German Company for Disruptive Innovation supporting growth of high-altitude on-shore wind generators


Among the many tasks being funded by the German Company for Disruptive Innovation (SPRIND) is an effort by Horst Bendix to develop a high-altitude, on-shore wind turbine. The upper a wind turbine is put in, the extra effectively it is going to work, as a result of the wind is way steadier and blows with higher power at altitude.

Nonetheless, typical wind generators are topic to excessive dynamic masses because of the large weight of the nacelle at hub peak. There’s virtually no method to construct them taller, as they might be too unstable and economically too pricey.


Bendix, who was answerable for know-how and analysis at heavy-equipment producer Kirow, has designed a model of a high-altitude wind turbine for low-wind, onshore use with a hub peak clearly larger than every thing else constructed so far.

Bendix’ innovation embrace:

  • The generator is now not positioned within the nacelle, which implies the brand new and far taller tower is not any heavier than the present ones.

  • The tower’s mass now not will increase disproportionately to its peak.

  • The tower is constructed utilizing commonplace metal pipes which are available and conveyable.

All of this ends in a discount of tower weight by 50%, and a discount of complete funding prices by 40%. Trimming manufacturing prices drastically cuts the prices per megawatt hour of energy generated.

SPRIND GmbH was based in Leipzig in December 2019. The company is a versatile and quick state funding instrument with which the Federal Ministry of Schooling and Analysis (BMBF) and the Federal Ministry for Financial Affairs and Local weather Safety (BMWK) need to help and speed up the identification and growth of revolutionary concepts.

For the start-up part 2019-2022, funds of at the least €151 million had been budgeted. The company is initially deliberate as an experimental effort for a interval of ten years. For this ten-year time period (from 2019), a complete finances of €1 billion is predicted.
