ADEME[1] (French Agency for environment and energy control) provides funding for R&D&I in technologies with a positive impact on low-carbon mobility that are not exclusively dedicated to aeronautics (e.g. hydrogen technologies).
Funding for R&D&I projects is done through grants and repayable advance. This choice between grants and repayable advance will depend on the nature of the work financed, the nature of the beneficiaries and the amount of aid corresponding to the development of the products, processes or services.
The maximum intensity of ADEME rate of funding varies depending on the type of beneficiary and the type of research. For an ISE & a large company this varies from experimental development at 25% to fundamental research which can be financed at 50%. For SMEs, this starts at 45% for experimental development up to 70% for fundamental research. Finally, RTOs and research universities are 100% funded.
