TECHNOLOGIES ROADMAP
Well-known and used technology
European codes and standards
Primary energy reduction/ standard boiler
1990 2000 2010 2020
Boiler
Absoprtion gas heat pump (domestic)
Gas heat pump (commercial)
Micro-CHP with fuel cell
+ renewable energy solutions (thermal solar, PV,…)
Low temperature boiler
Electric appliances
Condensing boiler
Micro-CHP (stirling)
Hybrid heat pumpElectric heat pump

GAS HEAT PUMP : TWO TECHNOLOGIES TO COVER THE RESIDENTIAL AND COMMERCIAL SECTORS
Available on the market for commercial buildings and collective dwelling
In last development stage for individual housing
Gas engine driven heat pump
Absorption heat pumps
high efficiency : 150% for heating and 140% for cooling
very high energy efficiency in heating : about 165 % for the aero thermal HP and 170% for the geothermal HP
5
MICRO-CHP : TO PRODUCE SIMULTANEOUSLYHEAT AND ELECTRICITY
Two technologies : stirling engine already available covers 100% of the heating needs and hot water, and 50 to 70% of the electricity needsfuel cells expected from 2015
Total production efficiency (heat & electricity) = 105%
A new way to monitor electricity demand via virtual power station
Smart electricity and gas networks convergence
