3 Introduction 3

4 Datacenters - generalities Datacenter customers profiles: Telecom & IT (~36%) Bank, Financial Services, Insurance (~20%) Government (~10%) Healthcare (~14%) Energy (~13%) Architecture: IT rooms represent around 50% of total datacenter size Other 50% are occupied by: HVAC; Genset, UPS and batteries, humidification and deshumidification equipment; pressurization, control room 4

5 Datacenter UPS architecture / Example Battery rooms are in separated rooms than equipment Often with re-inforced floor Mainly lead acid batteries, series parallel connections Example of lead acid battery room in IBM/Kodak datacenter: Exide battery racks 5 Source:

16 Intensium Flex System High Power Advantage of use with Saft Lithium-Ion solution Combined with its long calendar/cycling life = Reduction of TCO 16

17 Life Cycle Assessment for batteries 17

18 What is a Life Cycle Assessment? LCA: overall evaluation of environmental impacts through the life cycle of products: 1) Cradle-to-gate 2) Cradle-to-grave 3) Cradle-to-cradle It is a product-oriented method for sustainability analysis Concept is to compare on function: > Need to define comparable system outputs =service provided 18

19 LCA methodology based on ISO s standards LCA is the detailed analysis of INPUTS & OUTPUTS that gives you the information you need to make the most environmentally friendly decisions throughout product life cycle. 19

20 Main impact categories agreed worldwide PED (Primary Energy Demand): the total amount of primary energy extracted from the earth (in MJ) Production of Materials GWP (Global Warming Potential): A measure of greenhouse gas emissions, such as CO2 and methane (in kg Production of Vehicles CO 2 equivalent) Non renewable energy resources Production of Materials Train Operation & Maintenance ODP (Ozone Depletion Potential): A measure of emissions of CFCs and halons that caused the reduction of ozone levels in atmosphere (in kg R11 equivalent) Non renewable energy resources Production of Vehicles Recycling of Vehicles Renewable energy r Train Operation & Maintenance Renewable M Rail Vehicles AP (Acidification Potential): A measure of emissions that cause acidifying effects to the environment (in kg Rail SO 2 Vehicles equivalent) Waste Waste EP (Eutrophication Potential): A measure of emissions that cause the over-enrichment of water and soil by nutrients such as nitrogen, phosphorus (in kg phosphate PO 3-4 equivalent) Emissions Emissions Recycling of Vehicles 20

21 Comparative LCA for lead-acid and Li-ion batteries with critical review according to ISO Battery use: back-up function located within a decentralized bay of dc network. The battery is in a closed rack located where there is no air conditioning. 2. The LCA analysis includes the manufacture, the use and the end of life over the course of the standby power service over a fifteen year period. 3. To allow comparison between Lead-acid VRLA and Li-ion NCA, the functional unit is defined for the same energy storage size 4kWh COLD SCENARIO : 20 C: HOT SCENARIO : 35 C: 21

22 Total energy extracted from the earth: PED (Primary Energy Demand) measured in MJ There is 4 times less total energy extracted from the earth between lead-acid and Li-ion batteries. At 35 C 22

23 Green house gas emissions like CO2 and methane: GWP (Global Warming potential) in kg CO2 equiv. At 20 C or at 35 C, Saft Li-ion batteries allow a decrease of 60 to 64% of Global Warming Potential (ie CO 2 and methane emissions) 23

24 Reduction of Ozone levels ODP (Ozone Depletion Potential) measures CFCs and Halons, values in Kg R11 equivalent 100% 11% 24 Environmental impact of Saft Li-ion batteries

25 Acidification of the environment AP (Acidification Potential) measured in kg SO2 equiv. 100% 38% 25

26 Over enrichment of water and soil Nitrogen, Phosphorus- EP (Eutrophication Potential) measured in Phosphate equivalent kg PO 4 3- eq 100% 100% 44% 48% 26

27 Summary: Green Li-Ion NCA batteries Total energy extracted from the earth: VRLA requires 4 times more energy than Lithium-Ion NCA Green house gas emissions like CO2 and methane: VRLA emissions are 1.7 times higher than Lithium-Ion NCA Reduction of Ozone layer VRLA impact on ozone level is 10 times higher than Lithium-Ion NCA Acidification of the environment VRLA acidification impact is 1.7 times higher than Lithium-Ion NCA Over enrichment of water and soil Nitrogen, Phosphorus- VRLA impact is more than 2 times Lithium-Ion NCA 27
