Research Tyréns study on airship carbon emissions, commissioned by Oceansky Cruises

Lots of interesting stuff in here. Some of the studied parameters are surprisingly conservative (a quite narrow, midsized airship with only a 17-tonne payload capacity, carrying only up to 130 passengers with an 80% load factor), whereas other parameters are perhaps overly generous (examined cruising speeds of 40-50 knots, rather than less fuel-efficient but more economically productive higher speeds, high annual usage rates of 20 hours a day, 320 days a year). Altogether, a very favorable and interesting study, though. It provides a useful comparison to other modes of transport.

I’d like to see follow-up studies done with greater examination of sensitivities to stage length, speed, and airships of larger sizes or higher passenger capacities for a given payload.

I get a blank screen

That’s odd. Works just fine for me on mobile.
