When people ponder about how will their house look like 30 years from now, they tend to think about sophisticated smart gadgets, technological innovations, or home robots. However, this question permeates the world of sustainability as well. Materials often take the centre of the scene, with innovative circular alternatives alongside more efficient construction techniques able to lower the impact of cement on the environment. The moment has come to spring clean our discourse around what is going to heat our buildings in 2030. In this briefing we explore what role the different energy carriers have to play in keeping our homes warm 30 years from now. Looking at the modelling to 2050 it appears quite clearly that hydrogen will play only a marginal role in heating European buildings. On the contrary, electricity will be the main energy carrier delivering this service, through heat pumps (individual and in district heating networks) and resistant heaters. To ensure a gradual uptake of electric heating systems, with the goal of fully decarbonising the building sector before 2050, it’s crucial to scale up renovation from today and ensure that the grid will be able to cope with the electricity demand.
