Google to buy nuclear power for AI datacentres in ‘world first’ deal

A picture


Google has signed a “world first” deal to buy energy from a fleet of mini nuclear reactors to generate the power needed for the rise in use of artificial intelligence.The US tech corporation has ordered six or seven small nuclear reactors (SMRs) from California’s Kairos Power, with the first due to be completed by 2030 and the remainder by 2035.Google hopes the deal will provide a low-carbon solution to power datacentres, which require huge volumes of electricity.The company, owned by Alphabet, said nuclear provided “a clean, round-the-clock power source that can help us reliably meet electricity demands”.The explosive growth of generative AI, as well as cloud storage, has increased tech companies’ electricity demands.

Last month, Microsoft struck a deal to take energy from Three Mile Island, activating the nuclear plant for the first time in five years.The site, in Pennsylvania, was the location of the most serious reactor meltdown in US history, in March 1979.Amazon bought a datacentre powered by nuclear energy in March, also in Pennsylvania, from Talen Energy.The locations of the new Google plants and financial details of the agreement were not revealed.The tech company has agreed to buy a total of 500 megawatts of power from Kairos, which was founded in 2016 and is building a demonstration reactor in Tennessee, due to be completed in 2027.

Michael Terrell, the senior director for energy and climate at Google, said: “The grid needs new electricity sources to support AI technologies that are powering major scientific advances, improving services for businesses and customers, and driving national competitiveness and economic growth,“This agreement helps accelerate a new technology to meet energy needs cleanly and reliably, and unlock the full potential of AI for everyone,”Mike Laufer, the chief executive and co-founder of Kairos, said: “We’re confident that this novel approach is going to improve the prospects of our projects being delivered on cost and on schedule,”The deal, which is subject to regulatory permits, represents a vote of confidence in SMR technology,The smaller, factory-built power plants are designed to cut the cost overruns and delays often experienced in building bigger plants.

However, critics argue that SMRs will be expensive because they may not be able to achieve the same economy of scale as larger plants,SMRs are defined as reactors with a maximum output of 300 megawatts (MW) that can produce more than 7m kilowatt hours a day,However, some designs are larger than this and the term is often simply used to describe factory-built, modular plants,Sign up to Business TodayGet set for the working day – we'll point you to all the business news and analysis you need every morningafter newsletter promotionLarge nuclear power plants typically have an output of more than a gigawatt and the planned plant at Hinkley Point C in Somerset is expected to produce 3,2GW, enough electricity to power 6m homes.

In the UK, companies are bidding to be selected by the government to develop their SMR technologies as ministers aim to revive the country’s nuclear industry.One of the bidders, Rolls-Royce SMR, received a significant boost last month when it was selected by the Czech government to build a fleet of reactors.Rolls has said one of its SMRs would be a tenth of the size of a large power plant and produce enough power for a million homes.It has been argued that SMRs can complement output from large-scale reactors as countries attempt to move away from power generated by fossil fuels.Proponents argue that they provide a more flexible approach to constructing new nuclear plants, as they require less cooling water and a smaller footprint, opening up a greater variety of potential site locations.

However, environmental campaigners and academics have argued against the technology, claiming they have no proven UK track record and that resources would be better spent on renewables such as more offshore wind,

Falafel, dips and mansaf: the Palestinian chef serving dishes ‘made with love’ in Melbourne

It’s an overcast afternoon in September and a crowd is gathering in the Melbourne suburb of Brunswick. The draw card: an unassuming food trailer parked in a loading bay on Hope Street, just off the suburb’s main drag.Brunswick is already famed for its vibrant Middle Eastern eateries and Aheda Amro, the woman behind this latest addition to the scene, knew it would be the perfect location to launch the project she has been working towards for the past five years.Originally from Halhul, a small city in Palestine’s West Bank, since arriving as an asylum seeker in 2018 Amro has been on a mission to bring the flavours of her homeland to Melbourne.The launch of her food van Aheda’s Kitchen is the result of years of determination and hard work; and not just Amro’s but that of the vast network of volunteers she has galvanised to help make her dream a reality

What are the best fillings for a jacket potato? | Kitchen aide

There’s no denying a jacket potato is one of life’s simple pleasures, but sometimes minimalism is not the order of the day. So if, say, tuna mayo is as edgy as your fillings get, it’s time to broaden your horizons: “For a rich, savoury twist, crisp chorizo and cream cheese make the ultimate indulgent filling,” says Poppy O’Toole, spud queen and author of The Actually Delicious Slow Cooker. She starts by frying chopped chorizo in a dry pan until it releases its oil, then stirs half the meat and its fat through some cream cheese. “Butter up your jacket potato, top with a big spoonful of the chorizo cream cheese, and sprinkle the rest of the fried chorizo on top for a satisfying, flavour-packed meal.”The Guardian’s journalism is independent

Georgina Hayden’s recipe for sausage meatballs with beans and caramelised peppers

For such a short ingredients list, this recipe is packed with flavour and something I cook almost weekly for my family (with slight variations). Using sausagemeat instead of mincemeat means instant flavour, and you can use whatever sausages you like (I love the ones with lots of fennel). You could serve this as is, on toast (think nostalgic beans on toast with sausages), or even substitute the beans for mini pasta shells – it’s a malleable and forgiving dish.If you have the time, give the peppers a little longer to cook, to make them extra sweet.Prep 10 min Cook 35 min Serves 42 tbsp olive oil6 sausages (about 400g)4 garlic cloves, peeled and finely chopped½ tsp sweet smoked paprika 3 peppers (red, orange or yellow), halved, seeds and pith removed, flesh very finely slicedSea salt and black pepper800g (2 x 400g tins) cannellini beans, drained ½ bunch flat-leaf parsley, finely choppedPut the oil in a large frying pan on a medium-low heat

Mulled white wine? Perfect for Christmas guzzling

For the same reason you wouldn’t enjoy a protein shake at your anniversary dinner, you wouldn’t enjoy mulled wine at any time other than Christmas. Mulled wine is a drink that is tied to a specific moment. It’s not enough for the weather to be cold, grey and rainy (god knows we experience that often enough in the UK), it needs to feel festive – preferably in the presence of at least one adult dressed as an elf.In my head, mulled wine is a sort of goth sangria, a concoction that is flavoured, sweetened and spiced into something else entirely. This is also why people who don’t think of themselves as wine drinkers tend to enjoy mulled wine and sangria

Rachel Roddy’s recipe for pumpkin, lentil and barley soup | A kitchen in Rome

Barley and, in no particular order, emmer and einkorn, wheat, rice, sorghum, peanuts, squash, cassava, lentils, chickpeas, bitter vetch and flax are the so-called founder crops that formed the basis of early agricultural economies in the various centres of domestication all over the planet. My first thought when I read this list of ingredients was: “What a fantastic soup!” And my second was: “What is bitter vetch?” The answer is it’s an ancient legume in the expansive Vicia genus that’s related to broad beans, although physically closer to the lentil and, taste-wise, nearer to a pea, only bitter. So, if you do make the founder crop soup, remember to parboil the bitter vetch several times, changing the water in between, before adding it to the soup. A small, portable oil press is also helpful, if you want to go all the way and turn flax seeds into oil, but remember to warm it gently.The Guardian’s journalism is independent
