Here are a couple of the designs Boeing is now looking at for a HALE UAV. It would be powered by automotive engines converted to burn hydrogen and have an endurance of seven days at 65,000ft. Boeing is working with Aurora Flight Sciences, which is developing and testing the engine for its single-engined, hydrogen-fuelled Orion HALL (high altitude, long loiter) UAV, now under construction.

Wonder if these designs had anything in common with the Boeing Phantom Eye; the Orion UAV flew on August 24, 2013 and was later placed in company storage in September 2015, but is reportedly being earmarked to fly again in response to Air Force and Coast Guard requirements (https://www.flightglobal.com/news/a...orion-uav-production-for-2019-deliver-435898/).

Orion started its life as a hydrogen-powered single engine HALE, but was later converted to twin engine MALE, using two Austro AE300 Diesel engines of about 167shp.
It has demonstrated an endurance in excess of 80 hours, the payload is in the vicinity of 1,000 lbs, mostly comms and sigint gear.
