In 2014 the subsidiary Schottel Hydro was founded to bundle up the company activities in the hydrokinetic energy segment.

In the mid 1930s Becker bought part of the present-day company premises and founded Schottel Werft.

He named his enterprise after a section of the river Rhine which is called Auf der Schottel and located close by in Osterspai.

Soon, the rudderpropeller was known as a propulsion unit for small fast patrol craft for the German police and government.

In 2003, the Schottel Combi Drive was established with an electric motor which is vertically integrated into the support tube of the rudderpropeller.

Since Schottel developed the first Z-drive in the 1950s the product portfolio has been extended by a range of thruster types (selection).

It is also available as a hydraulically retractable system for open-water service, dynamic positioning or varying water depths and underwater mountable thruster for ships that need to reduce docking times.

[3] In 2014 Schottel introduced a rudderpropeller with an additional electric motor (PTI - power take in)[clarification needed] as a hybrid propulsion concept.

Additionally, the flow around the fins creates a lift component in the thrust direction, which has a thrust-enhancing effect.

Depending on the type of vessel, the range of application for Transverse Thrusters extends from harbor maneuvering to positioning tasks offshore.

In 2016, Schottel Hydro and its subsidiaries planned to install a tidal turbine array named TRITON in the Bay of Fundy, Canada.

[12][13] In 2017, Schottel Hydro scaled down its Bay of Fundy operations, going from the planned large turbine array to a smaller tidal platform made by Scottish company Sustainable Marine,[14] which was deployed in 2019.

[15] Schottel Hydro and Sustainable Marine merged later in 2019[16] and continued working in the Bay of Fundy until 2023, when the project was shut down.
