The return of the airship – from THE WEEK

Transportation is now the biggest single source of U.S. greenhouse gas emissions, having recently passed electricity generation. Worse, zero-carbon transportation technology is only in its early stages — especially for air travel and shipping, which accounts for large and growing share of emissions.

Steampunk fans and climate hawks alike want to know: what about airships? After investigating the subject for a time, I’ve come to a tentative conclusion that airships could indeed play an important role in a zero-carbon transportation infrastructure — but probably not in the form of romantic luxury travel. Big and weird cargo shipping might just be where the airship does best.

Airships are, of course, aircraft which use a large envelope of lighter-than-air gas, typically hydrogen or helium, to provide most or all of their lift. There are three basic types: non-rigid (a blimp), or semi-rigid (with a partial supporting structure), or rigid (with a complete supporting structure). There is also the hybrid airship, which is slightly heavier than air and uses traditional wings or rotors to provide lift and control.
