ExerGo provides the the world\u2019s first CO\u2082-based energy network. Harnessing renewable resources and waste heat, the company uses CO\u2082 as a heat transfer fluid in a closed loop instead of water as in incumbent networks. Using CO\u2082 and its phase change between liquid and vapor, the network is up to nine times denser, allowing the use of smaller, flexible pipes. At its pilot plant in Sion, Switzerland, ExerGo sources clean energy from underground water. Through existing heat pumps and exchangers, it delivers 1200 MWh heating and cooling per year, all-year round, since March 2022. Allowing heat and cold to flow bidirectionally, the network leverages surplus heat, which optimises heating and cooling needs between users of the three multi-storey buildings of the Energypolis Campus of HES-SO University of Applied sciences.<\/p>","protected":false},"author":1,"featured_media":3178,"template":"","awards-edition":[],"awards-country":[],"awards-categories":[25,27],"class_list":["post-3052","awards-projects","type-awards-projects","status-publish","has-post-thumbnail","hentry","awards-categories-heat-pump-city-of-the-year","awards-categories-winner"],"yoast_head":"\nThe world\u2019s first CO\u2082-based energy network - Heat Pump Forum & Awards<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/ehpa.org\/heatpumpforum\/?awards-projects=the-worlds-first-co\u2082-based-energy-network\" \/>\n<meta property=\"og:locale\" content=\"en_GB\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The world\u2019s first CO\u2082-based energy network - Heat Pump Forum & Awards\" \/>\n<meta property=\"og:description\" content=\"ExerGo provides the the world\u2019s first CO\u2082-based energy network.
