Cumulative capacity and capital cost index learning curve for vapour compression applications in the Sustainable Development Scenario, 2019-2070

Notes

SDS = Sustainable Development Scenario. Solid line for technology costs represents the cost trajectory in the Sustainable Development Scenario while the “no spillover” case is a counterfactual that shows the slower price decline that would be observed if the technology could not benefit from experience gathered in different applications. The cost excludes geothermal applications and is referred to heat-pumps unitary cost excluding additional components needed for the system and eventual ductwork. This cost trajectory is representative for units of less than 20 kW capacity.
