Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix. Or is it better to liquefy it on site at the airport?

The EV Transition Explained: Policy Roadblocks

Cars That Think

“Public policy implementation is hard even if everyone supports a policy,” says University of Michigan professor emeritus John Leslie King , who has studied policy management and administration for decades. Permitting issues also bedevil wind power projects. For example, Iowa is one of the best states for wind power farms.
