Duurzaam Ameland:
Ambition: ‘leader in the energy transition in 2020’: • 15-20 years ahead
• 70-75% reduction of CO2
• Use the existing energy network (gas and
electricty)
Overall goal:
Together we invest in
the energy management
of the island Ameland,
being the blueprint for
many villages in or even
outside the
• Ambition: Ameland is frontrunner: 15 to 20 year ahead
in National transition goals
• For 8 years already Ameland has been working on
sustainability projects. Major achievements realised.
• Ameland as an example.
Projects:
• Injection of Hydrogen
• Mini CHP’s (5 kWe)
• Gas Heat Pumps
• Micro CHP’s (1 kWe)
• CNG Fuel Station
• CNG in Auto busses
• LED street lighting
• 45 Fuel Cells (1.5
kWe)
• Hybrid Heat Pumps
• Solar park (6 MWe)
• Murata e-storage
• Combination of a condensing boiler and a small electric heat pump
• Use only gas if necessary (when output HP is to low)
• Source of the heat pump:
• Outdoor air
• Ventilation air
• A combination of both

Question 1
What is the CO2-reduction (in %) of a household (3 persons) when a hybrid heatpump has been placed instead of a condensing boiler and the used electricity for the heatpump is CO2-neutral?
Household: 1500 m3/yr natural gas total space heating and domestic hot water 100 m3/yr natural gas for domestic hot water per person
Hybrid heatpump runs only for space heating
Hybrid heatpump decreases gas demand with 70% 1 m3 natural gas gives 1.8 kg CO2
Answer 1
1500 m3/yr x 1,8 = 2700 kg/yr CO2
1500 – (3 x 100) = 1200 m3/yr gas for space heating 1200 x 0,7 = 840 m3/yr less gas
1500 – 840 = 660 m3/yr gas left 660 x 1,8 = 1188 kg/yr CO2
Question 2
How many PV-panels (solar panels) are necessary to feed the heatpump with CO2-neutral electricity?
1 m3 natural gas is equal to 10 kWh COP of the heatpump is 4
1 kWh (electricity) input gives 4 kWh (heat) output, 3 kWh comes from ambient air 1 PV-panel gives 210 kWh/yr electricity
Answer 2
840 m3/yr less natural gas 840 x 10 = 8400 kWh/yr heat
8400 / 4 = 2100 kWh/yr input heatpump 2100 / 210 = 10 PV-panels
Question 3
What is the CO2-reduction (in %, compared with a power plant) when a fuel cell with an average output of 1 kW runs continuously and all the heat of the fuel cell can be used efficiently?
Fuel cell: output 500 – 2000 Watt, average 1 kW electricity efficiency 60%
overall efficiency 90% 1 m3 natural gas gives 1.8 kg CO2
Answer 3
8760 x 1 = 8760 kWh/yr
8760 / 0,9 = 9730 kWh/yr input fuel (natural gas) 9730 / 10 = 973 m3/yr natural gas
973 x 1,8 = 1752 kg/yr CO2
8760 x 0,5 = 4380 kg/yr CO2 (power plant) ((4380 – 1752) / 4380) x 100% = 70% less CO2
