The campus is planned as a large-scale data center hub requiring extremely high power reliability. FlexBase first disclosed the 500 MW vanadium battery plan in 2024 and obtained a local building permit a year later.<\/p>\n<p>The installation will begin at 1.5 GWh of capacity, with the modular design allowing expansion to 2.1 GWh. According to Energy-Storage.news, no flow battery project worldwide has previously reached this scale; the largest deployments to date have been in China, where state-directed policy promoted storage diversification and supply-chain security.<\/p>\n<p>The project&#8217;s site requires continuous discharge beyond eight hours \u2014 a duration window where flow chemistry holds clear advantages over lithium-ion. The key differentiators:<\/p>\n<ul>\n<li>Capital costs run higher than lithium-ion equivalents, yet the levelized cost of storage comes out lower over the system&#8217;s full service life<\/li>\n<li>No cell degradation, so capacity stays stable without replacement cycles<\/li>\n<li>No thermal runaway or fire risk, a decisive factor for a critical data center environment<\/li>\n<\/ul>\n<p>In vanadium flow systems, energy and power are physically separated: liquid vanadium pentoxide electrolyte stored in tanks sets the energy volume, while the battery stack, pumps, and controls determine discharge rate. Scaling capacity means adding tanks and electrolyte \u2014 not duplicating power electronics as with lithium-ion.<\/p>\n<p>Invinity&#8217;s globally installed fleet has now collectively delivered more than 10 GWh to customers. The Laufenburg project is expected to serve as the first proof point for gigawatt-class vanadium deployments outside Asia.<\/p>\n<p style=\"margin-top:1.5em;font-size:.9em;color:#555\">Source: <a href=\"https:\/\/www.energy-storage.news\/invinity-confirms-epc-contract-award-for-2-1gwh-landmark-flow-battery-in-switzerland\/\" target=\"_blank\" rel=\"noopener\">Energy Storage News<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Swiss data center campus is set to host the biggest vanadium flow battery installation ever built, pushing long-duration storage technology into a market long dominated by Chinese projects.
