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?

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. But by the 1950s, clocks with improved batteries and oscillating quartz crystal resonators began to replace consumer electric clocks that synchronized with the power grid.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.
