Dream of unlimited, clean nuclear fusion energy within reach

by Gareth Willmer
The old joke is that nuclear fusion is always 30 years away. Yet the dream of abundant clean energy is no laughing matter as we meet an ITER researcher to catch up on progress at the reactor facility.
The Sun has fuelled life on Earth for billions of years, creating light and heat through nuclear fusion. Given that incredible power and longevity, it seems there can hardly be a better way to generate energy than by harnessing the same nuclear processes that occur in our own and other stars.
Nuclear fusion reactors aim to replicate this process by fusing hydrogen atoms to create helium, releasing energy in the form of heat. Sustaining this at scale has the potential to produce a safe, clean, almost inexhaustible power source.
The quest began decades ago, but could a long-running joke that nuclear fusion is always 30 years away soon start to look old?
Some hope so, following a major breakthrough during a nuclear-fusion experiment in late 2021. This came at the Joint European Torus (JET) research facility in Oxfordshire, UK, in a giant, doughnut-shaped machine called a tokamak.
Inside, superheated gases called plasmas are generated in which the fusion reactions take place, containing charged particles that are held in place by powerful magnetic fields. Such plasmas can reach temperatures of 150 million degrees Celsius, an unfathomable 10 times hotter than the Sun’s core.
In a sustained five-second burst, researchers in the EUROfusion consortium released a record-breaking 59 megajoules (MJ) of fusion energy. This was almost triple the previous 21.7 MJ record set at the same facility in 1997, with the results touted as ‘the clearest demonstration in a quarter of a century of the potential for fusion energy to deliver safe and sustainable low-carbon energy’.

The results provided a major boost ahead of the next phase of nuclear fusion’s development. A larger and more advanced version of JET known as ITER (meaning “The Way” in Latin) is under construction on a 180-hectare site in Saint-Paul-lès-Durance, southern France.
ITER, which is being built as a collaboration between 35 nations, including those in the EU, is aimed at further firming up the concept of fusion. One of the most complicated machines ever to be created, it was scheduled to start generating its first plasma in 2025 before entering into high-power operation around 2035 – although researchers on the project expect some delays because of the pandemic.
Major milestone
The results at JET represent a major landmark, said Professor Tony Donné, programme manager of the EUROfusion project, a major consortium of 4 800 experts, students and facilities across Europe. ‘It’s a huge milestone – the biggest for a long time,’ he said.
‘It’s confirmed all the modelling, so it has really increased confidence that ITER will work and do what it’s meant to do.’ While the energy generated at JET lasted just a few seconds, the aim is to ramp this up to a sustained reaction that produces energy.
The results were the culmination of years of preparation, with Prof Donné explaining that one of the key developments since 1997 involved changing the inner wall of the JET vessel.
Previously, the wall was made of carbon, but this proved too reactive with the fuel mix of deuterium and tritium, two heavier isotopes – or variants – of hydrogen used in the fusion reaction. This resulted in the formation of hydrocarbons, locking up the tritium fuel in the wall.
In the rebuild, which involved 16 000 components and 4 000 tonnes of metal, the carbon was replaced with beryllium and tungsten to reduce tritium retention. Ultimately, the team was able to cut the amount of trapped fuel by a large multiple, contributing to the success of the recent fusion shot.
DEMO run
In preparation for the next stage of fusion’s epic journey, upgrades to JET ensured that its configuration aligns with the plans for ITER. Further in the future, the next step beyond ITER will be a demonstration power plant known as DEMO, designed to send electricity into the grid – leading on to fusion plants becoming a commercial and industrial reality.
‘ITER is a device which will create 10 times more fusion energy than the energy used to heat the plasma,’ said Prof Donné. ‘But as it is an experimental facility, it will not deliver electricity to the grid. For that, we need another device, which we call DEMO. This will really bring us to the foundations for the first generation of fusion power plants.’
Prof Donné added: ‘JET has shown now that fusion is plausible. ITER has to show that it’s further feasible, and DEMO will need to demonstrate that it really works.’
Planned to provide up to 500 megawatts (MW) to the grid, he thinks it is realistic for DEMO to come into operation around 2050. ‘We hope to build DEMO much faster than we built ITER, making (use of the) lessons learned,’ he said.
Yet there are other key challenges to overcome on the way to getting nuclear fusion up and running. Not least is that while deuterium is abundant in seawater, tritium is extremely scarce and difficult to produce.
The researchers therefore plan to develop a way of generating it inside the tokamak, using a ‘breeding blanket’ containing lithium. The idea is that high-energy neutrons from the fusion reactions will interact with the lithium to create tritium.
Essential energy
Prof Donné said nuclear fusion could prove a pivotal green and sustainable energy source for the future. ‘I would say it’s essential,’ he said. ‘I’m not convinced that by 2050 we can make the carbon dioxide transition with only renewables, and we need other things.’
And although he says the current method of creating nuclear energy through fission is becoming safer and safer, fusion has key advantages. Proponents for ITER talk of benefits such as an absence of meltdown risk, adding that nuclear fusion does not produce long-lived radioactive waste and that reactor materials can be recycled or reused within 100 to 300 years.
‘It’s definitely much safer,’ said Prof Donné. Referencing the stigma carried by nuclear energy, he said, ‘What we see when we interact with the public is that people very often haven’t heard about nuclear fusion. But when we explain the pros and cons, then I think people get positive.’
Referring to Lev Artsimovich, dubbed the “father of the tokamak”, he said, ‘Artsimovich always said fusion will be there when society really needs it. If we get fusion up and running, then really we have a very safe and clean energy source which can give us energy for thousands of years.’

