IEA SHC Task 52: Solar Thermal’s Role in 2050 Energy Mix

Submitted by Baerbel Epp on September 29, 2017
Collector Installation in HamburgWhat role solar thermal will play in the energy sector in 2050 is one of the principal questions that the international Task 52 research project Solar Heat and Energy Economics in Urban Environments intends to answer. As part of this IEA Solar Heating & Cooling Programme task, Denmark’s Aalborg University chose four major solar thermal countries in Europe – Austria, Denmark, Germany and Italy – to model their 2050 solar share in national heat production. The university’s estimates range from 3 to 12 % based on country and scenario, which would require 4 to 175 million m² of collector area in each of the four nations. The solar share of all four was rather similar in high penetration scenarios, although climate, energy demand and network design vary significantly. That’s why the researchers from Aalborg concluded that “the findings can be applied to a variety of energy systems, including in countries that are not directly part of this study.” They also underlined the importance solar thermal could have in reducing pressure on scarce resources such as biomass.
