper low-carbon sources of energy will provide more emissions reductions per dollar.”

If present tendencies do herald a brand new nuclear age, one outdated downside stays. After 70 years of atomic energy, there’s nonetheless disagreement over what to do with the accrued radioactive waste – a few of which is able to stay hazardous for a whole bunch of 1000’s of years.

The reply being pursued by many governments is geological disposal – burying the waste in sealed tunnels deep underground. But just one nation, Finland, has truly constructed such a facilitywhereas environmentalists and anti-nuclear campaigners argue that dumping waste out of sight and out of thoughts is just too dangerous.

Solving that conundrum could also be a key think about dictating whether or not there actually might be a brand new age of nuclear energy.
