4 Communication = ENERGY consumption See - Session 1 : Pr. T. O Farrell s Energy Consumption Ratio (ECR) = J.Bit -1 - Session 3 : M. Renato Boldi, Eco-Efficiency Indicator : target 2015 = 4700 bit.j -1 - Session 4 : A. Andrae, Smart phones : over 2000 mill. mobiles for see all sessions in fact!! Energy challenges of Horizon 2020 : - Reducing energy consumption and carbon footprint - Low-cost, low-carbon electricity supply - Alternative fuels and mobile energy sources - A single, smart European electricity grid - New knowledge and technologies - Robust decision making and public engagement - Market uptake of energy and ICT innovation ETSI Annual report

5 Competitive cost and efficient energy storage technology 5

6 Fast extension of Telecom mobile network Stand-alone pure photovoltaic (PV) + battery system Hybrid system with Diesel-battery without or with PV They are issues of theft, cost of fuel, heavy maintenance More users are off grid and need electricity Hybrid renewable energy can be also good solution One solution is the Stirling engine An alternative power system 6

7 Stirling cycle Closed thermodynamic cycle in which a working gas is alternately compressed at low temperature and expanded at high temperature Working gas = air, nitrogen, helium Slider crank mechanism Stirling = 1816 Diesel = Mechanical work and electricity production Power piston Displacer piston HEAT : sun, combustion (gas, liquid, solid) industrial wast heat sources Why Stirling engine? - Variety of fuels - Long lif time ( hours) - Less noisy than Diesel engine - Clean combustion (heat applied externaly) - Low maintenance level - High thermal efficiency (35% - 45%) 7

8 Alternative power systems FEMTO-ST Micro-Stirling engine Stirling engine Ericsson engine 1 cm P elec < 1 W 100 W < P elec < 1 kw 1 kw < P elec 10 kw Fuel-cells 50 W < P elec < 10 kw 8
