IEA TECHNOLOGY COLLABORATION PROGRAMME ON

HEAT PUMPING TECHNOLOGIES (HPT TCP)

International Workshop, Oslo, 10. May 2022
Stephan Renz, Chairman IEA HPT TCP
The HPT TCP is part of a network of autonomous collaborative partnerships focused on a wide range of energy
technologies known as Technology Collaboration Programmes or TCPs. The TCPs are organised under the auspices of theInternational Energy Agency (IEA), but the TCPs are functionally and legally autonomous. Views, findings and publicationsof the HPT TCP do not necessarily represent the views or policies of the IEA Secretariat or its individual member countries.

The IEA was created in 1974 to help co-ordinate a collective
response to major disruption in the supply of oil•

While oil security remains a key aspect of our work, the IEA
has evolved and expanded significantly since its founding•

Taking an all-fuels, all-technology approach, the IEA
recommends policies that enhance the reliability,
affordability and sustainability of energy

MissionThe IEA works with governments and industry toshape a secure and sustainable energy future for all

REDUCTION OF CO2 EMISSIONS BY 2050 BY SECTOR
CO2 emissions of the individual sectors andreduction paths. Strongest reduction
required for power supply. “Net zero" is tobe achieved (worldwide) as early as 2040.
This means that electricity for heat pumps
will also be CO2-free!

SPACE COOLING – DRIVER FOR INCREASE ELECTRICITY DEMAND

10.05.2022 / Stephan Renz, Beratung Renz Consulting, Baselwww.heatpumpingtechnologies.org

IEA’S 10-STEP PLAN TO REDUCE DEPENDENCE ON RUSSIAN GAS
Action 7 :Speed up the replacement of gas boilers with heat pumps• Heat pumps offer a very efficient and cost-effective way to heat
homes, replacing boilers that use gas or other fossil fuels.

Source: IEA, Paris, 2022 - All rights reserved.

• Alongside existing policy frameworks, targeted support forinvestment can drive the scaling up of heat pump installations ideally, in combination with upgrades of the buildings

10.05.2022 / Stephan Renz, Beratung Renz Consulting, Basel• Replacing gas boilers or furnaces with heat pumps is also an
attractive option for industrial applications, althoughdeployment may take longer to scale up.
• A shift from gas to electricity for heating buildings could have thecorresponding effect of pushing up gas demand for power
generation. However, any increase would be much lower thanthe overall amount of gas saved. Such a shift would also transfer
seasonal swings in demand from the gas market to the power
market.
