Heat pump sales per 1000 inhabitants (2017)

Technology for a better society

• High market acceptance of heat pumps in Scandinavia

• Several Start-Up companies for HTHP

• Heat pumps "standard" solution for building heating (and cooling)

Energy price ratio

Technology for a better society

Price difference per kWh electricity vs. fossil fuel

• De-carbonized future requires increased used of (renewable) electricity

• Electricity is in many European countries more expensive than fossil fuel

Industrial Heat Pump Examples (Dairy)

Technology for a better society

• Combined heating and cooling

• Tested on TRL 6• Integrated on TRL8 in dairy

production (5 GWh / year) • Need for thermal storage

to match time-depending heat sink and source demand
