Cryogenic, superconducting conduits could be connected into a “SuperGrid” that would simultaneously deliver electrical power and hydrogen fuel

From the page:
“It is not at all clear, moreover, how well today’s infrastructure could support the rapid adoption of hybrid vehicles that draw on electricity or hydrogen for part of their power. And because the power system must continuously match electricity consumption with generation, it cannot easily accept a large increase in the unpredictable and intermittent power produced from renewable wind, ocean and solar resources.

We are part of a growing group of engineers and physicists who have begun developing designs for a new energy delivery system we call the Continental SuperGrid. We envision the SuperGrid evolving gradually alongside the current grid, strengthening its capacity and reliability. Over the course of decades, the SuperGrid would put in place the means to generate and deliver not only plentiful, reliable, inexpensive and “clean” electricity but also hydrogen for energy storage and personal transportation.”

It’s about time we got the Hydrogen Economy going in earnest, once we do we can let the Middle East sort out it’s own problems.
