WASHINGTON (Reuters) -Alphabet's Google said on Monday it has struck a deal to buy power from a project in Virginia fueled by fusion, the reaction that powers the sun and the stars but is not yet commercial on Earth.
Google signed what it called the technology's first direct corporate power purchase agreement with Commonwealth Fusion Systems, a company that spun off from the Massachusetts Institute of Technology in 2018.
The deal is for 200 megawatts of power, about enough to power a small city, from CFS's ARC project that is being developed in Virginia, home to the world's biggest hub of energy-hungry data centers. Financial details of the deal were not disclosed.
Physicists at national laboratories and companies have been trying for decades to use lasers or, in the case of CFS, large magnets to foster fusion reactions, in which light atoms are forced together to release large amounts of energy.
In 2022, the Lawrence Livermore National Laboratory in California briefly achieved net energy gain in a fusion experiment using lasers.
But achieving so-called "engineering break-even," in which more energy comes out of a reaction than the overall energy that goes into a fusion plant to get a reaction going, has been elusive. And for a plant to generate power from fusion, the reactions must be constant, not rare.
"Yes, there are some serious physics and engineering challenges that we still have to work through to make it commercially viable and scalable," Michael Terrell, Google's head of advanced energy, told reporters in a call. "But that's something that we want to be investing in now to realize that future."
As artificial intelligence and data centers boost power demand around the world, interest in fusion is spiking. Fusion, unlike nuclear fission, in which atoms are split, does not generate large amounts of radioactive waste. In addition, fusion, if successful, could help fight climate change.
CFS aims to generate power from the 400 MW project known as ARC in the early 2030s but must first clear the scientific hurdles.
"Without partnership and without being bold and setting a goal and going for it, you won't ever reach over those challenges," Bob Mumgaard, CFS's CEO and co-founder, told reporters. He said the ARC plant will teach CFS about the "teething phase" of fusion, in which he expects to learn about how often fusion machines break down and how they can run reliably.
Google also said on Monday it was increasing its investment in CFS, but did not disclose the amount. Google was one of many investors that invested a total of $1.8 billion into CFS in 2021. Mumgaard said Google's investment on Monday was "comparable" to its 2021 one.

REUTERS/Dado Ruvic/Illustration/File Photo (Reuters) -Elon Musk's xAI has completed a $5 billion debt raise alongside a separate $5 billion strategic equity investment, Morgan Stanley said on Monday, as the startup looks to expand its AI infrastructure through data centres amid intensifying competition in the industry. The $5 billion raised in debt consists of financing of secured notes and term loans, Morgan Stanley in a statement posted on social media platform X. The deal was oversubscribed and included prominent global debt investors, it added. Reuters earlier reported that xAI was on track to close on a $5 billion debt raise led by Morgan Stanley, despite tepid investor demand. In a separate report, Bloomberg News said that xAI was in talks to raise $4.3 billion through an equity investment on top of its $5 billion debt funding plans. XAI did not immediately respond to a Reuters request for comment outside regular business hours. The proceeds will support xAI's continued development of AI solutions, a data center and its flagship Grok platform, the bank said. Apart from selling debt, xAI has also been in talks to raise about $20 billion in equity, which would value the company at more than $120 billion, with some investors placing valuations as high as $200 billion.

Landmark EU tech rules holding back innovation, Google says

REUTERS/Carlos Barria/File Photo BRUSSELS (Reuters) -Alphabet's Google will on Tuesday warn EU antitrust regulators and its critics that landmark European Union rules aimed at reining in Big Tech are hampering innovation to the detriment of European users and businesses. The U.S. tech giant will also urge regulators to give more detailed guidance to help it comply with the rules, and ask its critics to provide evidence of costs and benefits to prove their case. Google is under pressure to address charges under the EU's Digital Markets Act that it favours its own services such as Google Shopping, Google Hotels and Google Flights over rivals. The charges may result in fines of as much as 10% of its global annual revenue. Earlier this month, Google proposed more changes to its search results to better showcase rival products, but critics say these still do not ensure a level playing field. "We remain genuinely concerned about real world consequences of the DMA, which are leading to worse online products and experiences for Europeans," Google's lawyer Clare Kelly will tell a workshop organised by the European Commission to give Google critics the opportunity to seek clarifications. She will say changes implemented by Google to date after discussions with the Commission and its critics have resulted in European users paying more for travel tickets as they cannot directly access airline sites, according to a copy of her speech seen by Reuters. Kelly will also say European airlines, hotels and restaurants have reported up to a 30% loss in direct booking traffic, while users have complained about clunky workarounds. Google's other lawyer, Oliver Bethell, will ask regulators to spell out in detail what the company needs to do, and critics to come up with hard evidence. "If we can understand precisely what compliance looks like, not just in theory, but taking account of on the ground experience, we can launch compliant services quickly and confidently across the EEA," he will say. The EEA is the 27 EU countries, Iceland, Liechtenstein and Norway. "We need help identifying the areas where we should focus. That means bringing real evidence of costs and benefits that we can take account of with the Commission," Bethell said. The day-long workshop starts at 0700 GMT.

China's factory activity returns to growth in June, Caixin PMI shows

Photographer: Qilai Shen/Bloomberg BEIJING: China's factory activity returned to expansion in June, supported by an increase in new orders that lifted production, a private-sector survey showed on Tuesday. The Caixin/S&P Global manufacturing PMI rose to 50.4 in June from 48.3 in May, surpassing analysts' expectations in a Reuters poll. The 50-mark separates growth from contraction. The reading contrasts with China's official PMI on Monday that showed factory activity shrank for a third straight month. But new export orders in both surveys remained in negative terrain in June, suggesting potential challenges for exports in the second half of the year. "Overall, manufacturing supply and demand recovered in June," said Wang Zhe, economist at Caixin Insight Group. "However, we must recognise that the external environment remains severe and complex, with increasing uncertainties. The issue of insufficient effective demand at home has yet to be fundamentally resolved." Overall new orders increased in June after falling in May, with factory bosses citing an improvement in trade conditions and promotional activities to boost sales, the Caixin survey showed. That drove factory output to the highest reading since November 2024. Due to higher new work inflows and a reduction in workforce capacity, accumulation of backlogged orders was recorded for the first time in three months. Employment across the Chinese manufacturing sector contracted in June amid both resignations and redundancies, according to respondents. Some smaller exporters had to sell at a loss or to cut wages and jobs to stay afloat. Average output charges fell at the most pronounced pace since January, which in turn was supported by lower input costs. Export charges continued to increase, however, driven by rising shipping and logistics costs. The level of business confidence eased from May and remained below the series long-run trend. Goldman Sachs economists said the upcoming July Politburo meeting, a key meeting to discuss the economy, is unlikely to result in major stimulus measures, as policymakers appear satisfied with the economic performance so far this year. In trade developments, U.S. Treasury Secretary Scott Bessent announced last week that the United States and China had resolved issues surrounding shipments of Chinese rare earth minerals and magnets, building on a deal reached in May in Geneva. China's Commerce Ministry said on Friday export applications for controlled items would be approved in accordance with the law. - Reuters
