In this panel with recognised data centre experts, we will explore the building blocks of a data centre where heat reuse and decarbonisation are fully optimised. We will cover all decisive elements in detail, such as liquid cooling (direct-to-chip & immersion cooling), IT dematerialization, incl. circular economy hardware and heat harvesting & reuse. In addition, David & Stefan, as former volunteer leaders of the EMEA OCP community, together with their fellow professionals from the data centre industry, will provide insights into the latest innovations & technologies and thus an outlook into the near future of the industry.
