The Most System
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. 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. Specifically, hybrid solar collectors utilizing up to 80% of incoming solar energy will be designed and tested together with heat release devices, that combine MOST with thermal energy storage (TES) enabling rapid temperature ramp-up cycles delivering large temperature gradients.

For a Better Future
The materials production will feature 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. EU is now the leading actor in the development of MOST (also referred to as “Solar thermal Fuels, STF”). The partners in this consortium account for ≈80% of EU research output in the field during the last 5 years. With this proposal, we combine some of the strongest research teams in order to build on and extend EU’s world leading role in the development of MOST systems.
Sunlight in a bottle
Our technology allows for the capture and storage of light energy as chemical energy. This means that we could use this energy even when the sun is not shining. Our molecules are able to store the energy up to 18 years!.
We will design new devices with three key parts:
Solar energy collector
Heat release device
Molecular systems
Within this project, we will go beyond current state-of-the-art technology to help shaping the future of clean energy.

Research
Our consortium is responsible for the main part of the R+D in Europe around the topic of Molecular Solar Thermal Systems.

Outreach
We are working to offer new solutions to a key societal challenge. We want you to help us to spread the word.

Team Work
One objective, different visions. A joint effort of different countries and research teams to achieve a sustainable future.

Prototypes
Our technology is already alive! The first devices have been built and results are promising.