EU countries are purchasing more LNG from Russia

Europe again risks becoming dependent on Russian LNG. EU countries are purchasing more gas from Russia than before the Ukrainian conflict. From January to July, they purchased 40% more raw materials from it compared to the same period in 2021, Chinese publication Sina writes.
On August 30, the non-governmental organization Global Witness said that in the first seven months of 2023, European Union countries spent almost 5.3 billion euros purchasing liquefied natural gas (LNG) from Russia, accounting for more than half of total imports. At the same time, Spain and Belgium have become the second and third largest buyers of Russian LNG in the world. Global Witness also found that EU members are now purchasing far more liquefied natural gas from Russia than before the Ukrainian conflict erupted in 2022.
Eurostat data also shows that in the first quarter of 2023, Russia became the second largest supplier of LNG to the eurozone, behind only the United States and ahead of such exporters of this type of gas as Qatar, Algeria, Norway and Nigeria.
According to Global Witness statistics, from January to July 2023, EU countries purchased 22 million cubic meters of Russian LNG, an increase of 40% compared to 15 million cubic meters in the same period in 2021.
Using Russian LNG prices estimated by the Center for Energy and Clean Air Research based on spot and monthly trade figures, Global Witness forecasts EU purchases in 2023 of €5.29 billion.
The growth in imports of liquefied natural gas from Russia to the EU significantly exceeds the growth in the volume of trade in Russian LNG on the world market (6%). From January to July 2023, the share of purchases from Russia in the total LNG imports of the European Union amounted to 52%. For comparison, in 2022 the share was 49%, and in 2021 – 39%.
In March 2022, the European Union proposed a plan called REPowerEU, which aims to gradually eliminate dependence on Russian natural gas by 2027. But judging by the current situation, the EU still has a long way to go to achieve this goal, as it still relies heavily on Moscow for fossil energy.
In March 2023, European Commission Energy Commissioner Kadri Simson called on EU member states and companies to stop buying Russian LNG. Spanish Energy Minister Teresa Ribera also asked local entrepreneurs not to sign new contracts for gas imports from Russia.
Currently, Spain is the second largest buyer of Russian LNG in the world, and Belgium is the third. In the first seven months of 2023, Madrid purchased about 18% of all Russian gas exports, and Brussels about 17%. These two countries are second only to mainland China at 20%. At the same time, for the same period in 2021, Spain ranked only fifth, and Belgium seventh.
Spanish utility company Naturgy has signed a major contract with France’s Total for the supply of Russian liquefied natural gas.
According to the data, natural gas reserves in Europe are currently close to 90% of capacity, but the storage limit of 100 billion cubic meters is still too low, given annual consumption of 350-500 billion cubic meters.

Guterres leads call to make Africa ‘renewable energy superpower’

