Yet data centres built for high-performance computing and AI require much more power than a standard facility. This generates a lot more heat, which entails a further substantial increase in power demands for liquid cooling facilities<\/a>.<\/p>\n\n\n\n According to the International Energy Agency, data centres accounted for about 1 to 1.5% of global energy use in 2023<\/a>, and this figure is expected to rise significantly in the years ahead.<\/p>\n\n\n\n Additionally, cooling systems can exacerbate water shortages<\/a> in some regions, while the growing e-waste<\/a> generated from outdated equipment is also a big problem.<\/p>\n\n\n\n To try and address the energy issue, data-centre firms have been investing in renewable energy sources<\/a> like wind, solar and nuclear to reduce their carbon emissions<\/a>.<\/p>\n\n\n\n They\u2019re also using advanced cooling technologies<\/a> to make their data centres more energy efficient.<\/p>\n\n\n\n Even so, it\u2019s still going to be a major challenge to roll out enough capacity. Data centres require substantial physical space and infrastructure, making expansion both difficult and costly.<\/p>\n\n\n\n This is why US companies like Lumen Orbit<\/a> and the EU\u2019s Ascend project<\/a> are looking to space instead. Data centres beyond Earth\u2019s atmosphere would have access to continuous solar energy and could be naturally cooled by the vacuum of space.<\/p>\n\n\n\n Away from terrestrial issues like planning permission, such facilities could be rapidly deployed and expanded as the demand for more data keeps increasing.<\/p>\n\n\n\n It may sound like something from a sci-fi novel, but this concept has been gaining more attention as space technology has advanced and the need for sustainable and scalable data centres has become apparent.<\/p>\n\n\n\n Lumen, which is based in Washington, recently raised US$11 million<\/a> (\u00a38.9 million) in seed funding that will be used to build a full-scale prototype in 2025.<\/p>\n\n\n\n This facility will be geared towards taking huge amounts of raw data from other satellites, then using AI to crunch it down for transmission to Earth, taking up much less bandwidth than would otherwise be required.<\/p>\n\n\n\n Meanwhile, Ascend completed an 18-month study<\/a> last summer that found that space data centres are economically viable and environmentally feasible, provided the carbon emissions from launchers can be reduced by about tenfold.<\/p>\n\n\n\n Backed by French defence giant Thales, it aims to launch a gigawatt of capacity into space over the next 25 years.<\/p>\n\n\n\n As with all too-good-to-be-true ideas, we should certainly be in no doubt about the challenges involved in these kinds of projects.<\/p>\n\n\n\n It\u2019s still hugely expensive to launch payloads into orbit, even if companies like Elon Musk\u2019s SpaceX have been making significant steps<\/a> in reducing the cost and increasing the reliability of space launches. This may greatly limit how quickly space data centres could be launched.<\/p>\n\n\n\n There\u2019s also the fact that the latency in communication between Earth and space affects data transmission speeds.<\/p>\n\n\n\n Another Musk company, Starlink, has been making inroads into this issue with its burgeoning satellite network, which Musk claims<\/a> will be as fast as fibre broadband in the years ahead.<\/p>\n\n\n\n Maintaining space data centres poses a major challenge. Space weather, such as solar flares could disrupt operations, while collisions with debris are a major worry \u2013 rather offsetting the fact that space-based data centres don\u2019t have to fear earthquakes or floods.<\/p>\n\n\n\n Advanced shielding could protect against things like radiation and micrometeoroids, but it will probably only do so much \u2013 particularly as Earth\u2019s orbit becomes ever more crowded.<\/p>\n\n\n\n To fix damaged facilities, advances in robotics and automation will of course help, but remote maintenance may not be able to address all issues.<\/p>\n\n\n\n Sending repair crews remains a very complex and costly affair, and though the falling cost of space launches will again help here, it is still likely to be a huge burden for a few decades to come. In addition, disposing of data centre waste takes on a whole new level of complexity off-planet.<\/p>\n\n\n\n So while there is certainly great excitement around this potential answer to our need for ever more data centres, it\u2019s clearly as complex as it is compelling.<\/p>\n\n\n\n Hopefully, with serious effort into research and development \u2013 as well as global collaboration \u2013 this will eventually revolutionise the way we manage and process data. Until then, with apologies, we\u2019ll just have to watch this space.<\/p>\n\n\n\n Domenico Vicinanza<\/a>, Associate Professor of Intelligent Systems and Data Science, Anglia Ruskin University<\/a><\/em><\/p>\n\n\n\n This article is republished from The Conversation<\/a> under a Creative Commons license.
