Yesterday, Stellantis made public what its partners in the Symbio hydrogen mobility joint venture have known since May – it is discontinuing its hydrogen fuel cell technology development programme as of 2026. The vehicle maker informed it has “initiated discussions with the shareholders of Symbio to evaluate the current market consequences and to preserve the best interests of Symbio, in line with their respective obligations.” JV partners Michelin and Forvia believe this decision will have “irreversible operational and financial consequences for Symbio” and express concern about the impact upon the firm’s 640 employees.
