CRESYM is a non-profit association, gathering industrial & academic research organisations and aiming at solving the coming challenges for the future, fast-evolving European energy system.

We foster collaborative R&D works to deliver opensource energy system simulation tools

We foster efficient collaborations on low-TRL R&D issues of general interest.
We promote, and rely on, opensource principles.
We shall maintain useful technological building blocks available for all researchers & engineers.

Ongoing projects


MUESSLI aims at “smart-linking” simulation tools to perform cross-sector, actually scalable, simulations and enable the optimal development and operation of an holistic “energy system” (power, heat, transportation, etc.) with electricity and hydrogen as main carriers.
