Communication = ENERGY consumption

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

Competitive cost and efficient energy storage

technology


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


HEAT : sun, combustion (gas, liquid, solid)industrial wast heat sources

Mechanical work and electricity production

Working gas = air, nitrogen, helium

- Variety of fuels- Long lif time (40 000 hours)- Less noisy … than Diesel engine- Clean combustion (heat applied externaly)- Low maintenance level- High thermal efficiency (35% - 45%)

Why Stirling engine ?

Stirling cycleClosed thermodynamic cycle in which a working gas is alternatelycompressed at low temperature and expanded at high temperature

Conclusion and perspectives

Scientific collaboration - FEMTO-ST and Orange Labs (2006…)

o Power : electricity production- Engine for electricity production

from 100 W to 1 kW for microcogeneration application

- Competitive cost < 3 €/Watt (efficiency, performances, manufacturing).

- Efficient mechanical technology- Robustness (operating range, start up, idle, stop)

o Cooling technologyo Heat pump (heating and cooling) :

o Futur program (French Research call, FUI) : GINSENG research program Gestion INtelligente de Système d’ENergie en courant continu avec co-Générateur et stockage innovant (du pico au micro réseau)