The flame of injustice is “scorching hopes and possibilities” across Africa as the world grapples with the climate crisis, with the continent suffering some of the worst impacts of global warming said the UN chief on Tuesday.
Secretary-General António Guterres was addressing the African Climate Summit in Nairobi, Kenya, noting that despite “extreme heat, ferocious floods, and tens of thousands dead from devastating droughts”, the continent was responsible for less than four per cent of emissions.
“The blow inflicted on development is all around with growing hunger and displacement”, he said.
‘Quantum leap’
But amid the “climate chaos” he said it was still possible to avoid the worst, “but only with a quantum leap in climate action.”
He said far greater climate ambition was needed from all countries led by the largest emitters, in line with his Climate Solidarity Pact and Acceleration Agenda.
He called on the G20 advanced economies meeting in Delhi this week, to take responsibility and commit to reaching net zero emissions as close as possible to 2040.
Secondly, he called for “climate justice” to reach goals on renewable and affordable energy, particularly in Africa. This means operationalizing the agreed loss and damage fund, universal early warning systems, and a “course correction in the global financial system.”
‘World leader in renewable energy’
Third, Africa is rich in untapped renewable energy with the potential to become a world leader in renewables and “green growth.”
It has nearly a third of the world’s mineral reserves for solar power, electric vehicles and battery storage.
“To truly benefit all Africans, the production and trade of these critical minerals must be sustainable, transparent and just across every link of the supply chain”.
The UN chief pointed to the Greater Horn region where over 85 per cent of electricity comes from renewables. Mozambique gets nearly all its energy from green and sustainable resources.
And wind and solar projects are already helping power Egypt, Algeria, Tunisia, Morocco and South Sudan.
He called for a collective effort to create “a true” African Renewable Energy Alliance.
‘African miracle’
“Renewable energy could be the African miracle but we must make it happen. We must all work together for Africa to become a renewable energy superpower.”
Mr. Guterres told the conference of African leaders and stakeholders hosted by Kenya and the African Union Commission that he was convinced the continent “can be at the heart of a renewable future.”
He said now was the time for all nations “to stand as one in defence of our only home. Let’s deliver the climate justice that Africans, the world, and the planet we share, demand and deserve.”
Speaking at a press conference in Nairobi after his speech, the Secretary-General said it was time to end the injustices that are holding the continent back. He pledged to work closely with African leaders and organizations such as the AU, to accelerate progress.

WP: Drop in energy needs points to a further deterioration in industrial activity in Europe

Europe has an even stronger ally to keep gas prices under check heading into the colder months: extremely weak demand. The manufacturing crisis that’s plaguing the continent — industrial activity in Germany has contracted for 14 consecutive months — is the best antidote against a gas supply squeeze. With friends like that, who needs enemies? – asks ‘The Washington Post’.
Europe is defeating its energy crisis thanks to the impact that said crisis has had on its industrial heartland. Across the continent, many energy-intensive companies have either closed or reduced production after not being able to cope with higher energy prices. The fertilizer, chemical, metallurgic, glass, paper and ceramic industries are particularly affected. All those shuttered factories don’t need gas or electricity now.
In Germany, activity among energy-intensive companies plunged in June by nearly 18% versus late 2020, according to official data. During the same month, industrial gas demand also declined 18% compared with a year ago. In July, gas demand posted an even deeper plunge, falling 22.9% from a year earlier, the largest decline so far in 2023. When official industrial production data is released for July in a few weeks, that drop in energy needs points to a further deterioration in industrial activity.
Due to anemic manufacturing activity and lower-than-expected gas-burn in the electricity sector, Morgan Stanley reckons that total gas demand in Europe is running about 15% below the five-year average, even when adjusted by the impact of the weather. With consumption low and LNG supply so far plentiful, Europe has been able to inject a record amount of gas into underground storage over the spring and summer — despite most countries in the region no longer having access to Russian pipeline gas supply.
European gas stocks are nearly 92% full — a record high for this time of the year. If the current injection pace continues, inventories would reach 100% by mid-September.
And yet, it would be of little solace for the continent’s industrialists. Currently, European gas prices are running at about €35 ($38) per megawatt hour, compared with the 2010-2020 average of just over €20. Wholesale electricity prices are running above €140 per megawatt hour, more than triple the 2010-2020 average of €38.5.
The real problem is that companies know that any supply issue, real or perceived, would trigger a price rally, because even with nearly full stockpiles, Europe needs all the gas it can grab to make it through the winter. The manufacturing sector remains the go-to segment of consumption to find extra demand destruction. Hence, why so many chief executive officers are reluctant to bring back production capacity, fearing reactivating a plant only to get caught again by higher prices.
As such, the price of avoiding the energy crisis is a deep recession in the manufacturing sector, and a long-term loss of economic growth.
German businesses are increasingly curbing investments and eyeing production abroad amid high energy prices at home, informs Bloomberg.
Over half of surveyed companies say the energy transition is having negative or very negative effects on their competitiveness, according to a report by the German Chamber of Commerce and Industry. Among manufacturers, almost a third are considering or already executing a production shift abroad — twice as much as during last year’s energy crisis.
“The German economy’s confidence in energy policy has fallen to a low point,” the group’s chairman Achim Dercks said. “Concerns about competitiveness have never been greater.”
Germany’s manufacturing-heavy economy has seen a protracted period of weakness that shows few signs of abating amid plunging business confidence, and it’s the only major European nation whose output is forecast to shrink this year. While manufacturers used to enjoy relatively cheap power costs when Germany was still receiving pipeline gas from Russia, last year’s crisis forced the country to revamp its plan for future supplies. Its energy prices are currently among the highest in Europe.
While the expansion of renewable energy sources is expected to eventually bring costs down, they are likely to remain elevated until at least 2027, according to the government. Among large industrial companies — who often already have links to production abroad — one in four have already started or completed further capacity movements.
