WS 4.1 Investors’ role in different parts of the value chain of heat pumps

Organizers: Monica Axell, Caroline Haglund Stignor, Heat Pump Centre (HPT TCP)

Background

To reach the climatic ambitions, investment in clean energy need to more than triple by 2030 in clean electricity generation, energy infrastructure and end-use, such as new clean, efficient equipment and renovation, etc. This will result in an increase in global GDP. According to IEA, the number of heat pumps needs to be tenfold by 2050 and increase by a factor of 3-4 if the Net Zero emission target by 2050 shall be met, which requires extensive investments in the whole value chain of heat pumps. Channeling private investment to the transition to a climate-neutral economy as a complement to public money would accelerate the energy transition. Private investors are “betting” on clean energy technology, with improved security of supply – a future safe investment!

About the workshop

During the workshop, representatives from different stakeholders will share their views on possibilities and barriers related to investments in the value chain of heat pumps- what could spur such investments and what hinders them? During interactive discussions with the audience, we will explore where the most prominent bottlenecks for accelerating the roll-out of heat pumps are and where different types of investors could make a difference, while making a beneficial investment.

WS 4.2 The role of public and private funded projects to tenfold the number of heat pumps

Organizers: Monica Axell, Caroline Haglund Stignor, Heat Pump Centre (HPT TCP)

Background

One of IEA’s key messages in the report “The Future of Heat Pump”, released in November 2022, is that heat pumps are the key solution to reducing natural gas use for heating, supporting energy security, cutting emissions and keeping energy bills affordable. To reach the climate ambitions of IEA’s Net Zero Emissions by 2050 scenario, 50% of the heating needs in buildings should be covered by heat pumps in 2045. This would mean a tenfold increase compared to today and an increase by a factor of 3-4 already in 2030. To reach these ambitions investments in clean energy technologies and infrastructure will be needed, both from the public and the private sector, as well as policies which stimulate the energy transition. Wisely designed public investments, sometimes in combination with private funding, can contribute to removing barriers and spur the transition.

About the workshop

The aim of the workshop is to inspire representatives from the public sector and industry to learn from good examples and to provide an improved understanding of how to optimize public investment and how different types of public (or public/private) funding can make a significant difference depending on the stage of market maturity. During the workshop, representatives from different stakeholders will share information about and experiences from different types of public or public/private investments designed to stimulate an accelerated deployment of clean energy technologies such as heat pumps. These interventions will be followed by a panel discussion with representatives from the public sectors as well as from the industry.
