The MOST project aims to develop and demonstrate a zero-emission solar energy storage system based on benign, all-renewable materials. The MOST system is based on a molecular system that can capture solar energy at room temperature and store the energy for very long periods of time without remarkable energy losses. This corresponds to a closed cycle of energy capture, storage and release. The MOST project will develop the molecular systems as well as associated catalysts and devices to beyond state-of-the-art performance and scale. Further, the MOST systems will be combined with thermal energy storage (TES) in a hybrid concept to enable efficient and on-demand utilization of solar energy. The hybrid structure of the device, combining TES and MOST, enables the operation of the system in two different modes, targeting different applications. In mode A, the objective is to reach a stable thermal output. In this operation mode, the MOST system is used to mitigate the daily variation in solar flux which consequently leads to a variable output of the TES. In operation mode B, the system is targeting larger temperature gradients under shorter durations of time. Mode A is simulating applications where a stable temperature output is needed, such as e.g. heat to power generation. Mode B is simulating operation where the system operates as a part of a larger energy system where the task is to mitigate variations in energy demand and energy production. The materials production features scalable, green chemistry production routes. Further, the project will build an innovation ecosystem around the project and engage with future users of the technology in order to ensure future development and EU capacity for future market implementation.

The need for thermal insulation pertaining to space applications, e.g., satellites and launch vehicles, demands the requirement for the components of the satellite or launch vehicles to remain within the operating temperature range throughout the life of the satellite or the course of the journey. The project ISBA proposes to develop a disruptive technology through seven different applications in the space sector, based on aerogels or xerogels which will be used as a new thermal insulation solution in order to make it competitive, clean, compact, easier to produce and assembly. In the specific domain of space, the impact of the project will enable an amplified profit at product level, allowing to design new concepts, way lighter, by avoiding secondary structures for maintaining MLI layout or rigid shield, and cheaper than the reference solutions. The technology thus assembled will guarantee a level of cleanliness compatible with the level of requirements of space applications, which will be one of focal points of ground-breaking developments. Thus, the overall objectives of the project can be summarized as follows: (i) Develop aerogel/xerogel-based solutions for cryogenic, moderate and high temperature space applications, (ii) implement additive manufacturing technologies specifically for aerogels in space applications, (iii) develop coating-technologies on aerogels/xerogels for operating in space environments, (iv) improve cleanliness of aerogels by developing enveloping technologies tailored for aerogels, (v) enhance industrial competitiveness of aerogel/xerogel solutions in space, and (vi) present EU-efficient alternatives to the current MLI solutions, thus reducing dependency on US technologies. To achieve these objectives, a consortium of three major end-user industry partners from EU, five major research and development centers focusing on aerogels, ceramics, and coatings, and one industry partner experienced in packaging technologies is established.
