Project description
Novel photomaterials for thermal management
The goal of the EU-funded PHOTHERM project is to fundamentally change how heating and cooling are generated by developing a new class of materials that capture, store and release both solar and ambient heat. The solar thermal management materials comprise molecular photo-switches that capture and store sunlight, so-called MOST systems, as well as phase change materials (PCM) that contribute to thermal management. The input of the MOST system is photons from sunlight and also ambient heat, as the PCM materials can absorb heat from the environment. The MOST-PCM combination has the potential to disrupt how temperature is controlled in a wide range of applications, including local power production, electronics systems, automobiles and housing.
Objective
Since the beginning of civilization, humanity has built houses to sustain comfortable living conditions throughout the seasons. In our modern society, about 50% of the total energy consumption is used for heating and cooling. Growing demands for thermal management in many different sectors, from electronics to housing, inevitably means increased energy consumption. The primary source of heat is coming from the combustion of fossil, bio, or waste-based feedstocks, all contributing to emissions. This project seeks to fundamentally change how we generate heating and cooling by developing a new class of materials that capture, store, and release both solar and ambient heat. The solar thermal management materials are a unique combination of molecular photo-switches that capture and store sunlight, so-called MOST systems, together with phase change materials (PCM) that can contribute to thermal management. The two classes of materials operate at fundamentally different principles. The input of MOST system is photons, whereas the output is heat. The PCM materials can absorb heat from the environment. By combining the two materials into one, we can harness and upgrade two of the most abundant renewable sources of energy on the planet: ambient heat and sunlight. The materials function will be demonstrated in heat to power devices that can operate 24/7 without the need for traditional batteries. The MOST-PCM combination has the potential to disrupt how we control the temperature in a broad range of applications, from local power production to heating and cooling in electronics systems, to temperature control in automotive and housing. The materials developed in this project have the potential to radically change thermal comfort and energy consumption and give new design opportunities to thermal management systems from the 10-9 to 10 m length scale.
