FEATURE THE ENERGY TRANSITION FACING THE DATA CENTRE AND ICT SECTOR COULD THUS OFFER UNEXPECTEDLY GREAT OPPORTUNITIES – NOT IN THE LEAST FINANCIALLY. are now more than six months further in and it is becoming increasingly clear how important this project is – especially for the data centre industry. This project is not only about storing energy in batteries. In order to justify the relatively high costs of batteries, we need to develop a business case that is as broadly defined as possible. In other words: the batteries should be used in as many ways as possible so that the investments can be recouped. Robbert Hoeffnagel, Green IT Amsterdam 36 Issue 05 That is precisely the phenomenon that makes this project very relevant for data centres, which are now also discussing the possibilities that arise from integrating batteries and UPS systems with the energy networks of grid operators. 80%. This decline means that the batteries are no longer suitable for use in an electric car and therefore need to be replaced. A subsidiary of the Johan Cruyff Arena – called Amsterdam Energy Arena BV – has invested in a room filled with 61 racks full of batteries. These come from Nissan’s electric car – the Leaf. It turns out, however, that these batteries are still perfectly suitable for storing electrical energy in, for example, an energy storage system linked to solar panels. After a number of years, the capacity of the batteries of these cars drops from 100% to What to do with so many ‘useless’ car batteries? The Amsterdam Arena has now installed 61 racks with 590 battery packs. Good for 3 MW and 2.8 MWh. www.intelligentdatacentres.com
