Ballard Power Systems says it has appointed Randall MacEwen president and CEO to replace John Sheridan, who is retiring at year-end after having occupied the positions since 2006.
To support the transition process, Sheridan will continue to serve as an employee in an advisory capacity and on the board as a director until Dec. 31.
MacEwen, who has extensive executive-level experience in the clean energy sector, previously served as executive vice president of Stuart Energy Systems Corp., an on-site hydrogen production company; CEO of Solar Integrated Technologies Inc., a manufacturer and installer of commercial solar systems; and founder and managing director of NextCleanTech LLC, a clean energy consulting firm.
