  • SkySails Power will be shipping first unit this week
  • Creating new jobs at sites in northern Germany

Hamburg, Germany, 25th of February, 2021

The Hamburg-based company SkySails Power GmbH is ready to deliver the first PN-14 airborne wind energy systems. The first unit of this pre-series will be shipped to Asia from the port of Hamburg this week. Further units for projects in Germany and on the island of Mauritius are on track for the first half of 2021.

The final assembly of the airborne wind energy systems takes place in Seevetal, Lower Saxony. The ground stations, weighing in at roughly 20 tons, are manufactured in a 900-square-meter production hangar along with the power generation unit and the kite’s launch and landing mast. It has already become apparent that the production facility’s current capacity will have to be significantly expanded in the coming years. SkySails Power GmbH currently employs around 90 people at locations in the Hamburg metropolitan area, Schleswig-Holstein and Lower Saxony. “We will be creating numerous additional jobs in northern Germany in the coming years. Here at the Seevetal site, the focus will be on employing skilled workers in electrics and mechanics”, says SkySails CEO Stephan Wrage.

Hi @rschmehl , indeed there are some informations on:

BASELOAD ONSHORE WIND POWER THAT’S AVAILABLE ANYTIME AND ANYWHERE

The SKS PN-14 harnesses the wind at an altitude of 200 to 400 meters and also achieves high yields at low-wind sites. The system is safely employable in hurricane and typhoon regions, as it is easily retrieved and stowed away before these natural disasters occur. Thanks to its simple transportation and installation requirements, the SKS PN-14 can also be installed in places that are difficult to access.

The SKS PN-14 achieves a high amount of full load hours (up to 6,000 full load hours/year). It is the first time a renewable energy alternative can compete with conventional solutions such as brown coal for supplying baseload power.

TECHNICAL DATA SKS PN-14
Average cycle power / rated power 1
80-200 kW
Kite size (laid out) 1
90-180 m²
Operating wind range
3-25 m/s
Tether length

Are there test reports with wind speeds, duration of reel-out and reel-in phases, power generated during reel-out phase, energy consumption during reel-in phase?

Nice to hear, after a gap of a couple of years, one of these products is supposedly flying somewhere. “You may see a kite”… and I guess you may not? Not to rain on anyone’s parade, but you must have begun to realize articles like this love to provide minimal details of the actual subject matter, quickly veering off into discussions of “the vast potential of wind energy”. Quickly steering the one-way “conversation” about their product away from any details of performance to generalities about “how much power is up there”, quoting a source or two, has always been the retreat of articles promoting newfangled wind energy hopeful-breakthroughs. The one that comes to mind for me is “Windtree” which was literally promoting photos of those round spinning roof vents with many fins as building-mounted wind energy systems, and selling “territories”. Selling “territories” was one more way of diverting attention from the product - all the hucksters needed was to keep insisting on the vastness of the wind energy resource, deftly bypassing any discussion of their actual product. The unspoken “nitty-gritty detail” of how much power their photos of roof vents were (not) making was avoided, as though, somehow the audience had missed that detail, but no worries, the story went on as though the efficacy of the product was well-understood and well-demonstrated. Anyway, we here know better than to think an article is equivalent to some sort of performance assessment meaningful to technical people. It is a fluff article intended for general readership, with the kind of “clickbait” appeal to draw in some eyeballs and continue “the narrative”. :slight_smile:

Some tests were performed and reported on several topics.
