Issues related to fuel cells and hydrogen energy will be the focus of two events to be held during October. On Oct. 9 and 10, the California Hydrogen Business Council will hold its second annual fuel cell summit at the Sacramento headquarters of the state’s Environmental Protection Agency. Later in the month, the South Carolina Hydrogen and Fuel Cell Alliance will host its 2013 Fuel Cell Seminar and Energy Exposition in Columbus, Ohio. The event, which occurs on October 21 to 24, will include tours of industry and research facilities, multiple hydrogen and fuel cell presentations, ride-and-drive opportunities, and ground mobility plenary sessions, according to the group’s website.
